I agree that professional advice would also be needed here. I can draw a little on my own experiences which are not exactly comparable but may still be helpful to some extent. I handle the operations side of a national LLC and just in my short time in doing so, I have learned much, one being that expenses can creep in quickly and difficult to solve without making large, sometimes negative changes to the company itself.

I would like to know more of your situation and LLC if you are willing to share. Putting money away to handle possible future expenses is never bad, but I would not do it as a measure to temporarily boost what your payroll cannot handle now. Then you have to consider payroll tax, unemployment, workers comp, etc. Overhead will begin to skyrocket and depending on your net, which you state could be variable from this year to next, may not be able to sustain as much as you think.

Not to get off track but what I notice where most small LLC fail to consider is credit and properly building it. Building terms with vendors (if applicable), creating a line of credit however small under the LLC, etc. all can pay huge dividends a decade from now.
