4RSale, a marketplace for local buying and selling

4RSale wanted to make local commerce simpler. Sellers needed an easy way to list and manage products, and buyers and sellers needed a trustworthy way to communicate. The project started in 2021 with Manuel, the company's CEO.

The challenge

What a local marketplace has to solve

1

Trust between users

Buyers and sellers who have never met needed reasons to trust each other and an easy way to talk.

2

One app for iOS and Android

The platform had to run securely on both mobile platforms.

3

Quick, secure payments

Transactions needed a reliable payment system that completes quickly and safely.
