EDI helps you in different ways.
First by saving labor - manual transactions take your employees’ time for order entry, phone calls, and faxes. Compared to paying employee salaries to do repetitive tasks, EDI is cheap. EDI can reduce the amount of labor per shipment significantly.
Also, EDI ties you to your customers and vendors together. If you are a 3PL, EDI helps you scale your business and serve multiple customers. If you are a shipper, you don’t need to pay employees to contact your vendors to route shipments. EDI also reduces data-entry errors, which is valuable.
