Frequently Asked Questions

Everything you need
to know before hiring.

OpenCart 3 or 4 — which?

Yes. Custom modules, OCmod modifications, custom payment + shipping methods, custom order total modules, admin event listeners. Marketplace-ready extensions on request.
What about India-specific payments (UPI, Razorpay, Paytm)?
Yes. We have specialists in Indian payment gateways — Razorpay (UPI + cards + netbanking), Paytm, PayU, Cashfree, CCAvenue. Plus international: Stripe, PayPal, Klarna.
What does the 14-day SLA actually mean?
From discovery (day 1) to an OpenCart developer onboarded and shipping their first extension / theme PR by day 14.
How does the replacement guarantee work?
5 business days notice, 2-3 replacement profiles within 48 hours.
What about performance tuning?
MySQL tuning, Redis caching, Varnish FPC, image optimization (WebP + responsive srcset), Nginx + PHP-FPM tuning. Typical wins: TTFB 1.2s → 280ms, Lighthouse +40 points.
