Your AP clerk posts 35 vendor bills before month-end close. The auditor arrives five days later. Nine of those bills have no PDF attached. Someone spends two days digging through email threads and shared drives. Three source documents are never recovered.

Invoice Attachment Enforcer adds a posting gate inside Odoo. You pick which journals require at least one attached file before a bill or invoice can be confirmed. When a clerk tries to post without uploading anything, Odoo blocks the action and shows a clear message telling them exactly what to add. The clerk attaches the file and re-posts. Done.

Setup takes under five minutes per journal in Odoo settings. No developer, no custom code, no changes to user roles or permissions. Finance managers control which journals enforce the rule. AP and AR clerks handle the fix themselves without escalating to IT or their manager.

Teams that turn this on before their next audit stop scrambling for source documents at close. Document retrieval moves from a two-day fire drill after posting to a five-second step before it.
