Hello,

I would like to ask for clarification regarding my recent billing.

On March 9, I paid $16.50 for a Dev Seat, which should cover the billing period until April 8.
The invoice code for that payment is LYKGRSYB-0001.

While working in my workspace, I accidentally upgraded a team member to a Full Seat.
I understand that this action was my mistake, and I am not requesting a refund for the seat upgrade itself.

However, I noticed that my upcoming invoice shows a charge of $40 for two Full Seats on April 9.

Since I had already paid for the Dev Seat on March 9, I expected that upgrading to a Full Seat during the same billing cycle would only charge the prorated difference between the Dev Seat and the Full Seat, rather than a full additional charge.

Because of this, I would like to confirm whether the current billing correctly reflects the previously paid Dev Seat period (March 9 – April 8).

Could you please help review this billing and clarify:

• Why the $40 charge for two Full Seats appears on April 9

• Whether the remaining paid period from the Dev Seat has been accounted for

• If any prorated adjustment or billing correction should apply

For reference, the related invoice code is LYKGRSYB-0001

Thank you for your help and clarification.

Best regards.
