Most “WooCommerce development agency” shortlists get built the wrong way round. Someone Googles it, opens six tabs, picks the one with the nicest homepage, and finds out four months later that the “custom store” is a $59 theme with 41 plugins bolted on.
We know because a fair chunk of our WooCommerce development work is rescuing exactly those stores.
So this list does two things. It gives you ten agencies that actually build on WooCommerce (not Shopify shops that will “do Woo if you insist”), and it tells you what to ask them, what you should expect to pay, and when a freelancer is honestly the better call. SiteMile is first on the list because it’s ours.
The other nine are agencies we’ve either competed against, inherited work from, or seen referenced enough times to trust.
What a WooCommerce agency should be good at
WooCommerce is easy to install and hard to run well. That gap is the whole reason agencies exist.
The stuff that matters, in roughly the order it bites you:
Checkout and cart logic. Conditional shipping, tax by region, deposits, subscriptions, B2B pricing tiers, minimum order quantities. Almost every real store needs at least two of these and none of them work properly out of the box. Ask the agency to describe the last checkout customization they shipped. If the answer is “we installed a plugin,” keep looking.
Performance under load. A store doing 30 orders a day and a store doing 30 orders an hour are different engineering problems. WooCommerce’s database gets slow once you pass a few thousand orders unless someone has enabled HPOS, cleaned up transients, and put real object caching in front of it. An agency that can’t tell you what HPOS is shouldn’t be building your store.
Integrations. ERPs, CRMs, fulfilment (ShipStation, ShipBob), accounting (Xero, QuickBooks), email (Klaviyo). We do a lot of this through our custom integrations and automations work and it’s consistently the part clients underestimate. Syncing inventory in two directions without double-selling is not a weekend job.
Migrations. Shopify to WooCommerce, Magento to WooCommerce, old WooCommerce to new WooCommerce. The hard part isn’t moving products. It’s keeping URLs, redirects, order history and customer accounts intact so you don’t lose rankings and annoy 8,000 existing customers on day one.
SEO baked in, not bolted on. Category structure, faceted navigation that doesn’t create 40,000 crawlable junk URLs, schema on product pages, image handling that doesn’t tank Core Web Vitals. If the agency doesn’t have an SEO person on staff, the developers will make choices that an SEO consultant has to undo later. This is why we run WooCommerce SEO as its own service alongside builds rather than as an afterthought.
Security and PCI compliance also matter, obviously, but any agency that’s been doing this for more than a couple of years will have that covered. It’s rarely the thing that separates them.
The 10 agencies
Details below are accurate as of September 2026 as far as we can tell. Clutch ratings move, people leave, agencies get acquired. Verify before you sign anything.
1. SiteMile
Based in: Romania, working with clients across the US, UK, Australia and Europe. Best for: Small and mid-size stores that need custom functionality without an enterprise price tag. Pricing: Fixed packages from $1,000, custom builds quoted per project.
Yes, we’re putting ourselves first. It’s our site.
Here’s the honest pitch. SiteMile has been on WordPress for 15+ years and has shipped 250+ projects. Before we were an agency we were a theme shop, and around 36,000 people have bought our themes, including a WooCommerce auction plugin that’s still in active development.
That background matters more than it sounds: we’ve spent over a decade supporting thousands of store owners who broke things in ways we never imagined, and every one of those tickets taught us something about how WooCommerce fails in the wild.
Today the agency side does WooCommerce store builds and redesigns, WooCommerce website design, checkout and cart rebuilds, payment gateway and shipping logic, subscriptions and booking setups, marketplace-style stores, and platform migrations. We also have an in-house SEO team, which is unusual at our size, so a store leaves us with the technical SEO already done rather than as a line item for later.
Our packages are public. The Starter store package is $1,000 and covers setup, product page work, checkout improvements and gateway configuration.
The Growth package is $1,999 and adds custom layouts, checkout flow optimization, filtering, shipping and tax logic, and performance work. Bigger builds (subscriptions, bookings, multi-vendor, heavy integrations) get a custom quote after a discovery call. After launch, WordPress maintenance plans cover updates, backups, security and speed monitoring so the store doesn’t quietly rot.
Where we’re not the right fit: if you’re a Fortune 500 with a procurement process that needs SOC 2 paperwork and a 40-person delivery team, look at 10up or Multidots below. We’re a senior team, not a large one.
You can read SiteMile reviews or get a quote if you want to talk through a project.
2. Multidots
Based in: Austin, Texas (with a London office). Best for: Enterprise and publisher-scale WooCommerce, replatforming from Magento or Shopify.
Multidots is a WordPress VIP Gold partner and an Inc. 5000 company, founded in 2009. They’re the agency you call when the store is one part of a much larger WordPress estate. Their WooCommerce work leans toward high-traffic, high-SKU stores with ERP and CRM integrations, and they do a lot of migrations off Magento and Shopify. Clutch rating sits around 4.9 from 30+ reviews. Expect enterprise pricing to match.
3. Syde (formerly Inpsyde)
Based in: Germany. Best for: European enterprises, multilingual and multisite stores.
Syde calls itself Europe’s largest WordPress agency and it’s probably true. They’re WordPress VIP Gold and Platinum WooExperts, and they’ve been around since 2006. If you need a store that runs in eight languages across four legal entities with different VAT rules, this is the kind of problem they’re built for. Overkill for a single-country DTC brand.
4. IT Monks Agency
Based in: New York. Best for: Custom themes and plugins for mid-market stores.
15+ years, 500+ projects, and a Clutch rating of 5.0 across 20 reviews, which is hard to get. IT Monks does custom WooCommerce theme and plugin development and offers ongoing maintenance. A solid US-based option if you want to stay onshore without paying enterprise rates.
5. 10up
Based in: Distributed, US-headquartered. Best for: Large brands that need a big delivery team and heavy engineering.
10up is one of the best-known WordPress agencies, period. WooCommerce is a slice of what they do rather than the focus, but their engineering depth is real and they’ve built stores for household-name brands. Not a fit for a $10k project. Very much a fit for a $300k one.
6. Kanuka Digital
Based in: Staffordshire, UK. Best for: UK B2B and B2C stores with custom integrations.
Kanuka Digital focuses on custom theme development, API integrations and performance for enterprise-ish stores. Clients include Bacofoil and Willows Veterinary Group. They offer support retainers post-launch, which matters more than people think.
7. Inspry
Based in: Atlanta, Georgia. Best for: Mid-size US stores that want audits before commitments.
Inspry has been building WordPress and WooCommerce since 2011 and does something we like: proper site audits as a standalone service, so you can find out what’s wrong before you commit to a rebuild. Clutch rating around 4.8.
8. WebDevStudios
Based in: US, distributed. Best for: Custom WordPress and WooCommerce at enterprise scale.
WebDevStudios is a long-standing WordPress VIP partner with deep plugin and platform engineering experience. Like 10up, WooCommerce is part of a broader practice, but they’ve delivered plenty of complex stores. Enterprise-level budgets.
9. Thrive Digital
Based in: Gold Coast, Australia. Best for: Australian and APAC stores, small to mid-size.
Platinum Certified WooExperts operating since 2006. They work across a lot of niches (bridal, beauty, food, tourism) and bundle branding and email marketing with development, which suits smaller brands that want one vendor.
10. Codeable
Based in: Marketplace, global. Best for: Single well-defined tasks where you don’t need an agency at all.
Codeable isn’t an agency. It’s a vetted marketplace of WordPress and WooCommerce freelancers with a fixed rate range, and it belongs on this list because for a lot of “I need one thing fixed” jobs it’s the smarter choice. More on that below.
What WooCommerce development actually costs
This is the question people search for most and the one agencies are least willing to answer publicly, so here’s a real range based on what we quote and what we see competitors quote.
A freelancer on Upwork or Codeable runs anywhere from $25/hour offshore to $80–$150/hour for an experienced US or UK developer. Fine for isolated tasks. Risky for a full build, because you’re one person’s holiday away from a stalled project.
A small or mid-size agency (us, IT Monks, Inspry, Kanuka) will typically price a store somewhere between $1,000 and $25,000 depending on scope. A clean store with a custom design, sensible checkout and a few integrations usually lands between $3,000 and $12,000. Add subscriptions, multi-vendor, or a two-way ERP sync and you’re in the $15,000 to $40,000 range.
Enterprise agencies (10up, Multidots, Syde, WebDevStudios) rarely engage below $50,000 and commonly run into six figures. You’re paying for team size, process, compliance paperwork and the ability to absorb a project that changes direction twice.
Then there’s the part nobody puts in the proposal: ongoing costs. Hosting for a serious WooCommerce store is $30 to $300+ a month. Premium plugin licenses add up fast; a store with subscriptions, a good search plugin, a shipping plugin and a page builder can easily be paying $1,000 a year in renewals. And maintenance, whether you do it yourself or pay someone, is not optional on a platform that ships security updates every few weeks. Budget 10–20% of the build cost per year for upkeep and small improvements. Anyone who tells you the store will “just run” is selling.
Agency or freelancer?
We’d love to say “always hire an agency” but that would be self-serving and wrong.
Hire a freelancer when the job is bounded and you can describe it in two sentences. “Add a deposit option to checkout.” “Fix the shipping calculator for Canadian addresses.” “Speed up the category pages.” One good developer, one week, done. Codeable or hiring a WordPress developer on a short contract both work fine for this.
Hire an agency when the job has a design phase, more than one integration, or a launch date that would hurt if it slipped. That’s when you want a project manager, a designer, a developer and someone thinking about SEO in the same room. It’s also when the freelancer model breaks down, because the person who’s great at custom checkout code is usually not the person who should be designing your product pages.
There’s a middle path, which is what our WordPress consulting service exists for: an hour with someone senior to scope the project properly before you decide who builds it. It’s cheap insurance against paying an agency for something a freelancer could do, or the reverse.
Questions that separate good agencies from theme installers
Ask these on the discovery call. The answers tell you more than the portfolio.
- “What’s your approach to HPOS and order storage on a store with 50,000+ orders?” If they don’t know what you’re talking about, they haven’t built a store that size.
- “Show me a checkout customization you wrote code for, not a plugin you configured.”
- “How do you handle redirects and URL structure on a migration?” Look for a spreadsheet, a crawl, and a 301 map. Not “we’ll sort it after launch.”
- “Who owns the code and can I take it to another developer?” The correct answer is you, and yes. Some agencies build on proprietary frameworks that lock you in. Walk away.
- “What happens in month 13?” You want a clear answer about maintenance, response times for a broken checkout, and what a small change costs after the project closes.
- “Which plugins will you install, and why each one?” A good agency can justify every plugin. A bad one has a default stack of 35 it puts on everything.
One more, slightly uncomfortable: ask to speak to a client who’s been with them for two or more years. Anyone can find a happy client from last month. Long retainers are the real signal.
Red flags we see in inherited stores
Because we take over a lot of stores other agencies built, we have a running list of things that tell us the previous team was winging it.
Elementor or WPBakery used to build product and checkout pages, which almost always kills Core Web Vitals and makes future changes miserable. Product variations handled with a plugin instead of WooCommerce’s native variable products. Category pages generating a crawlable URL for every filter combination, so Google is indexing 60,000 pages of nothing. No staging environment, so every change was tested on the live store. Custom code stuffed into the theme’s functions.php with no version control. A “custom theme” that’s a purchased ThemeForest theme with the branding swapped.
None of these is fatal on its own. All of them together mean you’re going to be paying for a rebuild, which is the situation this whole article is trying to help you avoid.
If you’re already in that situation, or you’d rather not get there, tell us about the store. A short call is usually enough to tell you whether you need a fix, a phase two, or a fresh start.
