¿Cuánto costará la contabilidad subcontratada en 2026? (Precios por hora, mes y por transacción)

Outsourced bookkeeping costs between $300 and $2,500 per month for most small and mid-sized businesses in 2026. Hourly rates run $25 to $90 depending on provider location and seniority, fixed monthly plans dominate the market at $300 to $1,200 for businesses under $5M revenue, and per-transaction pricing — increasingly common with automation-heavy providers — lands between $0.50 and $2.00 per transaction. A business doing 300 transactions a month with two bank accounts and monthly reporting should budget roughly $500 to $900 per month for a quality provider.

Those are the headline numbers. The real answer depends on five variables: transaction volume, the accounting platform you run, how clean your books are today, how much of the work is automated, and whether you need bookkeeping alone or bookkeeping plus controller-level review. This guide breaks down each pricing model with real 2026 ranges so you can benchmark quotes — whether your books live in Odoo, QuickBooks Online, Xero, or a mix of systems.

Key Takeaways

• Fixed monthly pricing is the dominant model in 2026: $300–$700/month for micro businesses, $700–$1,500 for SMBs, $1,500–$4,000+ for multi-entity or inventory-heavy companies
• Hourly bookkeeping runs $25–$45 offshore, $40–$70 US/EU freelance, $70–$90+ for firm-based senior bookkeepers
• Per-transaction pricing ($0.50–$2.00) rewards businesses with high automation — bank feeds and AI categorisation cut billable touches dramatically
• Platform matters: well-configured Odoo or Xero books with live bank feeds cost 20–40% less to maintain than spreadsheet-driven or poorly set up files
• Catch-up and cleanup work is billed separately, typically $500–$5,000 one-time depending on how many months are behind
• In-house bookkeepers cost $45,000–$65,000+ fully loaded in the US — outsourcing breaks even for most businesses under roughly 1,500 transactions per month
• The cheapest quote is rarely the cheapest outcome: re-categorisation, missed reconciliations, and tax-time cleanup erase apparent savings

The Three Pricing Models Explained

Every outsourced bookkeeping quote you receive in 2026 will follow one of three structures — or blend them.

Hourly Pricing

Hourly billing is the oldest model and still common for irregular workloads, cleanup projects, and advisory-heavy engagements.

The weakness of hourly pricing is misaligned incentives: slower work earns more. It works best when you cap hours monthly and review time logs. As a sanity check, a typical SMB with 200–400 monthly transactions needs 8–15 bookkeeping hours per month once the system is set up properly.

Fixed Monthly Pricing

Fixed monthly plans are now the default for ongoing engagements because both sides get predictability. Pricing is usually tiered by transaction volume, number of accounts, and reporting depth.

Watch the inclusions carefully. A $400 plan that excludes accounts payable processing, payroll journal entries, and sales tax filings can quietly become an $800 plan. Always ask for the full scope list: number of bank and credit card accounts reconciled, AP/AR handling, payroll integration, sales tax, month-end reporting package, and response-time commitments.

Per-Transaction Pricing

Per-transaction pricing has grown fast since 2024 because automation made per-unit costs measurable. Providers charge $0.50–$2.00 per transaction, sometimes with a platform minimum of $200–$300 per month.

This model strongly favours businesses with clean automation: direct bank feeds, AI categorisation rules, OCR-based invoice capture, and integrated payment platforms. If 90% of your transactions auto-match and the bookkeeper only handles exceptions, you should be paying at the bottom of the range. If every transaction needs manual touch, per-transaction pricing gets expensive fast — a 1,000-transaction month at $1.50 is $1,500 for work a fixed plan might cover at $1,200.

What Actually Drives Your Price

Transaction volume is the headline variable, but four other factors move quotes by 30–50% in either direction.

Platform and configuration quality. Books on a modern cloud platform with live bank feeds — Odoo, Xero, QuickBooks Online — cost meaningfully less to maintain than desktop software, spreadsheets, or a badly configured cloud file. Providers quietly price in the pain. A well-structured chart of accounts with automation rules can cut monthly bookkeeping effort by 40% compared to an identical business with a cluttered, rule-free setup. If your Odoo or QuickBooks instance was never configured properly, fixing the foundation often pays for itself within two quarters of lower fees.

Inventory and ecommerce complexity. Cost of goods sold tracking, landed costs, marketplace settlements (Amazon, Shopify payouts that bundle fees, refunds, and reserves), and multi-channel reconciliation add real hours. Expect ecommerce books to cost 30–60% more than a service business at the same transaction count.

Payroll and headcount. Payroll journal entries, benefits accruals, and contractor payments scale with employee count. Many providers price payroll support per employee per month ($4–$10) on top of the base plan.

Catch-up and cleanup. If your books are behind or unreliable, providers bill a one-time cleanup project before starting a monthly plan:

Reporting and review depth. Basic plans deliver a P&L and balance sheet. Controller-level packages — accrual adjustments, variance commentary, cash flow forecasting, board decks — add $300–$1,000+ per month but are usually cheaper than hiring a part-time controller separately.

Outsourced vs In-House: The 2026 Break-Even Math

A full-time in-house bookkeeper in the US costs $45,000–$65,000 in salary, plus 20–30% in payroll taxes, benefits, software, and overhead — call it $55,000–$85,000 fully loaded. Even a part-time hire at 20 hours per week runs $25,000–$35,000 annually.

For most businesses under roughly 1,500 transactions per month, outsourcing costs 50–75% less than the in-house equivalent and includes something a solo hire cannot: a second set of eyes. The crossover point arrives when your volume, intercompany activity, or operational tempo demands someone embedded in daily operations — typically somewhere past $10M–$20M revenue, and even then a hybrid (in-house clerk plus outsourced controller) often wins.

How Platform Choice Changes the Bill

Bookkeeping cost is downstream of system design. Three patterns we see repeatedly across Odoo, QuickBooks, and Xero engagements:

Odoo. Businesses running Odoo get the widest automation surface — bank feeds, OCR invoice capture, automated reconciliation models, and native integration between sales, inventory, and accounting. The catch: Odoo rewards proper implementation. A correctly configured chart of accounts, tax mapping, and reconciliation rules can push auto-matching above 90%, which is why per-transaction providers love well-built Odoo instances. A poorly implemented one is the most expensive file a bookkeeper can inherit. If you are on Odoo and your monthly fee seems high, the fix is usually configuration, not a cheaper bookkeeper — a one-time professional Odoo implementation review frequently cuts ongoing fees by more than its cost.

QuickBooks Online. The largest provider ecosystem and the most competitive pricing — almost every firm quotes QBO confidently. Bank rules and receipt capture are mature. Limits appear with inventory depth and multi-entity consolidation, where businesses either add apps (each adding reconciliation surface) or outgrow the platform.

Xero. Comparable to QBO in automation, particularly strong bank reconciliation UX, popular outside the US. Pricing for Xero bookkeeping tracks QBO within 10%.

Mixed or legacy systems. Spreadsheet-driven books, desktop software, or fragmented tools routinely cost 50–100% more to maintain. If your quote seems like an outlier, this is usually why — and a platform migration pays back quickly.

Red Flags and Value Signals When Comparing Quotes

The cheapest quote is rarely the cheapest outcome. A $300/month provider who miscategorises transactions creates tax-time cleanup bills that erase a year of savings.

Red flags:

• No documented month-end close process or delivery calendar
• Reconciliations "as needed" instead of monthly for every account
• No named point of contact or review layer
• Pricing that seems impossible for your stated volume (it is — scope will shrink or quality will)
• Reluctance to give you full admin access to your own books

Value signals:

• A written scope listing every account reconciled and every report delivered
• Automation-first workflow: bank feeds, categorisation rules, OCR capture
• Platform-specific expertise (ask how they would configure reconciliation models in your system, not just "do you know Odoo/QBO/Xero")
• Controller review included or available as a tier
• Clean handoff terms — your data, exportable, anytime

Frequently Asked Questions

How much does outsourced bookkeeping cost per month for a small business?

Most small businesses pay $300–$900 per month in 2026. Under 100 monthly transactions with two bank accounts typically lands at $300–$500; 100–300 transactions with payroll and basic AP runs $500–$900. Ecommerce, inventory, or multi-entity businesses should budget $1,200–$2,500+. Always confirm what is included — reconciled account count, AP/AR processing, and reporting depth move the real price significantly.

Is hourly or fixed monthly pricing better for bookkeeping?

Fixed monthly pricing is better for ongoing bookkeeping because it aligns incentives and makes budgeting predictable — the provider profits by being efficient, not slow. Hourly pricing makes sense for one-time cleanup projects, irregular advisory work, or the first 60–90 days of an engagement while scope is being established. Many businesses start hourly for cleanup, then convert to a fixed plan.

How much does it cost to catch up bookkeeping that is months behind?

Catch-up bookkeeping typically costs $500–$1,200 for 1–3 months behind with simple books, $1,200–$3,500 for 4–12 months, and $3,000–$5,000+ for a full-year rebuild with reconciliation problems. Multi-entity restatements run higher. Get the cleanup quoted as a fixed-fee project separate from the ongoing monthly plan, with a defined completion checklist (all accounts reconciled, balances tied to statements).

Is outsourced bookkeeping cheaper than hiring in-house?

Yes, for most businesses under roughly 1,500 transactions per month. A fully loaded in-house bookkeeper costs $55,000–$85,000 per year in the US, while an equivalent outsourced plan runs $6,000–$18,000 — a 50–75% saving that also adds review oversight a solo hire lacks. In-house starts making sense when daily operational involvement, very high volume, or complex intercompany work demands an embedded person, typically past $10M+ revenue.

Does the accounting software I use change bookkeeping fees?

Significantly. Well-configured cloud platforms with live bank feeds and automation rules — Odoo, QuickBooks Online, Xero — reduce manual touches and cost 20–40% less to maintain than desktop software, spreadsheets, or badly set up cloud files. Per-transaction providers price this directly. If fees seem high for your volume, an implementation review that fixes the chart of accounts, tax mapping, and reconciliation rules usually pays for itself within months.

What should be included in a monthly bookkeeping package?

A complete package includes: categorisation of all transactions, monthly reconciliation of every bank and credit card account, accounts payable and receivable processing (or clear exclusion), payroll journal entries, sales tax tracking, a month-end close on a stated calendar, and a reporting pack with at least P&L, balance sheet, and cash summary. Controller-tier plans add accrual adjustments, variance analysis, and forecasting. Anything not written into scope will eventually be billed extra.
