I'm currently in the transaction facilitation industry
Well, based on your posts: you shouldn't be. You'll either get scammed, or you'll scam someone else.
I was looking to fill an order of a buyer of mine.
Who is this "buyer" who trusts someone who uses

I have been surfing threw multiples forums of people arguing over this topic.
Which forums? Please share the links!

You have no idea what you're talking about. Normally, that's okay when asking questions on the tech board, but in this case, I think you're the wrong guy for the job. If there is such a thing.
One of the prerequisites of the transaction is to ask for a Signature Message proving the other party owns their BTC Coins.
So Electrum is my best option in this case?
Are you the one signing or verifying the message?
