Your checkout.
Optimised end-to-end.
Cashier is a fully hosted, white-label checkout that connects to your MIDs, routes transactions intelligently, and applies Paystaq's three-level approval stack on every payment.
Everything your checkout needs. Nothing it doesn't.
Cashier handles the full payment stack — from the UI your customers see to the routing decisions that determine whether a transaction succeeds.
From click to confirmation in five steps
Every transaction passes through all three optimisation layers before reaching the acquirer — automatically, every time.
Cashier is optimised for the hardest payment environments
The same three-level stack, tuned for the specific decline patterns and compliance requirements of each vertical.
iGaming merchants face the highest decline rates in any vertical — partly due to MCC classification, partly due to blunt fraud rules that can't distinguish a genuine player from a bad actor. Cashier's UPQS validation and Sentinel ML are tuned for high-frequency, high-risk transaction profiles, keeping approval rates up without opening the door to chargebacks.
E-commerce businesses lose revenue at checkout in ways that rarely show up clearly in dashboards — card validation failures, acquirer-specific formatting mismatches, and routing to underperforming providers during peak traffic. Cashier handles all of this automatically, so merchants see higher approval rates without changing anything about their checkout flow.
