GATEWAY QUALITY INDEX (GQI)

Evaluation of payment method quality before integration — available by request.

UNDERSTAND THE QUALITY OF A PAYMENT METHOD BEFORE INTEGRATING IT.#

From €0/month.
PayStar analyzes real approval rates for each PSP and payment method, tracks traffic volume and data confidence, updates commercial terms, checks legal requirements, and helps payment teams validate methods quickly before scaling or launching new GEOs.
Access is granted only to verified companies, after a short introduction.

MANAGING PAYMENT METHODS HAS BECOME IMPOSSIBLE WITHOUT UP-TO-DATE INTELLIGENCE.#

Every month, PSPs:
add new methods
deprecate old ones
change API
update commissions, settlement rules, limits
degrade on specific GEOs without warning
And payment teams:
❌ discover real success rates only after integration
❌ waste weeks testing methods that will never work
❌ rely on outdated or incomplete provider information
❌ operate blindly when entering new markets

Traffic confidence (Low / Medium / High)
