Custom marketplace — your own platform for a monthly fee

A marketplace is the hardest discipline in online business: you have to convince two sides at once — vendors to list and customers to buy. Technology should be the least of your worries. Yet agencies charge millions for marketplace development, so most ideas die before they're ever validated.

We build marketplaces differently: we start with an MVP for a monthly fee from CZK 9,900, launched within three months. You validate demand in a narrow niche, and only when the model works do we expand — commission system, split payments, mobile apps. You pay as you go, not millions upfront.

Whether you're planning a marketplace for tradespeople, tutoring, equipment rental or B2B purchasing, the principles are the same: smooth vendor onboarding, trustworthy payments and reviews that build reputation. That's exactly what we build on.

Why most marketplace projects fail

A million-crown investment before validating demand

Traditional marketplace development costs 1–3 million CZK — before you even know whether anyone wants it. The subscription model flips the order: a lean MVP first, investment in expansion only based on real numbers.

The chicken-and-egg problem: vendors without customers, customers without supply

Nobody visits a marketplace without listings, and nobody lists without visitors. The solution is starting with a narrow niche and recruiting the first vendors by hand — the MVP must support that, not get in the way.

Off-the-shelf platforms can't handle your commission model

Template marketplace platforms have fixed commissions, payment flows and onboarding. The moment you need deposits, escrow, custom vendor approval or B2B price lists, you hit a wall.

Three-party payments are legally and technically complex

Money flows from the customer through you to the vendor — split payments, refunds, commissions, invoicing. A badly designed payment flow means manual accounting and risk. We design it right from the start.

What a custom marketplace can do

Vendor onboarding and management

Registration, verification, listing approval, vendor profiles and performance overview. You decide who sells on your platform.

Commission model and split payments

Automatic payment splitting between you and vendors (Stripe Connect and similar), per-category commissions, monthly statements and invoicing exports.

Catalogue and smart search

Categories, filters, full-text and geolocation search. Listings surface so customers find what they need — and every vendor gets a fair chance.

Reviews and trust building

Two-way ratings, moderated reviews, verified vendor badges. Trust is the currency of a marketplace — the system has to reinforce it.

Moderation and administration

Content approval, dispute resolution, account blocking, transaction overview and marketplace-wide statistics in one admin.

Mobile apps for both sides

Apps for customers and vendors with push notifications for orders, messages and reviews. Engagement and purchase frequency grow.

Frequently asked questions

How much does a custom marketplace cost?

An MVP marketplace starts at CZK 9,900 per month as a subscription, or from CZK 119,000 one-time. A full marketplace with split payments and reviews from CZK 19,900 per month, and a version with mobile apps from CZK 29,990 per month. Traditional agencies charge 1–3 million CZK upfront for a comparable scope.

How long does marketplace development take?

We launch a niche MVP in 2–3 months, a full marketplace with payments and reviews in 3–5 months, and a complete solution with mobile apps in 4–6 months. We recommend starting with an MVP and expanding based on real traction.

How are payments between customer, marketplace and vendor handled?

Through a payment gateway with split payment support (e.g. Stripe Connect): the customer pays, the system automatically separates your commission and sends the rest to the vendor. Refunds, statements and invoicing exports are included.

What about the chicken-and-egg problem — how do I get the first vendors and customers?

The proven approach is starting with a narrow niche (one city, one category), recruiting the first vendors by hand and curating supply yourself. We build the MVP to support that manual start — not to make you pay for features you'll only need in the growth phase.

Can I start with a web marketplace and add apps later?

Yes, that's the most common path. We design the backend API-first, so mobile apps plug in later without rewriting the core. Within the subscription, the expansion happens continuously — no new big-bang project.

Who owns the platform and the data if I pay a subscription?

The data is yours the whole time and the code transfers to you under the terms of your plan — unlike template marketplace platforms, where you stay permanently dependent on someone else's system and their per-transaction fees.
