The quote lands in your inbox: $2,400 a month for bookkeeping, payroll, and a monthly close. You have no idea if that is high, low, or normal. Nobody publishes real numbers, every founder you ask has a different setup, and the pricing pages all say “let’s chat.” So you do what most founders do: pick the cheapest option that looks credible, then find out what it really cost a year later, in cleanup fees and a diligence scramble.
Here is the anchor nobody gave you: budget 2 to 4 percent of revenue for your entire finance function, and buy it in layers, not people. Spend below that and you are usually not saving money, you are deferring cost. Spend it all on one full-time generalist and you are overpaying for half the stack while missing the other half.
The 2 to 4 percent rule, translated by stage
Percent-of-revenue guidance is useless without stage context, so translate it:
- Pre-revenue and Seed: expect roughly $1,000 to $5,000 a month for outsourced bookkeeping plus fractional strategic guidance. At this stage you are buying clean records, compliance, and someone who can tell you your burn without building a spreadsheet first.
- $1M to $5M in revenue: expect $60,000 to $150,000 a year. Complexity drives the increase more than revenue does: more people, more contracts, deferred revenue schedules, and investor reporting that has to hold up in diligence.
- $5M to $10M and beyond: expect $200,000 or more, usually a hybrid of in-house hires and outsourced specialists.
Quick math: at $2M ARR, 2 to 4 percent works out to $40,000 to $80,000 a year for the whole function, bookkeeping through CFO-level guidance. Spend toward the top of the range when you are raising or restructuring. Spend less when your model is stable. Below about $2M in revenue, treat 2 to 4 percent as a ceiling check, not a budget. Fixed costs set a floor: a real close, payroll, and compliance run $1,000 to $5,000 a month no matter what your revenue is.
What that budget buys: five layers, not one person
“How much does an accountant cost” is the wrong question, because a scaling startup’s finance function is a stack, and each layer is a different skill at a different price.
- Bookkeeping. Every transaction recorded and reconciled, the month closed within 5-10 business days, and a chart of accounts built for how tech startups actually earn revenue now. The pure-SaaS subscription model is no longer the default: AI-native companies mix usage-based pricing, credits, and hybrid contracts, and each of those creates its own deferred revenue and recognition complexity. The label changed; the bookkeeping problem got harder. Unreliable KPIs and messy diligence both start with weak bookkeeping, which is why this layer is non-negotiable.
- AR and AP. Money in, money out. On the receivables side, invoices go out promptly and follow-up happens on a schedule, not when someone remembers. On the payables side, bills get approved and paid on a fixed cadence. When nobody owns this layer, cash leaks quietly in both directions.
- Controller-level review. The layer that turns accurate books into decision-ready numbers: annual budget preparation, then P&L, balance sheet, and cash flow with variance against that budget, plus burn and runway tied to source data. Without it, you have records, not information.
- CFO-level guidance. Scenario models, fundraising assumptions you can defend, and board reporting that connects metrics to decisions. Before Series B, most teams do not need to add a full-time CFO salary to get that work done cleanly and stay compliant. Buy the judgment, not the headcount.
- Payroll and people ops. A consistent payroll cadence, T4s filed correctly, and CRA remittances on time. Payroll penalties are the most avoidable expensive mistake in the stack, and directors remain personally liable for unremitted payroll taxes.
The $120,000 mistake
The most common overspend is not a pricey firm. It is hiring one mid-level, do-everything finance person at roughly $120,000 who is overqualified for the bookkeeping, underqualified for the CFO work, and unreviewed in between. You pay a full salary for partial coverage of the stack, and when that person leaves, the whole function walks out the door with them. Buying layers instead means each layer is handled by someone who does exactly that work all day, and continuity does not depend on one resignation.
Three signals you are underspending
Under-buying finance looks fine right up until it doesn’t. Check for these:
- Your close finishes mid-month, or there is no fixed close date at all. Every decision you make in the meantime runs on stale numbers, and without a consistent cadence you can’t even say how stale.
- You cannot state your runway on demand. If the number only exists when someone builds it, you do not have a finance function, you have a reporting request queue.
- Deferred revenue is a year-end problem. Whether you sell subscriptions, usage, or both, “we’ll fix deferred revenue at year-end” is the sentence diligence teams get paid to find.
Any one of these costs more to fix later than the budget gap that caused it. Price the function against the 2 to 4 percent anchor, buy it in layers, and treat the spend as what it is: the cost of decision-ready numbers, not overhead.
