Trendsales is an online marketplace for buying and selling 2nd-hand items.

Through our apps on iOS, Android and the web, we make it convenient for sellers to list their used items and easy for buyers to find what they are looking for. This is the discovery part of our marketplace.

To facilitate all purchases, we have built an end-to-end payment, shipping and insurance solution that is secure and fast for both sellers and buyers.

• Buyers are protected all the way from making the initial payment until after they have received their items. We even have an entire support team on standby!

• Sellers receive their money right after they have handed in their package for shipment. No address needed. Just a shipping code provided through the app. Sellers can also enable "Buy now" on their listings, making it even easier to sell.

The is the transactional part of our platform and the core of our business.

We are very proud of both the discovery and transactional parts of the platform, yet there are so many things that can be improved, expanded and added that will make the experience even better (more categories and shipping providers, personalization, recommendation engine and login-free purchases to name just a few)

Most of that centers around the backend and this is where you come in.
