To add employees and/or independent contractors to your account you first need to open your My Account section. You'll find this by clicking on your logo in the top right of your screen, as shown below.
Then you have to scroll down and click on 'user subscriptions'. There you can choose the subscription you want your employee or IC to have and press 'Subscribe' or 'Update Seats' at the bottom of that box.
Now you can choose monthly, semi-annual or annual and select how many of these subscriptions you need and press the 'confirm the order' button.
A pop-up will appear for you to review your order. Once you have viewed your summary, you can press 'proceed to checkout'.
If you have not already added a card to your account, you will receive a message prompting you to add one. Press 'click here'.
A new pop-up will appear for you to add your card. Now you can proceed with your payment for the subscription/seat.
Once you have purchased/updated your subscription, scroll down to 'Users' on the left hand side and select either the 'New Employee or New IC' button. Once you have added the new user, you will see them in your 'Users' list as shown below.
Check mark a box next to your new user's name and then press 'allocate seat' from the new subscription you just purchased right above.
Your new user can now login with the email and password you provided when creating their new role.
