For a small gift store, a basic POS system would consist of a computer, cash drawer, barcode scanner, receipt printer and the appropriate POS software. A service organization, like a lawn care company, wouldn't need a cash drawer or a receipt printer. But they might want a laser printer for their service invoices. Again, you have the flexibility to easily customize a POS system for your particular business.
POS system not only gives you control over your transactions, it also puts a wealth of information at your finger tips. Imagine being able to compare year to date and month to date sales with just a few keystrokes. A database of your customers can be a powerful marketing tool. A POS system can also track your inventory, automatically creating order lists as needed, even adjusting quantities for seasonal demand. In short, a POS system helps you keep a constant eye on your bottom line.
