Having purchased 2.3, I would like to request 2 important features:
1. Our current invoicing "system" gives each client a unique code rather than an identity int or GUID. This code is for business purposes. Is it possible to add a field inot the table and editing of the client such that this client code is used rather than the clients id.
2. The ability to make a line on an invoice as a credit. Ie. give it a negatvie cost. This would make it easy for an overpayment to be treated as a credit note.
Thanks.
