What should a small business spend on bookkeeping as a percentage of revenue?

A common benchmark is one to three percent of gross revenue for total bookkeeping and financial administration, with a rough midpoint around two percent. Bookkeeping on its own tends to sit lower. But the number worth remembering is not the percentage; it is the caveat. Revenue is a sanity check, not a target. What actually drives the cost is transaction volume, scope of services and complexity, so two businesses with identical revenue can reasonably spend very different amounts. This page gives the benchmark by revenue tier, explains what really moves the cost, and shows how to use the percentage without being misled by it.

The benchmark by revenue tier

As a general market guide, spend as a share of revenue falls as the business grows, because bookkeeping carries a baseline cost that a larger business spreads over more revenue. These are common ranges, in US dollars, and a starting point rather than a rule.

A worked example makes the midpoint concrete: a business with five hundred thousand dollars of revenue spending two percent would spend about ten thousand dollars a year, or roughly eight hundred and thirty dollars a month, for ongoing bookkeeping, software and basic tax preparation. That figure is a reasonable middle of the range, not a number to hold every business to.

Why the percentage misleads, and what actually drives the cost

Revenue does not decide how much bookkeeping work there is. Four things do, and they are what a sensible budget should be built on.

This is why the percentage is a sanity check, not a target. If your spend lands far outside the range for your size, it is worth asking why, but a business with high volume or real complexity can spend above the benchmark and be right to, while a simple high-revenue business can spend well below it. Budget from the work, then use the percentage to check the answer.

What comparable businesses actually spend

Editor's note, to complete before publish: this section is where Numetix replaces the generic benchmark above with its own observed figures, what businesses like the reader's actually spend, which is the part a general article cannot offer. The table below is a placeholder. Fill it with real spend-as-a-share-of-revenue data from the Numetix client base, ideally split by revenue tier and by vertical (law firms, medical and dental practices, property management, nonprofits). Do not publish the placeholder values.

Where Numetix fits

A benchmark answers what businesses in general spend. What a specific business should spend depends on its volume and complexity, which is exactly what a specialist can scope accurately rather than guess. Numetix prices on the actual work, transaction volume and the scope your industry requires, rather than a blunt share of revenue, and because it specializes in four industries with known complexity, it can tell you where a business like yours usually lands. If your current spend is far from the benchmark for your size, that is worth a conversation; the percentage is where the question starts, not where it ends.

This page is general information, not accounting or financial advice. The benchmark ranges here are common market guidelines that shift over time and vary by provider and region; they are not a quote. What a specific business should spend depends on its volume, scope and complexity. Numetix provides bookkeeping and reporting priced on the work involved.
