Add-on payments and billing dates
Add-ons are billed in advance, with the first payment charged at the time of subscription. After that, you'll be billed automatically every month based on your subscription start date.
* If your subscription date falls on the end of the month (the 29th, 30th, or 31st), the renewal and payment will take place on the last day of any month that doesn't have that date.
Payment example
Item | Example date |
Project plan subscription date | 3/16/2024 |
Add-on subscription date | 5/31/2024 |
Add-on first billing date | 5/31/2024 |
Future add-on billing dates | The 31st of every month starting 6/30/2024 |

Add-ons are billed in advance, with the first payment charged at the time of subscription.
The first bill is issued at subscription, and the amount for the first month is prorated.
From the following month, you'll be billed on the same day each month as your project plan payment date.
* If your project plan subscription date doesn't exist in a given month, you'll be billed on the last day of that month.
* Even if the project is on an annual plan, add-ons are subscribed and billed monthly.
