what guidelines should i follow

[john]

Well first of all get in touch with the other party through a messenger or something while carrying out the transaction and then do not mention anyhting about conversion in the details section while paying through Paypal.

no actually i'm selling some thing and he will pay through paypal dont know what should i follow infact i have written to paypal to clear their guidelines about seller protection.

If you are selling something online, if possible send a online invoice to your buyer about the item your buyer purchase. This will be your proof in future if your buyer using chargeback policy to you. You will be well protected with this, as ebay also doing the same way to make sure buyer paid.

eddie is right always send invoice and let the other party to accept it and pay with this procedure paypal can't refund your money.

so if the puchaser said he never received any invoice and never receive the prodcuts. what could we do then?

well paypal itself has copy of invoice in your recent account activity so no need to keep ,still you can keep that mail.It is a safe way to deal with fraud people who claim charge back,if some body not accepting invoice then dont make transaction with him/her.
