I am EXTREMELY low income private practice and OON. I take check, Stripe, and Square. My payments are always noted before I even finish adding a progress note. SP has OVER calculated my income by nearly $1700. One of the individuals on my SP Tax Statement is Johnny Appleseed! I never entered any income from that imaginary client, have no idea how or why that occurred. In any case, I know now--I cannot trust SP income tax statements. It's just NOT that "simple" after all.
