I always find it fun when people say it is business expense and you can write it off
Have to make money to write it off 😉
When I had my company at the end , closed it about a year ago, everything was mostly done by email , text "
A company would send me drawing, I would email a quote , get the PO , good out do the job, email report and invoice , and receive e-transfer , if there was no problems I wouldn’t talk to anyone 😉
