Retention and Advance Payment

Contracting and project invoices withhold a retention and net off advances already paid. This module adds retention and down payment percentages to invoices and posts each amount on the partner configured accounts. The partner form shows the balances. It is used by accountants and project billing staff and plugs into Accounting and the products provided by the retention data module.
