Hi @hanrina, Celine from the Community Support team at Figma here. Thanks for reaching out, and I can see you've already contacted our support team, hanks for doing that.
For security and privacy reasons, we're not able to discuss account-specific billing details here on the Forum. That said, our support team has already shared a detailed breakdown of your invoice in your support case. Please check your inbox for the full explanation.
(In general, this type of invoice can be generated when a user is granted Can edit access during a billing cycle, as assigning edit access creates a paid Full seat for users who don't already have one on the team. The invoice in your case was a catch-up invoice rather than a subscription renewal.
I can also confirm that your team has been successfully cancelled, so there won't be any future renewal charges for it.)
If you have any further questions about your billing request, please continue the conversation directly through your existing support case, as the support team will be best placed to assist you. I'll go ahead and close this topic here, thank you!
