Odoo: Invoice Milestone

Why we need to use it?

Business case: in project management, invoices are issued usually according to project event - called milestone - which creates an invoice on a predefined % or amount. Such as Payment I : 30%, Payment II : 50%, Payment III : 20%. How to make it? How can we know how much % we already invoiced?

Odoo behavior: for service product, the invoice control can be done only on ordered quantity for 100%. It's not possible to plan the invoice based on a milestone validation and not east to simply invoice an order line in %.

Falinwa behavior: by adding the notion of invoice term, each sales order line can have the list of milestone and the milestone validation will automatically generate the related invoice.

  • So the answer is Invoice milestone by Falinwa. We can split the invoice, schedule it, and control the % invoiced

Complementary info on HTML:

Required access right to use the module: Analytic accounting and analytic accounting for sales.Before creating the invoice term, create the milestone products you will invoice.


Tips: if you test the module, you need to go in debug mode in Settings > Technical > Schedule Action >  Automatic generation of invoice from Milestone date and run it manually.
