Guides
Seven cases, seven set-ups — each one a quarter of an hour's work. Every guide walks from the empty group to a finished settlement suggestion, and says plainly where the limits are.
Shared gift
One person buys, everybody chips in. Invite colleagues without an account, set the shares, settle up.
Holiday or trip
Many expenses, changing payers. Weight the shares, record as you go, settle at the end in a handful of transfers.
Flatshare
No beginning, no end. Separate groups per cost type, shares by room size, settle monthly.
Utility costs
One group per billing year, shares by floor area, metered use as a fixed amount, advance payments cleanly recorded.
Move-in budget
A fixed amount spent down over several weeks before you move in. Agree a cap, record invoices as they land, check the total before it's gone.
Business at home
Part of the floor area is used for a business. The share by square metres, the business as a member, one figure at the end of the year.
Collecting for one bill
One cost, and a group that keeps growing. A pledge as a fixed amount, everybody else on a percentage of the rest — and every new member lowers what the others owe.
