Receipts and Expenses: How to Keep Clear Records in a Small Business

Ask most small business owners what they like least about bookkeeping and "chasing receipts" is near the top of the list. The good news is that a few simple habits make it far easier. Clear expense records also support your accountant's work and any questions from Revenue.

What a good record includes

For each expense, you should be able to show:

• The date and who you paid.
• What it was for and how it relates to the business.
• The amount.
• The invoice or receipt itself.
• How it was paid, so it can be matched to your bank.

Five habits that work

1. Capture it straight away. Photograph paper receipts with your phone or accounting app the day you get them, before they fade, fold or vanish.
2. Send emailed invoices to one place. Use a dedicated folder or a mailbox address your software can read.
3. Attach the document to the transaction. Most accounting software lets you link the receipt to the bank transaction, so it is always found in one place.
4. Use a business bank account and card. This keeps personal spending out of your records. When you do pay for something business-related personally, note it clearly so it is recorded properly.
5. Do a short weekly check. Ten minutes categorising and matching transactions beats a mountain at month-end.

Keep personal and business spending separate

Mixing the two is one of the most common causes of messy books. A separate account is the simplest fix; see our start-up checklist. If something is part business and part personal, ask your accountant how it should be treated before you record it.

What if you lose a receipt?

Ask the supplier for a copy, check your emails or look for a statement or online account showing the purchase. Record what you can, and make a note of what is missing. Do not guess or create documents after the event.

How long to keep them

Business records generally need to be kept for six years. See how long to keep bookkeeping records for details.

Reconcile to catch gaps

A monthly bank reconciliation shows you every payment that left your account, which makes any missing receipts easy to spot while they are still easy to find.

Build it into the moment

The reason receipts get lost is that filing them is a separate task from spending the money, and separate tasks get postponed. The fix is to collapse the two into one: photograph the receipt while you are still standing at the counter, or forward the email invoice the moment it lands rather than leaving it in your inbox. Thirty seconds at the point of spending replaces an hour of archaeology at month-end.

If you drive, keep a habit for fuel and tolls specifically, since these are the receipts most often missing. If you buy online, a monthly scan of your main supplier accounts will catch invoices that were never emailed.

Cash, cards and who paid

Record not just what was bought but how it was paid, because that determines how it is recorded:

• Business card or bank transfer: the transaction will appear in your bank feed and simply needs matching and a receipt attached.
• Cash: there is no bank record, so the expense has to be entered deliberately or it disappears entirely.
• Personal money: this needs to be recorded so the business can reimburse you or account for it properly. Note it the same day.
• Employee expenses: agree a simple claim routine and a cut-off date each month so claims do not arrive after the books are closed.

Subscriptions deserve an annual review

Recurring software, insurance and service subscriptions are the quietest drain on a small business, because each one is small and none of them demand attention. Once a year, list every recurring payment leaving your account, check you still use each, and cancel what you do not. A reconciled bank account makes this list easy to produce.

What good looks like

You know your expense records are working when you can pick any transaction from three months ago, see what it was for and open the receipt without searching for it. If you can do that, your accountant has fewer questions and you can answer any query from Revenue with confidence rather than apology.
