Cost to build an app like Shopify
A Shopify-like app is B2B SaaS, not e-commerce. Your customer is the merchant, and what you are selling is the ability to run a store. That means multi-tenancy, per-tenant configuration and billing, an app ecosystem, and a mobile app that is an administration console rather than a shopfront.
What you are actually building
An app like Shopify is three or four screens people recognise sitting on a great deal of engineering they never see. These are the screens that define the shape — and the part of each one that costs real money.
Catalogue and search
Variants, inventory, facets and typo tolerance. Search relevance is the whole difference between a catalogue and a shop.
Checkout
Addresses, tax, shipping rates, promotions, wallets and 3-D Secure. The most tested screen in the app and the most regulated.
After the order
Orders, tracking, returns and refunds — easy to leave out of a demo, and the first thing support asks for in week one.

What makes a Shopify-like app expensive
Three things dominate this shape of product. Everything else is comparatively ordinary app development.
Multi-tenancy
Isolating every merchant's data, configuration, domain and billing, with per-tenant limits that cannot leak across the boundary.
Extensibility
Themes, apps and webhooks turn the platform into an ecosystem. It also means public APIs, versioning and developer documentation.
Merchant billing
Plans, usage-based charges, trials and per-transaction fees, all correct enough that merchants trust the invoice.

How long, and who builds it
The $717,000–$1,172,000 figure assumes this schedule and this team. Both scale with the answers in the calculator above — and neither is a quote.
Delivery timeline — 9–13 months
- Discovery & product definition4–6 wks
- UI/UX design6–9 wks
- Development (app + backend)20–29 wks
- Integrations & infrastructure5–8 wks
- QA & security testing5–8 wks
- Store submission & launch2–3 wks
The team — 7 people
- Product manager1×
- UI/UX designer1×
- Mobile developer1×
- Backend developer2×
- QA engineer1×
- Security engineer1×
The phases add to more than the total on purpose: design starts before discovery finishes and QA runs alongside development rather than after it. 7 people is about 7.0 full-time equivalents — a smaller team takes proportionally longer, and a much larger one does not go proportionally faster. The two roles most often missing from a first plan are DevOps and QA, which together are 15% of this build.
Technology considerations
A stack that would serve this product shape well. A recommendation for what you could build — not a claim about what Shopify runs.
| Layer | Suggestion |
|---|---|
| Mobile | A shared cross-platform codebase for mobile plus a web client, since most work happens on a desktop |
| Backend | Node.js or Go services with a document/collaboration service split out |
| Database | PostgreSQL, with document state stored as an append-only operation log |
| Cache | Redis for presence and session state |
| Search | OpenSearch across documents, with per-tenant index isolation |
| Real-time | WebSocket with CRDT or OT for concurrent editing |
| Cloud | AWS |
| Object storage | S3 for attachments and file uploads |
| Monitoring | Datadog with sync-conflict and API-latency dashboards |
Top cost drivers
- 1
Enterprise backend architecture17% of the build
Justified by a contractual uptime commitment, a regulated workload, or a user base large enough that an hour of downtime is a material financial event.
- 2
6 third-party integrations5% of the build
Every external service is code you write, failure modes you handle and an API that will change without asking you. The ones you can defer are the cheapest scope cuts available.
- 3
SOC 2 Type II compliance work4% of the build
Engineering and evidence work to make an audit survivable. Certification fees, legal review and auditor time are separate costs that this estimate excludes.
- 4
Cross-platform + web app3% of the build
Two separate native codebases means the client is built twice. Moving to React Native or Flutter would cut roughly a third of your mobile hours, at the cost of native modules wherever you touch device hardware.
Infrastructure and maintenance
Neither of these is part of the build figure, and neither of them stops.
Cloud infrastructure
$651 – $7K/month
- Baseline environment$120–$420
- Application compute$54–$192
- Database$7–$27
- Object storage$8–$10
- CDN & bandwidth$2–$5
- Caching layer$60–$700
Annual maintenance
$108K – $293K/year
15–25% of build cost per year: bug fixes, iOS and Android version updates, SDK and dependency upgrades, security patching and small improvements. Cloud costs are the separate figure alongside.
Building an app like Shopify — common questions
How much does it cost to build an app like Shopify?
Using this site's default profile — 18 features, cross-platform + web app, a enterprise backend and small scale traffic — the estimate is $717,000 to $1,172,000 for a US team, or roughly 6,753 engineering hours at a blended $118–$155 per hour. That figure covers design, both apps, backend, infrastructure, integrations, security, QA, DevOps and project management. It excludes cloud hosting, vendor fees, marketing and legal. Change any answer in the calculator on this page and the number moves with it.
How long does it take to build an app like Shopify?
About 9–13 months with the team this estimate assumes — 7 people, roughly 7.0 full-time equivalents. Discovery and design run first and partly in parallel, development takes about half the calendar, and QA overlaps the back half rather than following it. A smaller team takes proportionally longer; a much larger one does not go proportionally faster, which is why compressing this schedule costs more than it saves below a certain point.
What team do you need to build an app like Shopify?
1× product manager, 1× ui/ux designer, 1× mobile developer, 2× backend developer, 1× qa engineer, 1× security engineer. That is what 6,753 hours of work distributed across 10 disciplines actually requires. The roles people most often leave out of their own plan are DevOps and QA, which together are about 15% of this build.
What does an app like Shopify cost to run each month?
Cloud infrastructure is estimated at $651 to $6,904 per month at the scale this profile assumes, driven mainly by compute and database. Third-party services add $340 to $8,000. Separately, budget $108,000 to $293,000 a year for maintenance — bug fixes, OS and SDK updates and security patching. None of these are part of the build figure.
Is a commerce platform harder than a store?
Considerably. A store serves one business; a platform serves thousands with different needs, and every feature has to be configurable. Expect 2–3× the cost of a comparable single-tenant product.
What does multi-tenancy add?
Around 150 hours for tenant isolation, configuration and billing — and a constraint on every other feature you build afterwards, which is the real cost.
