Your Quality Confirmed

Mission Statement

Banks and payment providers are under constant public scrutiny. Whether it’s about paying or getting paid, there’s no room for compromise: the risk of bad publicity, reputational damage, loss of market share, customer churn and other adverse effects affecting the top line is far too great. Moreover, there’s new market entrants, strict rulebooks, scheme updates and innovations to take into account.

This is where testing comes into play. Testing is key in helping companies confirm quality, ensuring that their payment solutions adhere to governing specifications and creating a solid brand image. Because the payments world has its own characteristics, strict requirements, regulatory mandates, fast technology evolution, far-stretched security rules, mandatory certifications, tight deadlines, … It needs specialized test software, simulator tools and services designed for the fintech world.
