I will develop a custom shopify app with billing and admin UI
Shop Dev Lab
About this gig
"You can always build a small private app for the features you feel are missing - the Admin API covers almost everything."
That is the standard advice on the Shopify forums. It is correct. It also assumes you have a spare week.
I am the person you hand that to.
What I build:
- Private apps and focused scripts for your own store: bulk edits Shopify blocks, supplier and ERP sync, internal tools
- Public apps for the App Store, including the submission itself
- Embedded admin screens with App Bridge and Polaris
- Subscription billing through the Shopify Billing API
- Scheduled jobs, digests, email and Telegram alerts
My competitor-monitoring app is live on the Shopify App Store with the Built for Shopify badge, the platform's highest quality standard. It went from first line of code to a submitted listing in five days: OAuth, embedded UI, Billing API, GDPR webhooks, background jobs.
Stack: PHP 8, Laravel, GraphQL Admin API, official Shopify libraries. Clean code you can hand to another developer.
Fixed scope, fixed price, written communication only. No calls.
Tell me what Shopify will not let you do and I will tell you honestly if it is feasible and what it costs.

FAQ
I just need one thing Shopify will not do in bulk. Is that too small a job?
No, that is the most common request. A focused script that reads your spreadsheet and writes the fields Shopify blocks is usually a Basic package.
Can you submit the app to the Shopify App Store for me?
Yes, in Premium. It covers listing content, screenshots, compliance webhooks and fixing whatever reviewers flag, until the app is approved.
Do you work with existing apps?
Yes. I can extend, fix or take over an existing Shopify app. Send me the repository and I will review it before quoting.
Who owns the code?
You do. Full source is delivered on completion.
Do we need a call?
No. I work entirely in writing. Everything stays documented and timezones stop mattering.
