Add-ons extend your plan: more capacity or an extra module. Settings › Subscription lists the add-ons that work with your plan, and your current quantities.
- Adding or increasing: you pay a checkout invoice for the remainder of your current period only. The add-on starts when it is paid, or provisionally on a valid receipt.
- Decreasing or removing: scheduled for the end of your current period, and can be undone until then.
- During a trial, add-ons that offer a trial can be tried for free.
- Each add-on has a minimum and a maximum quantity, shown when you change it.
A few add-ons are arranged with us rather than bought directly; they show “Contact sales” instead of a price.
