Why have I not received a billing invoice?

If you are a seller and you have not received your billing invoice, please first check your spam/junk folder. 
If you have recently signed up or you are a casual seller, you may not have acquired enough sales to reach the $5 minimum ($10 minimum if you live outside of the USA) in BrickLink fees to generate an invoice. Once your seller fees reach the minimum required, you will be sent an emailed invoice for your sales on the 5th day of the following month.
If you have generated enough sales and you still cannot locate your selling invoice, please contact the Help Desk.
