Not to stop you from doing this because competition is good for businesses, but this exists. ChowNow is a commision-free piece of software anyone can buy for a flat monthly fee. Slice is a pizza-focussed app that charges a flat fee per delivery. I have no idea why they're so focussed on pizza rather than the general market, but do what you know, I guess.

Former Slice user here. They're focused on pizza only because they started as a pizzeria in Staten Island. They know their vertical. Part of the mission is specifically to help pizzerias.

I only stopped using them because I moved away from NYC.
