Shopify development services include building and modifying your storefront, implementing or developing apps, and connecting Shopify to the systems your business uses. You might need a small change to an existing theme, a connection to a fulfilment provider or a full website design and build.
It’s a broad label, which makes it a slightly unhelpful line item on a quote. To understand what you’re buying, separate the work by what it needs to accomplish: what customers see, what functionality the store needs and how it works with the rest of your business.
Theme development: the website customers use
The theme is the frontend of your Shopify store: what customers see and interact with. Our theme development work can include setting up a purchased theme, changing its design, adding features or building a storefront around a business’s requirements.
The amount of work varies considerably:
- Theme implementation: selecting a suitable existing theme and adapting it to the business, with a defined budget for customisations.
- Theme extensions: adding or modifying features within the current theme, rather than replacing the whole website.
- Full design and build: designing the storefront and developing it from a base theme when the requirements justify that scope.
For a business launching with limited funds, we would generally start with an existing theme and targeted changes. A larger budget can accommodate a full design and build, but the requirements still need to justify the work.
For an established store, we try to extend the existing theme as far as practical. We would consider replacing it if it restricts required development or we judge that it’s causing performance problems. Wanting a new feature doesn’t automatically mean needing a new website.
Theme work can also address how easily customers find products and buy. If conversion improvement is part of the brief, agree how ecommerce conversion rate is calculated and how you’ll assess changes. A feature intended to improve the buying experience is not a guaranteed sales increase.
App implementation and custom functionality
Some requirements call for an app implementation; others suit custom development. These are different jobs, so a proposal should make clear whether the developer is configuring an existing product or building something for you.
We generally favour custom theme work for straightforward frontend features. We’ve worked with clients using separate apps for an announcement bar, cart drawer, upsell widget, hero section and navigation menu. That experience makes us cautious about adding another app for every visible feature, particularly because of our concern about the combined code added to the storefront.
That doesn’t mean we recommend rebuilding everything ourselves. We use established email and review services, and sometimes a partner such as Rebuy for cart drawers and upsells.
Budget also changes the recommendation. For a new business with limited funds, we may favour inexpensive apps and a simpler implementation. For an established business expecting to use a feature for years, we’re more inclined towards custom work that fits its requirements.
We would compare the upfront build, app fees and ongoing maintenance responsibilities before making a long-term cost claim. Custom work needs a reason beyond being custom.
Checkout changes need a separate check
A request to customise checkout needs more detail than a request to change a theme section. Shopify places plan limits on specific checkout development options.
For example, UI extensions on the information, shipping and payment pages require Shopify Plus, while some thank-you, order-status and customer-account extensions are available on Basic or higher. Public apps using Shopify Functions are available on Basic or higher; custom apps using Functions require Plus. Shopify’s checkout customisation documentation explains these distinctions.
Ask the developer to check the exact requirement against your plan. Neither “everything needs Plus” nor “we can customise anything” is an adequate answer.
Integrations: connecting Shopify to your business
Development can also happen behind the storefront. An integration connects Shopify with another system, such as a fulfilment provider, third-party logistics provider (3PL), enterprise resource planning system (ERP) or spreadsheet.
Our starting point is the process the connection needs to support. We want to establish which data must move, when it must move and which parts of the business process cannot change.
If an existing app meets those requirements, we’ll recommend it. If it would break a required process, we’d recommend custom development. The value we look for is a closer fit with how the business needs to operate.
Shopify provides tools for these connections. Its GraphQL Admin API supports reading and updating products, orders, customers and inventory, while webhooks notify an integration when store data changes. Authentication requirements and API limits still need to be considered. Shopify API documentation
Those capabilities establish what’s possible, not how simple a particular integration will be. A useful integration scope needs to describe the required behaviour, rather than just say “connect the ERP”.
What should the development proposal include?
Once you’ve identified the work, you can compare Shopify website development services on something more useful than the headline price.
For a launch, our core objective is a functional store that customers can use and buy from, with conversion considerations built into the work. The route might be theme implementation, app implementation or a full design and build. These aren’t interchangeable packages.
Whether you’re hiring a Shopify development agency or an independent Shopify developer, ask for a written scope covering:
| Area | What to establish |
|---|---|
| Deliverables | The theme changes, designs, app implementations or integrations being delivered. |
| Exclusions | What your team must supply, and what needs a separate quote. |
| Quality assurance | What will be tested before deployment and who resolves problems. |
| Post-launch support | What help is included after the work goes live. |
| Warranty | Which implementation defects are covered and for how long. |
| Ongoing responsibilities | Who maintains the work and how future changes are handled. |
We consider quality assurance and post-launch support essential. At odda, we typically offer a 7- to 14-day warranty after work goes live, covering agreed work that hasn’t been implemented properly. Confirm the applicable terms for your project.
Before requesting quotes, write down what customers must be able to do and which business processes the store must support. Ask each provider to explain what they would configure, build, defer or exclude. Then the price has a scope attached to it, and you have a basis for deciding whether the work is worth buying.
