At WTSS, we are passionate about helping banks provide their customers with the best payment services and experiences possible. We offer the most convenient production diagnostic services, allowing our clients to carry out real-payment transactions and verify the integrity of their services.

We are committed to giving our clients the insights they need to identify risks and make informed decisions about their payment services. Utilising our international retail, business, and corporate accounts infrastructure, we create custom, end-to-end payment service verifications and accumulate data from transactions. We then use this data and our proprietary insights to provide the answers you need.

At WTSS, we are excited to be a part of the journey to make payment services more reliable, secure and efficient. We are proud to be an innovator in providing the best payment services possible, and look forward to continuing to provide our clients with the best diagnostic services available.

We execute real payment transactions and receive reporting for all payment types across the globe. We have accounts in nearly all EU countries, USA, TR, HK and SG. If we need to cover a specific country that we are not active in yet, we will simply extend our network.

All payment types and related products supported

We can handle any transaction or reporting type. Book-to-book, book-to-bank, cross-bank, credit transfers, direct debits, bulk, real-time, FX, TPP (PSD2) or any other kind you would like to have verified.

Automated tests in Web, App, API and File-based channels

We have four base verification setups: File Transfer, API, Online and Mobile app. You can verify your journeys using one channel or across channels. We automate verifications as much as possible but also support you with specific requests like incident replication or customer mimics.
