Profit First is a financial management method that involves setting aside a certain percentage of revenue for profit, before paying expenses or distributing money to owners. One way to implement Profit First when expenses are high is to first prioritize and evaluate those expenses to determine if any can be reduced or eliminated.

Next, set a realistic profit percentage goal based on the remaining expenses and projected revenue. The percentage will likely be lower than if expenses were lower, but it's still important to have a goal for profit in order to improve the financial health of the business.

Another strategy is to try increase revenue, this can be done by increasing sales, price or by finding additional revenue streams.

It's important to remember that the Profit First method is a process and it may take time to adjust expenses and increase revenue to reach your profit goal. But it's helpful to take small incremental steps towards that goal, and consult a financial advisor, accountant or other professional as needed.
