What E-commerce Development involves
An online store lives or dies on speed and trust. A slow, clunky checkout on mobile is money walking out the door. I build storefronts that are fast, mobile-first, and easy to buy from, whether fully custom or a headless Shopify front end on your existing backend.
I handle the parts that actually break: secure payment flows, subscription billing, inventory sync, and the failure states most builds ignore. Every checkout path is tested before it meets a real card.
What you actually get
Speed that sells
A fast store keeps more of the visitors you paid to acquire.
Payments done right
Secure, tested checkout with Stripe, Paddle, or Shopify.
Mobile-first, always
Built and tested on phones first, where most shoppers are.
Estimate your e-commerce development cost
Answer three questions and pick any extras. You get a price range and timeline instantly, and can send it straight to me for a fixed quote.
Your estimate
About 4 to 5 weeks
A ballpark to plan with, not a quote. Your answers go along with the brief, so the fixed quote comes back faster.
Or skip the quote
Build it on the Build plan at $2,490/month instead. This estimate equals about 2 months of a plan, and the plan keeps going after launch. Pause anytime.

E-commerce Development cost breakdown
What e-commerce development typically costs at three levels of scope. Every project still gets its own fixed quote.

| Typical | $11,500 to $14,500 | 8 to 10 weeks |
|
| Advanced | $21,500 to $27,000 | 14 to 18 weeks |

What drives the cost
The platform
Shopify gets you selling fastest. Headless and custom builds trade setup time for full control over design and speed.
- Shopify theme, customisedBase

- Fully custom store+$7,000
Catalogue size
Large catalogues need import pipelines, fast search and filtering, and performance work to stay quick.

- 50 to 1,000 products+$1,500
- 1,000+ products or complex variants+$3,500
How you sell
A standard checkout works out of the box. Subscriptions, bundles, and multiple currencies need extra configuration and testing.

How much does e-commerce development cost?
E-commerce Development starts at $4,000. A typical mid-sized project runs between $11,500 and $14,500, and an advanced build between $21,500 and $27,000. You always get a fixed quote before work starts, and the cost estimator on this page gives you a ballpark in under a minute.
How long does e-commerce development take?
A starter project takes about 4 to 5 weeks, a typical one 8 to 10 weeks, and an advanced one 14 to 18 weeks. You see a live URL from the first week, so progress is visible the whole way.
What affects the cost of e-commerce development?
Three things move the price most: the platform, catalogue size, and how you sell. Optional extras such as product and customer data migration or reviews and loyalty integration add to the total.
Custom build or Shopify?
Whichever fits. Headless Shopify keeps its backend with a faster front end; fully custom gives control Shopify cannot.
Can you add subscriptions?
Yes. I have shipped subscription and one-time billing with Paddle and Stripe, including the webhook edge cases.
Is the checkout secure?
Payments run through PCI-compliant providers. I never handle raw card data, and every path is tested.
Need just one piece of this?
These fixed-price services have a set scope and delivery time. Order in two minutes, no quote needed.
