THE PROBLEM

You're losing up to 15% of revenue to preventable payment failures

False declines, bad data, poor routing — most payment failures are completely preventable. Traditional gateways just process. Paystaq optimizes.

False Declines
~8%
Legitimate transactions wrongly declined by issuers due to poor data quality — each one a lost customer and lost revenue.
Poor Routing
~5%
Revenue left on the table from routing to sub-optimal acquirers without real-time performance data.
Rigid Risk Engines
~4%
Valid transactions blocked by rule-based fraud systems that can't distinguish real threats from legitimate customers.
HOW IT WORKS

Up and running in three steps

No rip-and-replace. No months of engineering work. Connect your existing stack and start optimizing immediately.

01
Connect

Integrate once via our single API or drop-in Cashier. Connect to 200+ payment providers, acquirers, and APMs without building individual integrations.

5 days average integration time
02
Optimize

Every transaction passes through UPQS data validation, Sentinel ML risk scoring, and Smart Routing — automatically, in real-time, with zero configuration required.

3 optimization layers, <400ms latency
03
Approve

Transactions reach the optimal acquirer with clean data and accurate risk scores — maximizing the probability of approval and minimizing false declines.

Up to 20% higher acceptance rate
THE SOLUTION

Three levels of optimization.
Compounded results.

Each level builds on the last, creating multiplicative improvements. No single-layer solution can match this.

Level 1
UPQS
+6–8% approval rate

Validates and enriches transaction data before submission. Eliminates preventable declines from formatting errors and missing fields that trigger issuer rejection before reaching the bank.

Data ValidationFormat EnrichmentIssuer Compliance
Level 2
Sentinel ML
+4–6% approval rate

AI-powered risk assessment that learns your transaction patterns in real-time. Blocks real fraud while approving legitimate customers that rule-based systems wrongly reject.

Machine LearningReal-time AnalysisFalse Positive Reduction
Level 3
Smart Routing
+3–6% approval rate

Routes each transaction to the optimal acquirer based on real-time performance, card type, geography, and historical success rates. Always takes the path most likely to succeed.
