What's the difference between a bookkeeper, an accountant and an outsourced finance team?

A bookkeeper maintains accurate, current records. An accountant reports on them and meets the agreed filing obligations. An outsourced finance team does both and uses the numbers to support decisions — the same work an in-house finance function would do, without the in-house salary bill. The extent and timing of each depends on the service you agree.

These answers provide general information, not advice tailored to your circumstances. Rules can change and exceptions may apply — speak to the CASS team before making a tax, accounting or financial decision.

The detail

The three roles overlap, which is why the words get used interchangeably — but they answer different questions.

A bookkeeper answers "what happened?". Transactions are recorded and reconciled, suppliers and customers are kept up to date, and the records are accurate enough to rely on.

An accountant answers "what do we have to report?". Year-end accounts, corporation tax, VAT returns and personal tax are prepared and filed correctly and on time.

An outsourced finance team answers "what should we do next?". The bookkeeping and the compliance still happen — they have to — but they become the raw material for management accounts, cash flow forecasting, pricing decisions, hiring decisions and the conversations a business owner would otherwise have with nobody.

In practice

The difference is mostly one of scope and timing. Good ongoing bookkeeping gives you accurate, current records and the reports that come from them. Accounting and tax services meet the agreed reporting obligations. Management reporting and finance advice use those records to support decisions — comparing the month just finished with the months before it while you can still act on it. What you get depends on what has been agreed, not on the job title.

There is real overlap: plenty of bookkeepers flag what they see, and plenty of accountants advise year-round. The practical question is which of these is in your engagement, how often, and who is looking at the numbers with you.

Who this applies to

If your business is small, straightforward, and you are comfortable with the numbers, a bookkeeper and an accountant may be exactly right — and we will tell you so.

The businesses that get the most from an outsourced finance team tend to have some of the following: staff, stock or subcontractors; a growing number of transactions; decisions coming up that need a number behind them; a bank or investor asking questions; or an owner who is currently the finance department as well as everything else.

Common mistakes

Buying the cheapest bookkeeping and expecting insight from it. Insight takes time, and time is the thing the cheapest option removes.

Hiring a part-time finance person before the processes exist, so a good hire spends their first year fixing records instead of improving results.

Assuming software solves it. Xero is very good, and it still only knows what it is told.
