What a good contract number does
It helps you and your customer reference the same document quickly and prevents duplicates.
A simple format that works
- Prefix (e.g. **AGR**) + date + sequence: `AGR-YYYYMMDD-001`
Tips
- Keep it short; avoid spaces.
- Use the signing date (or document creation date) consistently.
- Don’t embed confidential info in IDs.
Why it matters for payments
Your payment link, receipt, and invoice should reference the same number to reduce finance back-and-forth.
