The interface is very easy to navigate when it comes to creating new features/shops etc but also allows you to customize as much or little as needed! I have yet been able figure out how to print invoices which can be frustrating at times with this software because there are so many different options that sometimes don't work together well (or ever). This would take some learning time however once figured out makes things super straight forward in regards to printing invoice after order process flow. Great app if someone has no experience using point of sale systems like zenpay or similar apps. We've had great success implementing this into our store and allowing customers to pay their bill through mobile device instead of having them walk up to cash register to do same thing. Not only does it save us money each month due to reduction in tips we receive per hour worked compared to traditional POS methods, but it's just easier overall for customer service purposes too.
