Marketplace App Development

We build two-sided marketplace apps in Flutter where sellers list their products, buyers browse and buy, and both sides talk in real time, without middlemen.

What Each User Needs

Sellers

List products with photos, category, price, quantity and description, and answer buyers directly.

Buyers

Browse by category, find deals and top-rated sellers, and ask questions before they buy.

Both Sides

Switch between buying and selling in the same app, and share documents in the chat.

Your Team

An admin panel to manage users, listings, categories and orders.

Frequently Asked Questions

Can buyers and sellers chat inside the app?

Yes. On AgriFarm, buyers and farmers chat in real time about price, quantity and delivery, and can share documents such as quality certificates.

Can one person both buy and sell?

Yes. AgriFarm has buy and sell modes in the same app, so a user can switch without a second account.

Do you build for both iOS and Android?

Yes. We build in Flutter, so one codebase runs on iPhone and Android. That keeps the two versions in step and saves time compared with building two separate apps.

How long does it take, and what does it cost?

It depends on the features and the number of apps and panels. We do not publish fixed prices: tell us about your project, and we will agree the scope, the timeline and the milestones with you and send a clear quote.

Who owns the app and the source code?

You do. The app is published under your own App Store and Google Play accounts, and the source code is yours.

Can you add AI features?

Yes. We add AI where it helps your users, such as a chat assistant, voice or document reading, using OpenAI, Gemini or Claude.
