Ask most owners how to grow profit and you'll hear about more customers, more sales, more volume.
In 1992, a Harvard Business Review study of more than 2,400 companies found something less obvious. On average, a 1% improvement in price, with no loss of volume, lifted operating profit by about 11%. A 1% increase in volume lifted it by about 3%.
The reason is simple. When you sell more, you also buy more materials, use more time and fill more capacity. When you charge a little more for the same work, almost all of it is profit.
Your numbers won't match those averages, and a price rise handled badly can cost you customers. But the shape holds for most businesses: price is one of the strongest levers you have, and usually the least examined.
Prices tend to be set once, when the business was smaller and keener to win work. Then they drift. A discount for one big customer that nobody revisited. Extras that used to be charged for and now aren't. Small jobs priced like big ones.
None of these feel like pricing decisions. Each one is.
Pick one product, service or customer this week and ask when its price was last properly looked at. Not increased, just looked at.
