We have a customer who wants to invoice all the shipments delivered in the months should be grouped into a single invoice at the end of the month. For this, we activated the sale_invoice_grouping module until we found the following case:
- A shipment for the customer was delivered into the first day of the next month
- The accountant did not post the invoice before the shipment was delivered
This resulted in a wrong grouping because the invoice included shipments of two months.
I’m wondering if it will make sense to have a “period based” invoice grouping method. The objective of this method is to group the invoices based on a date (shipment date when invoice method is shipment or sale date when invoice method is order). So in case there is a draft invoice same conditions but outside of the period another draft invoice is created.
I know there is a third party module which does more or less what I need, so it seems others also have the need of such feature. I’m wondering if we should have this as part of standard.
