Yes, I still have some stragglers from last year that haven't paid me, I didnt aggressively collect during the first -6-7 months of the pandemic, then I got lazier as the holidays rolled around. 

Theyre all good for it, I know they'll be back, but dang it, I hate having to open each return to print the invoice!

Yea yea yea get paid up front I know!  😁
