How to read your result
The big number is rent. It's what the commission line costs you per year over the flat-rate alternative, on volume you already do. It buys no equipment, no staff, no lease — and the customer list it generates belongs to the platform, not to you.
Percentage fees punish your best orders. A flat $7 costs the same on a $20 ticket and an $80 ticket. A 25% commission costs $5 on the first and $20 on the second. That's why the break-even ticket matters: above it, every dollar of ticket growth widens the gap in the flat fee's favor.
Treat the number as a ceiling, not a forecast. Not every app order can move direct — strangers who found you on the app stay on the app, and that's fine. The realistic slice is your regulars. If even half your app volume is repeat customers, half this number is margin sitting on the table. The apps are a discovery channel. They're a bad landlord.
