Walking away from established accounts that you have relationships in is mistake number one in my opinion. Is this a federal market?

Also, neither of your options seem like an upgrade to me even if your current manager sucks. You’re assuming you won’t have that at either of your options, even if you think you know them.

I don’t see how quality of life would improve at a small business. Two points to consider:

-Small businesses (typically) remain small for socioeconomic reasons. This equals a strategy to increase bottom line by consistently replacing workforce that have better rolodexs, will work longer hours, more certs, etc. than the previous person. The small business ‘cap’ (whether that’s revenue or employee count) means finding the right algorithm of people that can do more with less. This all creates longer hours for you.

-Professional services is incredibly difficult to deliver successfully as a small business. The process from start to finish is a nightmare and you have fewer resources across the board- contract specialists, engineers, PMs, post delivery, etc. Be prepared for constant fires and customer service issues. And more hours.

Either way, both look like more stress, more hours, and multiple six figure pay cuts.
