ARR is up. Cash burn is too.
Your monthly recurring revenue is climbing. Net retention is solid. Sales pipeline looks healthy. And your tax bill is growing faster than revenue, your services arm is bleeding margin, and the OBBBA / Section 174 changes have your CFO and CPA giving you contradictory advice. That’s not a sales problem. It’s the same financial pattern I see in every SaaS company that scales without a financial operating system underneath the engineering org — service‑line P&L blended into uselessness, R&D cost mapping nobody documents, and tax exposure compounding every quarter.
For US‑based SaaS companies doing $1M–$20M in revenue, particularly those with services arms (implementation, professional services, customer success).

Trusted by growing service businesses
I run 60/15/15. Here’s how it applies to SaaS specifically.
If you’ve read SaaS finance content before — Bessemer, OpenView, SaaStr — you know the dominant framework is the Rule of 40 (growth rate + profit margin ≥ 40%) layered on top of unit economics (LTV:CAC, NRR, CAC payback). That framework works for understanding venture‑stage SaaS. It doesn’t tell you where your operating leak actually is.
For SaaS that means post‑COGS margin including hosting, third‑party APIs, customer success at delivery layer, and any services revenue blended in. Pure‑play software‑only GM should hit 75–80%. Most SaaS companies I look at run 55–65% blended once their services arm and customer success cost are properly classified.
Controversial for venture‑stage SaaS where 30–50% S&M is celebrated. The framework target applies to companies pursuing profitable, sustainable growth rather than burn‑driven hypergrowth. If you’re VC‑backed and in growth mode, the framework runs differently. If you’re bootstrapped, profitable, or post‑Series A and looking at the path to profitability, 15% S&M is the destination — not the starting line.
Engineering and product cost lives in COGS or a separate R&D line, not G&A. G&A is leadership comp, finance, HR, legal, office. Most SaaS companies run 10–15% here once classified properly.
CAC payback, NRR, and Rule of 40 still matter for growth decisions. 60/15/15 tells you whether your operating economics are built to compound profitably as you scale — or whether you’re funding losses with venture capital. Top quartile SaaS companies hit 25–35% operating margin at scale. Most don’t, and the gap is closeable.
Section 174 capitalized $300K of your engineering spend. Your effective tax rate doubled. Nobody told you about the R&D credit that offsets it.
A $5M SaaS company is potentially leaving $150K–$400K per year on the table between credit capture, election timing, and state conformity. That’s before any operational leak. Three things are compounding right now — Section 174 capitalization, the OBBBA transition, and R&D credits unclaimed under Section 41 and at the state level.
A $5M SaaS company at industry‑standard tax positioning keeps maybe $400K–$800K of EBITDA. The same company with proper R&D credit capture, Section 174 election strategy, and state conformity work keeps $600K–$1.2M. Same product. Same customers. Same engineering team. The framework that closes the gap has three steps in a fixed order: COGS first, S&M second, G&A third. Never reordered. For SaaS, the COGS leak is real and the tax leak is bigger.
Engineering spend you can’t deduct in full
A SaaS company spending $1M on engineering used to deduct $1M. Under Section 174 you deducted $200K in year one. Even profitable SaaS companies suddenly looked like they had taxable income they didn’t actually have.
New rules, old amortization still in motion
Mid‑2025 OBBBA restored immediate expensing for domestic R&E for tax years beginning after December 31, 2024 — but kept 15‑year amortization for foreign R&E. Most founders haven’t had this conversation with their CPA yet.
Federal + state credits leaving the door
Section 41 federal credits worth 6–8% of qualified spend, refundable up to $500K against payroll tax for qualifying small businesses. State‑level credits another 10–25%. Combined: $200K–$400K per year difference, every year.
The leak in three figures.
Four numbers. Running alongside Rule of 40, not replacing it.
For SaaS, 60/15/15 means 60% blended gross margin (75–80% on pure software, 30–50% on services), 15% sales & marketing toward sustainable growth, 15% G&A with engineering parked in COGS or a separate R&D line, and 30% operating margin — where top‑quartile SaaS companies live at scale. CAC payback, NRR, and Rule of 40 still drive growth decisions. 60/15/15 tells you whether the operating economics underneath them compound profitably.
In SaaS, COGS is where you bleed first — and it’s where you fix it first.
Most SaaS founders think their cost problem is engineering payroll or hosting. It usually isn’t. Healthy SaaS gross margin for a company at $1M–$20M is 60% blended (75–80% on pure software, 30–50% on services). Most run 50–60% blended because services drag the average. The leak shows up in three places.
Services revenue priced on cost‑plus instead of value
Most SaaS implementation and professional services teams price work on cost‑plus: engineer time, add a markup, that’s the bill rate. The result is services running at 30–40% GM because the markup never recovers fully‑loaded burden, slipped timelines, or scope creep. Top SaaS companies separate services into growth services (driving expansion and retention, sometimes at near‑zero margin) and revenue services (50%+ GM standalone). A typical $5M SaaS company with 25% services revenue can lift blended GM 4–7 points by this restructure alone.
Customer success cost classified wrong
Customer success teams are often classified as G&A or S&M when in reality their cost is delivery cost — they’re servicing the existing customer base to maintain the recurring revenue. That’s COGS. A $5M SaaS company with $400K of CS cost classified as G&A is showing 78% GM when the real number is 70%. The fix: split CS into proactive expansion (S&M) and reactive support / retention (COGS). Most companies have a 60/40 or 70/30 split that maps cleanly.
Engineering cost mapping nobody does for tax purposes
The biggest leak isn’t operational — it’s tax. R&D cost mapping tags engineering spend by project, by activity type, and by qualifying‑versus‑non‑qualifying for R&D tax credit purposes. Almost every sprint at a SaaS company contains qualifying R&D activity. With proper mapping from day one, a $5M SaaS company spending $1.5M on engineering typically captures $90K–$150K in federal credits plus $30K–$80K in state credits annually — plus the ability to optimize Section 174 and 280C elections.
Most SaaS founders are running three jobs at once.
If you took 90 days off — no calls, no emails, no decisions — what happens? In most SaaS companies I look at, three things break: the largest enterprise relationships call asking for the founder specifically because the relationship is with you, not the company. Strategic product decisions stall because you’re the senior product voice. Investor and board conversations grind because you’re the one who runs the financial story.
That’s not a SaaS company. It’s a venture‑backed product with a charismatic founder. Companies like this sell at depressed multiples in down markets — buyers worry about retention if the founder leaves. SaaS companies that run independently with documented product roadmaps, delegated enterprise relationships, and a leadership team that closes without the founder sell at premium multiples to strategic acquirers and PE rollups. Same ARR, same NRR, same growth rate. Different multiple. On a SaaS company at $5M ARR doing $1M EBITDA, that’s the difference between a 4x revenue exit and an 8–12x revenue exit. $20M to $40–60M of total enterprise value.
The fix is what I call “firing yourself” — not retiring, but building the company so it doesn’t depend on you in three places at once: senior product, senior salesperson, and financial story. It’s a 12–18 month process and it’s the single biggest enterprise value lever any SaaS company has. For SaaS specifically, this is also what unlocks the R&D documentation discipline — when senior engineers own project documentation instead of waiting for the founder to dictate it, the tax credit work becomes part of the operating cadence instead of a year‑end scramble.
This is also why “we just need more ARR” is the wrong frame. Bigger numbers in a more dependent company don’t move the multiple. They just make the eventual fundraise or sale harder.

What this looks like in real businesses.
“$402,838 tax liability turned into an $80,000 refund.”
“$0 to ~$300K MRR with an embedded fractional CFO from day one.”
“$402K tax bill eliminated — refunds at federal and state level.”
Same ARR. Same NRR. Same growth rate. Different multiple.
Most SaaS companies sell at 4–8x ARR. High‑quality companies command 10–15x. The single biggest non‑metric lever is reducing dependence on the founder. Documented product roadmaps, delegated enterprise relationships, and a financial operating system that runs without you compound into a higher multiple at exit.
On a SaaS company at $5M ARR doing $1M EBITDA, that’s the difference between a 4x revenue exit and an 8–12x revenue exit. $20M to $40–60M of total enterprise value. Bigger ARR numbers in a more dependent company don’t move the multiple. They just make the eventual fundraise or sale harder.
The fix is “firing yourself” in three roles at once: senior product, senior salesperson, and financial story. A 12–18 month process. The single biggest enterprise value lever any SaaS company has — and the one that unlocks the R&D documentation discipline alongside it.
