Can I use Jotform for multiple (different businesses?)

Yes, I believe you can. May I suggest you check our Templates page? There you will be able to see different kind of forms that you can use or may give you an idea on how you can create your form from the form builder page.

Hi Mike!
Thank you so much for your help. Could you please find out for sure if I
can use it for different businesses independent of eachother?
Thanks!

I can confirm that you can use it for different businesses independent of each other. You can choose to create several accounts for each business, or create one account and create the forms for each of your businesses from there. You can categorize each form that you create for your business by assigning them in each folder. Here's our guide on How to Add or Group Your Forms into Folders.

If you need further assistance, feel free to contact us again.
