About This Service

A two-sided business needs a platform serving both sides

Sellers need onboarding, listing tools, order management and transparent payouts, while buyers need trustworthy search, reliable reviews and a consistent experience whoever fulfils the order. We build the commission engine, escrow and payout mechanics correctly, because that is where marketplaces create legal and financial exposure when handled loosely. Both the storefront and the seller portal are built together, since neither is useful alone.

Why Choose Chambrix

We get the money mechanics right first

Commission, escrow and payout logic is where marketplaces most often create exposure, so we agree the model in writing and build it to keep you outside the regulatory perimeter.

Commission Engine

Flexible rates by category, seller tier or volume, calculated and recorded on every transaction.

Financial Compliance

Escrow and payouts handled through a marketplace-ready provider, not held by you directly.

Trust And Safety

Review moderation, dispute handling and fraud signals protecting buyers and honest sellers.

What guides our marketplace work

Principles for platforms that scale on seller growth rather than headcount.
Scale Without Stock
Catalogue grows through seller acquisition rather than your own inventory investment.
Sellers Self-Serve
Proper onboarding and tooling means growth does not require proportionate headcount.
Recurring Commission
Revenue scales with total platform volume, not only with your own direct sales.
Meaningful Ratings
Moderation and verification keep reviews trustworthy for buyers and fair to sellers.

Marketplace Development — Questions

Straight answers to what clients ask most

How do you handle payments to sellers?
Through a payment provider with marketplace support, which handles split payments, escrow and seller verification. This keeps you outside the regulatory perimeter of holding client funds yourself.
What is the hardest part of launching a marketplace?
The cold-start problem. Buyers will not come without sellers and sellers will not come without buyers. That is a go-to-market challenge more than a technical one, and it should shape your launch plan before the build starts.
Can sellers manage their own listings?
Yes. The seller portal covers listings, inventory, orders, shipping and payout history, with an approval workflow where you want oversight.
How do you prevent fraud?
Seller verification at onboarding, transaction monitoring, payout hold periods on new sellers, and review moderation to keep ratings meaningful.
