How key sectors in Bulgaria use payment gateway & PSP integration
Payment Gateway & PSP Integration for IT outsourcing
IT outsourcing businesses in Bulgaria usually need fast release cycles, scalable multi-tenant architecture and extra senior engineering capacity. For them, our payment gateway & PSP integration typically starts with subscriptions & invoicing (recurring billing, dunning and proration) and adds reconciliation as the platform grows. Progress is tracked on release frequency and customer churn.
Payment Gateway & PSP Integration for Fintech
Fintech businesses in Bulgaria usually need secure onboarding, ledgers that reconcile to the cent, real-time payments and audit-ready reporting. For them, our payment gateway & PSP integration typically starts with 3ds2 & fraud rules (strong customer authentication with risk-based exemptions) and adds multi-psp orchestration as the platform grows. Progress is tracked on onboarding completion rate and time to approve an application.
Payment Gateway & PSP Integration for E-commerce
E-commerce businesses in Bulgaria usually need fast storefronts, omnichannel inventory, loyalty and frictionless checkout.

Progress is tracked on checkout conversion and stock accuracy.
