I have to check my company's incoming and outgoing payments on a daily basis and was able to set up a custom template for what information I want to pull. This makes it easy for me to make this everyday task a quick one while I use other similar reporting sites that are not so easy to navigate. This streamlined process also makes it easy to explain to other people. We also can use card swipes to charge people onsite at events and their payments are very quickly reflected online.
Using cartpaysolutions.com I was able to go from an absolute noob to a full-fledged application very quickly. I was able to refactor my code using the PHP SDK and very quickly extended our application to include some more challenging aspects of ecommerce (refunds, user management etc.).
