It sounds like you’re really on top of your numbers, which puts you ahead of a lot of small businesses. I think you are doing what you need to do. Cutting costs and making sure cash flow is not interrupted. The only other thing you can do is to do as much free to cheap advertising and think outside the box to drive sales during this downturn.
If you believe in your business, taking out a loan can get you through the rough patch. I’ve borrowed heavily over the 24 years I’ve owned my business to keep it afloat. It’s not ideal, and I don’t think I’ll ever have to do it again, but when you are just starting out and don’t have significant cash reserves, it can work if you are careful. Small business owners are some of the biggest gamblers. Except you are gambling on your abilities and not just luck.
I had a friend who had a successful bakery that she opened with very little business experience. She took a business course offered to existing business owners, and she learned a ton. She learned so much that she went back to her bakery and shut it down, realizing it would never provide her the lifestyle she wanted.
She was tired of putting in 60 hour weeks for not a lot of pay while her other skills got her much better paying jobs with less hours.
