I really love FreeAgent and the fact the integration with Shopify is free can save a lot of money for a new business like us at rudeoffensive.com. There were a fair few teething problems to start with but FreeAgent's support has been amazing. Now all the original issues I had have been resolved I'd definitely recommend to anyone to give FreeAgent a try
