Can I release a rental Paypal invoice as a private citizen?

[Alberto C.]

Hi, i am a salaried employee, and I just rent 2 rooms in my homesteaded house in Florida just to help paying the loan. One room is vacant right now, and I was contacted by a business man from a non-american famous company, who would like to book my place, but the only way for him to do so is by using his business credit card. I dont wanna use airbnb cause I am gonna be charged 5% and he gets charged $1000 (it is a 3 month stay). I saw that i can create a Paypal invoice, that can be emailed to the custumer with a link to pay with credit card (no need for the customer to have Paypal). There is a 3% fee which is not too bad, and he can pay that he said. The question is: Can I release a rental Paypal invoice as a private citizen? Wikipedia says an invoice may contain a tax number and that "The US Defense Logistics Agency requires an employer identification number". But then I see other website that EIN is not mandatory. I am breaking any Law by releasing a Paypal invoice with no EIN and no tax number of seller, only my name and adddress? If yes, which are the risks/consequences?

Thank you
