Every "best Shopify agency" list you will find is either pay-to-play or written by an agency ranking itself first. This guide does something more useful: it shows you how the agency market is actually segmented, what each segment costs, and how to pick well in an afternoon, including the case where the right agency is none.
The four kinds of Shopify agency
Design agencies. Brand, storefront design, theme builds. The deliverable is how your store looks and converts. Typical projects $10,000-50,000; see our design agency reality check.
Development agencies / companies. Custom apps, integrations, checkout work, replatforming. This is where agencies are hardest to replace; scopes from $10,000 into six figures.
Shopify Plus agencies. Certified partners for enterprise stores: checkout extensibility, multi-store, ERP integrations. Shopify's own Plus partner directory is the honest starting list; retainers commonly $5,000-25,000/month.
Full-service / growth agencies. Design + dev + marketing under one roof. Convenient, priciest, and quality varies most here because no shop is elite at everything.
How to actually choose
- Start from the directory, not from ads. Shopify's Experts Marketplace and Plus partner directory are vetted lists; Google results for "best shopify agency" are mostly listicles selling placement.
- Match the segment to your real need. A design problem taken to a development agency becomes a development invoice.
- Ask the filtering questions. "What would you change on my store first?" (specifics or pass), "Who owns the code?" (you, in writing), "Show me two live stores at my traffic level."
- Insist on itemized scope. "Website redesign - $30,000" hides the fact that half is theme build you can now generate.
The pricing reality
| Agency type | Typical engagement |
|---|---|
| Design agency project | $10,000 - $50,000 |
| Development scope | $10,000 - $100,000+ |
| Plus agency retainer | $5,000 - $25,000/month |
| Full-service retainer | $3,000 - $15,000/month |
The uncomfortable math: the design-and-build line, historically the biggest share of agency spend for non-enterprise stores, is the line AI generation collapsed. Our website cost breakdown puts the routes side by side.
Vetting: what to check before the call
Shortlists get built from marketing pages, so verify independently before you spend an hour on a sales call.
Look at their clients' live stores, not their case study screenshots. Open three on a phone. Run the theme detector on each: an agency whose portfolio is entirely premium themes with swapped colors is a configuration shop, which is fine at configuration prices.
Ask who actually does the work. Agencies subcontract, which is not a problem until nobody tells you. Ask who writes the code, in which timezone, and who you talk to when something breaks after launch.
Get the post-launch terms in writing. The build is the easy part to price. What matters six months later: who owns the code, what a change request costs, response times if the store goes down, and whether you can take the theme elsewhere. An agency that will not put those in a contract is telling you something.
Check the references they did not offer. Ask for a client whose project went sideways and what they did about it. Everyone has one. The answer separates the honest shops from the polished ones.
When you don't need an agency
- The store just needs to look custom: describe it and generate it, then spend a fraction of the agency budget on photography and brand.
- You need one developer's worth of work: hire a developer or a vetted expert, not a retainer.
- You're pre-revenue: no agency fixes an unvalidated offer; ship on a generated or free theme and prove demand first.
Agencies earn their fee at genuine complexity: enterprise integrations, multi-market operations, sustained growth programs. Below that line, 2026 gives you better options.
