Set the recurring bills once

The same bills, the same friction, every month

Shared households have a stable core of costs: rent, Wi-Fi, electricity, the streaming subscriptions nobody wants to cancel. These never change much — yet many groups re-negotiate them from scratch every single month, chasing shares over text.

Recurring costs should be set once and then just happen. The mental energy is better spent on the variable stuff.

Decide the rules up front

• --Who pays the biller, and who reimburses whom — fix this once.
• --The split method per bill (rent by room, Wi-Fi evenly, streaming by who uses it).
• --The day of the month each one lands, so nobody's surprised.

Write it down in the shared ledger, not in someone's head. A recurring entry that auto-appears each month means the bill is acknowledged before anyone has to ask.

Handle the edge cases before they become arguments

What happens when someone travels for three weeks — do they still pay full Wi-Fi? When a flatmate moves out mid-cycle? Agree the “fair enough” answer in advance. Most disputes aren't about money; they're about a rule that was never set.
