What an Ecommerce Website Costs: The Short Answer
An ecommerce website costs anywhere from about $500 for a DIY store on a hosted platform to $25,000 or more for a custom build with integrations. Most small businesses launching a professionally built store spend $1,500-$8,000 upfront and $100-$500 per month in platform fees, apps, hosting, and maintenance, plus roughly 2.9% of every sale in payment processing.
That range is wide because "ecommerce website" covers everything from a ten-product Shopify store run from a kitchen table to a 5,000-SKU catalog synced to a warehouse. This guide breaks the cost into its parts so you can see where your money actually goes and where it makes sense to spend more or less.
The Five Costs That Make Up an Online Store
Every ecommerce budget, no matter the size, is made of the same five pieces. Prices below are typical ranges at the time of writing.
1. Platform Fees
The platform is the software that runs your catalog, cart, and checkout. You either rent it monthly (hosted platforms) or install it on hosting you pay for (self-hosted).
| Platform | Typical monthly cost | What's included | Watch for |
|---|---|---|---|
| Shopify | ~$39/mo (Basic) up to ~$399/mo (Advanced) | Hosting, security, checkout, support | Extra transaction fee if you don't use Shopify Payments; app costs |
| WooCommerce (WordPress) | Plugin is free; hosting $10-$100/mo | Full control, no platform lock-in | You handle updates, backups, and security; extensions add up |
| BigCommerce | ~$30-$40/mo (Standard) and up | Hosting, no extra transaction fees, more built-in features | Higher tiers kick in as annual sales grow |
| Squarespace Commerce | ~$36-$50/mo | Design templates, hosting, simple checkout | Fewer advanced ecommerce features; transaction fees on lower tiers |
| Wix eCommerce | ~$30-$40/mo | Easy setup, hosting included | Harder to migrate away later; SEO flexibility is limited |
| Custom / headless build | Hosting $20-$200+/mo | Exactly what you need, nothing else | Requires a developer to build and maintain |
For a starter store, the platform fee is the smallest part of the bill. It only becomes a major line item at higher tiers or once you factor in the apps needed to fill gaps.
If you're weighing platforms more broadly, our comparisons of WordPress vs Wix and Webflow vs WordPress cover the same tradeoffs from a general website perspective.
2. Design and Build
This is where the range explodes. The build cost depends on who does the work and how much of it is custom.
- DIY on a template: $0-$300 for a premium theme, plus 40-100+ hours of your time setting up products, pages, shipping rules, and taxes.
- Freelancer: $1,500-$8,000 for a store on Shopify or WooCommerce with a customized theme, product setup, and basic SEO. Quality varies enormously.
- Boutique agency or specialized firm: $3,000-$20,000 for a structured process with design, development, product page SEO, and conversion work.
- Large agency or custom platform build: $20,000-$100,000+ for fully custom design, ERP or inventory integrations, and multi-channel selling.
Two things push the build cost up faster than anything else: the number of products (each one needs a title, description, images, variants, and pricing) and custom checkout logic (subscriptions, bundles, wholesale pricing, or configurable products).
At Built For Rank, ecommerce projects start from our $1,500 base build. Product catalog size, payment integrations, and custom functionality are quoted on top of that, and we tell you the number before any work starts.
3. Payment Processing
This is the cost people most often forget, and it scales with your success. Card processors and platform payment systems typically charge around 2.9% plus $0.30 per online transaction. PayPal, Buy Now Pay Later options, and international cards can run higher.
On $10,000 in monthly sales, that's roughly $290 plus per-order fees before you've paid for anything else. Some platforms add their own transaction fee (often 0.5%-2%) if you use an outside payment gateway instead of their built-in one, so read the fine print on whichever tier you pick.
4. Apps, Extensions, and Add-Ons
Templates and platforms cover the basics. Everything beyond the basics tends to be an app with a monthly fee:
- Reviews and social proof: $0-$50/mo
- Email and SMS marketing: $0-$100+/mo (scales with list size)
- Shipping labels and rate calculators: $0-$50/mo
- Sales tax automation: $0-$50/mo (more once you have nexus in several states)
- Upsells, bundles, and subscriptions: $10-$100/mo
- Advanced SEO, redirects, and schema: $10-$40/mo
- Accounting sync (QuickBooks, Xero): $10-$40/mo
A starter store might get by with two or three apps at $30-$60 a month. Established stores frequently carry ten or more and spend $200-$500 a month on apps alone. Audit these once a quarter; app creep is real.
5. Ongoing Costs
Beyond the platform and apps, an online store keeps costing money after launch:
- Domain: $10-$20/year
- Hosting (self-hosted only): $10-$100/mo depending on traffic and performance
- Maintenance: $50-$500/mo for updates, security, backups, and small changes
- Product photography: $25-$75 per product for professional shots, or a one-time investment in a lightbox setup
- Content and SEO: $250-$2,000+/mo if you want organic traffic to grow (see our SEO pricing guide for what that money should buy)
- Paid ads: optional, but most stores spend something on Google Shopping or social ads, especially early
Ecommerce Website Cost by Store Size
Here's how those five pieces add up for three typical stores. These are planning ranges, not quotes.
| Cost | Starter (under 50 products, DIY or small build) | Growing (50-500 products, professional build) | Established (500+ products, custom features) |
|---|---|---|---|
| Platform | $0-$40/mo | $40-$105/mo | $105-$400+/mo |
| Design and build | $0-$1,500 | $1,500-$8,000 | $8,000-$50,000+ |
| Apps and extensions | $0-$60/mo | $60-$200/mo | $200-$600/mo |
| Payment processing | ~2.9% + $0.30/order | ~2.9% + $0.30/order (rate may improve with volume) | 2.4%-2.9% negotiated |
| Hosting and maintenance | $0-$100/mo | $100-$300/mo | $300-$1,500/mo |
| Content and SEO | Your time | $250-$500/mo | $500-$3,000+/mo |
| Year 1 total (before processing) | $500-$3,000 | $6,000-$20,000 | $20,000-$100,000+ |
A few things stand out in that table. First, the build is a one-time cost, but everything else recurs. Second, the "Growing" column is where most small businesses actually live, and it's where getting the foundation right pays off most: fixing a broken site architecture with 300 products is far more expensive than building it correctly the first time. Third, established stores spend more on content, SEO, and maintenance than on the platform, which is the opposite of what most people expect.
Hosted Platform vs. Self-Hosted vs. Custom
The platform decision drives more of your long-term cost than the initial build, so it's worth a closer look.
Hosted (Shopify, BigCommerce, Squarespace, Wix)
Best for: Owners who want to run the store themselves without thinking about servers, updates, or security.
Cost profile: Predictable monthly fee, low upfront cost, but you pay forever and the apps add up. You also accept the platform's SEO constraints (URL structures, limited control over code, page speed you can't fully tune).
Self-Hosted (WooCommerce and similar)
Best for: Businesses that want full control, own their data, and either have technical help or a maintenance plan.
Cost profile: Lower software cost, higher responsibility. Someone has to keep WordPress, the theme, and every plugin updated. Skip that and you'll eventually pay for it in downtime or a security cleanup.
Custom SEO-First Storefront
Best for: Stores where organic search is the primary growth channel, catalogs with complex structure, or businesses that have outgrown template limitations.
Cost profile: Higher build cost, lower ongoing platform fees, and the most control over the things that affect rankings: page speed, structured data, internal linking, faceted navigation, and clean URLs. This is the approach we take with our ecommerce web design work, and it's the right call for some businesses and overkill for others. If you're selling twenty products and your traffic comes from Instagram, a hosted platform is the better use of money.
Our guide to custom websites vs. templates goes deeper on when custom is worth the premium.
Where Store Owners Overspend and Underspend
After enough conversations about ecommerce budgets, the same patterns show up.
Overspending on the build, underspending on what happens after. A $15,000 store that nobody updates, that has no content strategy, and that never earns organic traffic will underperform a $4,000 store with $300 a month of consistent SEO and maintenance behind it. Organic rankings take months to build (see how long SEO takes), so plan for the ramp.
Ignoring processing fees in the pricing model. If your margins are 20% and processing takes 3%, that's 15% of your profit. Factor it into pricing from day one.
Buying apps instead of fixing the theme. Many stores stack $150 a month of apps to work around a template that was never right for the business. Sometimes a rebuild is cheaper over 24 months than the workarounds.
Skipping product photography and descriptions. Manufacturer photos and copied descriptions are the fastest way to a store that neither ranks nor converts. Budget real money or real time here.
Underspending on the checkout. Cart abandonment is one of the biggest revenue leaks in ecommerce. Guest checkout, visible shipping costs, and fast pages are cheap to get right and expensive to ignore.
How to Budget for Your Store
- Start with your revenue target. If you need the store to do $10,000 a month, a $200-a-month platform and app stack is fine. If you're testing an idea, keep the fixed costs near zero until it proves out.
- Count your products honestly. Under 50, hosted templates work well. 50-500, invest in structure and product page SEO. Over 500, plan for custom architecture and a real content budget.
- Model year one, not launch day. Add build cost plus 12 months of platform, apps, hosting, maintenance, and marketing. Then subtract expected processing fees from your margin.
- Decide who maintains it. Either you, a freelancer on retainer, or a plan from whoever built it. "Nobody" is not an option for a store that takes payments.
- Leave room for growth. The store you launch should not need to be rebuilt the moment you add 100 products or a second sales channel.
If you're still deciding between building a store and a simpler business site, our website design cost guide covers non-ecommerce pricing in the same detail.
Where Built For Rank Fits
We build custom, SEO-first storefronts starting from our $1,500 base build, with catalog size, payment integrations, and custom features quoted separately and up front. Ongoing hosting and maintenance run through the same monthly plans as our other sites: Host at $20 a month, Maintain at $99, and the Grow ($249) and Scale ($499) plans that add SEO blog posts and reporting. Change requests come in by text or voice memo, you own the site, content, and domain, and there's no long-term contract. That's a good fit for stores where organic search matters and the catalog has some complexity. If you're launching a small store on Shopify and your traffic will come from social or ads, we'll tell you that a hosted platform is probably the better spend. Either way, a free consultation will get you a straight answer on what your store should cost.
