@Walter,
I had several items walking out the door doing the handwritten ticket way, I had no choice but to go with a POS system just to keep from going bankrupt.
It was not employee theft, just cashiers forgetting to charge items. I would over hear them say the total due, look at the ticket, and immediately know they were missing some items.
The day that pushed me over the edge was a large take-out order that exceeded $200.00, and I hear the cashier say it was $63.00.
I'd pull the register tape when I saw a large table with at least a dozen premium bottled drinks with them, and no charges shown on the register tape. The kitchen held fast to the "No Ticket, No Food" rules, but the cashiers were missing many items, and charging wrong prices,
Then we get into getting th3e servers/cashiers using different abbreviations, order being done wrong due to writing the kitchen could not read, I know that my POS investment paid for itself by stopping losses within a matter of weeks.
A refurb Dell from walmart, a refurb touchscreen from Newegg, a few printers, an eBay laser scanner. New cash drawers, and we were rocking out on the cheap.
Using the system is easy, if you set up the menu in an efficient manner.
And tonight, I was able to cut a few people loose early because I saw my labor cost creeping up where I do not like to see it, I knew instantly where it was at with a click of a button, no more guess work.
