+
+Suppliers often grant a discount when their bills are paid within a few
+days, and many of them settle it with a credit note of their own that
+reaches the company weeks later, if ever. This module keeps that
+discount on the supplier and on its bills, takes it when the bill is
+paid in time, and follows up the credit note the supplier owes.
+
+- **Early payment terms on the supplier**: up to two chained discounts,
+  the days to pay within, and whether they count from the invoice date
+  or from the receipt of the goods.
+- **On the vendor bill**: the last day to pay to earn the discount and
+  what the discount takes off.
+- **Apply Early Payment**: posts an internal credit note for the
+  discount and reconciles it with the bill, so what is left to pay is
+  the net amount.
+- **Follow-up**: the internal credit note raises a to-do for the *Early
+  Payment Credit Notes* activity team, made of the users of the *Follow
+  Up Early Payment Credit Notes* group, until the credit note of the
+  supplier arrives.
+
+The native early payment discount of the payment terms does not fit this
+flow: it knows a single discount counted from the invoice date and books
+it as a write-off when the payment is registered. Here there are two
+chained discounts, a base on the receipt date, a credit note because the
+supplier issues one, and someone chasing it.
+
+**Table of contents**

+
+Configuration
+=============
+
+- Open a supplier, *Sales & Purchase* tab, *Early Payment* group: fill
+  in the discount percentages, the days and whether they count from the
+  invoice or from the receipt.
+- Add the users who chase the credit notes of the suppliers to the group
+  *Follow Up Early Payment Credit Notes* (accounting managers have it by
+  default). They form the *Early Payment Credit Notes* activity team,
+  synced every time a credit note is chased.
+
+Usage
+=====
+
+A posted vendor bill of a supplier with early payment terms shows the
+last day to pay and the discount. Press *Apply Early Payment*: an
+internal credit note for the discount is posted and reconciled with the
+bill, and a to-do for the credit note the supplier owes goes to the
+follow-up team, on that internal credit note. Close it when the credit
+note of the supplier arrives.
+
+The business day the discount is paid on is exposed through
+``account.move._early_payment_pay_date()``: the early payment date
+itself, or the business day before when it falls on a weekend or a
+holiday of the working calendar of the company. Payment order
+integration lives in ``account_payment_order_early_payment_discount``
+(OCA/bank-payment).
