Websites built for marketplaces.

A marketplace is less a website than an economy with a storefront on top. Sellers need onboarding, listings, payouts, and a dashboard worth opening; buyers need search that works, a cart that handles several vendors in one payment, and enough visible trust to pay a stranger. The build serves both sides, and neither should feel the weight of the other. GEO Marketing Group designs and builds these sites for marketplaces across the United States, working remotely from Providence, Rhode Island, and this page links to a dedicated page for every state and major metro.

Quick answer

GEO Marketing Group designs and builds custom websites for marketplaces across the United States, working remotely from Providence, Rhode Island. Each marketplace site is built mobile-first around the way marketplaces win customers, quoted as a fixed price before work starts, and handed over so you own it outright. Choose your state below for local detail.

What gets in the way

The website problems marketplaces run into.

Sellers who list once and never come back

A clunky onboarding form and a dashboard that buries orders leave vendors with half-finished shops, and thin inventory is the first thing a buyer notices.

Checkout that splinters across vendors

When items from three sellers turn into three separate payments, three shipping estimates, and three confirmation emails, the cart is abandoned before the last one loads.

Trust that has to be earned twice

A buyer is trusting the platform and a stranger at the same time, and without visible seller profiles, reviews, and a plain-language dispute policy, neither side feels safe enough to transact.

Must-haves

What a marketplace website needs.

  • Seller onboarding with identity checks, payout setup, and a first listing in one guided flow
  • Split payments through Stripe Connect so a single checkout pays several vendors and collects your commission
  • Faceted search and category pages that stay fast at tens of thousands of listings
  • Vendor storefront pages with reviews, policies, and response times
  • Order, messaging, and dispute tools for both sides, with an admin view over all of it
  • Structured product data and clean URLs so listings are eligible for search and shopping results

FAQ

Marketplace websites: common questions.

How do payments and commissions work in a multi-vendor marketplace?

We typically use Stripe Connect. The buyer pays once, Stripe splits the payment between each seller and the platform, and your commission is taken automatically. Sellers onboard with their own payout details, so the platform is never the one storing their banking information.

Should we build custom or start on a platform like Sharetribe?

Start on a platform if you are still finding out whether buyers and sellers will show up; Sharetribe and similar tools get a working marketplace live quickly. Build custom once the model is proven and the platform's fees, design limits, or workflow rules start costing you. We do both and will tell you which fits.

How do you keep search fast with thousands of listings?

Listings are indexed in a dedicated search service such as Algolia, or in a tuned Postgres full-text index, with filter counts computed ahead of time rather than on every request. Category and vendor pages are pre-rendered wherever they can be so browsing stays quick under load.
