I need to find out the best way for my client to be able to allow their suppliers access to their system so that the suppliers can upload invoices. We are thinking of creating a stand alone Suppliers system and host it on the clients server along side their current FM solution. Then allow the suppliers access to the Suppliers system so that they can upload invoices, then when they are done I will create a script to push the relevant information to the correct tables in the Main FM system.
I am just worried about things like security and if WebDirect would be the best option for this. My client has just under 600 supplier accounts currently on their system, but of that there are probably only about 250 which are currently active and the chance of more than 10 login on at the same time to upload invoices would be very rare.
What pitfalls am I getting myself into?
