How long do I wait for payment? Newbie

[christmashope]

Hi guys
I sold my very first item on ebay, not expensive just over £8 plus postage, the bidding ended on Sunday morning at 0830hrs. I sent the buyer an email saying I would post as soon as I received payment (email sent on Sunday 0900hrs) no reply... I have already sent them an invoice.
I have no idea what to do now if I don't receive payment, or how long I wait to hear from them.
Many thanks in advance

2 days, so tomorrow 8.31 start the unpaid item process. This gives them another 4 days to pay. Then if no payment close case, add to blocked bidder list and relist or second chance offer.

And ending items in the evening - 9pm ish, normally gets more bidders. Sunday morning not many around, or awake, to bid.

Go here & follow directions to say you haven't been paid. After 4 full days you can close the case & relist (do not try to relist before then, and if buyer pays up after all then be very professional about it).

Many thanks for your messages. I opened an unpaid item request then 3 days later they paid. Thanks for your help
