Boosting your margins doesn't necessarily mean raising prices.
As soon as I mention margins, almost all business owners and managers turn their attention to pricing. Some are uncomfortable examining their margins and others may protest, "I can't raise my prices any higher, I'll lose business." And there are always a few who think they know what their margins are but couldn't demonstrate what they really are - and may be afraid to look too closely.
We all know that the margin we enjoy from sales in our business is what is left from the price we charge for our service and repair work after we subtract our costs. Naturally, prices directly affect margins. However, the other end of the calculation - costs - is also a critical part of the discussion. Often, I see business owners assume the costs are fixed and cannot be changed. Any consideration of increasing margins is automatically restricted to pricing decisions.
