AI prompts to try

Copy one of these into ChatGPT, Claude or your AI tool of choice and adapt it to your situation.

Drafting client onboarding
“Write a professional, friendly onboarding email for a new UK sole trader client. Ask them to grant me 'Standard User' access to their Xero account and authorize the bank feeds. Include a bulleted list of what I need from them (e.g., last year's accounts, payroll details).”
Explaining jargon to clients
“I need to explain to a non-financial UK client why their 'Profit & Loss' doesn't match their bank balance. Explain the difference between cash and accrual accounting in simple, friendly terms using a real-world analogy.”
Creating SOPs
“Create a step-by-step Standard Operating Procedure (SOP) for doing month-end bank reconciliations in Xero.”
