These are Mobile Commerce products built by third parties which we support. They were revolutionary in their day and still provide much value at the price points.
Developing mobile commerce solutions can differ widely on a case-by-case basis, but we have found these well supported third party products that are the right fit for many mobile commerce applications.
We have built extensions on these products to cater to the local market which have saved many thousand of dollars compared to other mobile commerce solutions.
The classic use case is a travelling sales rep placing orders with customers on a business to business (B2B) relationship. The B2B Mobile App ordering system can be integrated with many systems and payments can be made in more traditional ways (over the phone, bank transfer).
Similarly a Retail Sales App is available although there are many compelling solutions in the market today for only commerce. These products fit the personal trainer, business coach and other similar occupations because of the ability to link an appointment booking system with calendar integration.
