Roommate expenses

Shared bills with roommates, settled without asking twice

Living with people you did not grow up with means the money has to be explicit. Rent, the internet, the shop somebody did on the way home — each one is its own expense, and each person is one running balance everybody can see.

The three things flatshares actually argue about

Not the amounts. The costs nobody wrote down, the ones that were never really equal, and the month somebody moves out.

Rent and the bills that repeat

Enter the rent, the internet and the standing contracts once. They turn up already split each month, on the day they are due, so there is no monthly round of reminders. The free plan carries three recurring expenses; Premium lifts the limit for the whole household.

Rooms that are not the same size

A flat where one room is twice the other is not an even split, and pretending it is quietly makes somebody resent the arrangement. Split the rent by shares or by exact amounts and the ledger says what everybody actually agreed to.

Who bought what, and who owes for it

Ticked items from the shared list become a shopping trip with a buyer against it. Correct the buyer or the per-person shares and the linked expense re-splits itself, so nobody has to reconstruct a receipt from memory.

Every shop, with a name on it

The trip history is the answer to “who paid for the coffee last time”. Each finished trip keeps what was bought, who bought it and what it cost, and the expense it created links back to it. That is what makes a balance checkable instead of something one person has to be believed about. Free households keep the recent months of trip history; Premium keeps all of it.

Three flats that look like this

Four people, one flat, four different paydays

The rent leaves one account on the 1st and everybody squares up afterwards. OctoFlat holds the balance in between, so the person who fronted it is not also the person chasing it.

A couple and a lodger

Some costs belong to the whole flat and some only to the couple. An expense is split between the people it applies to and nobody else, so the lodger is not quietly paying a share of the sofa.

When one room turns over

A flatshare is rarely the same four people two years running. Somebody who leaves stays attached to the expenses they were part of, and whoever takes the room starts at zero instead of inheriting a balance they never agreed to.

What it costs to run a flatshare on this

Nothing, for as many flatmates and as many households as you need. The free plan includes three recurring expenses, two budgets and ten manual expenses a day; Premium lifts all three — and it belongs to the household, so one flatmate subscribing covers everybody in it.

Questions about sharing a flat

Do all my flatmates need the app for this to work?

To be split against, yes: an expense divides between members of the household, and a member is somebody with an account. It is a short job — you send the invite link, they install OctoFlat and join, and the balances that already exist are on their phone.

What if one flatmate never settles up?

The balance keeps saying so, which is most of the work. The amount is exact, per person and per currency, it is visible to everybody rather than being one person’s claim, and settling it is a PayPal link and a single tap.
