The way to do this is to increase sales. And the growth is sales should take place without a proportionate increase in overheads. This will mean that your overheads are spread over more units sold and result in greater profits. This is because most overheads do not need to be increased with an increase in sales.
For example, accounting, rent and any other fixed costs. Fixed costs are those which do not change in proportion to sales. Fixed costs should be kept to an absolute minimum.
If your business trades an increase in sales will mean that your purchases will increase. This should enable you to negotiate lower prices from suppliers. The increased margins on sales will result in profit growth.
As your business grows there will be other benefits. If you have debt you should be able to negotiate better rates of interest on the business’s overdraft and any other new finance arrangements as you replace assets that need replacing
