- A bookkeeper records what happened; an accountant decides what it means and files it.
- Low volume and no VAT usually means an accountant once a year, no bookkeeper.
- VAT, payroll or a backlog is the point where you need both.
The difference between a bookkeeper and an accountant is simple: a bookkeeper records what your business does, and an accountant decides what those records mean and takes responsibility for what gets filed. If you want that handled properly, Sleek gives you accounting handled by qualified accountants with the day-to-day bookkeeping sitting underneath it. But you might not need both, and knowing which one you’re actually hiring saves you money.
A business with low transaction volume and no VAT registration usually needs an accountant once a year and no bookkeeper at all. Once you’re VAT registered, running payroll, or handling more transactions than you can reconcile in an evening, you need both. Most people arrive at this question because something has already gone unrecorded for a few months, so this guide is built to tell you which of the two to hire, and what to do if you’re already behind.
What does a bookkeeper actually do?
A bookkeeper keeps the record straight. Their work is the daily and weekly stuff that makes everything else possible: matching money in and out of the bank against invoices and receipts, entering bills, and keeping the ledger clean enough that someone can trust it later.
Day to day, that usually means:
- Reconciling the bank so every transaction is matched to an invoice or a receipt.
- Raising and chasing sales invoices, and keeping an eye on trade debtors so you know who owes you.
- Entering supplier bills and expenses, and filing the paperwork behind each one.
- Preparing the payroll figures so they’re ready for whoever runs the pay run.
None of this involves an opinion about your tax. A bookkeeper isn’t deciding how you pay yourself or which VAT scheme suits you. They’re making sure that when those decisions get made, they’re made on numbers that are actually right. If you’d rather not do it yourself, outsourced bookkeeping run in Xero keeps the ledger current without you touching it.
What does an accountant actually do?
An accountant interprets the records and owns what gets filed. Where the bookkeeper says what happened, the accountant says what it means and signs their name to it with HMRC and Companies House.
That covers the work that carries legal weight:
- Preparing your statutory accounts and the corporation tax return.
- Choosing the right VAT scheme and handling the returns once you’re registered.
- Advising how you pay yourself, splitting salary and dividends sensibly.
- Dealing with HMRC correspondence and any enquiry that lands.
This is why a limited company usually wants a qualified accountant on the file rather than a bookkeeper alone. If your accounts have to be filed and defended, you want an accountant for a limited company who takes responsibility for the numbers, not just someone who recorded them.
What do the qualifications actually mean?
The two roles train differently, and it helps to know what the letters after a name signify. A bookkeeper may hold AAT or ICB membership, which shows they’re trained to keep records accurately and to a recognised standard.
An accountant working on statutory accounts is typically ACA, ACCA or CIMA qualified. That’s a longer route, and it’s what lets them sign off accounts and advise on tax with professional accountability behind it. This is not a case of one being skilled and the other not. A good bookkeeper is highly skilled at what they do; the qualifications simply mark out who is trained to take responsibility for filings and tax advice.
A year in one company’s books: who does what, and when?
The split is easiest to see if you walk a single company through a year. Picture a small limited company on a 31 March year end, VAT registered, with one employee.
Through the year, the bookkeeper is working every week: reconciling the bank, entering bills, keeping the ledger tidy. Each quarter, the bookkeeper prepares the numbers for the VAT return and the accountant checks the scheme is still right before it’s submitted. Every month, the payroll figures the bookkeeper prepared feed the pay run and the PAYE submission to HMRC.
Then the year end arrives. The accountant takes the clean ledger the bookkeeper has kept and turns it into statutory accounts and the corporation tax return, decides the final salary and dividend position, and files everything with Companies House and HMRC to deadline. The pattern is the point: the bookkeeper keeps the record all year so the accountant can do the filing at the end without a scramble. When the ledger is a mess, the year end becomes a clean-up job before any real accounting can start, and that costs more.
Which one do you need right now?
Most of the decision comes down to a few triggers. Run through them honestly and the answer usually becomes obvious.
You probably need a bookkeeper (on top of an accountant) once any of these are true:
- You’re VAT registered, so there’s a return to prepare every quarter. Registration is compulsory once your taxable turnover passes £90,000 in a rolling 12 months.
- You run payroll, so there’s a monthly cycle to keep on top of.
- You have more transactions than you can comfortably reconcile in one evening a month.
- You’re already behind, and the records need bringing back to a state an accountant can work from.
If none of those apply, a one-person service business with twenty transactions a month for instance, then the honest answer is often an accountant once a year and no bookkeeper. Don’t buy bookkeeping you don’t need. The trigger for adding it is real volume or a statutory obligation, not the calendar.
| Task | Bookkeeper | Accountant |
|---|---|---|
| Daily bank reconciliation | Owns it | – |
| Raising and chasing invoices | Owns it | – |
| Payroll processing | Prepares figures | Advises on tax treatment |
| VAT return preparation | Prepares the numbers | Reviews and submits |
| Choosing the VAT scheme | – | Owns it |
| Year-end statutory accounts | – | Owns it |
| Corporation tax return | – | Owns it |
| Director’s loan and dividend decisions | – | Owns it |
| HMRC enquiry | Supplies records | Owns the response |
| Confirmation statement | – | Usually files it |
When do you need both?
For a growing business the answer is usually both, and the smart version is both from the same place. The friction most people don’t see coming is the handover: a separate bookkeeper keeps the ledger, then hands it to a separate accountant at year end, and the two spend billable time reconciling their versions of reality before any filing happens.
When the same firm does both, there’s no handover. The people keeping the records and the people filing the accounts are looking at the same live ledger all year, so nothing gets lost in translation and the year end is quiet. This is where accounting handled by qualified accountants with bookkeeping underneath it earns its keep, one engagement, one point of contact, one version of your numbers.
If your current setup already feels like it’s creaking, or you’re thinking about changing accountants because things fall between the gaps, that handover friction is often the real reason.
What does each one cost?
The two roles are priced on different things, which is worth understanding before you compare quotes. Bookkeeping is usually priced on volume: how many transactions there are to reconcile and how many bills and invoices go through each month.
Accounting is usually priced on complexity: how involved your statutory accounts and tax position are, not how many receipts you have. That’s why a simple company with high transaction volume can pay more for bookkeeping than for accounting, and a complex one with few transactions the other way around. For a sense of the accountant side, the guide to what an accountant costs for a limited company sets out how the fee is built up. If you’re taking over a messy set of records, expect an initial piece of work to sort the opening balances before ongoing pricing settles.
How Sleek helps with choosing a bookkeeper or accountant
Sleek pairs qualified accountants with the bookkeeping that feeds them, so you’re not managing two providers or refereeing a handover. A real accountant is accountable for what gets filed, the AI does the heavy lifting on the records, and you can see what was done and what was checked.
If you’re not sure which of the two you need, the quickest answer is to have someone look at your books as they stand and tell you.

FAQs on bookkeeper vs accountant
Can a bookkeeper file my company accounts?
No. Filing statutory accounts and the corporation tax return is accountant’s work, and for a limited company you’ll want someone ACA, ACCA or CIMA qualified taking responsibility for it. A bookkeeper prepares the records those filings are built from, but they don’t sign them off.
Do I need a bookkeeper if I already use Xero?
Xero is the tool, not the person operating it. It makes reconciliation faster, but someone still has to match transactions, chase what doesn’t fit and keep the ledger honest. If you have the time and the discipline, you can be your own bookkeeper in Xero; if you don’t, that’s exactly the job a bookkeeper does.
Is it cheaper to hire a bookkeeper than an accountant?
Usually, per hour, because the work is less specialised. But it’s the wrong comparison, since they do different jobs. A bookkeeper can’t replace the accountant who files your accounts, so for most limited companies the real question is whether you need a bookkeeper on top of the accountant, not instead of one.
Can one firm do both, or do I need two providers?
One firm can do both, and for most growing businesses that’s the better option. Keeping the records and filing the accounts under one roof removes the year-end handover, where a separate bookkeeper and accountant spend billable time reconciling their two versions of your numbers.
What happens if my bookkeeping is behind before I hire an accountant?
The accountant has to bring the records up to date before they can file anything, which is a clean-up job priced separately from ongoing work. It’s worth being upfront about a backlog when you get a quote, because it’s cheaper to fix than to discover halfway through a year end.
Does a sole trader need a bookkeeper?
Often not. A sole trader with modest turnover and few transactions can usually keep their own records and use an accountant once a year for the tax return. A bookkeeper starts to earn their fee once the volume grows or VAT and payroll come into play.
Do bookkeepers deal with HMRC on my behalf?
Not for the things that carry liability. A bookkeeper may submit a VAT return that’s been reviewed, but tax advice, corporation tax and any HMRC enquiry sit with the accountant, who is the one accountable for the position taken.
