You may have noticed that we use the shopping cart provider GetDPD.com. I super-duper love GetDPD as our cart provider. They are responsive to questions and have everything we need to effectively sell software online. Seriously, if you're not using them, go check them out.
If you are using GetDPD, then you will likely enjoy one of our favorite apps on the App Store: DPD Check. DPD Check uses GetDPD.com's read-only API to provide a view of your sales on iPhone, iPad, or iPod Touch. The main view is your sales for the day at a glance, and then there are 30-day graphs and trend information.
We love DPD Check. It's so handy to get a quick check-in on our stats from our iPhones to make sure everything looks normal.
