Take stock and seek to understand why customers buy your products or services and why they might be decreasing their purchases now.
Take more time to review and consider your financial statements. Financial Statements will provide you with a wealth of information that will tell you how your business is performing -
this could be as simple as tracking the value of daily sales, or the cash balance, the debtors balance or the quantity of a key stock item you purchase each day, week, month.
Review current operations. Don't just do what you've always done because what you're doing now may be contributing to your problems.
You may need to engage an external professional to help you with such a review.
As a business owner you should not be blind to any new opportunities that may emerge as there are many.
