The fryers are off, the counter is wiped, and there is a pile of delivery slips, card receipts and a fish invoice sitting under the till. That pile is your bookkeeping. It is not a separate job you do in January with a shoebox and a bad temper.

Running the numbers for a chip shop is genuinely simple once the system is small enough to survive a busy Friday. What follows is that system, built from three records and five habits.

Start With Three Records, Not One Shoebox

Every chip shop only needs three things written down: what came in, what went out, and what the bank says actually happened. Keep those separate and the rest is arithmetic.

• Sales record — daily takings, split by how the money arrived.
• Expense record — what you bought, when, and how you paid.
• Bank record — the statement, which never lies and never forgets.

A carrier bag of receipts is not a system. It is a delay with a handle on it.

Step One: Build a Daily Sales Sheet

This is the single most valuable page in your business, because it tells you what each channel actually earns. Set up a spreadsheet with one row per day and a column for each payment type. Fill it in at close, or the next morning with a coffee.

What to capture every night

1. The date and the day of the week. You will spot patterns in a month.
2. Cash counted in the drawer, minus the float. Keep the float at the same figure every single night so counting stays boring.
3. The card terminal Z report total, not a guess from memory.
4. Delivery platform payouts — Just Eat, Uber Eats, Deliveroo — with gross sales and commission shown on separate lines.
5. Refunds and voids, so a bad batch of haddock doesn't quietly distort your margins.
6. The day's total, and a note if anything unusual happened. Snow, a power cut, a school holiday, a staff shortage.

Record platform sales at the gross figure and treat the commission as an expense. If you net it off, you lose sight of which channel is worth keeping, and your VAT figures stop matching your returns.

Step Two: Capture Expenses Where They Happen

Fish, potatoes, oil, batter, packaging, wages, gas, electricity, rent, insurance, repairs, card fees. Most chip shop owners can name these off the top of their head, which means the categories can stay broad.

Five categories are plenty

• Stock and ingredients — fish, potatoes, oil, batter, mushy peas, drinks.
• Staff costs — wages, National Insurance, pension contributions.
• Energy and utilities — gas, electricity, water, waste.
• Premises — rent, business rates, insurance, repairs, equipment servicing.
• Everything else — packaging, card fees, marketing, accountancy, subscriptions.

The habit that makes this work is a photo. When you pay for anything, photograph the receipt before it goes in your pocket. One folder on your phone, named by month. If you pay a supplier in cash, write the supplier and what it was bought for on the receipt in pen, there and then. Faded till rolls are the enemy of a tidy year-end.

Keep personal spending out of the business account entirely. If you take cash out for yourself, record it as drawings, not as stock. Mixing the two is the fastest way to make a straightforward set of books incomprehensible.

Step Three: Give Every Receipt a Home

Choose one place and stick to it. A monthly envelope works. A digital folder works better, because it can't be soaked in vinegar.

Sort for five minutes every Friday. Name files with the date first, then the supplier, so they land in order. Anything missing, faded or unsigned — ring the supplier that week and ask for a duplicate while your account is fresh in their system. Records generally need to be kept for several years, so confirm the exact retention period that applies to you with your accountant rather than guessing.

Step Four: Reconcile the Bank Every Week

Bank reconciliation sounds like a job for a suit. It is really just ticking off the statement against your records. Do it weekly, on a quiet morning before prep, and it takes fifteen minutes. Leave it for a year and it becomes a punishment.

1. Open the business bank account and take the closing balance.
2. Add any card or delivery payouts that haven't landed yet.
3. Subtract payments you've made that haven't cleared.
4. Match each line against your expense record — suppliers, wages, energy, card fees.
5. Flag anything you don't recognise immediately.

Weekly reconciliation catches duplicate supplier invoices, missed cash banking and card fees you didn't know existed. All three cost real money.

Step Five: Close the Month in Under an Hour

At the end of each month, total your sales by channel and your expenses by category. Add up cash taken versus cash banked. Then compare it with last month and ask three questions: did food cost drift up, is the card fee line growing, and did any category jump without a reason you can name?

Write a short paragraph of notes. Two or three lines is enough. Your accountant will read them, and so will you, twelve months from now, when you're trying to remember why March looked odd.

Pick the Simplest Tool You'll Actually Use

A spreadsheet with three tabs — Sales, Expenses, Bank — is enough for plenty of chip shops. Accounting software earns its keep when you're VAT registered, employing a team, or running more than one site, mainly because bank feeds and VAT returns save time.

If your till or EPOS system exports daily sales, use that export instead of retyping figures. Whatever you choose, the tool matters far less than the daily habit. A £20 spreadsheet used every night beats expensive software opened twice a year.

The Friday Night Test

If your system survives the busiest night of the week, it will survive anything. Keep the sales sheet by the till with a pen that works. Keep the receipt folder one tap away on your phone. Ten minutes a night in June is worth ten hours in January.

And when the numbers get complicated — VAT, staff, company structure, a big equipment purchase — pay an accountant for an hour of their time. On money and tax matters, a professional who can see your actual figures will always beat a general guide, including this one.
