How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Write the right reminder for how late the invoice is.

If the user gives only "client X hasn't paid", ask for amount and due date — nothing else is required.

Never apologize for asking.

If stage ≥ Firm: a 2-bullet note on what to prepare (contract clause, record of delivery) in case it escalates.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Invoice Follow-up
Write the right reminder for how late the invoice is. Tone escalates with time; the relationship is preserved until the last stage.
Inputs to collect
- Invoice number, amount, original due date, today's date
- Client contact name and whether there's an accounts-payable contact
- Any prior reminders already sent
- Payment terms / late-fee clause in the contract (if the user has one)
If the user gives only "client X hasn't paid", ask for amount and due date — nothing else is required.
Escalation ladder
Pick the stage from days overdue. Never skip stages unless the user asks.
| Days overdue | Stage | Tone | Length |
| −3 to 0 | Courtesy heads-up | Friendly, assumes it's in progress | 3 sentences |
| 1–7 | Reminder | Warm, factual, offers help | 4–5 sentences |
| 8–21 | Firm | Direct, states consequence (work pause), asks for a date | 5–6 sentences |
| 22–45 | Final notice | Formal, references terms, sets a hard deadline, late fee if contract allows | 6–8 sentences |
| 45+ | Pre-collections | Formal, states next action (collections / legal / platform dispute), no pleasantries | Short |
Rules for every stage
- Subject line contains invoice number and amount:
Invoice #1042 — €1,200 — [stage word] - First sentence states the fact (invoice, amount, due date). No "hope you're well" after stage 1.
- One clear ask with a date: "Can you confirm payment by Thursday 23 Oct?"
- Re-attach or re-link the invoice every time; assume it was lost.
- Offer the easiest payment path (link, IBAN) in the body.
- Never apologize for asking. Never threaten anything the user won't do.
- At Firm stage and later: pause-of-work sentence is mandatory — "I'll hold the remaining deliverables until this is settled."
- Late fees only if the contract has a clause; otherwise don't mention them.
Output
Return:
- The email (subject + body), ready to send.
- A one-line next check — the date to follow up again and which stage comes next.
- If stage ≥ Firm: a 2-bullet note on what to prepare (contract clause, record of delivery) in case it escalates.
