We customise our software to suit different clients invoice approval methodology. We have a 37 page Visio diagram that shows the path the invoice takes for approval. We require a person(s) to process a set of invoices through the solution as per the flow in the Visio and to document if the invoice does not flow as per the diagram. The solution is web based. We also require documentation on how to test the solution so we may provide it to our clients.
