Marketplace Development

A marketplace is three products in one: the sellers' storefront, the buyers' journey, and the back-office orchestrating both. LaMeDuSe builds custom B2B and B2C marketplaces, with the logistics and billing that go along.

The problem you're facing

Turnkey marketplace solutions lock you in: commissions on every transaction, limited customisation, and your differentiation capped by available modules. At the first specific need, the platform becomes an obstacle.

Our answer

We build your marketplace from scratch: catalogue, search, orders, payments, reputation, disputes : every business rule is yours. You own the platform, the brand and the customer relationship, with no commission on your revenue.

What LaMeDuSe takes care of

  • Seller journey: onboarding, catalogue, offer management
  • Buyer journey: search, order, payment, tracking
  • Secure payments and split payment flows
  • Moderation, dispute and refund back-office
  • Ratings and reputation system
  • Seller dashboards and administration
  • Scalable infrastructure for traffic peaks

Security

Systematic code review, secrets management, monitored dependencies and security testing built into the development cycle : security is a starting requirement, not an option.

Hosting & infrastructure

We host your applications on our own European infrastructure (France, Germany, Switzerland): development and operations are carried by the same group, with no dependency on US cloud.

Maintenance

Application maintenance contracts covering bug fixes, upgrades, feature evolution and user support : the team that designed the software is the team that keeps it alive.

Why LaMeDuSe

Building a marketplace also means securing financial flows: our track record in secure hosting and operations in Europe guarantees that the platform processing your users' payments is seriously monitored.

Frequently asked questions

A complete marketplace typically starts around €80,000. We recommend starting with one vertical or a limited geography, with a deliberately narrow scope, to validate the supply/demand balance before extending.

Through licensed payment providers (Stripe Connect or equivalent) who handle compliance and fund splitting. The marketplace never directly handles the money : the licensed provider does, within the regulatory framework.

A turnkey (SaaS e-commerce) platform suits testing a standard market. Custom is required when your value comes from specific business rules, an original commission model or integrations with your ecosystem.

That's a commercial animation topic, not just a technical one. We design the platform to foster network effects (simple onboarding, storefront quality) and support you on bootstrap mechanics.
