Shopify App Development Cost in 2026: Custom vs Public Apps, Revenue Share and Real Build Ranges

In this article
- Realistic 2026 ranges: $5,000–$25,000 for a custom app for one store, $25,000–$80,000 for an integration-heavy custom app, $40,000–$150,000 for a public Shopify App Store app, $150,000–$300,000+ for complex, high-volume apps.
- Shopify keeps 0% of your first $1M in lifetime app revenue and 15% above it, plus a 2.9% processing fee on all app billing and a one-time $19 Partner registration.
- The cost jump from custom to public comes from multi-store OAuth, billing, privacy webhooks, onboarding, listing and the App Store review, not from the feature itself.
- Plan 15–25% of the build per year for upkeep: Shopify ships a new API version every quarter, and public apps also need support, hosting and review re-checks.

Shopify app development cost at a glance
This page is about building apps that extend Shopify: admin tools, sync jobs, checkout logic, storefront widgets. If you need the store itself, our Shopify website development cost guide covers themes, plans and store builds.
The first question decides most of the budget: is the app for your store, or for every store?
| Simple custom app | Integration custom app | Public App Store app | Complex public app | |
|---|---|---|---|---|
| Build cost, professional team | $5,000–$25,000 | $25,000–$80,000 | $40,000–$150,000 | $150,000–$300,000+ |
| Typical hours | 80–350 | 400–1,200 | 700–2,200 | 2,200–5,000+ |
| Timeline | 2–6 weeks | 2–5 months | 3–6 months incl. review | 6–12 months |
| Examples | Order tagging, bulk price editor, a discount Function, a custom report | Two-way inventory and order sync with an ERP or WMS, B2B pricing from a PIM | Product options, reviews, upsells, shipping rules sold to many merchants | Subscriptions, POS extensions, marketplace sync, analytics on millions of orders |
| Goes through App Store review | No | No | Yes | Yes, often aiming for Built for Shopify |
| Monthly run cost | $0–$50 hosting | $50–$400 hosting, queues, monitoring | $100–$1,000 plus support time | $1,000–$10,000+ infrastructure and support |
Ranges assume a team with a developer, QA and someone who owns scope. A freelancer can ship a small custom app for $2,000–$6,000. That works when the logic is simple and the developer stays around for API upgrades.
Custom app vs public app: why the same feature costs twice as much
Shopify has two ways to distribute an app. A custom app is installed on one store, or on stores in one Plus organization, through a custom distribution link. A public app can be installed by any merchant, either unlisted or through the Shopify App Store. The feature can be identical. The surrounding work is not.
One 2026 change matters for anyone budgeting a custom app: since January 1, 2026, merchants can no longer create new apps through the "Develop apps" screen in the store admin. New custom apps are created in Shopify's Dev Dashboard or with Shopify CLI, with versioned configuration for scopes, URLs and webhooks. Existing legacy apps keep working. In practice, this makes a "quick admin API token" setup a small development task rather than a five-minute click, and it's the right moment to put the app in version control.
What a public app adds, and why each piece is mandatory:
- Multi-store installation. OAuth with token exchange, per-shop sessions, scopes requested only when needed, and clean behavior on uninstall and reinstall.
- Billing. Apps sold through the App Store must charge through Shopify (the Billing API or Shopify's managed pricing). Free trials, plan changes, usage charges and proration all need code and testing.
- Privacy webhooks. Every public app must handle Shopify's mandatory compliance webhooks for customer data requests, customer redaction and shop redaction. If you store customer data, deletion has to actually work.
- Onboarding and settings. The merchant installs the app without you on a call. The first screen has to explain itself.
- Listing and review. Screenshots, a demo video or screencast, a test account, and fixes after the reviewer's first round.
What Shopify takes from app sales in 2026
Shopify's revenue share terms changed on January 1, 2025, and they still apply in 2026. According to Shopify's developer documentation:
- $19 once to register a Partner account for the revenue share plan.
- 0% revenue share on the first $1M in lifetime gross app revenue, counted across all your apps and associated developer accounts. This replaced the older rule, which reset the $1M threshold every year.
- 15% on revenue above $1M, for developers earning under $20M a year.
- 15% on everything for developers above $20M in annual app revenue or companies with more than $100M in total revenue.
- 2.9% processing fee on all app billing, charged separately and regardless of the threshold, plus applicable sales tax.
Compared with mobile stores, that's generous early on. Apple takes 15% from day one under its Small Business Program, and Google Play's US terms since June 30, 2026 start at 10% on the first $1M. On Shopify, a new app pays only the 2.9% processing fee until it crosses $1M in lifetime sales.
The math that matters more for most new apps is the other side: how long it takes to earn back the build. A $60,000 app at an average of $25 a month per merchant needs 200 paying stores for a year just to recover the build, before support, hosting and marketing. Many App Store apps never reach that. If your business case depends on App Store sales, budget for marketing and support as seriously as for development, and see our SaaS development cost guide for the product side of that math.
The technical cost drivers specific to Shopify
40–300 hours depending on screens. Most apps live inside the Shopify admin as an embedded app, loaded in an iframe and wired up with App Bridge for navigation, toasts, modals and session tokens. Since October 2025, Shopify's unified Polaris web components are stable across admin, checkout, customer accounts and POS, and they load from Shopify's CDN with App Bridge. That's good for budgets: design work shrinks because the app should look like Shopify, and Built for Shopify reviewers check that it does. Custom-designed admin UIs cost more and score worse.
20–80 hours per extension. Theme app extensions put blocks on the storefront without editing theme code. Checkout UI extensions add fields and content to checkout (the deeper customization on information, shipping and payment steps needs Shopify Plus). Shopify Functions replace server calls with logic that runs inside Shopify for discounts, shipping, payment customization and validation. Admin actions, blocks and POS UI extensions add more surfaces. Each one is a separate target to build, test and keep current.
0–150 hours, depending on data volume. The GraphQL Admin API limits apps by calculated query cost: 100 points per second on standard plans, 200 on Advanced, 1,000 on Shopify Plus and 2,000 on Commerce Components, with a 1,000-point cap on a single query. Since April 1, 2025, new public apps submitted to the App Store must use GraphQL only; the REST Admin API has been legacy since October 2024. A small app never notices. An app that syncs 100,000 products or years of orders needs bulk operations, webhooks, job queues, backoff and idempotent writes.
A recurring cost, not a one-time one. Shopify releases a new API version every quarter and supports each for at least 12 months. Every app has to move forward at least once a year, and some releases change fields or deprecate whole flows (product APIs, checkout.liquid, legacy custom apps). For a small app, an upgrade takes a day or two. For a large public app with many extensions, it can be a sprint.

Pick the distribution model, the surfaces the app touches and how much data it moves. The model uses planning hours from real estimates, adds 30% for QA and project management, and applies the rate you choose. It also estimates the monthly run cost and yearly upkeep.
Estimate your Shopify app build
Typical 2026 vendor rates for mid-to-senior developers with Shopify app experience. Upkeep is 15% of the build per year for custom apps and 23% for public apps, which also need merchant support. Hosting assumes a standard cloud setup; Shopify does not host app backends. Marketing, the App Store listing's ongoing optimization and the 2.9% processing fee are not included.
Two patterns show up when you try it. Moving the same app from "custom, one store" to "App Store" adds 250–400 hours before any feature changes. And on custom apps, integrations dominate: one ERP sync often costs more than the entire admin UI.
Where the money goes in a public app
Rates by region, compared fairly
Same public app, the one from the chart above (about 1,100 hours with QA): midpoint build cost by team location.
- US onshore: full overlap with your team and easy live product sessions. Highest cost per hour.
- Latin America: what US buyers call nearshore, with most of the working day shared. Rates close to Central Europe. Our nearshore rates guide has per-country numbers.
- Central & Eastern Europe (Gilzor works from Poland and Cyprus): offshore for the US, with about 2–4 shared hours with the East Coast on a shifted schedule and little with the West Coast. App work fits that well: specs, staging stores and recorded demos carry most of the communication.
- South and Southeast Asia: lowest rates, widest spread in quality. Budget more of your own time for review, especially before the App Store submission.

Should you build an app at all?
Six questions. The result tells you whether to build a custom app, a public app, or skip development and configure what exists.
Which Shopify app route fits you?
App Store submission readiness
The review is where public app timelines slip. Shopify has published a target of roughly 8–10 business days for a first review, and developers in Shopify's community commonly report 7–14 business days, longer when fixes are needed. Most first submissions come back at least once. Tick what's already true for your app.
Public app review checklist
Hidden costs: what you pay after launch
| Cost | Typical 2026 range | Notes |
|---|---|---|
| API version upgrades | 1–10 developer days a year | Quarterly Shopify releases, each supported for at least 12 months. Skipping them breaks the app when an old version is retired. |
| Maintenance and changes | 15–20% of build per year (custom), 20–25% (public) | Bug fixes, new Shopify features merchants ask for, dependency updates, security patches. |
| Hosting and infrastructure | $20–$1,000+/month | Shopify doesn't host app backends. Servers, database, queues, logging and monitoring scale with installs and data. |
| Merchant support | A few hours a week to a full-time role | Public apps only. Fast, helpful replies drive App Store reviews, and reviews drive installs. |
| Shopify fees on app revenue | 2.9% processing; 15% share above $1M lifetime | Plus sales tax handling. The $19 registration is the only fixed fee. |
| App Store marketing | $500–$10,000+/month | Listing optimization, Shopify App Store ads, content, partnerships. New listings without it often stall at a handful of installs. |
| Compliance and security | Usually small, larger with customer data | Privacy webhooks, data retention rules, and protected customer data requirements if you read customer names, emails or addresses. Apps touching payments data face PCI DSS scope. |
| Re-review and Built for Shopify | 20–80 hours when triggered | Major changes and annual Built for Shopify re-checks can mean performance or design work. |
What we see in estimates and first calls
- "It's a simple app" usually means a simple screen on top of a hard sync. The admin page takes a week. Deciding which system owns stock, price and order status, and what happens when the ERP is down, takes longer. We ask that per field before we estimate. Our API integration cost guide covers the general math.
- Public apps get scoped like custom apps. Founders budget the feature and forget billing, onboarding, privacy webhooks, listing assets and support tooling. That's where a $30,000 plan becomes a $55,000 invoice.
- Rate limits show up in production, not in demos. A development store with 50 products never throttles. A merchant with 80,000 variants on a standard plan does, on day one. We test with realistic data volumes before launch.
- Inherited apps are often stuck on old API versions. When we pick up an app from another team, the first job is frequently a forced upgrade with a deadline. Our tech troubleshooting work often starts there.
- Overruns come from unwritten scope. The Standish Group's CHAOS 2020 report classed only about 31% of software projects as successful on time, budget and scope. Shopify apps are small projects, but the cause is the same: edge cases that nobody wrote down until the reviewer or the first big merchant found them.
How to reduce the cost without breaking the app
- Check Shopify Flow and existing apps firstMany "we need an app" requests are a Flow automation plus one existing app. Build only the part nothing covers.
- Start as a custom or unlisted appShip to your own store or three pilot merchants. Add billing, listing and review when the feature is proven.
- Use Functions and extensions instead of serversDiscount, shipping and validation logic that runs inside Shopify needs no hosting, scales with Shopify and avoids most rate-limit work.
- Stay inside PolarisShopify's components cover settings, lists, forms and most dashboards. Custom design inside the admin costs more and reviews worse.
- Write the data spec before quotesRecords, volumes, sync direction and the owner of each field. Vendors stop padding for uncertainty. For larger apps, a short business analysis phase does this properly.
- Pick the team region for how you workIf your team works from tickets and async demos, an offshore team saves 50–75% against US rates. If you need daily live sessions, the overlap is worth paying for.
Testing with realistic data volume. Logging and alerts on every sync job. Proper uninstall and data deletion. A named owner for the yearly API upgrade. Each costs little up front; skipping them costs merchants, reviews or a broken checkout. Structured QA across plans, themes and store sizes is what gets a public app through review on the first or second round.

Where Gilzor fits
We build custom Shopify apps, integrations and extensions as part of our web development work, with QA on the same team. Only 5% of the tasks we send to QA come back to developers; that's our own metric. For US clients, we work from Poland and Cyprus with a few shared hours on East Coast time and written, async-first reporting. If your app is one piece of a bigger product, our web application development cost guide covers the rest.
Send us the workflow, the data volumes and any quote you already have. We'll tell you whether it should be an app at all, and which kind.
