How to choose a Shopify agency for your project

October 5, 2026

A guide to comparing Shopify agency proposals: what to request, what to check in case studies and what to agree before starting.

To choose a Shopify agency, define what needs changing and request evidence that the team can handle that kind of project. A good portfolio helps, but you also need to know who will do the work, what you can edit afterwards and how delivery will be checked.

A migration involving data and integrations, a brand redesign and conversion work solve different problems. Comparing all three as “building a website” often omits what later delays the project. This guide helps you request proposals you can meaningfully compare.

First, name the work you need

Project type changes what you should expect from an agency
Your situation	Service to explore	What the proposal should clarify
Your platform no longer meets your needs and you want to move	Shopify migration	Data, URLs, integrations, validation and launch plan
The store works but poorly represents the brand or makes purchasing difficult	Shopify design and redesign	Navigation, product pages, mobile, states and design implementation
You need a missing function, theme or connection	Shopify development	Architecture, compatibility, testing, editing and maintenance
You have traffic and want to improve purchasing	Shopify CRO	Data quality, identified problems, priorities and measurement
You do not yet know where the problem lies	Audit or consulting	What will be analysed and which decision or deliverable you receive

Several needs can coexist. Agree which constrains the others. If catalogue data is not ready, designing every product page first may require reworking them. With incomplete measurement, promising a conversion improvement you cannot verify makes little sense either.

Request cases with similar complexity, not just the same sector

A store in your sector is a useful reference, but insufficient alone. Its catalogue may have been simple while yours depends on bundles, subscriptions or an ERP. Ask what the agency actually did and which problem it resolved. A final screenshot does not prove who designed, developed or produced the change's results.

A documented case should distinguish starting point, team scope, decisions and delivery. If sales or conversion figures appear, request period, source and context: campaigns, price changes and seasonality can influence them. Customer reviews add another perspective but do not replace those data.

To review our work, start with our case studies and opinions on our official Shopify profile. Assess scope through documentation rather than attributing every store activity to one provider.

Check what Shopify accreditation means

The official Shopify directory helps find and contact professionals. Confirm the profile and website refer to the same company, review services and read opinions with their dates and context.

Accreditation signals an ecosystem relationship, not guaranteed sales, deadlines or freedom from incidents. Confirm project fit too. Migration expertise alone does not demonstrate acquisition capability; equally, a successful campaign does not prove complex technical development skills.

Questions that make two quotes comparable

What exactly is included? Ask for pages, features, languages, integrations and content migration. “Complete design” admits too many interpretations.
Who participates? Clarify design, development and coordination roles and who makes decisions with you. Know if third parties are involved.
What must we provide? Photos, text, catalogue and access are part of the schedule. A deadline without those dependencies says little.
What can we edit? Request everyday changes in a test store: a section, mobile image, product or reusable block. Shopify templates, sections and blocks provide that editing when properly implemented.
How is it tested? Review should cover devices and journeys important to your store, not only visual presentation.
What remains at handover? Agree access, files, licences, documentation and editor training. Distinguish incident corrections from later changes.

Compare the cost of maintaining the solution

Beyond the initial budget, ask about subscriptions and dependencies: theme, apps, connectors, external services and maintenance. Separate necessary from optional costs and identify who owns every account.

Custom functionality can avoid an app but still needs maintenance. An app may solve a need quickly but must fit your data and tools. The lowest price is comparable only when scope and ongoing costs are comparable too.

Signs to pause and clarify the proposal

Sales or SEO positions are promised without explaining measurement or dependencies.
The portfolio obscures the team's role or mixes others' results with its own.
The project depends on access or licences outside your control.
Design is approved only on desktop, leaving mobile until last.
No acceptance criteria or agreed scope-change process exists.

These signs call for a specific conversation. A brief quote can suit a small task; problems arise when it omits decisions necessary for a large project.

A simple brief to send agencies

Prepare your store URL, problem, essential features, connected systems, internal decision-makers and any critical date. Add visual references with explanations of what appeals and why it helps customers. If the solution is unclear, say so rather than fixing technology before diagnosis.
