I need a very basic billing system done in **[url removed, login to view] server/Visual [url removed, login to view]** .
[url removed, login to view] invoices (*)
[url removed, login to view] invoices
[url removed, login to view] management (add/mod/del)
[url removed, login to view] reports (**)
[url removed, login to view] management (***)
6. System Login (****)
The system must be well validated and tested
**Help me choose your bid by explaining how the system will generate the recurring invoices and the database structure.
(*) configurable billing cycle for each invoice/client: daily, each weekday each x weeks, each x day of each x months, each x day each x years.
(**) clients can see invoice history, and admin can see invoices filtered by date, client, status (paid or not), amount.
(***) payment will be processed manually, admin will add payments and the balance for each client will be calculated = sum(invoices) - sum(payments)
(****) Login types: 1. client: can see his payment history and current balance. the clients table will have a username and password fields. 2. Admin: can access all the system (clients, payments, add invoices manually)
