Key takeaways
- A small-business online store costs $3,000–$25,000 to build in 2026 — but the build is only half the story. Year-one total cost of ownership (platform fees, apps, transaction cuts, maintenance) often adds another 30–50%.
- Shopify is cheapest on day one and keeps charging forever; WooCommerce/custom costs more to build and less to run at scale. The crossover point sits roughly around $1M in annual revenue.
- The app stack is the silent budget killer: a serious Shopify store runs $200–$1,000+/month in apps that nobody puts in the launch quote.
- Compare quotes on scope, never on the bottom line. A quote with no data-migration plan, no app inventory, and no maintenance terms isn't cheaper — it's incomplete.
- Start small and stage your spend: validate with a template store ($2k–$10k), reinvest once the money is real.
Ask five agencies what an online store costs and you'll get five numbers between $2,000 and $250,000. They're all technically right, which is why the answer feels useless.
An online store isn't one product. It's a weekend Shopify theme — and it's also a seven-figure B2B platform with ERP sync. Those are different universes, and lumping them together is how founders end up either wildly overspending or hiring the cheapest quote and rebuilding a year later.
This is the honest breakdown we'd give you over a call: what stores actually cost to build in 2026, the year-one numbers nobody puts in the headline, when to DIY, and how to read a quote without getting burned.
The short answer: cost by build type
If you want one table to anchor your budget, this is it. These are design + development numbers that hold across the industry in 2026 — not sales-sheet fantasy.
| Build type | Typical cost | Timeline | Best for |
|---|---|---|---|
| DIY / template store (Shopify theme, Wix) | $500–$3,000 | 1–4 weeks | Testing whether anyone will buy |
| Professional theme-based store (customized Shopify/WooCommerce) | $3,000–$15,000 | 3–8 weeks | Most small businesses that are past the testing stage |
| Semi-custom store (branded design, custom features, apps, SEO) | $10,000–$30,000 | 6–12 weeks | Growing brands outgrowing a template |
| Fully custom build | $40,000–$150,000 | 4–9 months | Genuinely unusual workflows, full ownership |
| Marketplace / multi-vendor | $30,000–$100,000+ | 4–12 months | Platforms where other people sell |
| Enterprise / headless | $100,000–$250,000+ | 6–18 months | High volume, complex operations |
If you're a small business, your honest range is the top three rows: $3,000–$30,000. Our own Store builds at Lynxwell start from $9k — right in the semi-custom band — and you can see exactly what's in that band on our pricing page.
The single most expensive mistake we see: going custom before you've proved people want the product. A $50k custom store that tests an unvalidated idea is just a very expensive way to learn what a $3k Shopify store would have taught you.
The year-one number nobody puts in the headline
The build quote is the part everyone talks about. The total cost of ownership is the part that surprises people six months after launch. Here's the honest all-in math for a typical small store doing ~$300k/year in sales:
| Ongoing cost | Shopify (Basic) | WooCommerce | Custom build |
|---|---|---|---|
| Platform / hosting | $468/yr ($39/mo) | $240–$3,600/yr (you host it) | $500–$2,000/yr (your server) |
| Apps / extensions | $2,400–$12,000/yr | $600–$3,000/yr | $0 (built-in) |
| Payment processing | ~2.9% + 30¢ per sale (~$8,700/yr on $300k) | ~2.9% + 30¢ per sale | ~2.9% + 30¢ per sale |
| Domain + SSL | $10–$50/yr | $10–$50/yr | $10–$50/yr |
| Maintenance, updates, security | Included (Shopify handles it) | $1,200–$4,800/yr or 10–20% of build | $3,000–$8,000/yr |
| Year-one all-in (typical) | ~$12,000–$25,000 | ~$11,000–$20,000 | ~$14,000–$21,000 |
Two things jump out:
1. Apps are the silent killer. Nobody puts "your subscriptions will cost $600/month" in the launch quote, but the average serious Shopify store runs $200–$1,000+/month in apps — reviews, loyalty, bundles, shipping, email. Before signing anything, demand an app inventory with monthly costs. If an agency can't give you that list, their quote is incomplete.
2. Payment processing dwarfs everything. On $300k of sales, 2.9% is nearly $9k a year — more than most platform and hosting costs combined. Shopify's own Shop Pay / Shopify Payments rates, WooCommerce's Stripe fees, negotiated rates at volume — this deserves more attention than the theme color. Every percentage point you negotiate or lose is real money, forever.
Shopify vs WooCommerce vs custom: the real trade-off
We've built on all of them. Here's the honest version, without the platform cheerleading:
- Shopify is the fastest path to selling. $39–$399/month platform fee, everything hosted, checkout that converts out of the box. The tax you pay: platform fees forever, app rent forever, a cut of every sale, and limited control. Brilliant until about $1M in revenue; past that, the monthly math starts favoring ownership.
- WooCommerce (on WordPress) has no platform fee and no per-sale cut, and you own everything. The tax: you own the maintenance too — updates, security, backups, the things Shopify does while you sleep. Right call if you already run WordPress or plan serious content marketing alongside the store.
- Custom (Next.js, Laravel, headless) makes sense only when no platform fits: B2B pricing rules, multi-warehouse logic, unusual fulfillment. The crossover we use as a rule of thumb: under ~$1M in annual revenue, Shopify usually wins on total cost. Past that, especially with complex needs, a custom build tends to overtake it within 18–24 months.
The pattern every honest developer will confirm: hosted platforms cost less to start and more per month forever. Open-source and custom cost more to build and less to run at scale. Where you cross over depends on your revenue — and it's worth modeling before you commit.
If platform choice is your big question, we've already done the deeper comparison in our Shopify vs WooCommerce guide — it walks through which store types fit which platform.
Should you just DIY it?
Honest answer: sometimes, yes. An agency telling you otherwise is selling you something.
DIY when:
- You're testing a product idea and have under ~50 products. A weekend on Shopify with a decent paid theme ($180–$350) and Stripe gets you selling for under $1,000 all-in.
- Your products are simple — no configurators, subscriptions, or B2B pricing tiers.
- You're comfortable doing product photography and writing your own descriptions (you should be — this is your product knowledge).
Hire when:
- You're migrating an existing store with products, customers, order history, and SEO equity. Migration is where DIY stores die — broken redirects, lost rankings, missing customer data. The rescue jobs in our inbox are almost always DIY migrations gone wrong.
- Your theme is fighting you. Custom checkout logic, subscriptions, wholesale tiers, marketplace integrations — these are developer territory.
- The store is already doing real revenue and the template is visibly costing you sales. At that point, a professional rebuild pays for itself in conversion lift.
The staged playbook we recommend to every small business: validate with a template store ($2k–$10k), prove the demand, then reinvest profits into the semi-custom build ($10k–$30k) that carries you through your growth years. Skip the middle step and you're gambling; skip the upgrade and you're leaving money on the table.
How to read an ecommerce quote like an insider
Two quotes for the "same" store can differ by 3x, and the cheaper one is frequently the more expensive one once the change orders start. When you're comparing quotes, compare scope, not the bottom line. Here's what a complete quote contains — and what's a red flag when it's missing:
- A platform recommendation with reasoning. "We'll build it on Shopify because…" If there's no reasoning, they build everything on one platform regardless of fit.
- An app/plugin inventory with monthly costs. Every paid app, what it does, what it costs per month. No list = hidden $600/month surprise.
- A product-data plan. Who cleans your messy spreadsheet of 400 SKUs, and what does that cost? Dirty product data is the #1 hidden cost in store builds, and agencies that don't mention it will bill you for it later.
- Migration scope. Products, customers, orders, URLs, redirects, reviews — itemized, not "migration included."
- Ownership terms. You should own the store, the domain, the code, and the admin accounts from day one. Any quote vague on this is a trap.
- Post-launch terms. What's the warranty period? What's the monthly maintenance cost? A store is infrastructure you run, not a brochure you build once — budget 10–20% of build cost per year.
Red flags that mean "walk away":
- A quote that's a single number with no line items.
- "Unlimited revisions" — a promise nobody can keep, which means they'll keep nothing else either.
- No staging environment mentioned. Professionals test on staging; amateurs test on your live store.
- The agency's own site is slow, broken, or hasn't been updated in years.
- They can't show you a store they've built in your rough category. Not identical — adjacent is fine.
A quote with no app inventory, no product-data plan, no migration scope, and no maintenance terms is not a cheaper quote. It's an incomplete one — and the missing parts will be invoiced later.

What it costs with us (since you'll ask)
We build stores in the semi-custom band: a professional Shopify or WooCommerce store, branded design, clean product setup, conversion-minded checkout, basic SEO, analytics wired up — from $9k. That covers the build. We'll also hand you the app inventory, the year-one cost projection, and the maintenance options before you sign anything, because we'd rather you know the full number than discover it.
And if you're not ready for a build at all, that's fine — run your existing site through our free audit and we'll show you what's leaking sales for free. Stores that are already live usually have cheaper fixes than a rebuild.
The bottom line
A small-business online store costs $3,000–$30,000 to build in 2026, and the honest year-one number — apps, fees, processing, maintenance — is usually 30–50% above the build quote. The founders who budget well do three things: stage their spend (validate first, invest after), demand the full scope in writing (app inventory, data plan, ownership, maintenance), and model the platform crossover before they commit.
Do those three and the store becomes what it should be: infrastructure that pays for itself, not a surprise bill every quarter.
