Ask any pool supply store owner what the toughest part of the job is, and chemicals and equipment rarely come up first. It's keeping track of everything at once. Shock treatment running low, a pump part someone special-ordered three weeks ago, a regular customer who always asks about her filter warranty. A basic cash register just isn't built to hold all of that.
Add in a season that swings from dead quiet in January to a line out the door in July, and it's easy to see why so many pool stores eventually outgrow their register. What they need instead is a point-of-sale system built to keep up with the chaos, not just ring up the sale.
