Hello,

after years of working in the « 1 purchase order = 1 invoice » scheme, a supplier just sent me one invoice for 2 purchase orders…

How do I deal with that ? What is the best process or module that makes it possible to concentrate several orders on one invoice ? And will it work if the invoices are already drafted in tryton ?

Thanks,

–  
Rémi

You can use the [purchase\_invoice\_line\_standalone](https://docs.tryton.org/projects/modules-purchase-invoice-line-standalone/en/latest/) module to generate the invoice lines and group them when receiving the invoice. (similar to what we do when reciving purchase moves)

hi, thanks a lot for that.

Now since I’m stuck in 6.4 I can’t choose supplier by supplier, but at least I can manage until [Add purchase invoice creation method (!287) · Merge requests · Tryton / Tryton · GitLab](https://foss.heptapod.net/tryton/tryton/-/merge_requests/287/) is released.
