When you first run CustomerOrders, it will ask if you wish to import products and customers from other applications, you can either import then or at anytime in the future. Simply export the data from your other applications as a comma separated value (.CSV) file; you can then import into CustomerOrders.
We recommend you first import your customer details, for example their company name, address and contact details. You can then import your products (names, descriptions, price). If the customer name and details matches exactly a customer already in the database it will not be added, if not the program will create a new customer.
