My buyer arranged purchase through messages and didn't mark it 'sold' online. Can I do it?

How can I mark something 'sold' if my buyer paid cash and picked up before I realised he had to mark it as sold online. I haven't done this for a couple of years and forgot how it works. So it's still marked as active and I am getting offers I don't need! I have messaged him and asked him to do it but no response today. I have to apologise and tell bvuyers it's sold but I can't seem to update it from the seller listing. Help!!

Just curious here, if the buy/bid button has not been hit, would this not mean that it is an off Ebay transaction???
