The SaaS CFO's FinanceTech Stack Report 2025 - Ben Murray's Top Takeaways

Last updated: November 202658 min watch

  • Ben Murray, Founder, The SaaS CFO

  • Kirk Kappelhoff, Senior Director of Strategic Finance, Drivetrain

Every year, Ben Murray, The SaaS CFO, asks finance and accounting leaders at SaaS companies which software they use, from accounting and billing to FP&A and sales tax. He started the survey after founders and CFOs kept asking him what to buy, and he wanted to give them an answer backed by real data.

The 2025 edition of his Finance Tech Stack Report, his sixth, drew more than 600 responses, mostly from CFOs, controllers, and finance directors. Ben breaks the results down by company size, measured in annual recurring revenue (ARR), to show how a finance stack changes as a company grows and when teams replace spreadsheets with dedicated software.

Company size is only one of the signals Ben uses to time a purchase. Whether a company needs a dedicated tool often depends on how complicated its invoicing is, whether it has private equity or venture capital owners, and whether it’s preparing for an audit or due diligence review.

When Ben joined Kirk Kappelhoff, Sr. Director of Strategic Finance at Drivetrain for a webinar to share his results, he said finance and accounting teams were typically using 12–16 different tools.

This article covers that conversation, including a walk-through of the report’s main software categories Ben tracks each year, his advice on where he would start with a fixed tool budget, and when a tool in a given category becomes a must-have for SaaS businesses.

Plan the ERP move while the data is still small

Ben advised planning the move from QuickBooks or Xero to an ERP before $10M ARR, because the more data a company has, the harder the migration gets. His survey showed QuickBooks as the leading vendor with companies in the lower ARR bands and Sage and NetSuite taking over at roughly $10–11M.

Ben said he’s run migrations from Microsoft Dynamics and QuickBooks into full ERPs and described each one as a significant data-transformation exercise. He said companies at $5–10M ARR that have a clear path to $15–30M should decide at that point whether to stay with QuickBooks using bolted-on point solutions or move to Sage or NetSuite.

Ben said that for years, his annual reports, including his fifth annual tech stack report from the previous year, showed QuickBooks, Xero, Sage, and NetSuite had led in the accounting category. However, in the 2025 report, his data showed QuickBooks and Xero starting to lose share, and two new AI-native tools appeared: Rillet, built for SaaS accounting, and the more industry-agnostic Campfire.

So accounting, a space you'd think is sleepy and unsexy, is actually seeing real new entrants.

Buy invoicing tools on complexity and start RevRec at $3–5M ARR

Ben treated invoicing and RevRec as separate decisions. Invoicing software depends on how many invoices a company sends and how complex they are, while RevRec depends on company size, starting at $3–5M ARR. The two often end up in the same product, because subscription management platforms such as Maxio handle both recurring billing and revenue recognition.

Kirk asked Ben how he would split a fixed budget across the finance tool categories. On the accounting side, Ben said invoicing and RevRec get the real investment, whether through an ERP or a separate tool, and he added that FP&A software needs a real budget too. He had seen founders balk at a $20,000–30,000 quote for subscription management, invoicing, and RevRec together. His answer was that a recurring-revenue business needs RevRec that is bulletproof and defensible, and that the return shows up down the road even when it isn’t obvious upfront.

Move invoicing into software when complexity outgrows your accounting tool

Kirk asked whether a company should move to dedicated invoicing software once it reaches a set number of invoices per accountant or a certain ARR. Ben said the decision depends on how many invoices a company sends and how complicated they are.

A company sending 50 enterprise invoices a year, each billed annually, can stay in QuickBooks. Billing gets complicated once usage-based charges, several revenue streams, a mix of annual and monthly contracts, and renewals come into play. Ben said QuickBooks’ built-in features couldn’t handle that complexity, especially renewals and subscription management, so the work becomes manual. He said a company at that stage needs either a point solution for invoicing, such as Stripe, Maxio, or Chargebee, or a full ERP.

He said he’s also seen companies already on Sage or NetSuite add a dedicated invoicing tool because it did one job, such as usage-based billing, especially well.

Ten enterprise invoices a month, no big deal. A hundred invoices, with renewals, expansions, and contract mods layered in, and now you need real technology rather than just adding headcount to your accounting team.

Start accrual accounting and RevRec at $3–5M ARR

Ben recommended that companies take full accrual accounting and revenue recognition seriously at $3–5M ARR, the stage at which there’s enough data volume to need true economics on an accrual basis. His example was a company whose annual invoicing all lands in January, which leaves February empty on a cash basis and distorts the revenue figures that feed its SaaS metrics.

In the 2025 report, spreadsheets were the most common way respondents handled RevRec. Ben said that’s typical: Teams start revenue recognition in a spreadsheet and move to a dedicated tool later. He added that some respondents answered N/A, meaning they had no RevRec tool or process at all.

Ben said RevRec follows a pattern he saw in most of his categories, including FP&A, close management, and sales commissions. Teams build a basic process in a spreadsheet first, then move it into software, usually once audit or due diligence pressure arrives. His advice was not to stay in the spreadsheet longer than you need to.

Plan on investing in FP&A software at $10M ARR (or earlier)

Ben called FP&A software a must-have above $10M ARR. Companies between $5M and $10M may need it sooner if they have PE or VC owners, because those investors expect accurate forecasts and reliable metrics. Those demands ramp up after a PE acquisition, and Ben said doing that reporting and analysis in spreadsheets wears a team down. He saw the same expectations from boards at some companies under $10M.

Ben knew the difference firsthand. As director of finance at a billion-dollar regional airline, he had to forecast from a web of connected spreadsheets that took forever to update, until the team moved to an FP&A solution. He called it a night-and-day difference, and said even pulling actuals into an FP&A tool makes life dramatically easier.

Settle your metric definitions before you buy a metrics tool

With his fractional clients, Ben built each SaaS metric from raw data in a spreadsheet and calculated it by hand to settle the methodology, such as whether to measure it over a trailing three, six, or twelve months. Once he was confident the numbers were right, he chose software to replicate the process.

Kirk used customer acquisition cost (CAC) to show why a tool’s calculation method matters. CAC divides sales and marketing spend by the number of new customers, which raises the question of which quarter’s spend to count. Many companies divide a quarter’s spend by the customers won in that same quarter. If it typically takes 90 days to turn a prospect into a customer, this quarter’s new customers came from last quarter’s spend, so matching them to this quarter’s spend misstates CAC. Kirk noted that no GAAP standard says which approach is right for CAC or other SaaS metrics, so each company has to decide.

A metrics tool makes that decision for you, and Ben found that many tools didn’t show how they had made it, which is why he recommends checking the calculations before choosing a software.

A lot of tools are frankly a black box in how they calculate things.
Ben MurrayFounder, The SaaS CFO

When this webinar was recorded, the options for metrics tools varied widely. Ben noted that spreadsheets, BI tools, ERPs, FP&A platforms like Drivetrain, and subscription management tools all claimed to report SaaS metrics, but they did different jobs. For example, some tools covered revenue-side metrics, but nothing on the expense side.

Ben called the market at the time the Wild West of reporting and said the first question to ask is what you expect the tool to do: calculate your metrics, or just present numbers you have already calculated in a spreadsheet.

When an attendee commented in the chat that net revenue retention (NRR) is “whatever the CEO wants it to be,” Ben disagreed. He said a company can get away with loose definitions internally for only so long. Once investors or a due diligence team look at the numbers, the inconsistency gets caught.

He’d seen this play out at a company he worked with that wanted customers who signed up during a three-month trial counted as new, but didn’t want customers who left during the same trial counted as churn. Ben told them they couldn’t have it both ways: “If you count the plus-one, the reversal has to be a negative-one.” The company resisted, but the cash told the real story and the problem surfaced anyway. As Ben put it, “Wild West, but someone always catches it.”

Look past ARR to decide on sales tax, close management, and commissions software

Ben gave no ARR threshold for these three categories, and he still listed sales tax coverage and sales comp among his core finance tools, alongside an ERP, invoicing, subscription management, and RevRec. The triggers are outsiders, such as a state or a buyer's diligence team, and complexity that a spreadsheet can no longer track.

Handle sales tax before a state asks

Ben said state taxing jurisdictions have become much better at detecting sales tax nexus, and that investors and acquirers check sales tax during due diligence reviews. They will ask companies to justify why they were or weren't remitting sales and use tax, or VAT in Europe. He described the worst case as a state asking how long you've been doing business there and finding five years of undisclosed nexus.

Ben advised setting up sales tax software early, adding that once it’s integrated with your ERP or accounting system, it largely runs itself.

Formalize the close once the team can't track who does what

Ben's test for whether it’s time to invest in formal close management software wasn’t based on an ARR threshold. Rather, it’s whether the team can still track who does what. Formal close management means writing down every step of the month-end close and who is responsible for each one.

At the time, many survey respondents answered N/A for this category, meaning they had no close management tool or process. That surprised Ben, because he believed a company needs formal close management once it reaches a certain size. He said even a spreadsheet checklist can improve quality control, for instance by making sure no one forgets to reconcile deferred revenue.

He named FloQast and BlackLine as purpose-built close tools and said some ERPs, including Sage and Campfire, offered close management natively.

Move sales comp out of spreadsheets as plans multiply

Sales comp spreadsheets break as reps come and go, plans change from year to year, and people on legacy plans keep getting paid under them. Ben called sales comp a category that stays nice to have until you realize it's a must-have. The category covers commissions and other variable pay for anyone on revenue-driven comp, typically excluding executive bonuses. Ben named Salesforce, which acquired Spiff, and QuotaPath, which he said also helped with comp plan design, and described tools that connected to the CRM, took in bookings data, and calculated payouts automatically.

Make FP&A software the layer that connects the stack

Ben urged controllers, CFOs, and FP&A leaders not to bolt on one tool after another as problems come up. He told them it’s important to understand and plan how every tool fits together, saying that CFOs in particular need a seat at the table when the company makes decisions about its data architecture.

He suggested treating his report as an internal product roadmap for that plan.

Ben said FP&A software is usually at the center of that plan because FP&A teams need HR, financial, and bookings data in one place to do their work. Kirk agreed. He said teams bring historical data together from the ERP, CRM, and HR system so they can forecast on top of it, adding that data consolidation can happen in the FP&A tool or sometimes in a data warehouse such as Snowflake or Azure.

Once that data sits in the FP&A platform, it can handle reporting too. Ben said FP&A platforms were increasingly becoming the analytics layer, and added that he prefers running analytics there to maintaining a separate Power BI project.

Kirk explained that while BI software houses and visualizes historical data, Drivetrain’s SaaS financial planning software brings in actuals from source systems, forecasts on top of them, and reports on the forecast all in one place, for example, showing total ARR against plan, ARR by market segment, and ARR under high, base, and low scenarios.

The data also has to fit the way the company tracks its numbers. Kirk said Drivetrain’s AI-generated models adapt to however a company organizes its chart of accounts, whether it tags transactions by department or location or nests accounts several levels deep, and keeps that structure intact.

If you’re ready for FP&A software and want one platform that also connects your ERP, CRM, and HR data, reports on SaaS metrics, and runs BI-style analysis on your forecast, book a demo with Drivetrain.

Summary

  • Must-have finance software covers six functions: accounting, invoicing, subscription management, revenue recognition (RevRec), sales commissions, and sales tax.
  • An ERP, such as Sage or NetSuite, typically replaces QuickBooks or Xero at around $10M ARR. Ben recommended planning the move at $5–10M ARR if the company has a clear path past $15M.
  • FP&A software becomes a must-have above $10M ARR, or sooner for companies with private equity (PE) or venture capital (VC) owners or a board with high expectations for forecasting.
  • Business intelligence (BI) and analytics software, such as Power BI, handles historical data. Ben said he prefers running analytics inside the FP&A platform.
  • Invoicing software becomes necessary when invoice volume and complexity, such as renewals and contract changes, outgrow the accounting system.
  • RevRec software becomes necessary at $3–5M ARR, when a company needs accrual accounting to spread annual contract revenue across the months it covers.
  • SaaS metrics software should come after you’ve settled how to calculate each metric. Ben found many tools opaque about their calculation methods. So, he said to make sure the tool you’re considering can reproduce yours.
  • Close management software becomes a must-have once the team can’t track who does what.
  • Sales tax software should be in place before a state, investor, or acquirer asks whether you owe tax there.
  • Sales commission software becomes necessary once reps are paid under several plans, including old plans that still pay out.
  • Plan how each new tool will connect to your existing stack before you buy it. Ben said he sees FP&A software as the usual hub for ERP, CRM, and HR data.

Questions from the webinar

We’re a small startup on QuickBooks. Should we move to Sage first and then NetSuite, or go straight to NetSuite?

Choose one ERP and move once. Sage and NetSuite are both full ERPs, so neither works as a stepping stone to the other, and a point solution can extend QuickBooks’ runway if you aren’t ready for either.

How should a CFO set a budget for a new finance tool?

Set the budget by the complexity the tool has to handle, because complexity drives both cost and implementation effort. A self-serve tool can suit a founder-led business, while a CFO’s tool is priced by team size and seats. In a webinar hosted by Drivetrain, The SaaS CFO, Ben Murray, put the range at about $100 a month to $50,000 a year or more, with $20,000–50,000 or more typical for a CFO-grade tool.

Should a CFO hire an expert or buy software to run finance operations?

Buy the software, and bring in an expert where setup is complex. Sales commission plan design and revenue recognition are two areas where outside expertise helps at setup, while the day-to-day work still runs on software. Finance and accounting can’t scale without technology, so the work lies in balancing headcount and tooling.

Can you standardize a SaaS P&L across entities on different charts of accounts?

Yes. Get each entity’s chart of accounts right, then map those charts of accounts into a single FP&A model and report the SaaS P&L there, since accounting software has generally been weak at board-level reporting. Ben Murray, The SaaS CFO, described this setup in a webinar hosted by Drivetrain, saying that once the mapping is done, “I’m literally just hitting refresh and my SaaS P&L updates.”

Will newer all-in-one ERPs replace finance point solutions?

Not necessarily. An all-in-one ERP replaces point solutions only when a finance team values one system over the depth of specialized tools. In his sixth annual finance tech stack report survey, The SaaS CFO, Ben Murray, said that best-of-breed point solutions have won that trade-off every year leading up to and including this most recent report. However, he noted the preference is easier to state than to act on. When he shared his survey results with Drivetrain in a 2025 webinar, he said Campfire and Rillet, Rillet especially, were building toward one-stop shops with RevRec, invoicing, and integrations to tools such as Anrok.

Do Power BI and Drivetrain compete?

No. Speaking with Ben Murray, The SaaS CFO, in a 2025 webinar, Drivetrain’s Senior Director of Strategic Finance, Kirk Kappelhoff, explained that Power BI and similar BI tools house and visualize historical data, while Drivetrain is an FP&A software that brings in actuals, forecasts on top of them, and analyzes the forecast. He added that Drivetrain integrates with Power BI and that most of Drivetrain’s Power BI users connect the two.
