With your wp2print, you can build a Private Store or customer portal for each of your large customers. This private store will contain the documents the customer orders recurrently, such as letterhead, business cards, brochures, and posters. Once a document is in the private store, any employee of that company, anywhere across the country, can order that document from you.
If your build a private store for your customer and the customer’s employees get used to ordering through the private store, then you make it extremely hard for a competitor to steal that customer’s business from you.
