You need to know where your sweet spot is

Every quarter your accounting department should do a company breakeven calculation.
If the company breakeven has increased, compare the current breakeven to the previous quarters breakeven to identify increased costs.
Eliminate unnecessary costs.
Re-evaluate suppliers.
Implement a price increase as a last resort.
Build a new next quarter projected P&L budget.
At the end of each quarter, you compare the budget to the P&L, to identify variances that you need to address.
A quarterly budgeting practice identifies your business's sweet spot, restrains your spending, and increases your profitability.
You need to do a quarterly projected cash flow budget to identify your upcoming cash outlays.
Your accounting department must have the expertise and resources to complete these tasks in a timely manner – to run your business by the numbers.
If you do not have a quarterly budget – you are running your business from your gut – instead of by the numbers.
