How do I enter my partner code?

Go into "Firm Settings" and to the "Plans & Payment" tab.
Zola Suite will automatically select your plan (Standard vs. Solo) based on how many registered users are in your firm.
Below that, select if you'd like to subscribe annually or monthly.
Under Payment Information, enter in your credit card information. To the right, you will see a Partner Code box. Enter in your partner code and click Add.
Once you have entered all of your credit card information and applied your code, click Activate Subscription at the bottom of the page.
