For our customers, we have their name, address, and telephone number.
We know exactly how many cuttings, and additional work they requested like hedges, aerating etc from the previous years.
We know exactly how much they spent with us from year to year, and our goal is to increase their spending each year.
IF we can find out their birthdays, we add that to their info, and send them a card for their birthday.
We keep things as simple as possible while still making money.
