This is managed via Payment Terms.
Payment terms determine the due dates for paying an invoice.
To view existing terms or create your own, use the menu sequence
Accounting -> Configuration -> Miscellaneous -> Payment Terms
. . . when logged in as a user who has Technical Features checked on the Access Rights tab of their user record.
By default, OpenERP provides the following Payment Terms:
- 15 Days
- 30 Days End of Month
- 30 Net Days
- 30% Advance End 30 Days
- Immediate Payment
To configure new terms, start by giving it a name via the Payment Term field. The text you in the below is used on invoices, so enter a description of the payment terms for your Suppliers there.
Then create individual lines for calculating how the terms work under Computation. Each line has a Computation Type.
- Percent : this allows for a percentage of the total amount to be paid within X days.
- Fixed Amount : this is a fixed value given by the Value Amount box within X days.
- Balance : indicates the balance within X days (this would be your last line if you use either of the first options, if used by itself it is the total balance).
X is calculated from the values of Number of Days and Day of the Month. Hover over each to read a description of how they work.
You can set a default Payment Term for each Supplier, so invoices will default to honor that arrangement when created, and you can also can set Payment Terms for individual Supplier Invoices. You review/set this on the Other Info tab during Invoice creation.
