Outsourced bookkeeping: what it costs, and when it's worth it
Outsourcing the books is usually cheaper than hiring, and almost always better than doing it yourself at 11pm. The real question isn't whether to outsource — it's whether you need a generalist or a specialist.
Outsourced bookkeeping is paying an external firm or contractor to maintain your financial records — categorising transactions, reconciling accounts, and closing the books each month. It typically costs $300–$2,500 a month depending on transaction volume, number of accounts, and whether you need reporting beyond a basic P&L. It usually beats hiring in-house until you pass roughly $5M in revenue, because a full-time bookkeeper costs $55,000–$75,000 loaded and most businesses do not have a full-time amount of work.
What does outsourced bookkeeping include?
The floor is transaction categorisation and reconciliation. Everything above that is a pricing decision.
Almost every provider will do the same base layer: pull your bank and card feeds, categorise what comes through, reconcile the accounts against statements, and produce a profit and loss, balance sheet and cash flow statement each month.
Where providers diverge is everything after that. The gap between a $300 provider and a $1,600 provider is rarely the reconciliation — it's whether anyone is applying judgement to how your specific business should be structured.
| Layer | Typically included at | What it means |
|---|---|---|
| Categorise and reconcile | $300+ | Transactions coded, accounts tied out to statements |
| Standard monthly reports | $300+ | P&L, balance sheet, cash flow |
| Accounts payable / receivable | $800+ | Bills paid and invoices chased on a schedule |
| Industry chart of accounts | $800+ | Structure built for how your business actually works |
| Revenue recognition schedules | $1,200+ | Deferred revenue, prepayments, multi-period contracts |
| Segment or client profitability | $1,500+ | Cost allocated to the units you make decisions about |
| Cash forecasting | $2,000+ | Forward view, not just historical reporting |
A useful test when comparing quotes: ask what happens to an unusual transaction. A cheap provider codes it to whatever looks closest and moves on. A good one queues it, asks you, and writes a rule so it never has to ask again.
How much does outsourced bookkeeping cost?
Pricing is almost always driven by transaction volume rather than revenue, because volume is what drives the work. Two businesses with identical revenue can differ fourfold in cost if one runs everything through three accounts and the other has eleven.
| Monthly transactions | Typical monthly cost | Usually suits |
|---|---|---|
| Under 100 | $200 – $400 | Solo operators, simple structures |
| 100 – 300 | $400 – $900 | Small teams, one entity |
| 300 – 600 | $900 – $1,800 | Growing businesses, multiple accounts |
| 600 – 1,200 | $1,800 – $3,000 | Multi-entity, multi-currency, or heavy AP/AR |
| 1,200+ | $3,000+ | Usually priced bespoke |
Two costs people forget to budget for. Catch-up work is quoted separately and billed once — if you are months behind, someone has to rebuild that history before ongoing work can start, and it is real labour. And cleanup or re-charting, if your existing structure is wrong, is a one-time project rather than something absorbed into a monthly fee.
If a provider quotes a monthly fee without asking about transaction volume, number of accounts, or how far behind you are, the quote will change later. Get those three questions asked before you sign.
Outsourced versus in-house
The arithmetic is usually decisive until you get large.
| Outsourced | In-house hire | |
|---|---|---|
| Annual cost | $3,600 – $30,000 | $55,000 – $75,000 loaded |
| Coverage when they're away | Built in | Nothing happens |
| Reviewer behind them | Usually | Rarely |
| Knows your industry | If you pick a specialist | Only if you hire for it |
| Scales with volume | Repricing conversation | Another hire |
| Worth it above | — | Roughly $5M revenue or genuinely daily volume |
The honest case for hiring in-house is not cost. It is when the bookkeeping is entangled with operations — someone who also handles billing disputes, chases collections, and sits in on resourcing conversations. That is a different job than bookkeeping, and it should be hired as one.
When a specialist beats a generalist
If your industry has an accounting quirk, a generalist will guess at it — and they will guess consistently, for years, before anyone notices.
General-practice bookkeepers are good at the common shapes: retail, trades, professional services. They see those every week. What they do not see is the structural oddity specific to your sector, so it gets handled by analogy to something else.
Some of the sectors where this bites hardest:
- Agencies and marketing firms — client media spend passing through the business, retainers billed in advance, and a contractor bench that has to be split between delivery and overhead. Book the pass-through as revenue and every ratio in the business is wrong.
- Ecommerce — inventory, cost of goods, marketplace fees and returns landing across several platforms and settlement cycles.
- Law firms — client trust accounts, which have their own compliance regime and are unforgiving of sloppiness.
- Property management — money held on behalf of owners, which is not the manager's revenue and must never be commingled.
- Construction — job costing, work in progress, retainage, and percentage-of-completion revenue.
The tell is the same everywhere: money that moves through your accounts but was never yours, or revenue that arrives before the work does. Both are easy to book wrong and expensive to unpick.
For agencies specifically, the most common and costly version is client advertising spend booked as revenue. We wrote the full explanation of why that happens and what it costs you.
How to choose a provider
- Ask who actually touches your file. A named person with a reviewer behind them, or a rotating pool and a shared inbox. This is the single biggest quality difference and it is rarely on the pricing page.
- Ask for the close date, not the close window. "Within two to three weeks" means the fifteenth some months and the twenty-eighth others. Reconciliation has a right answer, so a firm can commit to a date.
- Ask what happens when they do not recognise a transaction. The answer tells you whether you are buying judgement or data entry.
- Check they will not hold your ledger hostage. You should be able to leave with your file and every working paper. Anyone hesitant here is telling you something.
- Confirm what is not included. Tax filing, payroll, AP/AR and advisory are frequently separate. A cheap monthly fee with four add-ons is not cheap.
- Ask what they would change about your chart of accounts. A specialist will have an opinion within ten minutes. A generalist will say it looks fine.
Where AI actually changes the price
Most bookkeeping firms now use some form of automated matching, and the good ones are honest about where it helps. Bank feed lines matched against invoices, bills and receipts, coding rules learned from your history, anomalies flagged for review — that is genuine volume work a machine does well.
What it does not do is decide how your business should be structured, or make judgement calls on ambiguous transactions. The useful question to ask a provider is not whether they use AI. It is who reviews its output and whose name is on the close.
Where this should show up for you is in the shape of the service rather than a discount. The same money buys more: a faster close, more reporting, more exceptions actually investigated instead of coded to miscellaneous.
Common questions
How much does outsourced bookkeeping cost per month?−
Typically $300 to $2,500 a month. Under 100 transactions usually lands at $200–$400; 300–600 transactions at $900–$1,800; above that, expect $1,800–$3,000 or bespoke pricing. Volume, number of connected accounts and reporting depth drive the number more than revenue does. Catch-up work for prior months is quoted separately and billed once.
Is outsourced bookkeeping cheaper than hiring someone?+
Almost always, until roughly $5M in revenue. A full-time bookkeeper costs $55,000–$75,000 fully loaded, and most businesses under that threshold do not have a full-time amount of bookkeeping. Outsourcing also gives you coverage when someone is on holiday and usually a reviewer behind the person doing the work, both of which a single hire does not.
What's the difference between bookkeeping and accounting?+
Bookkeeping is the ongoing record: categorising transactions, reconciling accounts, closing each month, producing statements. Accounting sits on top — tax filing, assurance, advisory and formal opinions, which in most jurisdictions require a licence. Many firms do only one deliberately. Clean books handed to an accountant makes their work faster and cheaper.
Do I have to change accounting software?+
You should not have to. Most providers work inside QuickBooks Online or Xero, whichever you already use. Be cautious of any provider that requires you to move onto proprietary software — it makes leaving expensive, which is precisely why some of them do it.
How far behind is too far behind?+
There is no such thing. Being six to twelve months behind is extremely common and is most firms' normal intake. It gets quoted as a one-time catch-up project. The genuine risk of waiting is not the bookkeeping — it is filing deadlines, and making decisions all year on numbers nobody has checked.
We only do agencies
Pass-through separated, retainers recognised monthly, margin by client. If that's not your problem, a good generalist is cheaper and we'll say so.
