As each despatch note and purchase receipt is raised, its details are passed to the History module, which allows your staff to examine past sales and purchase records instantly.
For example, if a customer calls to raise an order and asks how much they paid last time, the information can be recalled with just a few clicks. No need to search the filing cabinets.
Herschel also records all purchase receipts and stock movements in a similar, easy to search format.
All history is held for ever.
