ASAP (previously known as Waitr)..... when I was in the business and signed up for them as a restaurant owner you paid around 1500 for hardware etc. and then a precentage of the sales. Don't remember the exact number (probably around 10%) but we viewed it as worthwhile and more of an opportunity to market and scale the business than anything else. Then they started coming up with new contracts and higher percentages but the kicker was the contract you signed said you could not charge more for their service. So whatever you charged for dining in was the max you could charge for their service. Most restaurants have very slim margins. When they did that was when Waitr hit a brick wall. Lots of customers, including us, told them to bit it and dropped them. Obviously the policy changed. In general the delivery services across the board now charge a 20-30% fee on top of the restaurants "normal" prices to the restuarant. They can then tack on even more fees to the customer ultimately bringing their margins into the 35-50% range. Of course you also want to tip the delivery person.....so....
p.s. - Waitr was started in Lake Charles and then moved headquarters to Lafayette as they were scaling up. Pretty sure that anyone who was part of the original startup is long gone at this stage.
