We require an e-procurement system.
The solution will allow for the online purchase of products. Products will be listed and admin will have command of them as normal for an e-commerce system.
On the admin side the solution will allow users to create an account. Clients will access their account through a password protected system and be able to view history of purchases. Purchase will be made through either a direct credit card transaction with payment gateway (e.g. paypal) or if the client is awarded an account they will be allowed goods shipped on credit (specified by admin) and will be invoiced automatically after a period which admin specifies.
The client currently uses Sage Line 50 for accountancy and so if possible the solution should be able to talk to this so that accountacy is streamlined.
I need a full list of experience from potential providers. No novices.
