Christmas Cash Flow Checklist for UK Small Businesses

Christmas can be the best trading period of your year. It can also be the point where a profitable business runs out of cash. Sales rise, then bank holidays slow payments, while wages, stock and VAT keep coming. A short checklist in early December keeps the festive season profitable and the new year calm. The aim is not to predict everything perfectly. It is to avoid surprises. Work through the steps below and adapt them to your trade.

Start with a festive cash flow forecast

Build a simple weekly forecast from now until early February. List money in: card takings, cash, bank transfers, deposits and expected invoice payments. List money out: stock, wages, rent, utilities, loan repayments, VAT and PAYE. Include your own drawings or salary. If you pay yourself monthly, do not forget it. Run three versions: quiet, busy and likely. Update it every Friday.

Check dates, not just totals. A payment due on 20 December is very different from one due on 3 January. If software gives you debtor and creditor reports, use them, but confirm the timing with a phone call for any large sums. If a big invoice is due, ask the customer to confirm the payment date in writing.

Know your breakeven week

Work out the minimum weekly takings needed to cover essential costs. If orders fall below that line, act early: pause a stock order, cut temporary hours, or move a supplier payment. That number is your early warning system. Review it after the first week of December.

Stock: buy enough, not too much

Seasonal stock ties up cash. Order too little and you lose sales; order too much and you fund the January sales. Use last year's figures, current pre-orders and your forecast. Check supplier lead times and courier cut-off dates now. For high-value items, take a deposit or full payment at order. Check storage space before ordering. A garage full of stock is cash you cannot spend. If you sell online, confirm the last dispatch date you can meet.

• Review last year's best and worst sellers.
• Set a reorder trigger for key lines.
• Clear old stock before Christmas with a bundle or small discount.
• Confirm your returns policy and who pays return postage.
• Keep a small contingency for a late bestseller.

Staff: pay, rota and hidden costs

If your normal payday falls on a bank holiday, staff will expect paying early. Find that money now. Budget for overtime, temporary staff, agency fees, employer National Insurance and pension contributions. Check holiday requests before publishing the rota. Match hours to footfall instead of adding blanket cover. Offer time off in lieu where your team agrees. Do not promise a bonus you cannot afford in January. If you use temporary staff, check who handles payroll, right-to-work checks and induction. For contracts, holiday pay or dismissal questions, take advice from an HR or legal professional.

VAT and taxes: set the money aside

Tax does not stop for Christmas. If your VAT quarter ends in December or January, the payment follows soon after. Move the VAT element of each sale into a separate account as it arrives. Keep the tax money separate so it does not get spent on stock. Do the same for PAYE and National Insurance. If you file self assessment online, 31 January is the deadline for the return and any payment due. Corporation tax is usually due nine months and one day after your accounting period ends. Missing deadlines adds interest and penalties. If cash is tight, contact HMRC before the due date to discuss a payment plan. An accountant can confirm what is due and when.

Customer payments: chase before the break

A sale is not cash until the money reaches your bank. Send statements early. Call anyone already late. Confirm bank details verbally before sending large payment requests, because invoice fraud rises when offices are quiet. Set credit limits for new customers and stick to them. Ask for deposits on large orders. Check that card and online payment providers will settle funds over the bank holidays. For online sales, test your checkout and delivery notifications before peak trading. If an invoice is disputed, deal with it now. An unresolved query becomes a January bad debt.

1. List every unpaid invoice.
2. Send a polite reminder with the invoice attached.
3. Call anyone more than 14 days late.
4. Agree a written payment date for each overdue account.
5. Pause work or stock for customers who will not commit.
6. Check your bank account daily between Christmas and New Year.

If a customer asks for extended terms, be careful. They are asking you to fund their Christmas. You can agree, but ask for a deposit, a post-dated payment or a smaller order. Put it in writing.

Suppliers, overheads and final checks

Talk to main suppliers before the break. Confirm opening hours, payment runs and delivery dates. If a payment will be difficult, ask to move the date rather than missing it. Ask suppliers for a January payment date now, while they are still planning. Review recurring costs: unused subscriptions, insurance renewals, energy contracts and software seats. Check rent, service charge and insurance payment dates. Pause anything that will not earn its keep in January. Keep a cash buffer for emergencies. A failed fridge or card machine costs more when everyone else is closed.

Your one-page Christmas cash flow plan

Write a single page and pin it up. Show money due in, money going out, who chases debts, and who can authorise an emergency payment. Reconcile your bank account before the break. Download statements and save them where you can access them remotely. Set an out-of-office reply with an urgent contact number. Schedule online payments so nobody has to remember to log in on 27 December. Check insurance cover for seasonal stock and temporary staff. Give your accountant a copy of the plan and any payment arrangements. Then rest. A proper break helps you make better decisions in January. If your tax or legal position is complicated, speak to an accountant or solicitor before the new year.
