The ability to integrate with our accounting system is key in getting us up & running quickly when we needed it most! We have not had any issues so far - they support are very responsive which makes them easy partners of choice from day one :) Definitely consider this integration if you need an ERP solution that has quick implementation times (we were able to get fully functional within just over 2 weeks!). There's no downside really here other than perhaps needing more people at your end who understand how to use their API properly but even then there should be little work involved after going through some tutorials/documentation provided online or via email etc..
