Purchasing, stock and sales sit in separate spreadsheets; stock is checked by calling the warehouse, and customer debts live in the bookkeeper’s notebook. maERP links the purchase order, the receipt, the sale and the customer’s debt into one chain of documents.

Wholesale and retail in one database: the shop till and the delivery note draw down the same stock.
