Clinic expenses: the records that go missing, and a routine that keeps them

An expenses routine has one job. Every pound the practice spends should leave a record your accountant can actually use, without you having to remember anything in March. Most of what goes missing in a private practice was spent properly and then never written down, usually on a personal card between patients.

I spent eleven years doing the books for a private osteopathic clinic, and the spending was never the hard part. Finding it again was. Here is where the records go, and the routine that stops it happening.

The short version

• Most missing expenses were paid on a personal card and never recorded.
• One card that only buys clinic things removes most of the problem.
• Capture the receipt at the moment of payment, never later.
• Reconcile weekly. A missing receipt is findable for about a week.
• Your accountant decides what is allowable. Not you, not me.

Where the records actually go missing

In eleven years I never saw a clinic lose track of a large expense. The rent, the insurance, the couch, the practice software, those all have paperwork attached and a date in the diary. What vanishes is the forty pound order.

The same handful of leaks turn up in nearly every practice. Something bought on a personal card at the till and meant to be sorted out later. An annual software renewal billed to a personal email address that quietly auto-renews. Couch roll and printer paper ordered from a household account because that is where the login lives. Cash for parking at a course. And the associate who buys something useful in March and invoices you for it in August.

None of that is carelessness. It is what happens when the person buying things is also the person treating patients, and the buying happens in the ten minutes between them. The record does not get made because there is no moment in the day where making it is the obvious next thing to do.

Six months later there is a line on a bank statement for £38.40 and nobody can say what it was. That line either gets guessed at or gets dropped, and neither is a good outcome.

One card, and the case for it

The single change that fixes most of this is a card that only ever buys clinic things. Not because it makes the spending smaller, but because it turns the card statement into a complete list. Every line on it is a clinic line, so the job stops being "find the business transactions among the personal ones" and becomes "find the receipt for line eleven".

HMRC's guidance on business records is worth reading on this point, because it is less prescriptive than people expect. It asks that your records are accurate and that you can identify business transactions, and it says you might be able to use a personal or business account, with a note to check with your bank which type of account you can use. The separation is a practical decision rather than a rule handed down from above. It is still the one I would make first.

Being honest about the limits: a separate card does nothing about cash, nothing about the things you bought before you opened it, and nothing about the associate's March receipt. It just shrinks the problem to a size a routine can handle.

A capture routine that survives a busy week

The routine is four steps and none of them are clever. It works because it is small enough to still be happening in week six.

1. At the point of payment, the receipt goes to one destination. Photograph the paper one before it leaves your hand. Forward the email one the moment it lands, while you still have the tab open.
2. Make that destination the thing whoever does your books already opens. Bookkeeping software with a receipt inbox, a shared folder, an email address that only receives receipts. Which one matters far less than there being only one.
3. Name it so it can be found again: date, supplier, amount. A photograph called IMG_4471 is not a record, it is a picture.
4. Once a week, fifteen minutes, run the destination against the card statement. Anything on the statement with nothing behind it gets chased that day.

The weekly step is the one people drop, and it is the one that makes the whole thing work. A missing receipt is easy to find after four days, because you remember the shop and the reason. After four months it is close to unfindable, and after a year it is a guess with a number attached.

Once a month, whatever is still unmatched goes to whoever does the books, flagged as unmatched rather than quietly included. A short honest list beats a long confident one.

The receipts you genuinely cannot find

Some will be gone, and the answer is not to leave the expense out and say nothing. HMRC's guidance covers the situation directly: if records are lost, stolen or destroyed and you cannot replace them, you do your best to provide figures and you say on the tax return whether they are estimated or provisional. That page also sets the retention expectation, which is at least five years after the 31 January submission deadline for that tax year.

That is a safety net rather than a method. If you are using it more than once or twice a year, the capture step is where the problem is, not the filing.

Quarterly changes the arithmetic

If you trade as a sole trader, the timing pressure on all of this has already shifted. Making Tax Digital for Income Tax started on 6 April 2026 for sole traders and landlords whose 2024 to 2025 return showed qualifying income over £50,000. The threshold drops to more than £30,000 from 6 April 2027, and more than £20,000 from 6 April 2028. Qualifying income is turnover before expenses, and HMRC sets out the dates, thresholds and sign-up steps in full.

Where it applies it means digital records, compatible software, and a quarterly update every three months, with the tax return still due by 31 January. This is an Income Tax change, so it lands on sole traders and landlords rather than on clinics that trade through a limited company. Whether and when it reaches you is a question for your accountant, and worth asking now rather than in the week it starts.

The practical point is simple. One annual scramble through a year of receipts is survivable. Four scrambles a year is not, and a routine that only works in January stops working entirely.

What is admin, and what is accounting

I am not an accountant, and this is a line I keep carefully. Deciding whether something counts as an allowable expense is an accountant's judgement against HMRC's rules, and HMRC publishes what sole traders can treat as allowable. Anything with a personal use element, anything involving your home, and anything involving a vehicle is exactly where that judgement earns its fee. Do not take that decision from a blog post, including this one.

The part before it is admin, and it is the part that usually fails. Chasing the receipt, matching it against the statement, naming it, querying the odd line, and handing over a month that adds up. In most clinics I have seen it is an hour or two a month, spread so thin that it never becomes anyone's actual job, which is how it ends up being done at 9pm by the person who should be doing it least.

It is one of the smaller things to hand over, and one of the more obvious. If you want to see what that costs, the rates are on the pricing page, and the hours go on whatever mix of admin a clinic actually needs.

None of this is complicated. It is relentless, which is a different problem, and it only works if the record gets made at the moment of payment. Get that one habit in and everything after it is tidying.
