The Recupel or Bebat Taxes are amounts included in the sale price of the products.

Those amounts are mostly computed based on fixed price.

The way to compute them in Odoo is by doing the following configuration:

1./ Taxes configuration:

Create as many taxes as needed (the fixed amount can vary from a few cents to several euros). Find in the following screenshot an example for an eco-taxe configuration

/!\ Check with your customer the accounting configuration if the amounts needs to be recorded on the accounting reports (balance sheet, P&L, tax reports).

2./ Taxe computation

The taxe should be applied before any other taxes (standard VAT Rates) so the field "Impacte la base des taxes ultérieures" should be True.

You can also apply a lowest sequence to all the eco-taxes so they are evaluated first.

Example:

Sale price = 100

Eco-Taxe = 0.3

VAT rate = 21%

=> Total amount = (100 + 0.3) * 1.21 = 121.36

Subtotal = 100

Taxes = 0.3 for eco-taxe & 21.6 for Standard Rate
