Building a two-sided marketplace app
What it takes to build a marketplace connecting buyers and sellers, from listings and search to payments and trust.
EvoAstra team14 Nov 2026 · 3 min read- A marketplace is really three products: buyer app, seller app and admin
- Trust features such as verification and reviews are essential
- Solve the chicken-and-egg problem with a focused niche
Marketplaces such as job platforms, classifieds and service booking apps connect two groups of people. They are rewarding to build and challenging to get right, because both sides must find value at once.

Three products in one
- Buyer side: search, filters, listing pages, chat, payments and reviews
- Seller side: create listings, manage enquiries, payouts and performance
- Admin: approve listings, handle disputes, manage categories and see reports
Trust and safety
Verification of phone numbers, documents or businesses; reviews and ratings; reporting tools; and moderation of listings protect both sides and keep quality high.
Payments
Some marketplaces take payment and release it to sellers after delivery, which needs careful handling of payouts and compliance. Others simply connect people and charge for listings or subscriptions. Choose the model before building.
Start narrow
A marketplace needs enough buyers and sellers in one place to work. Start with one city, one category or one community, and expand once it works there.
