What to check before issuing
- Complete fiscal data: name, tax ID, address, correct bank account.
- The correct amount, matching the offer or signed contract.
- The payment term, clearly stated, not assumed.
- Series and numbering, consistent with the rest of your issued invoices.
A common mistake
Fiscal data copied manually, with a one-letter mistake in the tax ID, which forces a credit note and reissue, a much slower process than the initial 30-second check.
How to avoid repetitive manual checking
When client data is saved correctly once, every later invoice pulls it automatically, without retyping anything every time.
Bottom line
A short checklist, applied consistently, prevents most common billing mistakes, far cheaper than fixing them afterward.
