SumUp POS

SumUp POS (formerly Goodtill) is a fiercely aggressive, highly tactical European leviathan that mathematically rules the "Micro-Merchant and Pop-Up" market across Europe. Known for its ultra-cheap, highly portable card readers, it engineered a surprisingly powerful POS backend to support them. It is the absolute weapon of choice for massive European pop-up retail events and small boutiques who demand mathematically flawless, hyper-mobile payment processing.
