frequently_asked()
01What types of Shopify apps do you build?
Public apps for the App Store, private apps for single merchants, custom B2B portals, reporting dashboards, checkout UI extensions, Shopify Functions for custom logic, and headless commerce front ends.
02Do you handle Shopify App Store submission?
Yes. App Store review is strict (security, GDPR, billing, merchant flows, performance). We build to those standards from the start and handle the submission end to end, including revisions.
03What's your tech stack for Shopify apps?
Remix + Polaris + Shopify CLI + TypeScript, deployed on Vercel or Fly.io. Shopify's recommended modern stack. For performance-critical apps we use Shopify Functions (Rust/JS) rather than legacy scripts.
04Do you handle billing, webhooks, and GDPR?
Yes. Billing API, webhook handlers for all Shopify events, and the three mandatory GDPR webhooks (customer data request, customer redaction, shop redaction) are baseline on every app we ship.
05Can you build private apps for a single store?
Yes. Custom apps (Shopify's replacement for private apps) are common when off-the-shelf apps don't fit your workflow. Faster to build than public apps since there's no App Store review.
06What's included with a custom app build?
Production code, automated tests, CI pipeline, GDPR and billing flows, Polaris-consistent admin UI, documentation, and a post-launch warranty period. Full source and hosting ownership is yours.
