How much does it cost to build a marketplace?

It's a ladder, not a single price. A clickable prototype of the catalog, product page and seller dashboard is free and takes 5 days, before any contract. A marketplace MVP with catalog, search, buyer and seller dashboards, orders and split payments starts at $14,900 and takes 3–4 months: enough to run your first real deals and test demand. A launch with seller onboarding, moderation and analytics starts at $22,900. A full platform with a mobile app, chat and dispute resolution runs $60–150K, built in stages and by then funded by your commission revenue. We fix the price for the agreed scope, and the code and infrastructure stay yours. To estimate a budget for your feature set, try the marketplace cost calculator.

Another agency quoted us many times more. Why do you start at $14,900?

They're pricing different things. A big quote usually covers "the whole marketplace": every role, a mobile app, chat, dispute resolution, analytics, fraud prevention. We start with the core of the deal: catalog, seller dashboard, ordering, split payments and escrow, from $14,900 in 3–4 months. That's enough to get your first real transactions and find out which of the other features you actually need. After that the platform grows in stages on the marketplace's own turnover, $60–150K in total, but not in one payment and not before your first revenue.

How does a marketplace make money, and when does it pay off?

Four models work: a commission on every deal (5–15%, the default for goods and services), a seller subscription for listings, pay-per-lead or per request, and paid promotion in the catalog. We choose the model with you during discovery and run the unit economics: at what commission and how many deals a month the marketplace breaks even. A rule of thumb: at a 10% commission, an MVP at $14,900 pays for itself once the marketplace has moved roughly $150K in sales. That's why we start with one category, where turnover shows up fastest.

How do we handle sellers legally: receipts, payouts, taxes?

The standard setup is an agent model: you accept the buyer's money on the seller's behalf, keep your commission and pay out the rest. Payment platforms cover the technical side: Stripe Connect, PayPal or your bank's gateway can split payments, verify sellers and pay out to individuals and companies. In the MVP we include the seller agreement, a payout ledger and an export for your accountant. The exact setup is agreed with your lawyer during discovery.

How do you solve the chicken-and-egg problem at launch?

Three proven strategies: 1) start with one side by aggregating sellers' catalogs before they even sign up; 2) start as one large seller's storefront, then open up to others; 3) subsidize one side (no commission for the first 3 months). We help you pick a strategy during discovery.

Can we start as a regular online store and become a marketplace later?

Yes, and it's a common strategy. We build a multi-vendor architecture from day one, even if at launch you only sell your own products. Adding sellers later is a matter of configuration, not rewriting code.

How do you keep content quality up with thousands of sellers?

Three levels: automatic rules (minimum photos, description, category), AI moderation (duplicates, prohibited content), and manual review for borderline cases. With 10K+ listings, manual moderation takes less than an hour a day.

When it matters

Situations where we help

If you recognize even one, we can be useful

An off-the-shelf platform forces you into someone else's business model

Ready-made engines (CS-Cart, Sharetribe and the like) don't know your rules: provider ratings, escrow, slot booking, custom B2B pricing. Customizing the box quickly costs more than building your own, and the UX still looks like a template.

The marketplace is empty: no sellers, no buyers

The classic chicken-and-egg problem: without a cold-start strategy the marketplace sits empty and the development budget burns. You have to launch from one side: aggregate catalogs, open as an anchor seller's storefront, subsidize early participants.

How to split money with sellers safely

Split payments, escrow, refunds, commissions, receipts for other people's sales, tax reporting: every piece is harder than it looks. Without a reliable payment flow you get fraud, disputes and churn.

The catalog grew and search ground to a halt

An off-the-shelf engine can't keep up as the catalog grows: search slows down, pages take 10 seconds to load, buyers leave for competitors and sellers follow the buyers. At tens of thousands of visitors, that's thousands of lost orders.

Features and benefits

Concrete results we deliver for you

Goods, services, rentals, B2B, C2C

No template limits. A product marketplace with delivery, a services marketplace with slot booking, rentals with monthly billing, a B2B platform with tenders: we design it around your economics.

Split payments and escrow built in

Stripe Connect, PayPal or your bank's gateway: the buyer pays → the money sits in escrow → the seller gets paid minus your commission. Automatic payout splits, refunds, KYC for sellers.

Search across a catalog of 500,000+ items

Elasticsearch for full-text search and faceted filters, a CDN, lazy loading. In the SHATE-M project, a catalog of 500,000+ items with search by VIN and cross-reference numbers responds in milliseconds.

Seller, buyer and admin dashboards

Seller: catalog, orders, payouts, rating, sales analytics. Buyer: order history, favorites, reviews, returns. Admin: moderation, stats, commission management.

Seller price lists sync on their own: ERP, product feeds, Excel

Sellers don't have to enter their catalog by hand: we connect their accounting or ERP system (QuickBooks, Xero, NetSuite, SAP Business One) via API, import XML and CSV product feeds and Excel price lists, and keep stock and prices in sync. The lower the barrier for sellers, the faster the marketplace fills up.

Content moderation and fraud prevention

Automatic listing checks (AI plus rules), a complaints and dispute system, blocking of fraudsters. Manual work stays minimal, so moderation doesn't become a growth bottleneck.

Process

Full design for buyers, sellers and admins, based on the approved prototype. Mobile-first, with the key flows tested: search → choose → order → pay → review.

Stage 4

MVP development: 6–8 weeks

Catalog, search, product and service pages, ordering, user dashboards, moderation. A demo every 2 weeks, so you stay in control of progress.

Stage 5

Payments and security: 2–3 weeks

Split payments, escrow, seller KYC, fraud prevention, refunds. Everything tested and ready for real transactions.

Stage 6

Marketplace development: first deals first, scale later

A marketplace isn't a storefront, it's a deal engine: catalog, seller dashboards, split payments, escrow and dispute resolution. We break a turnkey marketplace build into steps. A clickable prototype of the catalog, product page and seller dashboard is free and takes 5 days, before any contract. A marketplace MVP starts at $14,900 and takes 3–4 months, enough for the first real deals. A full platform with a mobile app, chat and dispute resolution runs $60–150K, built in stages and by then funded by commission revenue. We start with one category and one city, which makes it easier to gather the first sellers and buyers. A step-by-step launch plan is in our article on launching a marketplace.

Our projects show this kind of platform holds up under load. The SHATE-M B2B portal runs a catalog of 500,000+ items on top of 1C (a popular ERP and accounting platform in Eastern Europe), with dealer accounts and personal pricing: a year later, dealers were placing 70% of orders themselves and sales had grown 35%. A payment flow with escrow and verification was proven in our fintech MVP case: Stripe and PCI DSS, 10,000+ transactions in the first month of beta without a single failure. How far a two-sided customer ↔ contractor model can scale is shown by the ERP/FSM platform in the US: the client's revenue tripled in 18 months.

Before you start, it pays to compare paths: an off-the-shelf platform tends to run into fees, template design and growth limits. The marketplace cost calculator estimates a budget for your feature set, the architecture is covered in our guide to building a marketplace from scratch, and a detailed module-by-module estimate is in the article on marketplace development cost.

We also build for specific niches: a services marketplace with slot booking, an auto parts marketplace with VIN lookup, a real estate platform. If you have a single seller and sell only your own products, that's not a marketplace yet but a web app or B2B portal from $4,900. If you need to test a hypothesis quickly without a payment flow, start with an MVP core from $9,900. A subscription service is closer to SaaS development. Price ranges for every service are on our development pricing page.

ERP modernization and a B2B portal for an auto parts distributor

Auto parts and distribution

Experience from our CTO's portfolio: ERP modernization and the launch of a B2B portal for a large auto parts distributor with a catalog of 500,000+ items. 1C (a popular ERP and accounting platform in Eastern Europe) connected via REST API, search by VIN and cross-reference numbers through TecDoc, dealer accounts with personal pricing. The project was completed before March Code was founded.

«Dealers stopped calling managers to ask whether something is in stock: they see the stock in the portal themselves. An order takes minutes and goes into 1C without anyone retyping it. Within a year, 70% of our total turnover went through the portal, and that changed how our sales department works.»
