In every share house there's a silent subsidy. One person notices the dish soap is out, buys it, and doesn't bother claiming A$4.50 back because it feels petty. Then it's bin bags. Then the mop. Six months in, they've spent a couple of hundred dollars on the house and said nothing — until the day they say everything, usually about something unrelated, and everyone's confused about where the resentment came from.
The old fix is the kitty: a jar, or one person's card, that everyone theoretically tops up. In practice the jar has A$7 and an IOU in it, nobody remembers who's paid in, and the person "holding" the kitty is now doing bookkeeping for the privilege of buying everyone's sponges.
Why the jar (and the group chat) can't do it
A fund only works when three things are visible to everyone: who's put in, what's been spent, and what's left. A jar shows none of them. A chat thread shows fragments of all three, scattered across four months of memes. So the fund quietly collapses back into "whoever cares most, pays most" — which is exactly the thing it was meant to fix.
A fund with a ledger, not a jar
FairMate's house shares have the fund built into the same Deposit & fund tab that tracks your deposit. The house sets a standard contribution — say A$50 each to start, topped up when it runs low — and every payment in and purchase out is a dated, named entry. The balance is always current, always visible to the whole house, and never lives in one person's head or bank account alone.
Open your house share → Deposit & fund → house fund. Record top-ups per housemate, log purchases against the fund as they happen, and let everyone watch the same balance. Snap the receipt with the free Smart Receipt Scan and the amount fills itself in.
A worked example
| Fund top-up — 4 housemates × A$50 | A$200.00 |
| Cleaning supplies (Woolies run) | −A$46.00 |
| Shared groceries — oil, rice, spices | −A$74.00 |
| New mop & bucket | −A$28.00 |
| Fund balance | A$52.00 |
Three purchases, three entries, one visible balance. When it dips low, the app's the one saying "time to top up A$50 each" — not a housemate having to play treasurer.
The quiet payoff: leaving is clean
Because contributions are on the record, the fund stops being a problem when someone moves out. Their unspent share is part of the same move-out settlement as their deposit — worked out from entries, not estimates. And day to day, the fund covers the shared basics while your actual bills — rent, power, internet — run through the normal monthly splits, netted into the fewest possible payments. One house, one place where all of its money makes sense. If you're still weighing up apps, the comparison page shows how rare built-in fund tracking is.
Three ground rules that keep a fund healthy
The ledger does the bookkeeping, but a house still needs a tiny bit of policy. The funds that survive tend to agree these up front:
- Decide what's fund, what's split. The fund is for things the house consumes — cleaning gear, bin bags, shared pantry staples. A grocery run for Tuesday's dinner is a normal split among whoever's eating. Blur the line and someone ends up funding other people's snacks.
- Top up by trigger, not by month. "A$50 each when the balance drops under A$40" beats a monthly ritual people forget. Because the balance is visible to everyone, the trigger is too — the app's numbers do the nagging.
- Receipt everything, effortlessly. A fund only stays trusted while purchases stay visible. The scan makes that a five-second habit instead of a chore, which is the difference between a ledger and a mystery.
None of this needs a house meeting or a treasurer. It needs one shared screen everyone believes — and a norm that the person buying the mop is a hero doing five seconds of admin, not a martyr doing everyone's books.
