Zelle as the main payment processor?

Has anyone here used Zelle as a primary customer payment system?

I recently opened a business checking account from US Bank specifically because it offers Zelle for Business. I currently use ACH for ongoing monthly fees from my bookkeeping clients, but I'm looking at a new business venture that would benefit from low fees on $200 average sale. Plus, who doesn't want quick funds availability right?!

I'd like to just send an invoice and include a pay link or take payment on the spot using a QR code.
