This is turning into a wonderful start to the day/week/month/year!!
I sent my side job my monthly invoice. I got an email back from the owner saying to also give myself a $500 Christmas bonus. Then I got an email saying be sure to gross it up, so it's $500 net of taxes. Then I got an email saying that starting in January to start paying myself a flat $1000 a month. I bill hourly, but it's always around $700-$750 a month. So, nice raise!! Then I got a very nice email saying they would be hard to replace me, so if I ever have plans to stop, let him know lots in advance, please. I emailed back that I have NO plans whatsoever to stop this side job. It works perfect for me. That gave me a nice piece of mind that I'll have this job for quite awhile down the road (it's already been 5 years). When I started doing it I figured it might last 2-3 years and eventually, as they grew, they'd want an in-house accountant/bookkeeper. Glad this is working out on both ends, for more time to come!
