More info...

Prevents the PDF of a validated customer invoice from being regenerated afterwards. On validated, paid and abandoned invoices, the module hides the “Generate” button and the template selection. Regeneration is also blocked on the server side. This keeps the PDF that was sent to the customer unchanged, supporting tamper-proof archiving (e.g. German GoBD). Draft invoices keep the button. The PDF created automatically on validation is not affected. The document list and all downloads remain available.

  • No configuration needed: just enable it
  • No changes to the Dolibarr core, built entirely on hooks
  • Requires Dolibarr 19 or later
