"We" as in the company. It's appropriate and common usage of the word, even if there's just one person at the company. Unfortunately, Jack blows up the professional image of the Facebook page by inserting himself into it ("My wife's new Facebook page!"), using horrifyingly bright stock images, and having an unprofessional name.
As I mentioned earlier, Tam-Tam not a registered CPA. I just did a corporate name search, and "Give Me Books" is also not a registered corporation in the state of Tennessee. This is a very bad look for America's next top accounting firm.
The corporate information for Jack's other businesses included his home address.
You can take a tour of the Scooty Shack here.
Interestingly, the name for GiveMe Foods was listed as expired/inactive just over a year ago.
