Ecommerce Website Development Cost in 2026: $15K to $50K
What an ecommerce website costs in 2026: Shopify from $29 a month, a custom first version at $15K to $50K, portals $50K to $100K. Dated price table.
Mar 25, 2025
Short answer: a custom ecommerce website built by a senior team costs $15,000 to $50,000 for a launched first version: storefront, checkout, one payment route, your catalog migrated, one or two integrations, deployed on accounts you own. A store that is also a customer portal, with ERP or warehouse sync, B2B pricing, subscriptions or several fulfilment routes, runs $50,000 to $100,000. Keeping it shipping afterwards costs $5,000 to $10,000 per month without engineers of your own. Those are KUMO's published bands. Setting up Shopify yourself starts at $29 per month billed yearly; Shopify Plus starts at $2,300 per month on a three-year term. Platform prices below were read from Shopify's own pricing pages on 30 September 2026.

Ecommerce website cost in 2026, by route
| Route | What you get | Cost | Source, read 30 Sep 2026 |
|---|---|---|---|
| Shopify, set up by you | Hosted store, theme, checkout, apps from the store | Basic $29, Grow $79, Advanced $299 per month billed yearly ($39, $105, $399 monthly). Online card rates 2.9%, 2.7%, 2.5% plus 30 cents. 2%, 1%, 0.6% extra with a third-party payment provider | shopify.com/pricing |

| One US employee web developer | One developer, no design, no QA, no cover when they are away | Median web developer wage $92,650 per year before benefits and recruiting | US Bureau of Labor Statistics, Occupational Outlook Handbook, May 2025 wage |
| First production version, senior team (KUMO Starter Build) | Storefront and checkout on Shopify or custom, catalog migration, one or two integrations, analytics, your accounts, code yours from day one | $15,000 to $50,000, typically 2 to 3 months | KUMO published band |
| Commerce system or customer portal (KUMO) | ERP, warehouse or CRM sync, B2B pricing and approvals, subscriptions, multiple fulfilment routes, larger migration | $50,000 to $100,000 | KUMO published band |
| Ongoing engineering after launch (KUMO) | Monitoring, integration fixes, releases, performance, new workflows | $5,000 to $10,000 per month | KUMO published band |
One number from that table that most budgets miss: card fees usually cost more than the plan. On yearly billing, Grow's lower card rate pays for its higher fee once online card sales pass about $25,000 a month, and Advanced overtakes Grow at about $110,000 a month. That is arithmetic on Shopify's published rates, before any feature difference.
What moves the number
1. Where product, stock and order data live. A store that owns its own catalog is simple. One that takes stock from an ERP, a warehouse or a supplier feed needs rules for which system wins, retries when a sync fails, and someone who sees the exceptions. This is the single largest jump inside the band.
2. Checkout rules. One product type, one currency and card payments come with the platform. Subscriptions, bundles, configurable products, B2B price lists, purchase approvals and multiple currencies each add build and test work.
3. Whether the store is a portal. Quote requests, negotiated pricing, reorders, invoices, returns and account-manager access turn a storefront into a business application with roles and status histories. When buyers search for "ecommerce portal development", this is usually what they mean.
4. Migration. Moving from WooCommerce, Magento or an older build means products, customers, order history, reviews and every old URL redirected. Skipping redirects costs organic traffic that took years to earn.
5. Integrations after the first two. CRM, email and WhatsApp, support, tax, shipping and analytics are each a data contract: which events move, how often, and what happens when one side is down.
6. Design and speed. A theme with your brand is weeks less work than a designed storefront. Either way, page speed and checkout reliability during a campaign are what the revenue depends on.
Three quotes for the same brief
The brief: a D2C brand with about 300 products, subscriptions, stock synced from a warehouse system, moving from WooCommerce.
- $8,000 to $15,000: a customised Shopify theme, subscriptions and warehouse sync through apps, migration of products only. Fine if that is the job; ask who owns the app accounts, what the apps cost each month, and what happens to old URLs and customer logins.
- $35,000 to $50,000: the brief as written: designed storefront, subscriptions, a warehouse integration with retries and an exceptions view, full migration with redirects, analytics, handover documentation. Where most first versions land.
- $120,000 and up: a headless custom platform with every future idea included. Sometimes right; usually better as two phases with real orders in between.
The test is which quote says, in writing, what is in and out, which system owns stock and orders, who owns the code and the accounts, the monthly app and platform fees, and the price of a change. How to compare software proposals has the checklist.
What the Starter band buys at KUMO
A KUMO Starter Build ($15,000 to $50,000) for ecommerce is a launched store, not a mockup: storefront and checkout on Shopify or a custom stack, one payment route with defined order states, your catalog migrated with redirects, one or two integrations with failure handling, analytics, and a handover another engineer can continue from. Two to three months is typical. The code, the store and the accounts are yours from day one.
How the Shopify side works is on Shopify custom development; fully custom commerce and portals are on custom software development. For a B2B example of ordering, invoicing and deposit ledgers in one system, see the Equipp case study. If you are deciding whether Shopify still fits, when Shopify is not enough for a D2C brand covers that decision, and the Shopify website development cost guide prices the platform route alone.
Costs after launch
Budget from month one for the plan fee, apps (most stores run several paid apps), card fees, a domain, and any theme licence. Then engineering time: integrations break when the other side changes its API, campaigns need landing pages and discount logic, and the warehouse or ERP will ask for new fields. Without engineers of your own that is the $5,000 to $10,000 per month band, or a smaller retainer once the store is stable. Software maintenance cost in year one breaks it down.
How to get a real number this week
- Write one page: what customers buy, the checkout rules, which system owns products, stock and orders, the integrations, what moves from the old store, and what is out of version one. That page is your ecommerce website scope of work.
- Run it through the cost calculator to see the band.
- Send the same page to two or three teams and ask for scope in and out, ownership of code and accounts, monthly platform and app fees, timeline with milestones, and the price of a change.
- Prefer the quote that answers all five in writing.
If you would rather scope that page with an engineer, book a free 30-minute call and bring whatever you have.
FAQ
How much does an ecommerce website cost to develop? $15,000 to $50,000 for a launched custom first version with a senior team; $50,000 to $100,000 when it is a portal or syncs with ERP, warehouse or CRM systems; $5,000 to $10,000 per month to keep shipping afterwards. Setting up Shopify yourself starts at $29 per month billed yearly, plus card fees, read 30 September 2026.
What does a custom ecommerce website cost compared with Shopify? Shopify moves checkout, hosting and security onto a monthly fee, so the build is smaller. Custom costs more up front and fits when stock, pricing or approval rules do not match the platform. Many builds are Shopify plus custom integrations, which sits inside the Starter band.
How much does an ecommerce website cost in the UK? KUMO's bands are the same for UK buyers and are quoted in US dollars. Shopify publishes local prices by country; the figures on this page are from its US pricing page.
How long does an ecommerce website take to build? A Starter Build typically takes two to three months from scoped brief to launch. A portal with ERP sync or a large migration takes longer, and the quote should carry milestones.
What should an ecommerce website scope of work include? Products and checkout rules, the system that owns stock and orders, each integration and its failure path, migration and redirects, acceptance criteria for checkout and payments, and who runs the store after launch.
Where to get a turnkey ecommerce integration project with scope, timeline, and cost estimates? Ask two or three teams to quote the same one-page brief, and require scope in and out, milestones, ownership and the price of a change in writing. KUMO does this on a free 30-minute call.
What is the cost of maintaining an ecommerce website? Platform and app fees, card fees, hosting if custom, and engineering time for integrations and releases: $5,000 to $10,000 per month without your own engineers, less once the store is stable.
