Here's an odd thing for a bookkeeper to say: plenty of small limited companies don't need one, at least not yet. Xero has made doing your own books far more realistic than it used to be. Your bank transactions flow in automatically, you can snap receipts on your phone, and it files your VAT return straight to HMRC.
So the real question isn't "can I do it myself?" It's "is doing it myself still the best use of my time?" Here's how to tell.
When DIY in Xero works well
Doing your own books is a perfectly sensible choice if most of these are true:
You've got a manageable number of transactions, say a few dozen a month rather than hundreds
You're not VAT registered yet, or your VAT is simple (one rate, no imports, no complicated schemes)
There's no payroll, or it's just you as director on a simple salary
You actually do it regularly. A weekly 20-minute session to reconcile the bank and attach receipts keeps it painless.
You trust the numbers. You could tell someone roughly what profit you made last month without guessing.
If that's you, keep going. Just make sure Xero was set up properly in the first place: the right chart of accounts, VAT settings and bank rules. A wonky setup quietly causes problems that only show up at year end.
Five signs it's time to get help
1. You're always behind
If the bank reconciliation screen says hundreds of items, or you're catching up months at a time, the books aren't doing their job. Out-of-date numbers mean decisions made on gut feel, and a stressful scramble before every deadline.
2. You've registered for VAT (or you're getting close)
All VAT-registered businesses must keep their VAT records and file returns using compatible software under Making Tax Digital. Each return and payment is due one calendar month and 7 days after the end of the VAT period. Mistakes here cost real money, either in overpaid VAT or in penalties and interest, and the £90,000 rolling 12-month threshold creeps up faster than people expect.
3. You've taken on staff
Payroll is where DIY gets risky. Every time you pay people, you have to report it to HMRC on or before payday. PAYE is then due by the 22nd of the following tax month, with workplace pensions and auto-enrolment on top. It's very doable, but it's relentless and unforgiving.
4. Your time is worth more elsewhere
Do the maths honestly. If the books take you 6 hours a month and your time is worth £50 an hour on paid work, that's £300 a month of your time. That's before the evenings you lose and the stress of doing something you don't enjoy. A bookkeeper is often quicker, because it's all we do.
5. You don't really trust what Xero is telling you
If the profit figure looks wrong, the bank balance in Xero doesn't match your actual bank, or your accountant sends back a list of questions every year end, the books need a proper tidy-up and a second pair of eyes.
The middle ground most people don't know about
It doesn't have to be all or nothing. Some of the most common setups I see:
You do the day-to-day, I review monthly. You keep coding transactions and snapping receipts. Once a month I check, correct and reconcile, so nothing drifts.
I do the books, you just snap receipts. You photograph receipts into Xero (or Apron) and forward invoices. Everything else is handled.
A one-off setup or clean-up. I get Xero set up properly or untangle a messy year, and then you take it from there.
A quick self-test
Answer yes or no:
Is your Xero bank reconciliation up to date right now?
Could you say what profit you made last month within a few hundred pounds?
Are you confident your VAT returns are right (or that you're nowhere near the threshold)?
Do you spend less than 2 hours a month on bookkeeping?
Do you (mostly) not mind doing it?
Mostly yes: DIY is working. Keep going, and maybe get an annual check-up. Two or more "no"s: it's worth a conversation.
The takeaway
Xero makes DIY bookkeeping possible, but possible isn't the same as worth it. The right time to bring in a bookkeeper is usually when the books start costing you more, in time, stress or mistakes, than the help would.
If you're not sure which side of the line you're on, get in touch. I'll tell you honestly, even if the answer is "you're doing fine on your own".
This is general guidance based on GOV.UK and HMRC rules at the time of writing. Check with your bookkeeper or accountant for advice on your own circumstances.
