Anyone here have experience with financial forecasting for small businesses?

You're definitely right, planning is key! I've found that just winging it can lead to some stressful situations down the line. If you're looking for some structure, I've heard good things about getting some interim financial management help. It sounds like they could really help you get your ducks in a row, especially with the growth you're experiencing. From what I understand, they can provide strategic planning which would be super beneficial for understanding your cash flow and making sure your pricing aligns with your costs before expanding that menu.
