Note: You have to be the Account Owner to do this.
You're running out of signatures? Don't worry! You can add additional signatures to your current plan. That means you dont have to change your subscription just because you need more signatures.
You can purchase additional signatures in your Plan & Billing settings in your account. The additional signatures will be immediately available after you have confirmed your purchase.
Your options
You can choose between different top-up option:
100 signatures

1000 signatures
Tip: If you often exceed your plan’s limit, it might be more cost-effective to upgrade your plan instead of topping up.
