Tip - Build a better Product and offer a better Service

Build a better Product and offer a better Service.  Better customer service
This is such an easy one - and it's free.  Smile, be polite, build relationships with your customers and respond to complaints quickly and calmly. It's that simple. But it's something big companies find impossible to do well.

Better quality/longer-lasting
A great one to fight off the price wars, because it makes a higher price justified. Plus, your smallness means you can put in that extra bit of TLC that really makes a better-quality product shine.
