Unique Reference Enforcement

One reference, one document. Duplicates get blocked before they cause damage.

Duplicate vendor references lead to double payments. Duplicate customer references break reconciliation. Odoo warns about some of these but does not stop them. This module enforces uniqueness properly, with clear error messages for users and real database indexes underneath, so nothing gets through, not even imports or API calls.

What gets protected

Document Field enforced
Sale OrderCustomer Reference
Purchase OrderVendor Reference
Customer Invoice / Credit NoteNumber
Vendor Bill / RefundReference
PaymentMemo

Two layers of defence

Form-level checks give users a clear message the moment they save a duplicate. PostgreSQL unique indexes catch anything that bypasses the form.

Case and space proof

INV-001, inv-001 and " INV-001 " count as the same reference. No sneaky duplicates through formatting.

Per-company scope

Each company keeps its own reference space. Multi-company databases work exactly as you would expect.

Safe install and uninstall

Before installing, your database is scanned for existing duplicates so you can clean them first. Uninstalling removes the indexes cleanly.
