You start empty: the chicken-and-egg problem
Without supply you can't attract demand; without demand you can't win supply. Without a launch strategy, the marketplace is dead on arrival.
The challenges
Launching a marketplace isn't like launching an online store
Marketplaces have their own dynamics: trust, liquidity, split payments and discovery. These are the four challenges we see in every project.
Split payments a standard gateway can't handle
Each payment is split between the seller and the platform, which keeps its commission. Stripe Connect or Mangopay can handle that split, but it has to be integrated properly.
Search that finds nothing
Large catalogs with no useful filters (price, category, location) and no relevance ranking. Users who give up after their first search.
Zero trust between strangers
No ratings, no seller verification, no dispute process. Every transaction is pure risk — and liquidity never arrives.
Liquidity from day one
The chicken-and-egg problem, solved by design
A marketplace without sellers doesn't attract buyers; without buyers, sellers leave. Technology alone doesn't break that cycle. That's why we design the platform around the launch strategy: we identify the harder side, focus efforts on a niche or city, and give early participants the tools to succeed before everyone else arrives.
Identifying the harder side (supply or demand)
City-by-city or vertical-by-vertical launch
Assisted onboarding for the first sellers
Incentives and variable commission by phase
Key metrics (share of searches with results and of completed orders)
Targeted growth marketing support
Two-sided architecture
Sellers and buyers, connected by your marketplace
Each side has its own flows, but they share a common foundation: product catalog, orders and seller payouts. That's how we design the platform so both sides grow in parallel.
Sellers

Marketplace
Buyers
Demand

Listings
Sellers publish products; the catalog is enriched and indexed for discovery.
Orders
Buyers place orders; the marketplace collects payment and notifies each seller.
Seller payouts
The commission is withheld automatically and the rest is paid to the seller on their payout cycle.
Features
Everything a serious marketplace needs
Multi-vendor catalog, search, split payments, ratings and messaging. Every building block uses technology proven in real marketplaces.
Multi-vendor catalog
Each seller gets their own private dashboard: products, stock, prices, promotions and shipping rules.
Search and discovery
Algolia, Meilisearch or Elasticsearch with faceted filters and relevance ranking.
Split payments
Stripe Connect, Mangopay or Adyen MarketPay. Automatic commission, scheduled payouts.
Ratings and reviews
Two-way rating system with moderation, verification and seller replies.
Buyer–seller messaging
In-app chat between buyer and seller, with history, file sharing and notifications.
Payouts and reconciliation
Payment holds, holding periods, scheduled payouts and accounting reports for sellers.
Transaction flow
From listing to payout, step by step
This is how a typical transaction moves through the marketplace: optional escrow, ratings after delivery and payment to the seller on their payout cycle.
01
Listing
The seller lists a product or service, with stock, price and shipping rules.
02
Order
The buyer pays the full amount. The marketplace holds the funds and notifies the seller.
03
Escrow
The money is held until delivery is confirmed or the safety period ends.
04
Delivery and rating
Integrated logistics, tracking and two-way ratings when the transaction closes.
05
Payout
The marketplace keeps its commission; the rest is paid to the seller on their cycle.
Discovery and trust
How buyers find what they're looking for — and trust it
Search is half the marketplace; ratings are the other half. Without both working, liquidity never turns into transactions.
Relevance-based search
A dedicated index (Algolia, Meilisearch, Elasticsearch) with custom types and industry-specific synonyms. Results in milliseconds.
Faceted filters
Category, price, location and industry-specific attributes. Facets are calculated in real time from the search results.
Recommendations
Suggestions based on history, similar products and segment behavior. More matches, more conversions.
Verified ratings
Only buyers who have completed a transaction can leave a rating. Moderation, seller replies and a reputation badge.
Seller verification
Identity verification, document checks and trust indicators shown on the profile. Less fraud, higher conversion.
Disputes and returns
A clear incident flow: claim, evidence, mediation and resolution with a partial or full refund.
FAQ
Marketplace development FAQ
How much does it cost to build a marketplace?
It depends on the marketplace model, payments, search and the features for buyers and sellers. We scope a first version and give you a proposal with a defined scope, timeline and fixed price.
Which payment gateway do you use for split payments?
Mainly Stripe Connect (best cost and experience in Europe), with Mangopay and Adyen MarketPay as alternatives depending on volume and country.
What about initial liquidity? How do you get started?
We help you with the strategy: the harder side first (focus on supply or demand), city-by-city or segment-by-segment launches, and targeted growth marketing. Technology is only half the job.
Can it scale to thousands of sellers?
Yes. We design for scale: multi-tenant architecture, search with Algolia/Elasticsearch, scheduled payouts and per-seller observability.
Does it support shipping and logistics?
Yes. We integrate carriers (Sendcloud, ShipStation, Packlink) with real-time rate calculation, tracking and returns.
