The short answer
Shopify is the right call if you need to sell products online within a few weeks and you don't have a developer on staff. You'll pay somewhere between $39 and $399 per month in platform fees, plus transaction fees if you're not using Shopify Payments, and you can have a functioning store live in days. That's genuinely useful for a lot of businesses.
A custom e-commerce build makes sense when Shopify's structure is actually fighting against how you do business. That usually shows up when you're selling configured products, quoting instead of pricing, running territory-based distribution, integrating with a legacy ERP, or needing search and filtering behavior that Shopify's templating system simply can't produce without expensive workarounds. Custom builds typically start around $10,000 to $15,000 for a real production site, and they go up from there depending on complexity.
The honest version: most small retailers should start on Shopify. Most manufacturers, distributors, and service businesses with complex catalogs or quoting workflows outgrow it. If you're unsure which bucket you're in, this page will help you figure that out.
The honest comparison
| Factor | Shopify | Custom E-Commerce |
|---|---|---|
| Time to launch | 2 to 6 weeks | 3 to 6 months |
| Starting cost | $39/mo + setup fees | $10,000 to $15,000+ build cost |
| Ongoing platform fees | $39 to $399/mo + 0.5 to 2% transaction fees | Hosting only ($50 to $300/mo typically) |
| Design flexibility | Themes with limited structural changes | Full control over every element |
| Checkout customization | Restricted (Shopify controls checkout) | Full control |
| SEO at scale (1,000+ product pages) | Workable but limited | Purpose-built if needed |
| Custom pricing / quoting | Requires expensive apps or workarounds | Built into the system natively |
| ERP / CRM integration | Via API, often complex and costly | Designed into the architecture |
| Ownership of codebase | No (you rent the platform) | Yes |
| Developer dependency long-term | Lower for basic stores | Higher unless you have internal staff |
What Shopify actually does well
Shopify is legitimately good at a specific thing: getting a standard product catalog live fast. The app ecosystem is large, the checkout is proven, and you don't need a developer to add a product, run a discount, or change a banner image. For a business selling 50 to 500 SKUs at fixed retail prices, Shopify handles 90 percent of your needs out of the box.
The hosted infrastructure is also worth something. You're not managing servers, SSL renewals, or platform security. That's Shopify's job. For a business owner who isn't technical, that matters.
Where Shopify starts costing you money
The platform fee looks small at first. It doesn't stay small. A mid-tier Shopify store, once you add the apps that fill the gaps in core functionality (advanced filtering, subscription billing, B2B pricing tiers, custom forms, better SEO tools), is realistically $500 to $1,200 per month in recurring costs before you've touched a developer. Those app subscriptions compound over time, and each one adds a point of failure.
Transaction fees are the other part most people underestimate. If you're moving $100,000 per month in product and you're not on Shopify Payments (which isn't available in every country and doesn't work with every payment processor), you're paying 0.5 to 2 percent on every dollar. That's $500 to $2,000 per month in pure fees to Shopify on top of your payment processor's cut.
What custom e-commerce actually does well
A custom-built site has no platform in the middle. The checkout behaves exactly the way your business needs it to. Pricing can be account-based, territory-based, or tied to a quote request workflow. Product pages can be structured for technical search and filtering in ways that Shopify themes don't support natively.
For businesses running programmatic SEO at scale, a custom build also gives you complete control over page structure, URL patterns, internal linking logic, and rendering. That's not something you can fully replicate on Shopify, particularly when you're talking about thousands of category or location pages.
Where custom e-commerce is the wrong answer
If you don't have ongoing developer access (in-house or agency), a custom codebase becomes a liability over time. Features don't get updated. Security patches get skipped. You end up with a site that was great in year one and a problem by year three.
Custom also takes longer and costs more upfront. If you need to start selling in four weeks, a custom build won't get you there. Shopify will. That's not a knock on either option, it's just a real constraint.
Mistakes to avoid
Choosing Shopify because it's "easier" without calculating the 3-year cost
A lot of businesses pick Shopify because the monthly fee feels low. Run the actual number: platform fee, apps, transaction fees, developer hours for theme customizations, and the cost of limitations you hit. Over three years, a $500/month Shopify setup costs $18,000 in recurring fees alone, not counting any dev work. A custom build at $15,000 with $150/month in hosting costs $20,400 over the same period, and you own the codebase. The gap is smaller than it looks, and the custom build doesn't keep charging you for functionality you already paid to build.
Assuming "custom" means unlimited budget
Custom doesn't have to mean $80,000. Scoped correctly, a custom e-commerce site for a manufacturer or distributor can be built for $12,000 to $25,000, depending on catalog size, integrations, and checkout complexity. The mistake is not scoping it at all and letting a build expand without a defined feature set. Get a written spec before anyone writes a line of code.
Using Shopify for B2B without understanding its limits
Shopify added B2B features to its Plus plan a few years back. That's the $2,000 per month tier. If you need real account-based pricing, net terms, company-level permissions, and quoting workflows, you're either on Shopify Plus or you're cobbling it together with third-party apps. Both routes are expensive. For a serious B2B catalog business, that cost often justifies a custom build.
Building custom and then ignoring ongoing maintenance
This is the most common way a custom build fails. The site gets built, it works great, and then nobody maintains it for two years. Dependencies fall out of date, a plugin stops working, and suddenly the checkout is broken. Before you go custom, budget for ongoing maintenance, somewhere in the range of $300 to $800 per month depending on complexity, or have a developer on retainer.
Switching platforms reactively instead of proactively
Don't wait until Shopify is actively hurting your business to evaluate a custom build. By the time most businesses start looking, they've already lost months of SEO equity from bad URL structures, they're paying for a stack of apps that don't play well together, and a migration is now significantly more complex. Evaluate your platform fit at 12 months, not 36.
How CodeWCG approaches this
We build custom e-commerce on a case-by-case basis, and we're honest when Shopify is actually the right answer for a client's situation. If you're a retailer with a standard catalog and no unusual pricing or integration requirements, we'll tell you that. What we focus on is businesses where the platform limitations are a real, measurable constraint: manufacturers who need to show different pricing to distributors vs. end buyers, service businesses selling configured packages, distributors with territory restrictions, or anyone who needs SEO architecture at a scale that hosted platforms can't support cleanly.
Our custom builds start at $5,000 for simpler projects and typically run $10,000 to $30,000 for full e-commerce builds with catalog management, custom checkout logic, and integration work. We're not the agency for you if you want a Shopify theme redesign. We are the right fit if you need something built specifically around how your business actually operates and you want to own the result. We run our own production site at over 193,000 indexed pages built on programmatic architecture, so when we talk about what custom infrastructure can do for organic search, that's not theoretical.
On the SEO side specifically, one of our junk removal contractor clients crossed $72,000 in a single month from organic Google traffic with zero ad spend, running on a site with over 70,000 programmatic pages indexed. That kind of output requires full control over page structure and rendering, something Shopify's template system doesn't give you. Not every e-commerce business needs that scale, but if yours does, a hosted platform will always be the ceiling.
Final answer
Shopify wins on speed and simplicity for standard retail. Custom e-commerce wins on control, long-term cost structure, and the ability to build exactly the checkout and search experience your business needs. The real question isn't which platform is better in general, it's whether your business model fits inside Shopify's guardrails or keeps running into them. If you're not sure, the answer usually shows up in your Shopify app bill and your developer's task list. If you've outgrown the platform or you're building something that needs to be designed around your actual workflow from day one, a scoped conversation about a custom build is worth your time.
