E-Commerce & Marketplaces
Conversion-optimized storefronts and multi-vendor marketplaces engineered to sell across web, mobile, and POS.
Most e-commerce work falls into one of two buckets: get a store live fast on a proven platform, or build something a template can't do. We handle both. Straightforward catalogs go on Shopify, often via Hydrogen when you need a fully custom front end without giving up Shopify's checkout and admin. Once your pricing logic, vendor relationships, or catalog structure get complicated — tiered B2B pricing, multiple sellers, subscription billing — we move to headless: Medusa or Next.js Commerce, with PostgreSQL underneath so orders, inventory, and customer data stay consistent as the business grows.
Marketplaces are their own discipline. A two- or three-sided platform needs vendor onboarding, commission splits, and payouts that don't require your team to manually reconcile who's owed what — we build that on Stripe Connect. Algolia handles product discovery once a catalog is too large for basic filtering to work. The same underlying stack supports B2B portals — net terms, quoting, bulk ordering for trade accounts — and subscription commerce, where the hard part isn't the first charge but the churn-aware flows around failed payments, pauses, and plan changes.
This work is for teams outrunning a store builder, launching a marketplace from scratch, or migrating off a legacy cart without losing SEO rankings or order history in the process — a step we treat as a launch requirement, not an afterthought. Whether the goal is web, mobile, or in-store POS integration, the storefront and the backend are built to the same contract, so pricing, inventory, and orders stay in sync everywhere a customer can buy.
Our process
Platform & Architecture
We assess your catalog, vendor, and pricing complexity to choose Shopify or Shopify Hydrogen for a fast launch, or Medusa/Next.js Commerce for custom logic, backed by PostgreSQL.
Storefront & Payments Build
We build the storefront, checkout, and backend: Stripe or Stripe Connect payments, vendor dashboards and payout splits for marketplaces, and Algolia-powered search.
Business-Model Logic
We layer in what makes the model work: tiered B2B pricing and bulk ordering, churn-aware subscription billing, or vendor matching and commission splits for marketplaces.
Migration & Launch
For replatforming projects, we move products, customers, and order history off the legacy cart with SEO-preserving redirects, then launch across web, mobile, and POS.

E-Commerce & Marketplaces
E-commerce and marketplace development is the design and engineering of online stores and multi-vendor platforms that take orders, process payments, and keep inventory in sync across web, mobile, and point-of-sale. Prixelo builds both kinds of project: straightforward catalogs on Shopify or Shopify Hydrogen, and headless or custom builds on Medusa or Next.js Commerce with PostgreSQL when pricing, vendor, or catalog logic outgrows a template. It suits teams outrunning a store builder, founders launching a two- or three-sided marketplace, B2B sellers that need net terms and tiered pricing, and businesses moving off a legacy cart. Typical deliverables include the storefront and checkout, Stripe or Stripe Connect payments with vendor payouts, Algolia search, subscription billing, and a migration plan that keeps SEO rankings and order history. Shopify builds start from $6,000, custom headless stores from $20,000, and full marketplaces from $45,000+, with the final figure scoped to the actual catalog and business model.
Questions buyers ask
What does e-commerce development include?
E-commerce development covers everything needed to sell online: the storefront, product catalog, cart and checkout, payments, and the backend that manages orders, inventory, and customers. Depending on the business model it can also include vendor dashboards and payouts for marketplaces, recurring billing for subscriptions, quoting and net terms for B2B buyers, product search, and migrating products, customers, and order history from an existing platform.
What is headless commerce, and when is it worth it?
Headless commerce separates the customer-facing storefront from the commerce backend, so each can be built and changed independently. It is worth it when a standard theme cannot express your pricing rules, catalog structure, or content needs. If your catalog and checkout are conventional, a regular Shopify store is usually faster and cheaper; Shopify Hydrogen is a middle ground that keeps Shopify's checkout and admin behind a custom front end.
How do marketplace payments and vendor payouts work?
In a multi-vendor marketplace, the platform collects the customer's payment, keeps its commission, and pays each seller their share. We build this on Stripe Connect, which handles vendor onboarding, split payments, and payouts, so your team does not have to reconcile who is owed what by hand. Escrow-style holds can be added when funds should only be released after delivery or approval.
How do you migrate an online store without losing SEO?
A store migration keeps search rankings by preserving or redirecting every URL that already earns traffic. We map old product, category, and content URLs to their new equivalents, set up permanent redirects, carry over titles and metadata, and move products, customers, and order history before launch. Checking redirects and crawl errors after go-live is part of the launch work, not a follow-up task.
Can B2B wholesale and retail customers use the same store?
Yes, B2B and retail buyers can share one platform when the backend supports separate rules for each. Trade accounts can see tiered or customer-specific pricing, request quotes, place bulk orders, and pay on net terms, while retail shoppers get the normal checkout. Keeping both on one system means inventory and order data stay consistent instead of being split across two tools.
