Regarding grubhub, to be honest I would consider embracing it… as much as it’s annoying to deal with. They just merged with Seamless a couple months ago (ontop of aquiring eat24) creating the largest user database in the market. I did some recent analysis and our volume through the channel is up 20% since the merge. We even have <4 star Yelp ratings but our online grubhub orders through yelp, tripadvisor, etc. for NEW customers is present. Just through don’t ever give discounts, let NEW customers know discounts and value orders are on your website (and your loyalty/marketing system)… i.e. communication on pizza box.
The worst in my opinion is doordash. Without your permission, they post your menu, weeknight value deals (on the wrong days) and prices and don’t update prices. Charge your customers a $4-5 fee. No big deal if it brings in volume, however when customers call your store asking about an order or an issue… literally no visibility into what is happening. You can call them directly and disable.
p.s. “Slice” sucks… unless you really need online ordering and dont want to deal with a website. I tried them and turned them off. Minimal user database… and weird value prop (how many new customers could you aquire from a database that only involves pizza restaurants?)
