Shopify App Store · 12 apps · development to order

12 apps in the App Store. The next one is yours.

Since 2023 we have released twelve apps for Shopify: shipping, marketplaces, fiscal receipts, invoices, prices, cash on delivery and visibility in AI assistants. All passed review and remain in the catalogue. Below is what they do and what they cost.

What we build to order

Master Development is a Shopify Select Partner. Shopify gives this tier to partners who bring new merchants to the platform and support their early success.

Stack: Remix / React Router 7, Polaris, Prisma with MySQL or Postgres, AWS SQS and Lambda for background jobs. Ruby on Rails for selected projects; Agentic Fuel is written in it.

How we work

  1. A 45-minute conversation

    Free. You describe the task; we say whether it will pass review and what it will require from the store.

  2. Functional specification

    Screens, data model, webhooks, pricing plans and the review checklist. The specification has a fixed price, and it fixes the development price too.

  3. Development

    A weekly demo on a development store with your data. You test every increment yourself.

  4. Listing and review

    Submission, replies to reviewers, resubmission, until the app is live. Then monthly support: API versions, deprecations, the listing.

Questions from the first call

Will you build a payment app for a market without Shopify Payments?

Yes. Master Development builds payment apps for Shopify and QR and bank-transfer flows under Shopify's rules for payment apps.

Do you handle the App Store review yourselves?

Yes. Submission, replies to reviewer comments and resubmission are included in the fixed price. Twelve of our apps passed Shopify's review and remain in the catalogue.

Who owns the app's code?

The client. The repository and the Partner account are yours; we work inside them.

How much does Shopify app development cost?

At Master Development the price of a Shopify app is fixed after the functional specification. The specification itself also costs a fixed sum, and the first 45-minute conversation is free.

Describe the app in three sentences.

We will say whether it will pass review and how big the job is. If one of the twelve already covers the task, we will say that too.
