I think in a full build out, being able to manage forms+billing through a "developer account" that allows me to manage their stuff would be nice.

I would _especially_ like that the developer account gets like 3 free forms as long as clients are paying.

This idea needs exploring. It is good, but a little bit complicated.

I think there are 2 situations: - 1 client is not technical at all - so you manage on your acc - client is ok with having their own acc, then it is much better option

That makes sense. Are you currently using something more involved, e.g. Form Spree?

nope
