In simple words a sub-account is another Jotform account that you connect with yours to share access to your forms and to your form's submissions. However to have a deeper knowledge about what a Sub-account is and how it works, please refer this guide: How to Share Forms with a Sub-Account User
The limit number of sub-accounts you can have depends on the plan you got. You can see the details about the limit of Sub-user accounts per each plan at our PRICING page.
