How much does a custom Shopify app cost in 2026, and how to hire the right Shopify developer

Shopify app development cost is one of the first things a merchant asks about, and one of the hardest to get a straight answer to. Quotes for what sounds like the same app can be far apart, because "a Shopify app" can mean a single admin screen for your own store or a public product that installs on thousands of stores and has to pass Shopify's review.

This guide is for store owners and founders who need a custom app, or want to sell one, and have to hire someone to build it. It covers what drives the cost, my own published starting prices, the running costs after launch, and the questions that separate a good Shopify developer from a risky one. For the technical side of building an app, I wrote up the lessons from building FrameRx separately.

Custom app or public app: the first cost decision

A custom app is built for one store, or one organisation's stores, and installed directly. Since 1 January 2026, new ones are created in the Dev Dashboard rather than the Shopify admin. It never goes through App Store review, and it only has to work with your theme, your data and your processes.

A public app is a product. It has to install cleanly on stores you will never see, handle uninstalls and data requests, charge merchants through Shopify and meet the App Store requirements. Among them: new public apps must use only the GraphQL Admin API (since 1 April 2025), theme changes must go through theme app extensions, and app charges must go through Shopify's billing. The review team can reject an app, so time for fixes after review belongs in the plan.

The same feature costs more as a public app, and most of the extra work is invisible: settings for merchants who sell differently, edge cases across themes, onboarding, billing and support.

What drives Shopify app development cost

After the custom-or-public decision, these move the price most:

• Where the app shows up. An admin-only tool is the cheapest. A storefront feature adds a theme app extension that has to work across themes and on phones. Checkout is a different category again.
• Checkout logic and Shopify Plus. Discounts, delivery options, payment methods and cart validation run on Shopify Functions. A custom app that uses Functions only works on Plus; on other plans the same logic has to ship as a public app. Knowing this up front stops you paying for the wrong architecture.
• Data kept in sync. Reading products once is simple. Keeping orders, products or stock in sync means webhooks, which can arrive twice or out of order, a reconciliation job to catch what was missed, and API rate limits that differ by plan.
• Settings or hard-coded rules. Rules you change yourself cost more up front and less every time your business changes. FrameRx's no-code rule builder is the far end of that scale.
• Customer data. Apps that read names, addresses, emails or phone numbers handle what Shopify calls protected customer data, which brings extra requirements, and custom apps at that level need the Grow plan or above.
• Billing. In its Spring '26 Edition (17 June 2026), Shopify announced that Shopify App Pricing replaces both Managed Pricing and the legacy Billing API. Plans, trials and usage charges still have to be set up and tested.
• Other systems. An ERP, a 3PL, Amazon or TikTok Shop each add their own API, authentication and failure modes.

My published Shopify app plans

These are my starting prices for Shopify apps, as listed on the pricing page:

Plan	Starts at	What it covers
MVP	$2,000	A custom app for your store with one focused feature, a storefront block or an admin tool, with settings you change without code
Flexible	$4,500	A storefront flow plus admin screens, with order and product data kept in sync and working across your theme
Advanced	$8,000	A public app built for many stores: Shopify billing with plans and trials, rule builders and complex logic, help with the App Store listing and review

FrameRx is the Advanced kind: a public app that lets any eyewear store sell prescription lenses, with a guided lens flow on the storefront, a verification queue for the merchant and a no-code rule builder behind both. Two earlier eyewear apps of mine are public on GitHub.

Every plan comes with a fixed quote after a short brief, before any work starts; payment in milestones, each one something you can open and try; and the code and accounts in your name, with handover notes. The figures above are starting points, and the drivers in the previous section decide where your quote lands.

The running costs after launch

Shopify app development cost does not stop at launch. Plan for these:

• Hosting. Most apps have a backend and a database, which means a monthly hosting bill in your name. Shopify's new static apps let simple admin apps run without a server of your own, which removes that cost for some tools.
• API versions. Shopify releases a new API version every quarter and supports each for at least 12 months (versioning docs). When a version drops out of support, Shopify answers with the oldest supported version instead, which can change behaviour without an error. Budget for an update at least once a year.
• Platform changes. 2026 brought two big ones: legacy custom apps closed to new builds, and Shopify Scripts stopped running on 30 June 2026, with editing closed from 15 April. Apps and stores that relied on either needed work.
• Revenue share, for public apps. Shopify takes 0% of the first $1 million of lifetime app revenue and 15% above it, counting revenue from 1 January 2025, plus a one-time $19 Partner registration fee.
• Support. A public app has merchants who email you, and somebody has to answer.

How to hire a Shopify developer: questions to ask

My general guide to hiring a freelance developer covers scope, communication and ownership. These questions are specific to Shopify:

1. "Custom app or public app, and why?" The answer should match whether you will ever sell it to other stores.
2. "Whose organisation will the app live in?" It should be yours. The developer then needs a staff account with the app development permission, because collaborator accounts cannot reach the Dev Dashboard.
3. "Does any of this need Shopify Functions, and are we on the right plan?" A good Shopify Functions developer raises the Plus question before you do.
4. "How will the storefront part be added?" Through theme app extensions, not by pasting code into your theme.
5. "How do you handle missed or duplicate webhooks?" Listen for deduplication and a reconciliation job.
6. "What happens when the API version changes?" You want a plan, not a shrug.
7. "Can I see a Shopify app you shipped?" Something live, installable or public beats screenshots.

Red flags in a Shopify developer's quote

• They ask for your owner login or a full-access staff account instead of building an app with only the permissions it needs.
• They plan to edit your theme files for something an app block should do.
• They suggest creating a "private app" in your admin, which is no longer possible for new apps.
• A new public app is planned on the REST Admin API, which Shopify has treated as legacy since October 2024.
• Checkout changes are promised on a non-Plus store with no mention of Functions or plan limits.
• The app will live in their account, and the handover is vague.

Shopify developer hourly rate or fixed quote?

Hourly rates for Shopify developers vary widely, and a rate on its own tells you little about the total Shopify app development cost. A low rate on a vague scope often ends up costing more than a higher one on a clear scope. What matters is the total for a written list of what is included, and what is not.

I do not quote by the hour. Every project gets a fixed quote after a short brief, and each milestone is something you can try. When you compare quotes, compare scope line by line: sync, merchant settings, review help, hosting setup and handover. If you are hiring across borders for the first time, my page on working with a remote developer explains how the process runs.

FAQ

How much does a custom Shopify app cost?

It depends on what the app touches. On my published plans, a custom app with one focused feature for your store starts at $2,000, a storefront flow with admin screens and synced order or product data starts at $4,500, and a public app built for many stores starts at $8,000. Every project gets a fixed quote after a short brief, and running costs such as hosting and yearly API updates come on top.

Can a custom Shopify app change my checkout?

Partly, and your plan decides how much. Checkout logic such as discounts, delivery options, payment methods and validation runs on Shopify Functions, and a custom app containing Functions only runs on Shopify Plus. On Basic, Grow or Advanced, that logic has to come from a public app, which costs more to build. Adding interface elements to the information, shipping and payment steps of checkout is also limited to Plus.

What are the ongoing costs of a Shopify app?

Mainly hosting and updates, plus support and revenue share for public apps. Most apps need a server and database billed monthly, though Shopify's static apps can run simple admin tools without one. Shopify releases a new API version each quarter and supports each one for at least 12 months, so plan an update at least yearly. Public apps also pay Shopify 15% of revenue above their first $1 million of lifetime earnings.

To get a fixed quote, send me a short brief: the problem in your store today, who uses each side of the app, your Shopify plan, the data involved and whether the app is for your store only or for other merchants too. You can start from the Shopify app Flexible plan, see my Shopify app development service, or check first whether Shopify Flow can do the job without an app.
