When the client is a brand new LLC
Plenty of good clients are young. A founder who formed an LLC two months ago may be a perfect fit and may pay on time. ClientVetter does not punish youth on its own. A thin footprint is shown as a signal with an explanation, so you see the difference between "new company with a real website, working mail and an active registry record" and "new domain, no registry match, no mail records".
For young clients the suggested terms usually lean toward a deposit and smaller milestones. That protects you without insulting the client, and most legitimate businesses accept it without a second thought.
If you want to look at the registry side yourself, our llc lookup guide explains what each status value means.
