Tryton should be able to manage customer and supplier deposit. A deposit is an amount paid by the customer prior to the company providing it with services or goods.
A new kind of account "deposit" should be added to be used to compute the amount deposited by a party. It should be possible to invoice a product (service) with this kind of account. On an invoice, it should be possible to recall part of existing deposit in a line with a negative amount. When posting the invoice, it should never make the deposit amount of the party below zero. On sale, it should be possible to define a deposit plan which will create invoices with deposit. Next invoice will have deposit a negative line from the previous deposit invoices.

When deposit_amount is filled on processing a deposit invoice is created using the party customer deposit account. No shipment nor invoice will be created until the deposit invoice is paid. When an invoice is created, the deposit amount is recalled if it was not yet fully done. The amount of deposit is computed by looking at all invoice lines linked to the sale which has the same deposit account as the one created first.
