Tapbuy

- Address auto-complete and guest-checkout form pre-filling.
- Dynamic coupon code validation and subtotal recalculation display.
- Basic Stripe / PayPal / Apple Pay component integration.
- Cart drawer and floating fast-checkout CTA widgets.

- Out-of-the-box maintenance of enterprise Magento 2 GraphQL and REST API version compatibility.
- Built-in performance tuning for mobile web views inside Instagram and TikTok in-app browsers.
- Vendor accountability and SLA guarantees for uptime during high-volume sale events (e.g., Black Friday).
- Turnkey support for complex enterprise tax platforms (Vertex/Avalara) and localized payment methods.
