Invoice-System Compliance Guide
Compliance requires more than editing one template. You need a connected process across required fields, tax calculation, counterparty checks, and retention.
1. Cover Mandatory Elements
Turn mandatory requirements into a checklist and prevent omissions by process. Registration number, transaction date, details, and per-rate tax data should be checked during entry, not at final send.
2. Standardize Tax-by-Rate Display
For mixed-rate invoices, split taxable base and tax amount by each rate. Standardize formula and rounding so different operators get the same result.
3. Maintain a Registration Verification Flow
Do not stop at merely writing the number. Add a routine to verify current status and keep a log. Incorrect or outdated numbers can affect client-side processing.
4. Manage Retention and Reissue in One Flow
For compliant invoices, reissue traceability is critical. Keep old-new linkage, revision reason, and reissue date, and mark which version is effective.

How to handle changed or invalid registration numbers?
After verifying new status, update templates and reissue affected invoices if needed. Log change date and impacted invoice IDs for traceability.
Any PDF retention tips for compliant invoices?
