There are a number of things that any business can do, or at least consider, to improve its bottom line. You do not need to wait until you have had an extensive management training course to examine the following areas. By all means, get the best training you can, but in the meantime, start reviewing these key areas.
Most of your sales will come from a small number of your clients. Don’t be afraid to skew your priorities towards these bigger clients. In fact, you should even consider getting rid of customers who produce more problems than profit. A good way of redefining those relationships is to increase the prices you charge them.
Similarly look to up sell or cross sell existing clients rather than focussing all your sales efforts on new clients.
Don’t forget reciprocity or even bartering if you and a customer or supplier has something that the other wants.

Cash flow should always be a priority. Ensure that you are collecting money in the quickest, most efficient and cost effective way. Think of incentives to your customers to encourage prompt payment.
Manage poor performers effectively. If they are not contributing to the business or performing to an expected standard take steps to ensure they improve, or if necessary leave.
