Eliminated warranty-pickup support emails
Years on Checkout Ninja, dozens of custom blocks shipped to spec.
India's premium audio retailer, on Plus since 2020. The first merchant on the custom contract work that became Checkout Ninja. Custom-built blocks for warranty pickup, audio-test scheduling, gift wrapping, and bulk B2B orders — all without theme code.
What wasn't working.
Native checkout couldn't capture warranty intent
Headphone Zone sells premium headphones — Sennheisers, Audeze, Focals — where customers often want to book a warranty pickup appointment alongside the purchase. Native Shopify has no field for 'preferred warranty pickup time.' Without it, customers had to email after purchase, which created 100+ support tickets per month.
What we shipped.
Custom field block tied to fulfillment
We built a custom Text Input field block with date-picker integration. Captured at checkout, the answer pipes into the fulfillment system. Over the next five years, we extended the same approach to: audio-test scheduling, gift wrapping for premium models, bulk B2B PO fields, regional language toggles, payment-method restrictions for trade accounts.
What changed.
Continuous deployment, zero downtime
Custom-built and now part of the library
Custom blocks reusable across other Plus merchants
Fantastic app, highly recommended. We've been using it for years without a hic. Sabeeh is a great partner and has built a long list of checkout customisations suited to our store. A must have for all your Shopify checkout needs!
