With Flatify, you can easily track the debts within your shared apartment. For each roommate, it shows how much you owe them or how much they owe you. Sometimes, debts can accumulate, and you might want to pay back only a portion. This is entirely possible. Here's how you can do it:

1. Go to the 'Payments' page.
2. Click on the person you want to repay.
3. Click on 'Settle Debt,' which opens a new window displaying the amount you owe to your roommate.
4. Click on the amount.
5. You can now enter the amount you're repaying, and the remaining debt will continue to exist.
