Adding a hosted payment link or buy button to an existing website may require 8-30 hours, roughly $400-$1,500 at Vertinus's $49.99 hourly rate. Adding a small catalog, cart, checkout, shipping, tax, and order workflow through an established commerce platform may take 60-200 hours, about $3,000-$10,000. A custom storefront or deep operational integration may require 200-600 hours or more, about $10,000-$30,000.

The website is only one part of ecommerce. Products, prices, tax, inventory, payment, fulfillment, shipping, refunds, customer service, privacy, security, and accounting must agree after the order is placed.

Planning range: $400-$1,500 for hosted checkout; $3,000-$10,000 for a small platform-based store; $10,000-$30,000+ for a custom or deeply integrated storefront. Platform plans, payment fees, tax and shipping services, licenses, product content, migration, support, and maintenance are separate.

Hosted checkout or buy button: 8-30 hours

This can fit a small number of fixed products, services, deposits, tickets, or donations handled by an established payment or commerce provider.

The work may include product and price setup, website presentation, checkout link or embed, success and cancellation behavior, receipts, analytics, mobile testing, and basic reconciliation guidance.

Small platform-based store: 60-200 hours

Approximately $3,000-$10,000 at $49.99 per hour.

A first release may include:

  • Catalog structure, products, variants, images, and prices.
  • Category and product pages.
  • Cart and hosted or platform checkout.
  • Payment, shipping, pickup, and approved tax setup.
  • Order confirmations and basic customer communication.
  • Returns, refunds, cancellation, and support information.
  • Analytics, metadata, sitemap, and structured product data.
  • Responsive, accessibility, performance, and checkout testing.
  • Administrator training and launch.

Custom or integrated ecommerce: 200-600 hours or more

Approximately $10,000-$30,000+ at $49.99 per hour.

Cost grows with customer-specific pricing, product configuration, inventory synchronization, subscriptions, memberships, bundles, several fulfillment locations, complex shipping, marketplace feeds, ERP or accounting integration, customer portals, approval, quoting, and large migration histories.

A complete custom commerce platform can require substantially more. The guide on how much an ecommerce website costs covers full-site ranges.

Can the existing website support ecommerce?

Assess the platform, hosting, source access, performance, security, navigation, content model, analytics, and maintenance process. Adding commerce to an unsupported or fragile site may cost more than moving the public site and store to a suitable foundation.

Keep the current marketing site when it performs well and a hosted checkout can integrate cleanly. Migrate when platform limits, security, content duplication, or operational fragmentation make the combined system hard to maintain.

What changes the estimate

Catalog and product data

Ten simple products are different from thousands of variants, options, bundles, compatibility rules, customizations, digital files, or regulated attributes.

Shipping and fulfillment

One flat rate is simpler than zones, weights, dimensions, carriers, multiple warehouses, local delivery, pickup, backorders, split shipments, and returns.

Tax and payments

Use established qualified providers and approved tax guidance. Multiple countries, currencies, exemptions, subscriptions, deposits, refunds, disputes, or marketplace obligations add work and recurring cost.

Inventory and accounting

Manual order export is narrower than real-time stock, purchasing, fulfillment, payment settlement, refunds, fees, taxes, and accounting reconciliation.

Migration

Products alone are simpler than customers, orders, reviews, subscriptions, gift cards, credits, redirects, metadata, media, and legally required historical records.

Example: add a 30-product store

A service business has an existing custom marketing site and wants to sell 30 standard products through an established hosted commerce platform. It needs product pages, cart and checkout, domestic shipping, tax-provider configuration, order email, analytics, and accounting export.

  • Platform, catalog, and operating setup: 16-30 hours.
  • Website and storefront integration: 24-50 hours.
  • Product entry and image preparation: 20-45 hours.
  • Shipping, tax, payment, and accounting setup: 18-40 hours.
  • Testing, analytics, training, and launch: 20-40 hours.

Total planning range: 98-205 hours, about $4,900-$10,250 at $49.99 per hour, plus platform, provider, and transaction fees.

How to reduce ecommerce cost

  • Start with the products customers already request.
  • Use an established commerce and payment platform.
  • Simplify variants, shipping, discounts, and fulfillment.
  • Prepare accurate product data and original images.
  • Keep rare or custom orders in a quote workflow.
  • Use one source of truth for products, orders, inventory, and accounting.
  • Pilot reconciliation before promoting the store broadly.
