Ecommerce website development cost: how budgets map to store types

Ecommerce stores fall into broad categories. Below are realistic cost ranges in 2025 and what each budget typically buys you.

Basic / Starter Store

$0 - $2,500

Good for testing products or low SKU counts

Shopify Lite or basic plan / WooCommerce on shared hosting
Simple catalog, standard checkout
Template design, minimal customisation

Growth Store

$2,500 - $12,000

For stores scaling traffic & conversion focus

Shopify/BigCommerce Pro or self-hosted WooCommerce
Custom design templates, improved UX, payment gateways
Essential integrations: shipping, tax, inventory

Custom / Enterprise

$12,000+

Large catalogs, multi-store or bespoke features

Custom platforms, headless commerce, or heavy WooCommerce customisation
Complex integrations (ERP, PIM, OMS)
Performance, security & compliance work

What drives the price?

Platform choice — Shopify, BigCommerce, WooCommerce, Magento, headless solutions
Number of SKUs — large catalogs need indexing, filtering, and performance optimisation
Custom features — subscriptions, memberships, multi-currency, custom checkout flows
Integrations — accounting, shipping, CRM, inventory

Design & UX — custom templates, animations, mobile-first layouts
Compliance & security — PCI-DSS considerations, privacy, data handling
Ongoing support — SLA, updates, performance monitoring
SEO & marketing setup — product schema, structured data, migrations

Monthly running costs to budget for

Beyond development, predictable monthly spending keeps your store healthy. Typical items:

Platform & hosting

$29 - $499+

Basic Shopify or shared hosting at the low end; dedicated servers, enterprise platforms at the high end.

Payment & transaction fees

1% - 3.9% + fixed fee

Gateway fees, chargeback insurance, multi-currency costs.

Apps & extensions

$0 - $300+

Add-ons for reviews, subscriptions, advanced shipping, analytics.

Maintenance & updates

$0 - $500+

If you have a monthly support retainer or pay per-hour for changes.

Marketing & advertising

$300 - $10,000+

PPC, social ads, remarketing — scales with growth goals.

Security & backups

$10 - $200

CDN, firewall, backup storage and monitoring.

Benchmarked monthly baseline for a small ecommerce shop: $150–$800 (platform, payment fees, a few paid apps, and modest marketing). Growth shops should budget 10–25% of projected revenue for marketing initially.

How to set a realistic ecommerce budget — 6 steps

Define launch goals

Decide whether the site is for validation (MVP), steady revenue or enterprise-level growth. Goals drive scope and cost.

List must-have features

Cart, checkout, product filters, shipping rules, subscriptions, multi-currency, third-party integrations. Prioritise essentials vs nice-to-have.

Choose platform & estimate baseline

Get quotes for Shopify, BigCommerce, WooCommerce (self-hosted) or headless options. Include hosting, SSL, and payment fee estimates.

Add marketing & SEO budgets

Plan an initial marketing budget (ads, content, email). Reserve budget for SEO improvements in months 1–6 to build organic traffic.

Estimate maintenance & contingency

Include monthly maintenance, app fees, and a 10–20% contingency for unexpected costs during launch.

Compare total cost vs expected revenue

Build a simple ROI forecast: expected monthly orders × average order value − monthly costs. Adjust budgets to meet ROI targets.

Quick template: For a small store expect Year 1 total = (development cost) + 12 × (monthly running cost + marketing). Use this to compare options.

Optimise SEO & marketing to reduce cost per order

Smart SEO and marketing decisions reduce your reliance on paid ads and increase long-term profitability. Focus on high-return activities first.

Technical SEO (one-time)

Site speed: optimise images, lazy-load, use a CDN. Faster sites convert and rank better.
Mobile-first: ensure mobile UX is flawless — Google indexes mobile-first.
Structured data: product schema, price, availability and reviews for rich results.
Sitemap & robots: submit sitemap, set canonical URLs and avoid indexation issues.

Marketing & growth (monthly focus)

Paid ads: start small, measure CAC (customer acquisition cost) and ROAS; scale winners.
Email flows: welcome series, abandoned carts and post-purchase upsells convert well at low cost.
Content & category pages: rank for long-tail product searches to attract free traffic.
Reviews & UGC: social proof increases conversion rate; incentivise honest reviews.

Practical prioritisation: If budget is limited, sequence work as:

Fix site speed & mobile issues (biggest immediate lift).
Implement product schema and critical SEO tags.
Set up analytics & conversion tracking (measure everything).
Create high-converting email flows (low CAC).
Run small ad tests and scale top performers.

Practical ways to reduce development & running costs

Use proven templates & blocks

Start with a high-quality ecommerce theme and customise only what improves conversion. Saves time and development hours.

Limit third-party apps

Every app adds maintenance and monthly fees. Combine functionality where possible and remove redundancies.

Phase the project

Launch an MVP with core features. Add advanced functionality in later phases funded by early revenue.

Use managed services

A subscription-based managed ecommerce provider can bundle hosting, updates and small changes into one predictable fee — often cheaper than paying hourly.

Pro tip: Track dev hours on a small pilot. If outsourcing, ask for a fixed-scope quote for Phase 1 and hourly rates for later changes to avoid surprise bills.

How to choose the right development partner

1. Transparent pricing

Look for clear quotes that separate one-time build costs from monthly fees and ongoing support.

2. Delivery speed & process

Ask for a timeline with milestones and what you must supply (product data, images, shipping rules).

3. Support & updates

Check if small changes are included, response SLAs and whether they offer predictable monthly plans.

If you prefer a managed subscription model, providers like Congero offer fast launches, built-for-mobile design, unlimited updates via simple messages, and bundled hosting & domain for a flat monthly fee — useful for busy store owners who prioritise predictable costs and fast time-to-market.

Typical project timeline & milestones

MVP / Starter Store — 1–3 weeks

Requirements & content: 1–3 days
Theme setup & product import: 3–7 days
Checkout testing & launch: 2–3 days

Growth store — 3–8 weeks

Custom UI/UX and conversion optimisations
Integration with shipping, tax and CRM systems
Staged testing and UAT before launch

Custom / Enterprise — 8+ weeks

Complex integrations, performance engineering and security audits
Multiple stakeholders, staging and load testing

Launch checklist: analytics & goals, payment & shipping live, tax rules applied, product QA, responsive checks, SEO meta tags set, and customer testing (place a test order).

Frequently asked questions

How much does a simple Shopify store cost to build?

A simple Shopify store using an off-the-shelf theme with up to 50 products can be launched for $500–$3,000 depending on customisations and product data work.

What ongoing marketing budget should I plan for?

Many small stores start with $500–$2,000/month for ads and email marketing. Reinvest a portion of revenue; as CAC improves, scale ad spend.

Can I reduce dev cost by doing product import myself?

Yes — providing clean CSVs and images reduces development hours. If you have time, hand off well-structured data to your developer to save money.

Is it better to rent a managed service or pay a custom build?

If you value predictable monthly costs, fast launches and unlimited small updates, a managed subscription works well. Custom builds make sense when you need unique, high-scale functionality and full ownership of the codebase.

Ready to plan your ecommerce budget?

Use the steps above to create a realistic cost plan. If you want a fast, all-in-one option that bundles hosting, updates, domain and SEO into a single monthly fee, consider a managed ecommerce subscription.
