Why do you require a software subscription rather than a one-time fee for NRG's Shipping Software?
With our shipping software, we moved away from a one-time fee to a monthly to an annual subscription because of our commitment to maintain compliance with the carriers, Ecommerce providers and Mac software applications that we integrate with. FileMaker products are charged a one time license fee + the subscription.
Over the years we have released significant updates to the products, some because of the carriers changes or new services offered, and some due to hardware (Apple's move to new processors) which require extensive development resources and carrier re-certification.
There are many other shipping software vendors who follow a similar pricing model to NRG and we believe it makes the most sense for our products and customers, allowing us to consistently provide updates to keep you shipping.
Note: Our subscription pricing was implemented in 2008. Customers who paid for software prior to 2008 and want to upgrade may do so by going on the monthly or annual subscription for their product.
