I ran into Mark Tobias here in Rio de Janeiro. We were both attending a party to commemorate the third anniversary of the passing of a dear friend of ours, Doug Matheson. I soon found out that Mark is known as the tax man. No, he doesn’t work for the IRS, so don’t fly an airplane into his building. He is the software tax man. As our sales tax code gets continually more complex, Mark is the expert that writes the software to make sure that all the sales tax codes are being followed when we make an online transaction.
