I do not know about the detail yet, however,
I could provide a viewing sheets just four your needs. Also, I am thinking about writing an application to connect to your Access Database, if you do not have it yet. This application will
make it easier for you to track order history,
goods status (where it come from, when, why is it order, what PO it belongs to, etc), what's left, where it'll be sent, is the payment received yet. Basically to make you control the business process with ease. Thank you, looking forward to hear from you again.
