I don't do that because anyone can come on here an pretend to be a great person, and a few months down the road do a chargeback or cause problems.
With invoicing there are terms of service that can be added, notes, and a clear description of what's being traded.
As I wrote in my first two posts on this thread, this is to mutually strengthen both the buyers and the seller's position in risk mitigation.
I've checked the invoice generator in Paypal, it may be a feature for non-business accounts, but on my account for invoice generating, I have to enter a dollar amount. There is no calculation offering or option to have the invoice create the correct charge. In fact, in order for that to even work, you'd have to know what country the buyer PAYS from.
Sometimes you can send an invoice to an email, and a buyer will pay with a different PayPal account. This happened before to me, but the 2nd account also showed PayPal verified and I saw his address and so I did not make a stink about it. That was before PayPal added the new distinction on invoicing if the stuff being sold is physical or digital. Now with digital selected, an address is not asked for. Which is why on my verification invoices I select physical item so that I can see the account is fully verified. It shows all this once an invoice is paid.
Keep in mind, this is not just trading beers, most of the time these are trades involving hundreds and sometimes thousands of dollars. The average risk is quite high. An even people we've known and trusted for years here can turn out to be real jerks. For example, there was a guy that would actively buy here for quite a while, but eventually, I found out he was reselling what he bought here on his eBay account for large profits. I only found out because I discovered his other username on Base.SC by chance, and then found his same handle and same ships from Base.SC on an eBay account... and low and behold... pledges he bought from here were listed on that eBay account at large profits.
My point is, if you extrapolate that to a worst-case scenario, imagine if a TEST main for years, wanted to scam for whatever reason.... if you accepted payment via friends and family, it is much easier for that person to reverse the charge. Why take the risk when it only costs a very small percentage to mitigate it? PayPal usually won't reverse a charge against a seller when you use clear invoicing with a clear TOS and can show a history of communication. Provided everything was on the up and up during the transaction, e.g. seller didn't lie and has proof (hangar log), the seller is pretty much safe.
There are rhyme and reason to my madness.
@LilleMats Welcome to TEST. About your reply on my thread, that feature is not available for me on invoicing. But thank you.
