Create an account. Paste the script. Connect Stripe.
That is the public signup copy. Not a tag manager. Not a warehouse. Not a sales call. Self-serve, no waitlist.
After that the loop is: visitor lands, first touch is kept once, they pay in Stripe, you get one line. If I have to sit in that loop, the install failed.
This is fast only if you already charge on Stripe and you can paste a script tag. If those two are not true, the three steps are not three steps. I will not invent a setup-time number. The site does not publish one I would stand behind.
Support, if you need it, is inside the Motif account.
Which of the three steps is the one you would actually stall on?
I build Motif (MotifTrace). It is at motiftrace.com. Free until the answer changes what you buy.
