Marketplace Development Services
We build and run marketplaces where every seller is paid exactly once, and commissions, payouts and refunds agree with your books.
Two ways to a marketplace.
Your marketplace is the business
A local or specialist marketplace, often backed by a parent group, a public body or investors, launching or relaunching on rules of its own.
You open your platform to other sellers
A distributor or retailer adding brands and suppliers to its own store or trade portal, for more range without more stock.
A marketplace that runs on your rules.
Seller onboarding
Sellers apply, your team approves them, and they manage their own listings, prices and orders.
Seller storefronts
Each seller can run a branded storefront of their own, all on one platform and in many languages.
Your selling logic
Custom products, trade pricing, bookings or approvals: whatever makes your marketplace different from a template.
Commissions and payouts
Commission worked out on each order, held until the order is safe, then paid to each seller in batches.
Delivery through suppliers
Digital goods and services delivered through supplier connections, retried safely and checked every few minutes.
Admin and audit trail
One console for your team: sellers, orders, failed payments and payouts, with every money event kept on record.
Medusa runs the commerce and Mercur adds sellers, commissions and payouts. Sellers are paid through providers such as Stripe Connect, chosen for the countries you serve.
Marketplaces we have built.
Dazway: reseller marketplace
Client Dazway, a marketplace for airtime and gift cards across Africa.
Delivered 2026Situation
Resellers sell airtime and vouchers that can’t be recalled once delivered, each from a branded storefront, across countries and currencies.
What we built
Storefronts in 13 languages, a reseller portal and an admin console on Medusa and Mercur, delivery with safe retries, and commissions calculated on true cost, held, batched and paid out seller by seller.
Pixerf: creative marketplace
Client Pixerf, a marketplace for visual content in Singapore.
DeliveredSituation
Brands and agencies wanted authentic Asian visual content, and regional creators needed a way to earn from it at scale.
What we built
The marketplace from scratch: creative missions with prize payouts, photographer bookings, licensing at purchase, and earnings and rankings for 50,000+ creators.
Architecture first, then a running system.
Already selling online? We can open your existing store or trade portal to other sellers.
Technical plan
Our senior architects follow the money from buyer to seller to you, map your selling logic and each country’s rules, then write the plan: what to build, the risks, the timeline.
Prototype
A working slice on your own sellers and products, with payouts run end to end in test mode, so every decision is confirmed before the build.
Build
In stages: a first version goes live with real sellers, and each phase adds to it.
Run
We host, monitor and update it, and watch the payouts, for as long as the marketplace is in service.

Frequently asked questions
Should we build our own marketplace or use a hosted platform?
A hosted platform gets a simple marketplace live quickly. Your own pays off when you have selling rules of your own, sellers in several countries, or a parent business to connect to.
Why Medusa and Mercur?
Medusa is an open-source commerce engine, and Mercur adds sellers, commissions and payouts on top. Both are built to be extended, so your selling logic sits in the core instead of in workarounds.
How do sellers get paid?
Through a payout provider set up for the countries you serve, such as Stripe Connect. Where one provider can’t reach every market, we connect more than one.
Can we open our existing store or portal to other sellers?
Yes. Sellers are added beside your own products, and their sales and payouts are kept separate from yours.
What about seller checks, e-invoices and tax?
We design them in from the start: seller verification, record-keeping, an e-invoice for each payout where required, and tax held back where the law asks. Your tax adviser sets the rules; we build to them.
Can you take over a marketplace we already run?
Yes. We start by reviewing the current platform and how money moves through it, then move sellers, listings and balances across in stages.
Who owns the code?
You do: the code, your seller data and the documentation. There is no licence fee per seller.
