## The short answer

How much does a Shopify build cost? A theme customization on an existing store is usually a four-figure project, a new store on a customized theme runs four to five figures, and a full custom build or migration runs five to six. Shopify's own [website cost guide](https://www.shopify.com/blog/how-much-does-a-website-cost) puts custom design and development at $1,000 to $150,000 or more, citing a 2026 GoodFirms survey, and notes that most agencies in that survey (63 percent) quoted between $1,000 and $15,000. Its [ecommerce website cost guide](https://www.shopify.com/blog/ecommerce-website-cost) gives a tighter range for typical custom-built development: $2,000 to $20,000 or more depending on complexity.

Those ranges are wide enough to be useless as a quote, and that is the honest part. "A Shopify build" covers at least four different kinds of project, and within each one the price is driven less by page count than by a handful of variables most clients never think to mention: integrations, data, stakeholders, and how settled the requirements actually are. This post breaks the number down the way an agency builds it: by project type, then by line item, then by the variables that move it, so both sides of the quote can see where the money actually goes.

## How much does a Shopify build cost by project type

The first question is the same one that drives [how long a build takes](/blog/how-long-does-a-shopify-build-take): which project is the client actually buying? The costs barely overlap.

**Theme customization on an existing store.** New sections, a redesigned product page, a navigation overhaul, built on the client's current theme. With a settled scope this is typically a four-figure engagement: days to a few weeks of design and development time at agency rates. It sits at the bottom of Shopify's $1,000-to-$15,000 band, which is where most agency quotes land.

**A new store on a customized theme.** A purchased or free theme, adapted to the brand, with app configuration, content population, and a QA pass. The theme itself is the cheap part: Shopify's cost guide puts prebuilt themes at $0 to $400 or more. The work around it, design decisions, configuration, content, and testing, is what pushes the project into the mid four figures to low five figures.

**A full custom build or redesign.** Custom theme architecture, bespoke design, and integrations. This is the territory Shopify's $2,000-to-$20,000 custom development range describes at the low and middle end, and where the long tail of its $150,000-plus ceiling lives: headless builds, multi-market storefronts, and projects with a real data layer. Five figures is the normal case; six figures means integrations and custom systems, not more pages.

**A migration or replatform.** Moving a store from Magento, WooCommerce, or a legacy platform onto Shopify or Shopify Plus. Price follows the same drivers as the timeline: the count and condition of integrations, the data model, and the number of systems attached. A mid-market migration is a five-figure project; enterprise migrations with ERP, OMS, or custom checkout logic go well beyond that, for the same reasons they take [quarters rather than weeks](/blog/how-long-does-a-shopify-build-take).

## What is inside a Shopify development cost

Clients tend to read a quote as one number for "the website." An agency that itemizes the Shopify development cost gives the client a map of where the money goes and gives itself a defensible position when scope moves.

**Platform subscription.** The smallest line, and the only one that is public. Shopify's core plans run from roughly $25 to $400 a month depending on tier and billing cycle, and Shopify Plus starts at $2,300 a month, per [Shopify's pricing page](https://www.shopify.com/pricing). It belongs in the client conversation anyway, because clients regularly conflate platform cost with build cost.

**Theme or design foundation.** $0 to $400 or more for a prebuilt theme, versus custom design measured in weeks of design time. The decision is not aesthetic, it is economic: a custom design system only pays for itself when the brand genuinely cannot live inside a well-chosen theme.

**Development.** The largest line on most quotes, and the one that varies least per hour and most per scope. The same feature can cost triple depending on whether it is a theme setting, an app, or custom code, which is why the technical check belongs before the quote, not after.

**Apps and integrations.** Monthly app subscriptions are the client's ongoing cost, but the build-side cost is the integration work: connecting the ERP, the email platform, the subscription logic, the reviews provider. Integration count predicts budget better than page count on nearly every project.

**Payment processing.** Not a build cost, but worth stating in the same conversation because it surprises clients later: Shopify Payments card rates run roughly 2.4 to 3.5 percent per transaction, per [Shopify's ecommerce cost guide](https://www.shopify.com/blog/ecommerce-website-cost).

**QA, launch, and contingency.** The line agencies most often leave implicit and then eat. Testing against acceptance criteria, launch preparation, and a contingency for the unknowns discovery flagged all belong in the number. A quote with no contingency is a statement that the scope contains no assumptions, which is almost never true.

## What actually moves the number

Across project types, a few variables explain most of the distance between a $5,000 build and a $50,000 one, and none of them is page count.

- **Integration count and condition.** Each system the store talks to adds scoping, build, and test work, and an undocumented integration found mid-project costs several times what it would have cost to find during the technical check.
- **Data.** Catalog size, variant complexity, and the state of the existing data. Clean data imports; messy data becomes a project inside the project.
- **Stakeholders and decision speed.** Revision rounds are paid for in hours. Five stakeholders with conflicting opinions do not change the scope on paper, but they can double the design and revision budget in practice.
- **How settled the requirements are.** This is the biggest one, and the least visible on a quote. A scope built on confirmed requirements prices tightly. A scope built on assumptions prices loosely or wrongly, and the gap surfaces later as change requests, overruns, or a renegotiation.

That last variable is why the pricing model matters as much as the price. A [fixed price only makes sense when the scope is genuinely bounded](/blog/fixed-price-vs-time-and-materials-shopify); quoted against an unsettled scope, it is not a price, it is a bet the agency made on the client's behalf. The [scoping process](/blog/shopify-project-scoping) is where that gets decided: separating confirmed scope from assumptions, pricing the confident core tightly, and naming the fuzzy edge instead of averaging it into one flat number.

## The cost nobody itemizes: requirements churn

There is one cost that never appears as a line item but shows up in the final spend of most Shopify builds: the cost of requirements being discovered, re-discovered, and re-translated while the project is running. A client mentions a constraint on a call and it reaches the developer three weeks later as a change request instead of a ticket. A requirement lives in a senior person's head between the meeting and the backlog, and the build that happened in between gets partially redone. None of that is development cost in the estimating sense. All of it is billed hours or eaten margin.

This is the specific cost CommerceCopilot's Business Analyst agent is built to remove. It listens where requirements actually form (client calls, connected Slack channels, meeting notes and documents), keeps a running model of what is confirmed, what is assumed, and what is still open, and proposes structured, [buildable tickets](/blog/how-to-write-development-tickets) with acceptance criteria as the picture firms up. The quote still has to be right, but the expensive gap between what was said and what was built gets much smaller, and the scoping that produced the quote runs against a live record instead of someone's memory. The [discovery project guide](/docs/your-first-discovery-project) shows what that looks like on a first project.

## FAQ

### Can a real Shopify store be built for under $1,000?

A simple store on a free theme with existing content, yes, especially if the merchant does the configuration themselves and pays only for the subscription and a few hours of help. The moment the project involves custom design, integrations, or catalog work, it moves into the agency ranges above.

### Why do two agencies quote such different prices for the same brief?

Usually because they are pricing different scopes. A brief describes an outcome, not a build, and each agency fills the gaps with its own assumptions about integrations, data, and revision rounds. The quote built on a completed technical check is usually the higher and the more accurate one.

### What does a Shopify Plus build cost compared to a standard build?

The platform difference is public: Shopify Plus starts at $2,300 a month versus roughly $25 to $400 for core plans. The build difference is driven by what Plus projects tend to involve, checkout customization, ERP and OMS integrations, and multiple markets, which is why they price like migrations and custom builds, not like store launches.

### Does AI meaningfully reduce the cost of a Shopify build?

It reduces specific line items rather than the total uniformly. The clearest savings are upstream of development: continuous discovery and automated brief-to-ticket translation cut the senior hours spent scoping, re-scoping, and translating requirements, and they shrink the rework that requirements churn causes mid-build. The development hours a feature genuinely needs still get worked; what shrinks is the spend around them.
