Global merchants
For merchants selling across borders, checkout is where growth quietly leaks: the wrong local method, the wrong currency, a decline that should have been an approval. BLK Tech routes around all three, with cross-border processing and fraud defence in the same flow.
Smart routing and retry cascades recover declines that a single acquirer would have written off.
The payment methods and currency customers in each market actually expect to see.
AI-driven screening and chargeback defence that protect margin without blocking good customers.
Services presented
The services we present to global merchants and e-commerce groups, aimed at the two numbers that matter: acceptance rate and total cost of payments.
Multi-currency transaction processing with compliance built into international flows.
Cards, bank rails and local methods selected per market so checkout matches local habit.
Price, collect and settle in the currencies that suit your treasury, with FX recorded per transaction.
Dynamic risk assessment, device and velocity signals, and step-up authentication where it earns its friction.
Evidence capture at authorisation and a dispute workflow that does not rely on screenshots.

Selling internationally means meeting several regimes at once. Authentication is applied where the issuer or regulator requires it, screening runs inside the authorisation flow, and card data is tokenised in a PCI-scoped vault, so growing into a new market does not quietly expand your compliance exposure.
Security & complianceFAQ
Only where the change helps conversion: the methods and currency shown per market. The request pattern your developers integrate stays the same as you add markets.
Yes. Merchants commonly start with one region or one method, compare acceptance against their existing route, then expand.
Refunds run through the same API; disputes use the evidence captured at authorisation, with a workflow that keeps documentation and deadlines in one place.
