Every family that ties allowance to chores ends up running a small, undocumented payroll system — from memory, weeks in arrears, with disputes settled by whoever remembers loudest. The chore was done or it wasn't; the money moved or it didn't. That's a ledger, and ledgers belong in writing.
A chore can carry a payout
In Sherpsy, a chore has effort points, and it can also have a dollar amount. Mark it done and the amount lands in the earner's balance. If you want oversight, flip on approval — the completion sits as pending until a parent confirms it, with room for a proof photo when "I cleaned my room" needs evidence.
Spend, Save, Give
Earnings split across three jars — Spend, Save, Give — in whatever percentages your family sets. Settling up is explicit: a parent marks a payout, and the ledger records it. The next argument about whether June's allowance was ever actually paid has a written answer.
None of this makes chores fun. It makes them fair — the streaks are visible, the load balance across the family is visible, and the money is arithmetic instead of memory.
The chore chart was never the hard part. The payroll was.
