YOUR HOME, YOUR WAY

Choose the one that works for your household when you create your home.

ONE PERSON HANDLES THE BILLS

One person pays and collects

One person pays the bills, and everyone else gets a clear monthly statement. Advances are deducted or reimbursed.

FOR THE PEOPLE WHO SHARE A HOME

Every home has its own way.

As a couple, a family, a group of friends or a co-living household. Flatkin helps you organise what you share.

  • Couples
  • Families
  • Friends
  • Co-living

HOW IT WORKS

One shared place. Three first steps.

  1. 1

    Create your home

    Choose your money mode, currency, language and time zone.

  2. 2

    Invite with a link

    The home admin sends each person their own link to join the home.

  3. 3

    Add an expense and split it

    Record expenses and who shares them. Add your chores and plans, too.

CLEAR EXPECTATIONS, LESS GUESSWORK

Know where you stand from the start.

Recording a payment doesn’t move money

Flatkin keeps the records. You make the actual payments outside Flatkin.

Notifications for the people involved

In the iPhone and Android apps, people in a new expense’s split can receive an alert if they have notifications enabled. The person who added it won’t receive one.
