Rent, bills and the weekly shop in one ledger everyone can see — with the recurring ones entered automatically.
Shared households fail at expense tracking in a specific way: the big regular costs are fine because someone set up a standing order, and everything else — the shop, the plumber, the shared streaming account — accumulates as a vague sense that someone is paying more than their share.
A shared ledger fixes the vague part. Penvo gives the household one book, everyone adds to it, recurring bills enter themselves, and settling up is a single step rather than a conversation.
One ledger for the household, separate from your own
Create a shared ledger for the flat and invite whoever lives there. Your personal spending stays in your own ledger and never mixes with it — so your food budget is your food budget, not your food budget plus a third of everyone else's.
Switching between them is one tap, and the totals stay independent.
Let the recurring bills enter themselves
Rent, utilities, broadband and the shared subscriptions are known in advance, so there is no reason to type them in every month.
Set them up once as recurring bills and Penvo records them on schedule, with a reminder the day before so nobody is surprised. Penvo will also spot repeating charges in the ledger and offer to turn them into recurring entries, which catches the ones you forgot to set up.
This is most of a household's shared spending handled without anyone touching the app.
The irregular spending is what needs capturing
The weekly shop, a replacement kettle, the taxi when the last train was cancelled. These are the ones that go unrecorded and turn into resentment.
Hold the + button and say it on the way out of the shop. Two taps on the Watch. Photograph the receipt and let the app fill in the merchant and total. The whole point is that recording an expense should be faster than remembering to do it later.
Settle monthly, not annually
Tap settle at the end of each month and Penvo works out the net transfers across everything in the ledger — who is owed, who owes, and the smallest number of payments that clears it.
Doing this monthly keeps the amounts small and the conversation short. Left for a year, the sums get big enough that people start disputing individual line items from March.
Uneven splits and people who are not in the app
Not every household splits evenly — a bigger room often pays a bigger share. Penvo's AA splitting takes a total and a number of people and tracks each person's outstanding balance, so uneven arrangements stay visible rather than living in someone's head.
Housemates who never install anything can still be named and tracked. They show up in the settlement like everyone else; they just cannot add entries themselves.
