Buyer sent funds rather than pay invoice, how to correct?

[fogebotom]

How do I go about getting the funds that a buyer sent to pay the invoice I sent? So that it doesn't delay the shipping of her package? 

[Whac-A-Mole]

you can refund her and ask her to pay by the invoice

[fogebotom]

Did that once already, that delays her paying the actual invoice by another 2-3 days.   I have a small window to ship due to traveling on business.   

I've contacted her and directed her to call Paypal directly to get the payment switched.   I won't cancel the invoice as it has the terms of the agreement on there.

[Whac-A-Mole]

Paypal is not going to switch payment for you.

just go ahead and ship with tracking,if she files a dispute,thats what you need is tracking and signed for if $750 or more.

as to terms,it wont stand if she files item not as described,it trumps your policy.

if she loses,she canf ile charegback with her cc issuer.
