One of our clients called Earth Tech commissioned an Invoice Tracking System to handle the approval of invoices from their suppliers. All project invoices needed to go through a three stage system of (i) order matching (ii) material received on site and (iii) payment approval.
This process had been done manually in the past and often resulted in delays with invoices sitting on someone's desk outside of Finance control. We proposed scanning invoices and developing a system to handle the approval workflow. Tight integration with the Finance System allowed the whole process to be made more efficient.
This system was written for the Lotus Notes client. It could also have been written for a browser. It interfaced with the Sun Accounts Finance System. It could have been written for other Finance Systems.
