Most Sage 50 businesses already know the problem: the representative is with the customer, the customer wants to order, and the live account, price and stock sit back in the office.
Remote desktop into Sage is one answer. It is also the wrong one for field sales. A salesperson does not need the accounts application. They need a short, reliable visit workflow: select the customer, see the price that belongs to that account, check stock, enter the order, and let Sage receive it.
What field sales actually needs from Sage 50
The Barcoder Mobile Sales App takes Sage 50 customer, pricing, stock and order information out of the office and puts it on the tablet. Completed orders synchronise back into Sage 50.
That is a different job from giving someone Sage 50 itself. The tablet is built around the visit, including when there is no signal.
