In December, not February. Most items on the list are easier before the year closes - requesting a document from a supplier, collecting a balance, cancelling a subscription. What is left for February is what genuinely has to happen after year end.

What gets forgotten most?

Expenses never captured and reconciliations never done. Together those explain almost every gap found at closing, and both are prevented by a monthly routine. If you reconciled every month, closing is a check rather than a project.

Do I need to count stock?

In a business managing stock, a year-end count is part of the picture - and what exactly is required and how is a question for your accountant. Operationally, count before year end rather than after, and record the count with a date and who counted.

What about a balance that probably will not be collected?

First, decide - keep collecting, reach an arrangement, or stop. The decision itself matters more than its direction, because a balance left open with no decision contaminates next year's debtors report. The accounting treatment is settled with your accountant.

Year-End Closing: The Business's Operational Checklist

What a business collects and reconciles before year-end closing: missing documents, reconciliations, open balances, stock and suppliers. Operational, not reporting.

Year-end closing looks like the accountant's task, and most of the work in it is actually operational: confirming every document exists, that reconciliations were done, and that whatever is open is known and explained. This checklist is what the business does - not the reporting itself.

This is an operational description, not advice. What reporting and accounting closure require is settled with your accountant or tax adviser and the official authority pages.

The checklist, by area

Area	What to check	The sign something is missing
Income documents	All documents in the system, continuous numbering	A gap in the sequence, or a remembered manual document
Expenses	All receipts captured	A month with fewer expenses than usual
Bank	Reconciled through year end	A balance that does not match
Clearing	Reports for every month	An unexplained cumulative gap
Customer balances	Who owes and what their state is	An old balance nobody chased
Supplier balances	What is still unpaid	A forgotten invoice
Stock, where relevant	A count at year end	A gap against the records
Contracts and agreements	What was signed this year	An agreement that exists and was never handed over

The fifth row produces the surprises: a balance from eight months ago nobody chased is both money that never arrived and a question at closing.

What do you do in December?

Review the document list and confirm sequence and completeness.
Close gaps in expense capture - request copies of what is missing.
Complete reconciliations of bank and clearing through the last month.
Review the debtors report and decide what to collect, what to defer, and what is no longer realistic.
Check recurring payments and cancel what is no longer used.
Count stock, where relevant.
Gather the year's exceptional documents - a large purchase, an agreement, a structural change.

Step four pays best: it brings money back, and it also cleans the report presented at closing.

What is better done before year end than after

Requesting missing documents from suppliers - easier in December than in February.
Settling small balances not worth dragging into next year.
Cancelling unused subscriptions, so they do not renew automatically.
Confirming the system is ready for next year - numbering, dates, settings.

The last item prevents the early-January problem, when it turns out somebody has to change a setting by hand - covered in invoice numbering and series control.

What to hand to your accountant

That depends on what was agreed, so it is worth asking once and working to the answer. What is true in any case: hand it over in one organised go rather than in three rounds. The routine monthly list is in what your accountant needs each month, and at closing the year's exceptional documents and the stock count usually join it.

What this gives the business beyond closing

A true picture of the year - what came in, what went out, what is open.
Cleared balances that dragged for months.
Discovery of forgotten costs - a subscription, a service, a supplier who raised a price.
A basis for planning - what to price differently, and what to stop.

The first three are by-products of closing; the fourth is the real reason to do it properly rather than as a chore.

The mistake that repeats every year

The common mistake is starting the close in February, after the year has already ended. By then every supplier request is a reminder about something old, every balance is last year's balance, and every subscription cancellation arrives after it has already renewed for another year. The same work in December is simply work; in February it is work with interest. It also explains why businesses that start early describe their close as "easy" - not because they do less, but because they do it while things are still moving.

What to keep from the closed year

At the end of the process, export and store in one place: the year's income and expense report, the debtors report as it stood on 31 December, the clearing reports for every month, and the stock count if one was taken. Those four are the picture of the year, and they are what you will want to compare against next year. They are also hard to reconstruct later, because reports change as data updates - which is why the moment to save them is now.

Who does what at closing

An unclear division of work is what makes things fall between the cracks. Three questions worth settling in November:

Who collects the missing documents - usually whoever manages the folder.
Who does the reconciliations - the business or the accountant, and it varies.
Who reviews the debtors report and decides - a commercial decision, not an accounting one.

The third is the only one only the owner can do, which is also why it tends to be deferred. It is worth putting time in the calendar for it.

Why this is easier in a business that works continuously

A business that captures expenses in real time, reconciles monthly and sends material to its accountant continuously reaches closing with a short list: exceptional documents, a stock count, and decisions on balances. A business that defers everything reaches the same point with a whole year to unpick. The same work, except in the first case it is already done - and that is the real reason the monthly routine pays, even when it looks unnecessary at the time.

What to check ahead of next year

Closing is also the natural moment to look forward. Four short checks: whether the price list is still right, or suppliers raised prices and you did not; whether any customers have become unprofitable; whether there is a service or subscription you can drop; and whether the systems still fit the size of the business. Those four questions take half an hour, and they are exactly what is hard to do mid-year when everything is running. The answers are usually worth more than the closing itself.
