Shopify app development that survives App Store review
Public apps, private apps, and the embedded admin tooling merchants live in all day. Built against the quarterly API cycle so a version bump is a scheduled task rather than an outage.
What we build
Public App Store listings
Listings built to pass review the first time: OAuth, mandatory webhooks, GDPR endpoints, and the billing API wired the way Shopify expects.
Quarterly API version upgrades
Shopify deprecates on a schedule. We build against versioned endpoints so an upgrade is a planned change, not a Monday morning incident.
Webhooks and event reliability
Idempotent handlers, retries, and reconciliation, because a missed order webhook is a missing order in whatever you built downstream.
Embedded admin tooling
Polaris-native screens inside the Shopify admin, so staff never learn a second interface to do their job.
Scanning and fast order entry
Barcode and SKU-first workflows for merchants who work off a rail, not off a customer record. Draft Deputy is this pattern in production.
Server-side conversion tracking
Conversions API events sent from the server and deduplicated against the browser, so ad blockers stop distorting attribution.
Engineered for production, not presentation
Reference architecture
- Storefront / admin
- App layer (OAuth, billing)
- Webhook + job queue
- Your data store
- Downstream systems
The queue between webhook and data store is the part most Shopify apps skip, and the reason they lose orders under burst traffic.

How Shopify app builds are usually scoped
Project Build

The team that builds it, ships it
From discovery to production, the same senior engineers own every line. No handoff between sales and delivery: the people in the room are the people who write the code.
Frequently asked questions
Yes, and the work that decides it happens before submission: OAuth done properly, the mandatory GDPR webhooks implemented, billing through the Shopify billing API, and a listing that matches what the app actually does. Most rejections we see are for one of those four.
