I might be asking an even more basic question than that - How would it simplify my expenses to open a business account? Is that purely for transaction tracking, or is there some tax form I’ll get at the end of the year that simplifies filing?

I currently have a checking account that is only used for business purposes, but it is a personal account (as opposed to a “business checking account” from my bank, which has more fees and balance/activity requirements). I’m asking if there are any concerns with doing that in this situation.
