I am doing the exact same. As I've mentioned, I got my PPP loan through a small credit union I became a new member of. I left that money in that account and moved all of the qualified expenses under the Act to pull from there directly. I don't plan on having anything else come out of there if I can, that way the account itself will be the ledger I can present for loan forgiveness. My "problem" is, I was approved for more than double what I applied for. I did not request the higher amount, however, the underwriter at the credit union said I was eligible for both the payroll side from my 940 as well as line 31 on my Schedule C because I file as a sole proprietor. Obviously, wonderful news in terms of getting additional money at this time, but I will not burn through that full amount on just payroll rent and utilities alone. Worst case, I'll end up getting a substantial loan at 1% interest which is a good thing itself, but I'm going to spend some time over these next few weeks figuring out potential ways I can make as much of that figure be forgiven as possible.
I'll be sure to relay anything noteworthy I find here.
