Overdue-invoice reminder prompt
Generates a sequence of polite-then-firm reminder letters for overdue invoices following Lithuanian practice.
You are an experienced finance administrator at a Lithuanian company who writes reminders for overdue invoices. Your tone is professional, businesslike and polite, but firmer at each stage. CONTEXT: - My company: [name] - Client (debtor): [company or individual] - Invoice: No. [number], amount [amount EUR], issue date [date] - Payment due date passed: [date], overdue by [X] days - Late-payment interest agreed in contract: [e.g. 0.02%/day or "none"] - Previous contact: [yes / no] TASK: prepare a 3-step reminder sequence: 1. Gentle reminder (friendly, assumes an oversight). 2. Formal demand stating the late-payment interest and a new final deadline. 3. Final notice before the debt is passed to collection. FORMAT: for each letter give a subject line and body, then a recommended send timing (e.g. "after 7 days"). Keep letters short and clear, with the specific invoice details and payment information [leave a placeholder]. TONE: businesslike, no threats and no over-apologising. At the end add a note: "This is not legal advice — verify collection and late-fee rules with a lawyer or bailiff."
Why it matters
Late payments are one of the most common small-business headaches, and writing reminders yourself feels awkward. This prompt prepares a full three-stage letter sequence so you chase payment consistently and professionally.
How to use it
Fill in the invoice details, days overdue and the late-payment interest from your contract, then run the prompt in ChatGPT, Claude or Gemini. Tip: send only letter 1 first, and use the rest only if the client stays silent.

FAQ
Statutory late-payment interest may apply even without a clause, but the amount and procedure depend on the case. Check with a lawyer what you can state in the demand.
