How much does it cost to build a marketplace website?

“How much will my marketplace cost?” is the first question almost every founder asks me, and “it depends” is the least useful answer anyone can give. So here is how I actually price a marketplace: module by module, with the decisions that move the number up or down.

The short answer

For the marketplaces I build with custom code, a working first version usually comes to $200–$1,200 and takes 1–6 weeks. That covers a platform people can sign up to, list on, order from and pay through, with an admin panel to run it.

Agency quotes for the same scope are often several times higher. Part of that is overhead: project managers, account teams and separate designers all sit inside the price. Part of it is scope: many first quotes include features a marketplace does not need on day one.

What you are actually paying for

A marketplace is a set of modules that work together. These are the ones almost every build needs:

• Accounts and profiles for buyers and sellers, often with a verification step before sellers can trade.
• Listings and search: services or products by category and location, with filters people actually use.
• Orders, from a simple purchase to milestones for bigger jobs.
• Payments: taking money, keeping your commission and paying sellers, sometimes with escrow in between.
• Messaging, so questions and delivery stay on your platform.
• Reviews and disputes, which build trust and give you a fair way to settle problems.
• An admin panel to approve sellers, handle disputes, manage payouts and see what is happening.
• Emails and notifications for every step, so nobody misses an order.

Each module is a piece of the budget. The estimate on this site lets you switch modules on and off and watch the range change.

The decisions that move the price most

Escrow and payouts

Holding a buyer’s payment until the work is approved is one of the best trust builders a marketplace can have, but it adds states, rules and edge cases: releases, refunds, disputes and payout schedules. I explain the full flow in how escrow payments work on a service marketplace.

Languages and countries

A second language means every page, email and error message exists twice. Several countries can mean several currencies, tax rules and payment methods.

Search and matching

Browsing by category is simple. Matching buyers to the right seller by skills, availability and location is a feature of its own.

Phone apps

An installable web app gives you a home-screen icon at no extra cost. Native store apps are a separate project. I compare both in progressive web app or native app.

How to keep version one affordable

1. Launch around one core transaction. One kind of buyer hiring one kind of seller, done really well.
2. Keep some steps manual at first. A person checking seller documents is cheaper to build than automated verification, and it works on day one.
3. Use proven payment providers. Stripe and PayPal already handle cards, security and payouts, so you pay for integration rather than reinvention.
4. Add features when users ask for them. Real requests make a better roadmap than guesses.

A real example

Diatitis is an escrow marketplace where people abroad hire verified providers back home in Ghana, Cameroon and Côte d’Ivoire. Providers are verified by a person, services are organised by category and city, buyers can message before ordering, payments are released only on approval, disputes freeze payouts, and the whole platform runs in English and French. Every one of those decisions shaped the budget, and every one earns its place.
