Shopify and Shopify Plus Implementation Cost: What Drives the Budget?

Shopify is a SaaS platform, so the cost of launching a store looks easy to predict. The platform provides the ecommerce infrastructure and plenty of features you can use without writing code. Even so, the amount of work behind individual implementations varies enormously.

A small store on an off-the-shelf theme, with basic configuration and a short catalogue, can be up and running in a few days. A full implementation for a company with complex processes, integrations and its own UX requirements takes several hundred hours.

Below we show how much a Shopify implementation costs in smaller, typical and more complex Hyper Effekt projects, where the differences come from and what an implementation estimate does not cover.

How do we price Shopify implementations?

We run implementation projects on a time & materials basis, which means we bill for the work actually done. Before the project starts, we prepare an estimate that helps forecast the number of hours and plan the budget. The final cost depends on the time spent on the agreed scope. The calculations in this article assume a rate of PLN 220 net per hour. Our current rates are published on the About us page.

Fixed price works well for small, precisely defined tasks. In a larger implementation, some decisions and dependencies only surface once work is under way, so it is hard to set a single price up front. Other agencies may offer a fixed price or a hybrid model.

The billing model alone does not determine the final budget. What matters more is what the estimate covers, how thoroughly the scope has been described and at what stage of the project the estimate was prepared.

How much work does a Shopify implementation require?

In our projects, effort and cost fall within the ranges below. The amounts cover the work from design to store launch. They do not include ecommerce architecture, which we bill separately, or platform and app fees. We cover those fees in our article on Shopify pricing and TCO.

The most complex migrations can exceed 600 hours.

The spread comes down to scope. In a larger implementation, you have to decide how the store should work, design the key views and technical solutions, build them, test them, fix what needs fixing and get the store ready to sell. On top of that come communication, project management and decisions made together with the client.

Every feature has to be built, connected to the rest of the store and checked in the relevant scenarios. When a test reveals a problem, the team looks for the cause, prepares a fix and checks it again. And if a need can be met in several ways, someone still has to judge which solution will make sense once the store is live.

In a typical project, the hours are split between design, theme development, Shopify configuration, integrations, testing, launch and project management. The proportions are different every time. In one store the frontend takes the most work, in another it is the integration with an external system. In a migration, cleaning up and restructuring data can take up a large part of the project.

When preparing a first estimate, it is tempting to start by counting products and pages. That shows how much content needs to be created or moved, but says nothing about the complexity of features, integrations or the state of the data. A store with a short catalogue and unusual sales logic may need more work than a store with a large, well-organised catalogue that relies on standard Shopify features.

From an initial range to a detailed estimate

If the client can describe their needs fairly precisely, we can usually give an indicative effort during the first call. A store on a modified theme that mainly uses standard Shopify features will probably fall within our typical range of 250–350 hours, or PLN 55,000–77,000 net.

A range like this lets you quickly check whether the planned budget is realistic and gives you a reference point when comparing the first proposals. It is still based on initial assumptions, though, not on a delivery plan.

A more accurate estimate follows once the ecommerce architecture is in place. As part of that work, we run discovery workshops, organise the requirements and prepare an implementation plan.

In the workshops, the initial idea turns into a description of a solution that can actually be built. Sometimes a feature considered essential can be replaced with something simpler. At other times, a seemingly minor requirement brings an extra integration, a change to the data model or work on the side of an external vendor.

Once the architecture is ready, we break the project down into areas and tasks. In one of our plans, three of the areas looked like this:

The hours in each area are the sum of the time assigned to specific tasks. The client can see what work we have included and how much time we have allowed for each element. The same document included tasks such as these:

These are examples from the areas shown above, not additional items to add on top. The full plan also covers testing, launch, project management and the remaining tasks. A breakdown like this shows which requirements have the biggest impact on the number of hours. It also makes it easier to update the estimate when the scope changes before or during the implementation.

What has the biggest impact on Shopify implementation cost?

The most hours usually go into anything that goes beyond Shopify's standard features. Every custom mechanism has to be designed, built, connected to the rest of the store and tested in different scenarios.

The extent of theme and app customisation

An off-the-shelf theme from the Shopify Theme Store can reduce the number of hours if its architecture is close to what the brand needs. If the changes affect most of the key sections and features, however, the initial saving quickly disappears. In that case, building a custom theme is often the more sensible option.

The choice between an app and a custom solution works in a similar way. An app means a subscription. A custom equivalent, on the other hand, requires design, development, testing and ongoing maintenance. In a new store, it often makes sense to start with an existing app, see how the feature works in practice and only then decide whether a custom solution is worth the extra cost.

Integrations with external systems

Shopify is often just one of several systems a company uses. Orders, products, prices, stock levels and customer data may flow between the store and an ERP, an OMS, a PIM, an order fulfilment system or other tools.

The cost of an integration depends on the number of systems, the quality of their APIs and documentation, the data model and the processes that need to be replicated. The division of responsibilities matters too. A Shopify agency's estimate may cover only the work on the store side, while the vendor of the external system prices its part of the connection separately.

Data that needs cleaning up before a migration

If the catalogue is well organised and can be mapped to Shopify without major changes, a migration is fairly predictable. Things get complicated when the quality of the data needs improving or its structure needs changing along the way.

Let's say that in the old store the entire product description sits in a single field. In the new store, ingredients, directions for use, technical specifications and additional information are to be stored separately and displayed in different places on the product page. An import alone will not do the job. The data has to be split, organised and sometimes supplemented with information that simply did not exist before.

With a large catalogue, this work can cost more than setting up the import itself.

Does Shopify Plus mean a more expensive implementation?

In our experience, Shopify Plus implementations are often more expensive, but not because of the plan itself. What makes the difference is the profile of the companies that choose it and the complexity of their projects.

They are usually larger organisations with higher online sales. They are more likely to be migrating from an existing platform than building their first store. They have processes, integrations and features that need to be recreated, redesigned or replaced with something else. They also more often opt for a custom theme and need mechanisms tailored to their own organisation.

Most full Shopify Plus implementations at Hyper Effekt fall roughly within the range of 250–400 hours, or PLN 55,000–88,000 net. The most complex migrations can take more. With a different provider and a different scope of work, these figures may look different.

For the estimate, the subscription plan matters less than what the store has to do, which processes it needs to support and what environment the company is starting from.

What does an implementation estimate not include?

When comparing budgets, it is worth checking what the word "implementation" actually means in a given proposal. Two agencies may quote a similar number of hours and still mean a different scope of responsibility.

At Hyper Effekt, the implementation estimate does not include ecommerce architecture. That stage comes before delivery and we bill it separately, at a fixed price.

Nor does it include the time of the client's team. Projects often involve an Ecommerce Manager, the ecommerce team, marketing and agencies responsible for advertising, SEO or creative work. How much work that means depends on the organisation and the project, so it is worth including it in the budget as a separate item.

Copy, photos and other assets, data entry and the work of vendors integrating the ERP, OMS or logistics may also fall outside the estimate. When we connect Shopify to another company's system, our hours cover the work on the Hyper Effekt side. The external vendor may bill its part separately.

The costs of the Shopify ecosystem need to be calculated separately too: the platform subscription, apps, payment fees and external systems. They are not part of the agency's estimate. How to calculate them and set them against the implementation cost over several years is shown in our article How Much Does Shopify Cost? Pricing, Fees and a Worked TCO Example.

How to compare quotes from Shopify agencies?

The hourly rate alone does not tell you what the project will cost. A lower rate with more hours can result in a higher budget than a higher rate with less effort. And the number of hours alone does not answer the question of whether two companies have quoted for the same work.

That is why the scope is the first thing to compare. Do both proposals include UX design? Who is responsible for store configuration and testing? Is project management included in the estimate? Who prepares and checks the data? Where does the agency's responsibility end and the work of the client or external vendors begin?

The moment the estimate was prepared matters as well. A figure given after the first call rests on more assumptions than a document prepared after the workshops, with the solution broken down into specific tasks. Initial ranges are still needed, though. They help you gauge the scale of the investment and decide whether it is worth moving on to detailed planning.

Where to start with a Shopify implementation estimate?

Start with as precise a description as possible of what needs to be implemented: the features, integrations, state of the data, scope of design work and how far the store can rely on Shopify's standard features. The better the scope is described, the more useful the estimate, both for planning the budget and for comparing proposals.

Tell us about your project. If the scope is reasonably clear, we can give you an indicative effort as early as the first call.
