“Shopify agency” gets used as a catch-all term for anything from a two-person design studio to a large multi-discipline team running enterprise Shopify Plus builds. If you’ve never worked with one before, it’s genuinely unclear what you’re actually paying for, is it just website design? Do they write code? Do they handle marketing too?
This post breaks down, in plain terms, what a Shopify agency actually does, the different services that typically fall under that umbrella, and how to tell what you actually need versus what’s being sold to you.
The Short Answer
A Shopify agency helps merchants build, improve, migrate, and grow stores built on the Shopify platform. That can mean design and development, but a full-service agency usually goes well beyond just building a website, covering technical setup, integrations, SEO, conversion optimisation, and ongoing support.
The specific mix varies a lot between agencies. Some are development-focused generalists. Some specialise narrowly (SEO-only, or Shopify Plus enterprise builds only). Understanding the breakdown below helps you ask the right questions about what a specific agency actually offers.
The Core Services Under “Shopify Agency”
Store design and development
Building or redesigning your storefront, theme selection or custom theme development, page layouts, product and collection page structure, mobile responsiveness, and the overall buying experience. This is what most people picture first when they think “Shopify agency,” but it’s usually only one part of a broader offering.
Platform migrations
Moving a store from another platform (WooCommerce, Magento, BigCommerce, Squarespace, and others) onto Shopify, or moving from standard Shopify to Shopify Plus. This involves data migration, redirect mapping to preserve SEO, theme rebuilding, and testing, a genuinely technical process where mistakes can cost lost rankings or broken functionality.
SEO
Technical SEO (site structure, page speed, indexation, structured data), on-page optimisation, and content strategy specific to how Shopify handles URLs, collections, and metadata, which differs in real, technical ways from a generic WordPress or custom-built site.
Conversion rate optimisation (CRO)
Analysing and improving how well your existing traffic converts, checkout friction, page layout, trust signals, product page structure, rather than just driving more visitors to a leaky funnel.
App and system integrations
Connecting Shopify to the other systems your business runs on, accounting software (Xero, MYOB), ERP systems, freight and fulfilment (Australia Post, Starshipit), CRM, loyalty and reviews platforms, and payment methods like Afterpay or Zip.
Email marketing
Setting up and running lifecycle and campaign email through platforms like Klaviyo, abandoned cart flows, welcome series, post-purchase sequences, tailored to your Shopify customer and order data.
Paid media
Managing Google Ads and Meta Ads specifically for Shopify stores, including the tracking and attribution setup needed to actually measure what’s working.
Analytics and tracking
Setting up GA4 and conversion tracking correctly on Shopify, which has its own quirks (checkout tracking, server-side events) that generic analytics advice often misses.
Ongoing support and maintenance
Bug fixes, small improvements, app updates, theme updates, and general “keep the store running well” work, usually structured as a retainer rather than a one-off project.
B2B and wholesale development
Setting up company accounts, tiered pricing, and wholesale-specific workflows for merchants selling to other businesses, not just consumers.
What a Shopify Agency Doesn’t Typically Do
Being clear-eyed about scope matters. Most Shopify agencies aren’t:
- A full branding or logo design studio (some offer this, many don’t, it’s often adjacent, not core)
- A generalist marketing agency covering channels unrelated to your Shopify store
- A warehousing, fulfilment, or logistics provider (they integrate with these systems, but don’t operate them)
- A legal or accounting service, even though they might help configure GST settings or connect Xero
If an agency is proposing to handle something well outside Shopify-specific expertise, it’s worth asking how much of that work is genuinely in-house versus subcontracted.
How Engagements Are Typically Structured
- One-off projects, a defined build, migration, or redesign with a start and end date
- Retainers, ongoing monthly work, either a fixed scope of hours or a defined set of deliverables, for continuous improvement or support
- Consulting engagements, advisory work where the agency helps you plan or troubleshoot without necessarily doing all the execution themselves
Many merchants start with a project and move into a retainer once the initial build is live and needs ongoing iteration, rather than treating the store as “finished” after launch.
How Agencies Typically Work With You Day to Day
Beyond the list of services, it’s worth understanding what actually happens once you’re engaged with an agency, since this varies from what a lot of first-time clients expect:
- Discovery and scoping. A proper agency starts by understanding your actual problem and goals, not just taking a feature list and quoting it, this stage often reshapes the brief before any work begins.
- A project or account lead as your main point of contact. Rather than talking to every specialist directly, most agencies assign someone to coordinate across the team and keep you updated, so you’re not chasing multiple people for status.
- Defined check-in points. Regular updates, weekly calls, a shared project board, or milestone reviews, rather than radio silence until a big reveal at the end.
- A QA and testing phase before anything goes live. Good agencies test across devices, browsers, and, for anything involving checkout or B2B, different account and permission scenarios before handover.
- A handover or training step. You should come away understanding how to use what’s been built, not just receiving a finished product you can’t confidently update yourself.
How to Evaluate Whether an Agency’s Claimed Expertise Is Real
Because “Shopify agency” is a loosely used term, it’s worth probing a little rather than taking a homepage’s claims at face value:
- Ask about specific, technical Shopify concepts relevant to your project, Liquid, metafields, checkout extensibility, the differences between Shopify and Shopify Plus, and see if the answers are concrete or vague.
- Ask how many Shopify-specific projects (not general web projects) they’ve delivered recently, and in what categories relevant to you.
- Ask what Shopify Partner tier or certifications, if any, they hold, not a guarantee of quality on its own, but a data point.
- Ask directly what they’d flag as a risk or concern in your specific brief, a genuinely experienced team will usually spot something worth raising rather than agreeing enthusiastically with everything.
How to Tell What You Actually Need
Before engaging an agency, get specific about your actual problem:
- Is this a build problem (you need a new or redesigned store)?
- Is this a traffic problem (you have a good store but not enough visitors, SEO or paid media)?
- Is this a conversion problem (you get traffic but it doesn’t convert)?
- Is this an operational problem (integrations, order management, ongoing bugs)?
- Is this a growth problem (you’re outgrowing standard Shopify and need Plus, B2B, or more complex infrastructure)?
Most merchants have some blend of these, but naming the primary one first makes it much easier to have a productive first conversation with an agency, and to tell whether their proposed scope actually matches your real problem. If you’re not sure yet, working with Shopify consulting as a starting point can help diagnose the actual issue before you commit to a larger build.
Signs You’ve Outgrown DIY and Genuinely Need Outside Help
There’s no single trigger, but a combination of these is usually a reliable signal:
- You’re spending more time troubleshooting technical issues than running your actual business
- A DIY theme customisation or app combination has started causing conflicts or bugs you can’t confidently resolve
- You’re leaving revenue on the table through slow pages, poor mobile experience, or checkout friction you don’t know how to fix
- You’re considering a migration, a Shopify Plus upgrade, or a B2B build, all higher-stakes projects where mistakes are costly to unwind
- Your organic traffic or conversion rate has plateaued and you don’t have a clear technical explanation why
None of these mean you need to hand over your entire store to an agency immediately, often the right first step is a smaller, contained engagement (an audit, a consulting session, a single project) to establish whether outside expertise actually moves the needle before committing to something larger.
FAQs
Do I need an agency, or can I run my Shopify store myself?
Plenty of merchants run simple stores themselves successfully, especially early on. Agencies typically add the most value once complexity increases, custom development needs, integrations, SEO at scale, or when your own time is better spent running the business than troubleshooting technical issues.
How is a Shopify agency different from a general web design agency?
A Shopify-specialist agency understands the platform’s specific architecture, theme structure, Liquid, checkout limitations, Plus-specific features, app ecosystem, in a depth a generalist agency usually doesn’t have, which matters for anything beyond a very simple site.
Can an agency just do one part of what’s listed here, like SEO only?
Yes, many agencies specialise rather than offering the full list, and that’s a legitimate model if you need deep expertise in one area rather than broad coverage.
How do I know if an agency actually knows Shopify well, versus generic ecommerce?
Ask specific, platform-level questions, how they handle Liquid theme customisation, their experience with Shopify Plus versus standard, how they’ve approached a migration or B2B setup. Vague, platform-agnostic answers are a signal to dig further.
What’s the first step if I don’t know exactly what I need?
A diagnostic conversation or audit is usually more useful than jumping straight into a proposal, it identifies the actual problem before committing budget to a solution that might not be the right one.
Not Sure Where to Start?
If you’re trying to work out what your store actually needs, a strategy call is a low-commitment way to get a clear, honest read on your situation before deciding on scope or budget.
