COST GUIDE

How Much Does eCommerce Website Development Cost?

An online store can be a themed shop on a hosted platform or a fully custom marketplace. This guide shows what each typically costs, what drives the price, and how to choose the option that fits your products and plans.

Estimate your online store

Typical range: $3k to $100k+
Typical timeline: 3 weeks to 9 months
Platform options: Hosted, open source or custom

Typical cost by store type

Stores differ mostly in how much is custom. These three bands cover the requests we see most often.

Starter online store

An established platform with a themed design, payment and shipping setup, and product import.

$3k – $10k 3 to 8 weeks

Custom storefront

Custom design, tailored checkout, integrations with inventory and accounting, and performance tuning.

$10k – $40k 2 to 5 months

Marketplace or multi-vendor

Multiple sellers, commissions, vendor dashboards, and complex catalogue and order logic.

$40k – $100k+ 5 to 9+ months

These are indicative ranges for projects built by a small, senior team. They are a planning guide, not a quote. A real estimate depends on your scope, integrations, and how much of the design is already decided.

Platform options compared

Where the store is built affects both the upfront cost and what you pay every month afterwards.

Approach	Best for	Cost profile	Trade-off
Hosted platform	Fast launch with standard needs	Lower build cost, monthly subscription and fees	Less control over checkout and custom logic
Open source store	Content led shops and moderate customisation	Moderate build cost, hosting and extensions	Plugins need regular updates and review
Custom build	Unusual workflows, B2B selling and marketplaces	Higher build cost, no platform fees	You own upkeep and hosting

What drives the cost

Six decisions account for most of the difference between a small store and a large one.

Platform choice

Hosted, open source or custom. This is the largest single factor in both build and running cost.

Catalogue size and variants

Hundreds of products with sizes, colours and bundles take more setup than a dozen simple items.

Payments, shipping and tax

Local payment methods, delivery rules and tax handling differ by country and add configuration and testing.

Design and conversion

A clean, conventional store is faster to build than a fully custom design with unique page layouts.

Integrations

Inventory, accounting, CRM and marketing tools each need connecting and maintaining.

Speed and search visibility

Fast pages and clean structure cost effort up front and bring traffic and sales for years.

Ways to keep store costs down

Smart choices early save money for the life of the store.

Start on an established platform unless your workflow truly needs custom logic.
Launch with your best selling products and add the rest later.
Use standard payment and shipping providers instead of building your own.
Prepare product photos and descriptions before development starts.
Choose a simple, proven design and invest in speed and clarity.
Plan the monthly running costs alongside the build cost.

The costs after launch

The build is only part of what an online store costs. Payment providers take a percentage of each sale, hosted platforms charge monthly fees, and stores need regular updates, backups and security checks. Marketing also usually costs more than most founders expect, because a store with no visitors makes no sales.

Put these into the plan from the beginning. A store with a realistic budget for running and promoting it will almost always outperform a beautiful one that ran out of money at launch.

THE FIRST STEP

Let's define the right next move.

Share your goals, your current setup, and the main challenge you want to solve. We will use that context to discuss a practical scope and the information needed to plan the work.

Start a project conversation

Choose the platform before you price the store

The biggest cost decision in an online store is the platform. A hosted service launches quickly with monthly fees, an open source store gives more control, and a custom build suits unusual workflows. We help you compare them against your catalogue, your checkout needs and your growth plans, then estimate the store that fits, not the most expensive one.

Frequently Asked Questions

How much does an eCommerce website cost?

A starter store on an established platform commonly costs $3,000 to $10,000, a custom storefront with tailored checkout and integrations often falls between $10,000 and $40,000, and marketplaces with multiple vendors can reach $40,000 to $100,000 or more.

Is it cheaper to use a hosted platform or build custom?

A hosted platform is usually cheaper to launch but adds monthly fees and limits on customisation. A custom build costs more upfront and has no platform fees, which can pay off for stores with unusual workflows or high volume.

What other costs should I plan for besides the build?

Payment processing fees, hosting or platform subscriptions, product photography, marketing, and ongoing maintenance. A common guideline is to set aside 15 to 20 percent of the build cost each year for upkeep.

Can you migrate my existing store?

Yes. We can move products, customers and order history to a new platform, test the result on a copy, and redirect old addresses so search rankings are protected.
