I think for a very small company this perhaps might be more complicated in computing terms than would be worthwhile, but as soon as you're getting to the point of many orders in a week, then it can be exceedingly useful to be able to ask the computer to tell you for example what are all the outstanding orders, what are all the overdue orders, what is the stock position bearing in mind that some stock is committed for certain orders, what orders have we got with suppliers to us which are still outstanding, and questions of this sort, can make your business much more efficient.
