Year-end accounts preparation runs on receipts, and every accountant knows the same pattern: the client sends 80% of what is needed straight away, and the remaining 20% takes three follow-up emails and half a week to chase down. That last 20% is what actually delays the job.
A clear, specific checklist sent to clients well ahead of year end fixes most of this, not because clients are careless, but because most have never been told exactly what "send your receipts" means in practice. Vague instructions produce vague, incomplete responses. This is the checklist to send instead.
Why a generic reminder does not work
A reminder that says "please send your receipts and invoices for the year" gives a client almost no useful direction. They do not know if you mean every purchase or just the large ones, whether bank statements count, or what to do about a receipt they genuinely cannot find. Faced with that ambiguity, most clients send whatever is easiest to gather and hope it is enough, which it rarely is.
