4RSale: a local marketplace app for buying, selling and renting
ScalaCode built 4RSale, a marketplace app for buying, selling and renting locally. Sellers list and manage products, buyers search, pay and track orders, and both sides contact each other inside the app on iOS and Android.
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.
What a local marketplace has to solve
Trust between users
Buyers and sellers who have never met needed reasons to trust each other and an easy way to talk.
One app for iOS and Android
The platform had to run securely on both mobile platforms.
Quick, secure payments
Transactions needed a reliable payment system that completes quickly and safely.
