Sending invoice for Digital Goods

[ziemlaj]

Hello everyone. 

I dont want to make anymore mistakes, using my paypal account, as my account was just fully restored. Let me explain you what I need to know. I'm sending invoices to my customers for digital goods. Once they paid for the goods, I have an option to check "mark as sent" . I really dont know if i should check it if i dont have a tracking number and goods were delivered to my customer. Should I check it "mark as sent" or not? Thanks in advance for any response!

It's basically a moot point.  You can mark as sent but, it really does not matter.  Intangible goods such as digital goods are not covered for Seller Protection or Buyer Protection.  All you're doing is taking a risk and hoping you're dealing with an honest customer.
