Eight Weeks to Go: A Practical Invoice-Chasing Plan for UK Suppliers Before Christmas

With eight weeks between 7 November 2026 and the first payroll of January 2027, UK suppliers still have room to change the outcome of the year-end cash cycle. The task is not to send more reminders. It is to send the right reminders, to the right person, at the right point in the customer's payment run — and to use the accounting calendar as a polite reason to confirm dates rather than as a threat.

Christmas Day falls on Friday 25 December 2026, with the substitute bank holiday for Boxing Day on Monday 28 December. Many finance functions will be thin from 24 December and will not return to normal until the first week of January. That makes the weeks beginning 9 November and 16 November the most valuable in the entire period. Everything after that is follow-up.

Week 1, commencing 9 November: audit before you chase

Start with an aged debtor report, but do not stop at the total. Build a list of every invoice that is already overdue, every invoice due before 18 December, and every invoice that will fall due between Christmas and the first January payroll. For each, record the customer, amount, invoice date, due date, purchase order or approval reference, the named contact and the last communication.

Then check the invoice itself. A missing purchase order number, the wrong legal entity, an outdated bank detail or a VAT error can add days to a payment run. Correcting those defects now is cheaper than arguing about them in December. Rank the list by value and by risk: large invoices, customers with a history of slow payment, and anyone showing signs of financial stress should be at the top. A statement of account should be prepared for every customer with more than one open invoice.

Week 2, commencing 16 November: first reminder and telephone call

Send a short, specific reminder by email, then telephone the largest accounts. Ask three questions: has the invoice been received, has it been approved, and on which payment run will it be paid? A promise of 'soon' is not a payment date. Ask for a date and, where possible, the name of the person authorising it. For customers using supplier portals, confirm that the invoice has been uploaded and accepted, and keep a screenshot or reference number.

The tone should remain commercial rather than accusatory. The purpose of this stage is to expose any administrative blockage while there is still time to fix it. If a customer says the invoice is disputed, ask for the specific point of dispute in writing and isolate the undisputed balance. A partial payment now is better than a full argument in January.

Week 3, commencing 23 November: build the escalation ladder

By this point, polite reminders should give way to a more structured approach. A letter or email from a credit controller or finance director, copying the account manager, can restate the due date, attach a statement and ask for confirmation of the December payment run. This is also the point to use year-end accounting deadlines as a practical prompt: ask whether the invoice is scheduled in the customer's December close and whether a cleaner statement of account would help their ledger reconciliation.

That is leverage, not menace. Do not imply a tax consequence that does not exist, and do not suggest that payment before 31 December will achieve something it will not. The aim is simply to make the invoice visible to the people closing the books.

Week 4, commencing 30 November: confirm December payment runs

Ask each significant customer for its December payment cut-off dates and the date on which approved invoices will be paid. If a credit note is required, issue it now. If a purchase order is missing, obtain it now. If the customer's finance team needs a revised invoice, send it the same day. Administrative tidiness at this stage is worth more than another strongly worded email.

For larger customers, ask whether the account is on stop or under review. If it is, find out what is needed to release it. A supplier that discovers a blocked account on 20 December has very little time to respond.

Week 5, commencing 7 December: final pre-Christmas push

For invoices due before 25 December, confirm bank details and the expected payment date in writing. For invoices due after Christmas, ask whether early settlement is possible; if it is not, record the January date and plan around it. Suspend further work only after checking the contract and taking advice. An abrupt withdrawal of services can damage your commercial position and may not be permitted by the terms already agreed.

This is also the week to prepare a cash forecast for the first payroll of January. Include PAYE, pension contributions, rent, VAT and any supplier payments that cannot be deferred. Identify which commitments can be funded from reserves and which depend on specific customers paying. That forecast will determine how hard you push in the final fortnight.

Week 6, commencing 14 December: close the loop before the shutdown

Issue final statements as of 18 December. Confirm in writing which invoices are scheduled for payment before the holiday and which will be paid in January. Prepare any escalation letters now, but schedule them for 4 January rather than sending them into an empty office. If a payment was promised for 24 December and does not arrive, keep a record and follow up in the first working week of January.

The awkward gap between Christmas and New Year

Between 24 December and 1 January, expect little substantive progress. Monitor the bank account, but do not interpret silence as refusal. Many finance teams are closed, and many payment runs are pre-loaded before the holiday. Use the quieter days to reconcile receipts, update the aged debtor report and prepare the January chase list. A brief email on 29 or 30 December may be appropriate for a critical payment, but it should ask for confirmation rather than reopen a negotiation.

The first payroll of January

From 4 January, move quickly. Send formal demands to anyone who missed a confirmed date, calculate statutory interest where appropriate, and set a short deadline for payment. If the debt is undisputed and the customer remains silent, a letter before action and a claim through Money Claim Online may be the next step. Where insolvency is a concern, take advice early and preserve evidence of the debt.

If February arrives and the money has not

Do not let embarrassment turn into a write-off. Escalate to a solicitor or licensed debt recovery agent, review any credit insurance, and consider whether continued supply is sensible. At the same time, review the terms and onboarding checks that allowed the problem to develop. The Christmas cash crunch is partly a calendar problem, but it is also a credit management problem. Suppliers that treat the final eight weeks as a structured collection cycle rather than a seasonal scramble enter January with more cash, clearer information and fewer unpleasant surprises.
