Ive used this to sell on prem at 5 and 6 figures, bootstrapped solo founder.
I’ve been lucky to have good customers and be a good vendor so that never mattered. If things go bad it might not be good enough .
If you are bootstrapped, just do it. Having on-prem cash in your account will make you happier and free you to make better decisions later. Your lawyers can fix the mess if one happens
