ABOUT THIS ARTICLE SmartySaaS helps SaaS and AI software founders make smarter financial decisions through practical, experience-backed content covering SaaS accounting, financial reporting, and financial metrics. This article has been reviewed by a Certified QuickBooks ProAdvisor and accounting professional with experience supporting over 350 SaaS businesses. Our goal is to provide practical, accurate, and actionable guidance that SaaS founders can use to make informed business decisions.

Most SaaS founders track the wrong numbers, or the right numbers calculated the wrong way. Stripe, accounting software, and product tools each produce their own reports, and every KPI guide seems to list twenty more. The result is a dashboard full of charts that still can’t answer the basic questions. Are we growing? Are customers staying? Is each customer worth what it costs to win them? How long will the cash last?

Founders don’t need more numbers. They need the right few, calculated the same way every month, with a clear goal attached to each one. That’s what turns a pile of data into something you can actually run a company on.

This guide covers the SaaS KPI metrics that matter most, grouped by the question each one answers. Every KPI comes with a simple formula and a worked example. You’ll also learn which ones fit your stage, how to set targets that make sense, and the calculation mistakes that quietly make numbers wrong. If you’re building an AI product, there’s a section on the extra KPIs your business needs that traditional SaaS guides leave out.

What SaaS KPI Metrics Are and Why They’re Different

A metric is any number you can measure. How many people visited your website. How many support tickets came in. How much money hit your bank account. A KPI, which stands for key performance indicator, is a metric you’ve decided is important enough to set a goal for and check on regularly.

Here’s a simple way to see the difference. “We got 400 trial sign ups this month” is a metric. “We want 8 percent of trials to become paying customers, and this month we hit 6 percent” is a KPI. The KPI has a target, so it tells you whether things are going well or not. A plain metric just sits there.

SaaS KPI metrics are different from KPIs in most other businesses because of how subscription companies make money. A store selling furniture makes its money when the sale happens. A software company makes most of its money after the sale, by keeping customers paying month after month. That means the most important SaaS numbers are about what happens over time. Are customers staying? Are they upgrading? How long does it take to earn back what you spent to win them?

It also means problems show up slowly and then all at once. A few extra cancellations each month don’t feel like much. But because you lose that revenue every month going forward, small leaks add up fast. Good KPIs catch those leaks early, while they’re still easy to fix.

The Five Areas Your KPIs Should Cover

Instead of tracking random numbers, think about your business as five big questions. Every useful SaaS KPI answers one of them, and together they give you a full picture of how the company is doing.

The first question is whether you’re growing. That’s covered by revenue and growth KPIs like monthly recurring revenue and annual recurring revenue. The second is whether customers stay, which is what retention KPIs like churn and net revenue retention measure. The third is whether each customer makes you money, covered by unit economics like customer acquisition cost, payback, and gross margin. The fourth is how long your cash will last, which burn rate and runway answer. The fifth is whether customers are happy and engaged, which shows up in product and customer KPIs like active users and Net Promoter Score.

Most KPI guides group these by department, like marketing, sales, and customer success. That’s useful for big companies with separate teams. For a founder running a small SaaS business, grouping by question works better, because you’re usually the one answering all five. It also makes it easier to spot when one area is hiding a problem in another. For example, strong growth can hide weak retention for months if you only look at the growth numbers.

Revenue and Growth KPIs

These are the SaaS KPI metrics most founders check first. They tell you how big the business is and how fast it’s moving.

Monthly recurring revenue

Monthly recurring revenue, or MRR, is the subscription money you can count on every month. To calculate it, add up what every paying customer pays per month. If a customer pays yearly, divide their annual price by twelve. One time charges, like setup fees or consulting work, don’t count, because they won’t repeat next month.

Say you have 300 customers on a $49 plan, 100 customers on a $149 plan, and 20 customers on a $499 plan. Your MRR is 300 times $49, plus 100 times $149, plus 20 times $499. That’s $14,700 plus $14,900 plus $9,980, for a total of $39,580.

The total is helpful, but the real insight comes from splitting MRR into pieces. Each month, new customers add MRR, upgrades add more, downgrades subtract some, and cancellations subtract the rest. Tracking those four pieces separately shows you exactly where growth comes from and where it leaks.

Annual recurring revenue

Annual recurring revenue, or ARR, is usually MRR times twelve. Using the example above, $39,580 in MRR equals about $475,000 in ARR. Investors use ARR as the headline number for your company’s size, especially once you’re selling annual contracts.

The key with ARR is consistency. Decide what counts, write it down, and stick with it. Some companies quietly include one time fees or count signed contracts that haven’t started yet. That makes ARR look bigger but creates problems later, when an investor’s accountant compares it to your actual books and the numbers don’t match.

Average revenue per account

Average revenue per account, or ARPA, shows how much a typical customer pays you. Divide MRR by your number of paying customers. With $39,580 in MRR and 420 customers, ARPA is about $94 a month.

Watch which way ARPA moves over time. If it’s rising, you’re either landing bigger customers or getting existing ones to upgrade. If it’s falling, you might be discounting too heavily, or your newest customers might be choosing cheaper plans. Neither is automatically bad, but you should know which one is happening and whether it was on purpose.

Trial or freemium conversion rate

If you offer a free trial or free plan, your conversion rate shows how many of those users become paying customers. Divide new paying customers from trials by the number of people who started a trial in that period, then multiply by 100. If 500 people started trials and 40 became paying customers, your conversion rate is 8 percent.

Conversion rates vary a lot depending on whether you ask for a credit card up front, how long the trial lasts, and how quickly users reach the point where your product clicks. The most useful comparison is your own rate over time. If conversion drops after a pricing change or a new onboarding flow, that’s a signal worth investigating right away.

Retention KPIs

Retention is where SaaS companies are really won or lost. These SaaS KPI metrics show whether customers stay and whether they spend more over time.

Customer churn rate

Customer churn rate shows what percentage of customers canceled during a period. Divide the number of customers who canceled by the number you had at the start, then multiply by 100. If you started the month with 420 customers and 12 canceled, your monthly churn is about 2.9 percent.

That might sound small, but monthly churn adds up quickly. Losing close to 3 percent of customers every month means losing roughly a third of them over a year, before counting any new sign ups. Always calculate churn against the number of customers you had at the start of the period, not at the end, or new sign ups will make your churn look smaller than it really is.

Revenue churn

Revenue churn measures how much money you lost instead of how many customers. Divide the MRR lost to cancellations and downgrades by your starting MRR, then multiply by 100. If you started with $39,580 in MRR and lost $2,500, your gross revenue churn is about 6.3 percent.

Revenue churn and customer churn can tell very different stories. Losing ten customers on your cheapest plan might barely move revenue. Losing one customer on your biggest plan could hurt more than all ten combined. Track both, and pay close attention when they move in different directions.

Net revenue retention

Net revenue retention, or NRR, answers one question. If you stopped signing up new customers today, would the customers you already have bring in more money or less money than they did a year ago?

Here’s how to figure it out. Take a group of customers who were paying you a year ago. Back then, they paid $30,000 a month. Over the year, some of them upgraded and now pay $6,000 more. A few downgraded and pay $1,500 less. Some canceled, taking $3,000 with them. Add it up and that same group now pays $31,500 a month.

Divide what they pay now by what they paid before. $31,500 divided by $30,000 is 1.05, or 105 percent. That means your existing customers are paying you 5 percent more than they did a year ago, without counting a single new customer. Anything above 100 percent means your current customers are growing your business on their own. Anything below 100 percent means you’re losing more from them than you’re gaining.

Gross revenue retention

Gross revenue retention, or GRR, is NRR’s stricter sibling. It counts only losses from downgrades and cancellations and ignores upgrades completely. Using the example above, start with $30,000, subtract $1,500 and $3,000, and you get $25,500. Divide by $30,000 and GRR is 85 percent.

GRR can never go above 100 percent, which is exactly why it’s useful. A company with great upgrades can have a strong NRR while quietly losing a lot of customers. GRR exposes that. If your NRR looks healthy but your GRR is low, your growth depends on a small group of customers spending more, and that can change quickly.

📌 From the Field One client of ours was proud of a 108 percent NRR and had it front and center in their pitch deck. When we calculated GRR for the first time, it came out at 78 percent. Most of their expansion was coming from just three large accounts that kept adding seats, while smaller customers were canceling at a steady pace. The founder hadn’t noticed, because the overall number looked great. They moved two people onto onboarding for smaller accounts, and over the next two quarters GRR climbed into the mid 80s, which made the whole growth story far more convincing to investors.

Unit Economics and Profitability KPIs

Unit economics answer a simple question. When you win a customer, do you make money on them, and how long does it take? These SaaS KPI metrics matter more and more as you spend serious money on growth.

Customer acquisition cost

Customer acquisition cost, or CAC, is what you spend to win one new customer. Add up all your sales and marketing costs for the period and divide by the number of new customers. If you spent $30,000 on sales and marketing last month and won 60 customers, your CAC is $500.

The hard part is being honest about what goes into the total. Ad spend is obvious. But salaries for marketing and sales staff, agency fees, sales software, and contractor costs all belong in CAC too. Many founders leave out salaries, especially their own time spent selling, and end up with a CAC that looks great on paper and is badly wrong in real life. If you’re doing the selling yourself, at least make a note that your time isn’t included.

CAC payback period

CAC payback period tells you how many months it takes for a new customer to earn back what you spent to get them. Divide CAC by the monthly revenue a new customer brings in multiplied by your gross margin percentage. Using gross margin matters, because you don’t get to keep every dollar of revenue.

Say your CAC is $500, a new customer pays $94 a month, and your gross margin is 80 percent. That customer brings in about $75 a month in profit before overhead. Divide $500 by $75 and payback is about 6.7 months.

For comparison, the 2026 SaaS and AI Performance Benchmarks from Aleph and Benchmarkit, summarized by ScaleXP, found a median CAC payback of 16 months for the B2B software and AI companies that reported it. The top quarter came in at 10 months, and companies selling plans under $5,000 a year had a median of 11 months. Payback is often more trustworthy than lifetime value for young companies, because it doesn’t depend on guessing how long customers will stay.

Customer lifetime value

Customer lifetime value, or LTV, estimates how much profit a customer brings in over their whole time with you. A simple version divides average monthly profit per customer by your monthly churn rate. If customers bring in $75 a month in profit and monthly churn is 2.9 percent, LTV is $75 divided by 0.029, or about $2,590.

Many guides say LTV should be at least three times CAC. In this example, $2,590 divided by $500 is about 5 to 1, which looks great. But be careful. LTV depends heavily on your churn rate, and if you’ve only been around a year, your churn estimate is shaky. Change churn from 2.9 percent to 4 percent and LTV drops to $1,875. Use LTV as a rough guide, not a precise number, until you have a couple of years of data.

Gross margin

Gross margin shows how much of each revenue dollar is left after paying the direct costs of delivering your product. Subtract cost of revenue from total revenue, divide by total revenue, and multiply by 100. For SaaS, cost of revenue usually includes hosting, third party software built into your product, customer support, and onboarding staff.

If you brought in $40,000 in revenue and spent $8,000 on hosting, support, and other direct costs, your gross margin is 80 percent. Traditional software companies tend to have high gross margins because serving one more customer costs very little. That’s one big reason investors like SaaS businesses. It’s also why getting this number right matters so much. If costs that belong in cost of revenue end up in general expenses instead, your gross margin looks better than it really is, and every KPI that uses it, like payback and LTV, is wrong too.

Expert Perspective | Certified QuickBooks ProAdvisor Your chart of accounts decides whether your KPIs can be trusted. If hosting, AI model fees, and support salaries are scattered across general expense accounts, there’s no reliable way to calculate gross margin, and payback and LTV inherit the error. Set up a clear cost of revenue section with separate accounts for hosting, cloud computing, model API fees, third party software embedded in the product, and support. Do the same for sales and marketing so CAC is easy to pull. It takes very little effort when you set it up early, and it saves a painful reclassification project right before due diligence, when every hour counts.

Cash and Efficiency KPIs

Growth and profit numbers only matter if you have the cash to keep going. These SaaS KPI metrics keep you honest about how long your money will last and how efficiently you’re using it.

Net burn rate

Net burn is how much cash you lose each month after money from customers comes in. The easiest way to find it is to compare your cash balance at the start and end of the month. If you started with $520,000 and ended with $480,000, your net burn was $40,000.

Use your bank balance or cash flow report for this, not your income statement. Annual prepayments can make a month look great in the bank even though your income statement barely changes, and the reverse can happen too. Burn is about cash, so measure it with cash. It’s also smart to look at a three month average, since one unusual month can throw off the picture.

Runway

Runway tells you how many months you can operate before running out of cash. Divide your cash balance by your monthly net burn. With $480,000 in the bank and $40,000 in monthly burn, you have 12 months of runway.

Update runway every month, and act early. Raising money usually takes longer than founders expect, often several months from first conversations to cash in the bank. Many founders aim to start fundraising or cutting costs with at least nine months of runway still left, so they aren’t negotiating from a position of panic.

Burn multiple

Burn multiple shows how much cash you’re burning to add each dollar of new ARR. Divide net burn by net new ARR for the same period. If you burned $120,000 this quarter and added $80,000 in net new ARR, your burn multiple is 1.5. You spent $1.50 for every new dollar of recurring revenue.

Lower is better. A rising burn multiple is an early warning that growth is getting more expensive, maybe because a marketing channel is wearing out or because churn is eating new revenue. It’s one of the most useful efficiency KPIs because it ties cash, growth, and retention together in a single number.

Rule of 40

The Rule of 40 says a healthy software company’s growth rate plus its profit margin should add up to at least 40 percent. A company growing 50 percent a year with a negative 10 percent margin hits exactly 40. So does one growing 15 percent with a 25 percent margin.

It’s mostly used for more mature companies, since early startups often grow fast while losing money on purpose. Still, it’s a helpful way to think about the tradeoff. If growth slows down, profit needs to go up to keep the business healthy, and the Rule of 40 makes that tradeoff easy to see.

Customer and Product KPIs

These SaaS KPI metrics don’t measure money directly, but they predict it. When they move, your financial KPIs usually follow a few months later.

Active users

Active users counts how many people actually use your product in a given period, often tracked as daily, weekly, or monthly active users. The key is defining “active” in a meaningful way. Logging in isn’t enough. For a project management tool, active might mean creating or updating a task. For a reporting tool, it might mean viewing a report.

Active users matter because they’re one of the best early warnings of churn. A customer who used your product daily and now uses it weekly is drifting away, even if they haven’t canceled yet. Watching active users by account, not just in total, helps you reach out before the cancellation email arrives.

Net Promoter Score

Net Promoter Score, or NPS, measures how likely customers are to recommend you. You ask one question, “How likely are you to recommend us to a friend or colleague?” on a scale of 0 to 10. People who answer 9 or 10 are promoters. People who answer 0 through 6 are detractors. Subtract the percentage of detractors from the percentage of promoters.

If 50 percent of responses are promoters and 15 percent are detractors, your NPS is 35. The number itself is less important than the comments people leave and how the score changes over time. A falling NPS often shows up before rising churn, which gives you time to fix the problem.

Support ticket volume and resolution time

Support ticket volume shows how often customers need help. Compare it to your number of customers so it doesn’t just rise because you’re growing. If you have 420 customers and get 84 tickets a month, that’s 0.2 tickets per customer. If that jumps to 0.35 after a product update, something in the update is confusing people.

Average resolution time shows how long it takes to fix a customer’s problem, from when the ticket is opened to when it’s closed. Slow resolution frustrates customers and can push them toward canceling. Together, these two KPIs tell you whether support costs are under control and whether customers are getting the help they need. And since support often counts as a cost of revenue, they affect your gross margin too.

Extra KPIs for AI Products

Most SaaS KPI metrics guides were written for traditional software. If your product runs on AI models, you need a few more, because your costs work differently.

With traditional software, serving one more customer costs almost nothing. With AI products, every request a user makes, like writing, summarizing, or generating an image, usually costs you money from an AI provider. Heavy users can cost far more to serve than light users paying the same price. That changes your gross margin and your payback math.

The most important extra KPI is cost to serve per customer. Tag your AI and computing costs by customer or account where you can, then divide each account’s costs by what that account pays you. You’ll quickly see which customers are profitable and which ones cost more than they bring in.

Next, track gross margin by plan, not just overall. Your overall margin might look fine while one plan, usually the unlimited or highest usage tier, is losing money on every customer. Finally, watch usage per active user over time. If usage climbs while prices stay flat, your margin is shrinking even if revenue looks healthy.

Here’s how much this matters. Using the earlier payback example, a customer paying $94 a month with an 80 percent margin pays back a $500 CAC in about 6.7 months. If AI costs push the margin down to 55 percent, that same customer brings in about $52 a month in profit, and payback stretches to about 9.6 months. Same customer, same price, very different business.

📌 From the Field An AI founder came to us believing her gross margin was around 82 percent, because that’s what her income statement showed. Her model API fees were sitting in a general software expense account instead of cost of revenue. Once we moved them, true gross margin dropped to about 58 percent. Worse, her unlimited plan was losing money on its top 15 users. She added a usage cap to that plan and created a higher tier for heavy users. Within two months, margin on the unlimited plan was positive again, and her payback period shortened by almost three months.

How to Choose the Right KPIs for Your Stage

You don’t need every KPI in this guide right away. Tracking too many numbers too early wastes time and spreads your attention thin. The right SaaS KPI metrics depend on where your company is today.

If you’re pre revenue or have just a handful of customers, focus on runway, active users, and trial conversion. You’re trying to prove people want your product and make sure you don’t run out of cash while you find out. Calculating LTV or burn multiple with ten customers gives you numbers that look precise but don’t mean much.

Once you have steady revenue, roughly up to $1 million in ARR, add MRR and its pieces, customer and revenue churn, CAC, gross margin, and burn. This is when the habit of tracking the same numbers every month starts to pay off, because you’ll have enough history to spot trends.

Past $1 million in ARR, efficiency KPIs take center stage. NRR, GRR, CAC payback, burn multiple, and the Rule of 40 are what investors look at when deciding whether your growth is healthy. At this stage, it’s also worth breaking KPIs down by plan, customer size, and marketing channel to see where growth is cheap and where it’s expensive.

Whatever your stage, aim for about eight to ten KPIs you review every month. If a number never changes a decision you make, drop it. If you keep wishing you had a number you don’t track, add it.

How to Set Targets That Actually Mean Something

SaaS KPI metrics without targets are just numbers on a screen. A KPI without a target is just a metric. But a target pulled out of thin air isn’t much better. Here’s how to set goals that help you make decisions instead of just making you feel bad.

Start with your own history. Look at the last six to twelve months for each KPI and find your average. Your first target should be a realistic improvement on that average, not a number you saw in someone else’s pitch deck. If your monthly churn has averaged 3.5 percent, a target of 3 percent next quarter is a meaningful goal. A target of 1 percent probably isn’t, at least not right away.

Next, compare against benchmarks from companies like yours. A company selling $50 a month plans to small businesses will have very different churn and payback than one selling $50,000 annual contracts to enterprises. The Aleph and Benchmarkit research linked earlier breaks its payback numbers down by contract size, which makes comparisons more fair.

Then connect each target to an action. A churn target should come with a plan, like improving onboarding or reaching out to accounts whose usage is dropping. A CAC target should come with a decision about which channels to grow or cut. Targets work best when everyone on the team knows what they’re supposed to do differently to hit them.

Finally, review targets every quarter. As the company changes, your goals should too. A KPI you once struggled with might become easy, and a new problem might deserve the spotlight.

Calculation Mistakes That Make KPIs Wrong

Even good founders end up with wrong numbers because of a few common calculation mistakes. Catching these early makes every KPI in your dashboard more trustworthy.

Mixing up time periods. If you calculate CAC using marketing spend from one month and new customers from another, the result is meaningless. Make sure the costs and the results in every formula cover the same period. For businesses with long sales cycles, some founders use spend from the prior month or quarter, but whatever you choose, keep it consistent.

Using the wrong starting number. Churn and retention should always be measured against the customers or revenue you had at the start of the period. If you divide by the ending number, new customers inflate the denominator and make churn look smaller than it really is.

Counting one time revenue as recurring. Setup fees, consulting projects, and unusual usage spikes make MRR and ARR look bigger and smoother than they are. Only count revenue you can actually expect again next month.

Treating Stripe totals as revenue. Stripe shows what you charged, not what you earned. If a customer pays $1,200 for a full year in January, Stripe shows $1,200 collected, but you’ve only earned $100 that month. The rest is deferred revenue, which moves into earned revenue month by month under the accounting standard ASC 606. Using Stripe totals as revenue makes KPIs like gross margin and the Rule of 40 wrong.

Rounding away problems. A monthly churn rate of 2.6 percent and 3.4 percent can both round to “about 3 percent,” but over a year they lead to very different results. Keep at least one decimal place for KPIs that compound over time, like churn and retention.

Turning KPIs Into a Monthly Habit

Tracking KPIs only helps if you look at them regularly and act on what you see. The founders who get the most out of their numbers follow a simple monthly routine once their books are closed.

Start with cash. Check your bank balance, calculate net burn, and update runway. If runway dropped by more than a month, find out why before anything else.

Then review growth. Look at MRR and its four pieces, ARR, and average revenue per account. Compare each to last month and to your three month average. For any number that moved a lot, write down the reason.

Next, check retention and unit economics. Review churn, NRR, GRR, CAC, payback, and gross margin. If you run an AI product, check margin by plan and cost to serve for your heaviest users.

After that, look at the leading indicators. Active users, trial conversion, NPS, and support volume often warn you about problems before they show up in revenue.

Finish by writing three short notes. What went well, what worries you, and what you’ll do differently next month. Share them with your cofounder, team, or investors. Over a year, those notes become a clear record of how your business changed and why.

📌 From the Field A founder we started working with had KPIs scattered across four spreadsheets, each calculated a little differently. Her churn number changed depending on which file she opened. We set up one monthly KPI sheet pulled from her closed books and Stripe, with written definitions at the top. Three months later, she spotted a jump in support tickets after a product release before it turned into cancellations. She fixed the confusing feature, and churn that quarter stayed flat instead of spiking. Having one trusted set of numbers is what let her see it in time.

The Bottom Line

The best SaaS KPI metrics aren’t the most complicated ones. They’re the ones you calculate the same way every month, compare against realistic targets, and use to make real decisions. Start with the KPIs that fit your stage, make sure your books and your billing data agree, and add more only when you need them.

Revenue KPIs tell you if you’re growing. Retention KPIs tell you if customers stay. Unit economics tell you if growth is worth it. Cash KPIs tell you how long you can keep going. And customer KPIs warn you about problems before they hit revenue. When all five are clear, you stop guessing and start running your company with confidence.

Frequently Asked Questions about SaaS Accounting

What’s the difference between leading and lagging SaaS KPI metrics?

Leading KPIs give you an early warning. They move before revenue does, so they show you what’s likely to happen next. Active users, trial conversion, Net Promoter Score, and support ticket volume are all leading KPIs. If active users start dropping this month, cancellations usually follow a month or two later.

Lagging KPIs show what already happened. MRR, ARR, churn, and net revenue retention are lagging, because by the time they move, the customer has already upgraded, downgraded, or left. They’re the numbers investors focus on, but they can’t warn you ahead of time.

You need both. Leading KPIs give you time to fix problems. Lagging KPIs tell you whether your fixes worked.

How many KPIs should a SaaS startup track?

About eight to ten, reviewed every month. If you’re very early, five or six is plenty. A number that never changes a decision you make doesn’t need to be on your list.

What’s a good churn rate for a SaaS company?

It depends heavily on who you sell to. Companies selling low priced monthly plans to small businesses usually see much higher churn than companies selling annual contracts to large enterprises. Small businesses open and close more often, and monthly plans are easier to cancel than a signed yearly contract. That’s why one universal number doesn’t help much.

A better approach is to watch your own trend. If monthly churn is falling quarter after quarter, you’re moving in the right direction, even if the number is higher than someone else’s. Look at customer churn and revenue churn together, too. Losing a handful of small accounts matters a lot less if your larger customers are staying and spending more.

When churn does rise, look for the pattern behind it. Are cancellations coming from one plan, one marketing channel, or customers who signed up in the same month? Finding the common thread is usually faster than guessing, and a few short exit surveys can tell you the reason behind it.

Should KPIs come from Stripe or from my accounting software?

Both, depending on the KPI. Subscription numbers like MRR, churn, and trial conversion usually come from Stripe or a tool connected to it. Financial numbers like gross margin, burn, and runway should come from your accounting books and your bank. Line the two up every month so you can explain any difference, like annual prepayments that Stripe shows as collected but your books spread across twelve months.

Some KPIs need both sources at once. CAC payback, for example, uses new customer revenue from Stripe and gross margin from your books. Lifetime value works the same way. If either source is off, the KPI is off too. That’s why closing your books every month matters so much. It’s the step that makes sure the accounting side of every combined KPI is accurate before you share it with anyone.

Do I need special software to track SaaS KPIs?

Not at first. A well organized spreadsheet that pulls from Stripe and your accounting software covers most KPIs for an early company. Write the formula for each KPI at the top of the sheet so everyone calculates it the same way.

As you grow, tools like ChartMogul or Baremetrics can automate subscription KPIs, build cohort charts, and create reports for investor updates. They save hours once you have hundreds of customers. Just remember that any tool is only as accurate as the data behind it. If your books are messy, a polished dashboard just shows the wrong numbers more clearly.
