Prevent checkout failure, cart abandonment glitches, and catalog desynchronization during high-stakes sales events. Zero-Defect pairs Canadian Quality Architects with nearshore squads to stress-test headless storefronts, omnichannel POS networks, and high-volume payment gateways.
Engineered to satisfy high-revenue marketing launches, instant checkout conversions, and omnichannel inventory accuracy.
Distributed load injection simulating tens of thousands of simultaneous shoppers entering flash sales, verifying payment queue workers, cart hold timers, and auto-scaling cloud clusters.
Automated integration regression between physical in-store POS registers, native mobile apps, and headless e-commerce microservices to prevent inventory drift and split-order errors.
Experienced Brazilian SDET squads operating directly in North American time zones, running automated regression across Shopify Plus, Salesforce Commerce Cloud, commercetools, and custom headless stacks.
How Zero-Defect squads safeguard high-volume digital storefronts and omnichannel retail systems.
