Postpaid and Credit limit options for client

الطلب

In clients list, I should be able to click a client and set him/her as a postpaid client or a postpaid client with credit limit Postpaid client - he can order even with 0 account balance automatically or with my intervention (manual credit payment or product activation) Postpaid client with credit limit - he can order even with 0 account balance but up to a limit I set like $100 Of course if I dont credit the payment after a set time like 1 month, his product or service will be suspended.
