We have been using this module in our business since last 2 years with many number of customers that we are serving from different geographies. It's very easy to configure & integrate with various EMs (like AP, CC, Debit Cards etc) available in market. I have seen lot of improvements over last year itself when compared to previous versions. This is one such platform where everything looks good at first sight but there can always be room for improvement if needed. Nothing specific as its just working great all around. Just make sure you keep your team up-to date with latest developments which comes out every now & then. Integrating it seamlessly with other applications like ERP or CRM systems etc.
