People-friendly. Inner Fence was an early arrival on the mobile payment scene, debuting Credit Card Terminal in 2008. The app hits all the basics of credit card payment processing, plus it integrates seamlessly with app partners to form a full invoicing and payment solution. Build on time tracking, product catalog, point of sale and some CRM features. Inner Fence makes customer support a top priority.
Pro: Plays nice with customers and other apps.
Con: No-frills design leaves out time-saving "cash register" features, such as preset items and automatic sales tax calculation.
