Year-End Accounting Checklist
A year-end accounting checklist covers five stages: reconcile every account against external records, confirm every supplier invoice for the year is entered and filed, resolve every flagged or unclear invoice, review your VAT position across all periods, and hand your accountant a clean, complete set of books. The point is not to do the accountant’s work — it is to make sure they are not billing you to reconstruct a year of missing invoices.
Year-end is when the cost of skipping monthly bookkeeping shows up — usually as an accountant’s bill for reconstruction work that should never have been needed. The work at year-end is not harder than monthly bookkeeping; it is the same work, but compressed into a few weeks and harder to do because a year of small omissions has accumulated. This checklist is the minimum set of steps that turns year-end from a crisis into a review. Most of it can be done before the accountant is even involved.
Reconcile & verify
Reconcile every bank, card and payment account for the full year
A full-year reconciliation is the only reliable way to catch a missing invoice or an unrecorded fee that slipped through during the year. Doing it at year-end — rather than piecemeal — lets you see patterns, like a recurring fee no one noticed.
Confirm every supplier invoice from the year is entered and filed
The most common year-end problem is a stack of invoices that arrived but were never entered — found now, in a drawer or an inbox. Confirming completeness before the accountant starts means they work from a full set, not a partial one they have to hunt for.
Resolve every invoice flagged as unclear, duplicated or unmatched
Flagged invoices left unresolved at year-end become assumptions — the accountant enters something plausible and moves on. Resolving them yourself, while you still remember the context, is what keeps the books accurate.
Review & adjust
Review your VAT position across every period of the year
A year-wide VAT review catches errors that span periods — a rate applied wrongly for months, a credit carried forward incorrectly. Catching these at year-end is far cheaper than amending filed returns after the fact.
Check for accruals and prepayments that span the year boundary
An invoice for insurance or rent that spans two accounting periods needs to be split, or one period’s expenses are overstated and the next is understated. This is a standard year-end adjustment — and one of the most commonly missed.
Hand off to your accountant
Hand over a clean, reconciled set of books — not a shoebox of receipts
Accountants bill for the time they spend organizing your records, and that time is the most expensive part of a year-end engagement. A clean handoff means they spend their hours on tax planning and review — where their expertise actually pays you back — instead of data entry.
How Nika helps
Nika does not do your year-end. What she does is make sure that by the time year-end arrives, every supplier invoice from the year is already entered, flagged and filed — so the year-end checklist becomes a review of complete records, not a hunt for missing documents. The difference is measured in weeks of accountant time.
Questions
When should I start year-end preparation?
Start the reconciliation and invoice-completeness check at least four to six weeks before your accountant’s deadline. Starting earlier does not help much, because late-arriving invoices can still change the picture; starting later means paying rush rates or filing an extension for what was, in hindsight, an avoidable delay.
Can Nika help with year-end?
Nika does not prepare financial statements or file tax returns. What she does is ensure that throughout the year, every supplier invoice is entered and filed the day it arrives — so at year-end, the invoice side of the checklist is already done. Her role is prevention, not cleanup.
