French lettrage of open items
Letter codes A, B ... AA per partner and account, automatic and manual lettrage, partial lettrage, aged balance and an audit log
French accountants match receivable and payable items with letter codes. The module adds its own lettrage to journal items: each set of matched lines gets the next code of the partner and account (A, B ... Z, AA ...). Automatic lettrage takes what Odoo already reconciled, then pairs on reference and amount and tries small balanced combinations. You can letter selected lines by hand, undo a lettrage, check the balance of the codes and read an aged balance of what is still open. Every operation is logged.
Key features
Letter codes
Per partner and account: A to Z, then AA, AB ...; a set that does not balance yet is flagged as a partial lettrage on its lines.
Automatic lettrage
First the groups Odoo already reconciled, then same reference, same amount and balanced combinations up to the number of items you set, with amount and date tolerance.
Manual lettrage
Select lines of one partner and one reconcilable account and letter them; the cockpit shows the balance first.
Delettrage
Undo a code; the lines become open again and the operation is logged.
Balance check
Counts open items, partial codes and their residual per company.
Aged balance
Unlettered items per partner by age at a date, with a CSV export and a link to the items.
Audit log
Lettrage, delettrage and partial operations with user, lines and amount; log lines cannot be changed.
