Common fiscalisation errors and how to fix them

Most fiscalisation errors fall into a few buckets. Here's how to recognise and clear each.

The usual errors

• Missing / invalid HS code — a line has no valid 4- or 8-digit code. Add one and re-fiscalise.
• Tax selection required — a line has no tax class. Set standard / zero / exempt on the line.
• Fiscal day not open — open the day on the device, then re-issue.
• Device not registered — finish device registration first (check the details match ZIMRA).
• Sequence / signature error — the counter or hash chain is out of step; let PI Fiscal re-align and resubmit (see its own article).
• Buyer TIN required — a B2B document needs the buyer's name and TIN.

General approach

1. Read the exact message — it names the field or line at fault.
2. Fix that line/field only; don't start a new document for the same sale.
3. Re-fiscalise. If it persists, raise a ticket with the error code and device.
