The simplicity of use and the customer service is brilliant. Never had a issue with them not being available.
The system is great to set top and the stock control is really impressive.
After you set up your products and storage areas, the ease of use for tracking inventory is awesome.
The very poor smartphone app - forces us to use laptops for stock counting etc. The poor response time to errors in the system - developers have taken months and to date issues are still not resolved.
We have problems when stock or sales do not sync properly or on time.
The next issue to tackle is the Database and how it gets filtered in some specific instances. No major issues to complain about though.
