Records that can't be quietly edited
Once a decision is approved it is sealed. Corrections are made as new entries, so the history of a building's spending stays readable years later — including by the next committee.
Two people, never one
Whoever raises a charge cannot be the one who approves it. The separation is enforced in the system, so it holds even when everyone is busy and nobody is watching.
Residents' money kept apart
Building funds are held separately from company funds, and statements are derived from the ledger rather than typed into a spreadsheet at the end of the month.
Built for buildings where residents don't all read the same language, with right-to-left layouts treated as native rather than translated.
