Tips that actually work
- Send the first one before the due date. Most "late" invoices were simply forgotten. A heads-up three days before fixes half of them.
- Always include how to pay. A link beats "see attached".
- Keep the tone level. Firm is fine; angry costs you the next project.
- Ask a question. "When can I expect payment?" gets replies. Statements get ignored.
- Stop the moment they pay. Nothing is more awkward than a reminder after the money landed.
