What if I only sell services?

[Spoklahoma01]

I am working on starting my own bicycle Courier & Delivery service. I noticed there’s no add services option? What about services instead of items? Why can’t I keep track of things done with cash?

you can use services too.  just call the item "4 mile delivery" or whatever and set the price.

you can track cash sales with the Square POS app.
