The trading plugin

The plugin adds functionality for managing sale, purchase or other kind of trading activity with named things (e.g. “products”, “services”).

Table of contents:


trade voucher

A ledger voucher that has a partner as recipient and one or several “rows” (“items”), each of which can refer to a product.

product invoice

An legal document that describes that something (the invoice items) has been sold to a given business partner (called the customer). The partner can be either a private person or an organization.


This plugin requires the products contacts and the accounting plugin.
