Chase missing client records before the deadline
"It's November, and half my clients still haven't sent their bank statements."
Last checked: 16 October 2026
Short answer
Our pick: ChatGPT. Free plan is enough to start. Draft a polite, then firm, 3-email chasing sequence once, then save it as templates in the email or practice software you already use.
Time to a ready-to-send sequence: about 10 minutes.
Copy this prompt
Write a 3-email reminder sequence from [practice name] to a client who hasn't sent [missing records] needed for [task] due [deadline]. Email 1 (sent [date]): friendly; lists exactly what's needed and how to send it ([portal]). Email 2 (+7 days): shorter; offers a 10-minute call. Email 3 (+14 days): firm; explains we can't complete [task] without them and that late filing can lead to HMRC penalties; states our cut-off date [date]. Use [CLIENT_FIRST_NAME] placeholders, British English, under 120 words each, no jargon.
UK note (GDPR): use placeholders. Never paste client names alongside UTRs, NI numbers or bank details into an AI tool; merge the real details in your own system.
Worked example result (dummy data). Illustrative example: written by us, not a recorded AI output
Hartley & Co, a 4-person practice in Chester, needs April–October bank statements and fuel receipts from sole-trader clients for the 31 January Self Assessment deadline:
- 1 Nov: a friendly checklist and a portal link
- 8 Nov: a short nudge offering a quick call
- 15 Nov: firm, with the practice's internal cut-off of 1 December and the penalty facts below
The late-filing figures quoted in email 3 come straight from GOV.UK: £100 at first; after 3 months, £10 a day up to £900; after 6 months, 5% of the tax due or £300, whichever is greater; after 12 months, another 5% or £300. Late payment costs 5% of the unpaid tax at 30 days, 6 months and 12 months, plus interest (https://www.gov.uk/self-assessment-tax-returns/penalties, checked 16 Oct 2026, re-checked 05:40 BST).

[Copy] button on this block (required).
Write a friendly welcome email from [practice name] to a new [sole trader / limited company] client. Include: a short "what happens next" list; a checklist of what we need ([e.g. photo ID and proof of address for our identity checks, UTR, last year's tax return, bank statement access, accounting software invite]); how to send it securely ([portal]), never by plain email; who their contact is; and our fee and engagement letter ([link]). Under 200 words, British English, use [CLIENT_FIRST_NAME].
Your identity-check requirements come from your supervisory body; this prompt only drafts the email.
