Bookkeeping Industry Benchmarks
The “1x revenue” rule everyone repeats is for tax-and-compliance practices. Bookkeeping firms trade on different math. Here are the real multiples, what changes them, and why an advisory-heavy book is worth more than a compliance-heavy one of the same size.
Three multiples come up in every bookkeeping firm sale. SDE (seller’s discretionary earnings) is most common for small owner-operated firms, because it adds the owner’s salary and perks back into the earnings. EBITDA is standard once a firm is large enough to run without the owner in the seat. Revenue multiples are the quick gut-check but ignore profitability, so buyers use them only to triangulate.
The table below sets the baseline ranges for bookkeeping firms specifically, then the second table shows how size and service mix move you within those ranges.
Baseline valuation multiples for a bookkeeping firm
| Multiple type | Typical range | When buyers use it |
|---|---|---|
| SDE multiple | 2.5x–3.3x | Small, owner-operated firms |
| EBITDA multiple | 3.5x–4.6x | Mid-size firms that run without the owner |
| Revenue multiple | 1.0x–1.2x | Quick estimate / sanity check only |
Worked example: a firm with $310,000 in EBITDA at a 4.0x multiple is worth roughly $1.24M. The same firm valued on a 1.1x revenue multiple against $900,000 in revenue lands near $990,000. The spread between those two numbers is exactly why buyers anchor on earnings, not revenue, and why your add-back discipline matters at sale.
What moves you within the range
| Factor | Pulls multiple | Why |
|---|---|---|
| Advisory / CAS-heavy mix | Higher | Stickier clients, higher margin, less price-shopped |
| Compliance-only mix | Lower | Commoditized, more substitutable, thinner margin |
| High recurring revenue (40%+) | Higher | Predictable income survives the ownership change |
| Project / one-off heavy | Lower | Revenue resets each period, harder to underwrite |
| Low client concentration | Higher | No single client can sink the book post-sale |
| Top clients owner-dependent | Lower | Relationships may walk when the owner does |
| Documented systems & SOPs | Higher | Transfers cleanly to a new owner |
| Clean, normalized financials | Higher | Buyer can finance the deal with confidence |
The market backdrop
Sale prices have been rising. The median accounting and tax practice sold for around $500,000 in 2025, a 25% gain over the prior five-year period, with the average earnings multiple landing near 2.3x and revenue near 1.1x. Demand from buyers is strong, helped by a wave of retiring practice owners and a shrinking pipeline of new ones, which puts well-run, transferable firms in a good negotiating position.
Frequently asked questions
- What is a bookkeeping firm worth?
- Most bookkeeping firms transact at about 2.5x to 3.3x SDE, 3.5x to 4.6x EBITDA, or 1.0x to 1.2x revenue. A firm with $300,000 in earnings is therefore commonly worth somewhere in the high six figures to low seven figures, depending on service mix and transferability.
- Why is the multiple different from the “1x revenue” rule for accounting firms?
- The 1x revenue rule of thumb is built around tax and compliance practices. Bookkeeping firms are valued more reliably on earnings, where the recurring, higher-margin nature of monthly work shows up as a stronger EBITDA multiple.
- Does adding advisory services really increase firm value?
- Yes. Advisory and client-accounting-services revenue carries higher margins and stickier clients, both of which push the multiple toward the top of the range. A buyer pays more for recurring, defensible revenue than for commoditized compliance work.
- What is SDE versus EBITDA?
- SDE adds the owner’s salary, benefits, and personal expenses back into earnings, which fits small owner-run firms. EBITDA does not assume an owner-operator, so buyers use it once a firm is large enough to run on hired staff.
