Outsourced Accounting Services: What They Cost and How They Work (2026)

Outsourcing your accounting means handing the bookkeeping, month-end close and financial reporting to an outside firm instead of hiring staff. For most US small businesses it costs less than one part-time employee and covers more. This guide explains what is included, what it costs in 2026, and how to choose a provider.

What do outsourced accounting services include?

A typical engagement covers the full monthly cycle: recording and categorising transactions, reconciling every bank, card and loan account, accounts payable and receivable, payroll, sales tax filings, and a month-end close that produces a profit and loss, balance sheet and cash flow statement. Larger engagements add budgeting, forecasting and a fractional controller or CFO who explains what the numbers mean.

What it does not usually include is the annual income tax return, which is often quoted separately, and audit work, which has to be independent.

How much do accounting outsourcing services cost in the USA?

For a US small business, expect these monthly ranges in 2026:

• Bookkeeping only: $300 to $1,500, driven by transaction volume and the number of accounts and sales channels.
• Bookkeeping plus payroll and sales tax: $600 to $2,500.
• Full outsourced accounting with a controller review: $1,500 to $5,000.
• With fractional CFO support: $3,000 to $10,000.

Compare that with hiring. A full-charge bookkeeper costs $55,000 to $70,000 a year before payroll taxes, benefits and software, and a controller is well over $100,000. Outsourcing gets you a slice of both for a fraction of either.

Fixed fee or hourly?

Choose a fixed monthly fee for ongoing work. It makes the cost predictable and gives the provider the incentive to be efficient. Hourly billing is reasonable only for one-off projects where the scope is genuinely unknown, such as a multi-year cleanup, and even then you should ask for a capped range.

Onshore, offshore or hybrid?

Offshore-only providers are the cheapest and can be fine for high-volume data entry, but US sales tax, payroll and state filing rules are where they most often go wrong. Onshore firms cost more and know the rules. A hybrid model, where a US-focused accountant owns the file and the review while a wider team handles volume, is how most modern firms keep both quality and price under control. Ask any provider who signs off on your month-end and whether that person has worked on US books before.

Who should outsource their accounting?

• Businesses between roughly $250,000 and $10 million in revenue that have outgrown a spreadsheet but do not need a full finance department.
• Ecommerce brands with Shopify, Amazon and multi-state sales tax, where payout reconciliation is a specialism in itself.
• Founders who are still doing the books at night.
• CPA and tax firms that want white-label bookkeeping capacity without adding headcount.

What should you ask before signing?

1. Who is my named contact, and who reviews their work?
2. Which software do you work in, and are you certified in it? QuickBooks Online and Xero are the standard.
3. By what date each month will I have reconciled reports?
4. Is the fee fixed, and what would make it change?
5. How do you access my bank and accounting data, and can I revoke it in one click?
6. Can I see a sample month-end package?

How does onboarding work?

A good provider starts with view-only access to your accounting file and tells you what state it is in. Most files need some cleanup or catch-up first, which should be quoted as a fixed one-time project. After that the monthly rhythm is simple: documents and bank feeds arrive in the first week, questions come to you in one batch, and reports land by mid-month.

Is outsourced accounting secure?

It should be more secure than emailing spreadsheets. Cloud accounting software gives your provider their own login with accountant-level permissions, bank feeds are read-only, and you can remove access instantly. Avoid any provider that asks for your banking password.

Cloud Accountants provides outsourced accounting services to US businesses and CPA firms on QuickBooks Online and Xero, for a fixed monthly fee. If you are not sure where your books stand, start with a free books review: send view-only access and we will tell you what is wrong within 48 hours.
