How we check the math

Every money figure in the app — the dashboard, a night’s settlement sheet, payouts, per diems, the accountant export — comes out of the same calculation engine. Screens don’t keep their own copy of the math. And once a week a robot opens every one of those screens for the same test tour and checks they all show the same numbers.

We built a realistic 8-night test tour: six shows and two days off, ten people on five different kinds of pay, merch with card fees and tips, a deposit to the agency, a crew member paid back for gear, and a cash count that came up short. Every night’s numbers were worked out by hand from the written rules — never by running the app — and a separate audit rebuilt the whole tour from scratch and got the same answers. The engine matches every figure to the cent, and that check runs again on every change we ship.

During a full audit of the money engine in September 2026, we generated 20,000 random tours and checked that the books balance on every one: what the band splits always adds back up to the tour’s net. The biggest gap anywhere was about a hundred-billionth of a dollar — rounding dust that never reaches a cent on screen.Now 400 more random tours — odd deals, door bonuses, merch splits, card fees, tips, deposits, withheld tax, reimbursements and every kind of pay — go through the same checks on every change we ship. So do one-dollar tests: put a dollar into a tour (a cash guarantee, a card sale, a deposit, a Zelle payment) and it has to land in exactly the right place, once. That’s how we check that money is never created or lost.

Every Monday, a robot tour manager signs up, creates that test tour, adds the band and crew, and enters all 8 nights through the app on a simulated iPhone — the same screens and buttons a real TM taps. After each night it checks the dashboard’s net and cash against the hand-worked numbers, and at the end, everyone’s pay. It runs in a private test copy of the app, never on your data, and if a single number is off, we get an alert.

Every change to a money record — a night’s settlement, an expense, a deposit, a per diem handed out, a cash count, a pay rate, a payout marked paid — is recorded with who made it, when, and what it said before. The tour’s owner reads it on the Money history screen, and it can’t be edited through the app. If a wrong number is ever saved over a right one, the trail shows exactly what changed, so it can be put back.

Money access is a switch you control for each person. Without it, crew get the day sheet, the schedule, the headcount and their own pay and per diems — never the tour’s gross, net, anyone else’s pay or the balances. (A Tour Manager always has money access; that’s the job.) It’s enforced by the database itself, not just hidden on screen: every night an automated test signs in as a crew member, asks the server for the money directly, and fails if anything comes back.
