You can make profit in the game. To this, you need to sell all the items that you have in your inventory.

However, it's not so easy to sell all your items, so you need to use the Trader's Box. This is a mod that lets you trade all sellable items at Trader's prices.

On top of that, the Trader's Box also works as a vending machine with daily stock updates. In this way, you can sell all your items and get daily profit.

If you start a new game and complete all initial quests, there will be another quest called "Job for a Trader".
