Subaccounts can be added only starting from our Team plan, which already comes with 2 additional user licenses. However, if you need to create more subaccounts, you will need to purchase them.
The price for a subaccount is $25/month on the monthly subscription and $20/month (billed yearly) on the yearly subscription. With the Team plan, you can expand up to 10 subaccounts. If you are looking to add more subaccounts for your business, our custom corporate plans can accommodate your needs. Get in touch with our Enterprise team for more information.
To see a detailed description of the 123 Form Builder plans, have a look at our Features list.
Please feel free to contact us when you want to start adding subaccounts.
