For a typical small business in 2026, bookkeeping costs between $0 and $12,000 a year depending on who does it: a part-time bookkeeper runs roughly $3,000–$12,000/yr, outsourced services $2,400–$7,200/yr, DIY software $456–$3,300/yr plus 3–6 hours of your month, and the newest option, your own AI agent on free software, $0–$108/yr. Here's the honest math on each, including the cost everyone leaves off the invoice: your time.
First, price your own hour
Every comparison below includes “your hours,” so pick a number: what an hour of your evening is worth. Most owners land between $50 (opportunity cost floor) and their billing rate. At even $50/hr, the “free” spreadsheet that eats four hours a month costs $2,400 a year. Keep that number in mind; it flips more verdicts than any subscription price.
Option 1: A human bookkeeper, $3,000–$12,000/yr
Freelance bookkeepers typically bill $40–$100/hr or $250–$1,000/mo for a small business, scaling with transaction volume. What you're really buying: judgment, accountability, and never thinking about it. Where it disappoints: turnaround (questions answered on their schedule), and the fact that most of the invoice pays for mechanical categorization a machine now does. Best fit: complex books (inventory, payroll, multiple entities) or owners who genuinely will not review anything, ever.
Option 2: Bookkeeping services, $2,400–$7,200/yr
Productized services (Bench being the famous name) charge $199–$599/mo for human teams working in their platform, as of July 2026. Cheaper than a dedicated bookkeeper, but two structural catches: the work happens on a monthly cycle, and your books usually live in a proprietary system. The Bench shutdown scare of December 2024 showed what that can mean. Also note most service tiers exclude tax filing; your CPA is a separate bill either way.
Option 3: DIY software, $456–$3,300/yr plus your hours
QuickBooks Online lists at $38–$275/mo per company as of mid-2026 ($456–$3,300/yr), and each additional business is another subscription. Wave's free plan covers invoicing but wants $19/mo per business for bank feeds and auto-categorization. The subscription is only half the price, though: the model is you in the app, clicking through rows. At 2–4 hours a month and $50/hr, add $1,200–$2,400/yr of your time to any of these. The AI “assist” features suggest categories, but the hands are still yours.
Option 4: Your AI agent on free software, $0–$108/yr
The 2026 addition to the menu: agent-native software, where the AI you already subscribe to does the work. The stack prices out like this:
- Software: $0. LedgerMCP is free: unlimited books, all reports, full agent access.
- Bank feeds (optional): $9/mo covers up to five connected accounts, pooled across all your books. Skip it and import CSVs free.
- The AI: the Claude or ChatGPT plan you're paying for anyway, so the marginal bookkeeping cost is zero.
- Your hours: the real saving. Review-only bookkeeping runs 10–20 minutes a month (the close checklist shows why). Call it $100–$200/yr of time instead of $1,200–$2,400.
The full comparison, one table
| Option | Cash cost /yr | Your hours /mo | True cost /yr @ $50/hr | Turnaround |
|---|---|---|---|---|
| Part-time bookkeeper | $3,000–$12,000 | ~0.5 | $3,300–$12,300 | Days–weeks |
| Bookkeeping service | $2,400–$7,200 | ~0.5 | $2,700–$7,500 | Monthly cycle |
| DIY software (QBO etc.) | $456–$3,300 per company | 2–4 | $1,656–$5,700 | Whenever you sit down |
| Spreadsheet | $0 | 3–6 | $1,800–$3,600 (+ error risk) | Whenever you sit down |
| AI agent + free software | $0–$108 | 0.2–0.4 | $120–$350 | Minutes |
The honest caveats
- Complex needs change the math. Payroll, inventory, invoicing, multi-currency: the agent route (on LedgerMCP at least) deliberately doesn't do those. A business built on them should price QuickBooks or a bookkeeper who owns the whole stack. We say so directly in our own comparison.
- Someone still reviews. The AI option is cheap because it converts your role from data entry to review, not to nothing. If truly nobody will look at the books, pay a human (or hire a bookkeeper who runs the agent workflow, which is increasingly common, and cheaper than the old model).
- Your CPA is constant. Tax prep is a separate line in every scenario. What changes is what you hand them: reconciled, immutable, audit-trailed books make that engagement cheaper too.
- Behind right now? Catch-up quotes from services often run $200–$500 per backlogged month. The agent catch-up workflow does a year in an afternoon for $0. It's the single biggest arbitrage in this whole article.
Bottom line
The 2026 answer to “what should bookkeeping cost?” is: mostly your review time. The mechanical layer, the thing that used to justify every one of those invoices, is now handled by the AI you already pay for, on software that's free, with a ledger that makes its mistakes reversible. Try it against your real books before you renew anything: free account, connect Claude or ChatGPT, one statement, and compare the hour you spent to last month's.
