Hello,
Thank you for contacting Rank Math support today and bringing your concern to our attention.
The renewal is charged annually but unfortunately, it is done automatically since our payment system is handled by our 3rd party payment gateway FastSpring.
You can however request an invoice upon being charged in your renewal.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Hello,
Since we did not hear back from you for 15 days, we are assuming that you found the solution. We are closing this support ticket.
If you still need assistance or any other help, please feel free to open a new support ticket, and we will be more than happy to assist.
Thank you.
