Terrible reporting, dead support links. Pro has no refund policy.

No way to cash up or export any sort of end-of-day report. Makes the idea of POS pretty redundant for almost any brick-and-mortar trader.

Refund policy on their site for the pro version states they “generally don’t give out refunds”
The documentation is outdated.
The Demo only shows you a registerPOS preview, not the rest of plugin functionality (which is severely lacking even with pro payments)
The roadmap on their site holds no details and is not kept up to date.
Several support links on their site don’t work, and contact forms return errors.
