I think you can indeed (via unitec modem or network) look at the accounting report, but I've never done it.
WSII have a built in
fleet feature. The standard
fleet software comes with 100 accounts. The enhanced
fleet software has 1000 accounts. You can have three different account options: a debit account with a balance on the machine that the customer may use to purchase any wash package, a discount code, or the standard account that will have a code that if the customer enters it will trigger whichever wash you program it to give. Those discount and standard codes can be figured to be good for a certain number of times.
You will lose some of the discount feature on CC sales if you install Cryptopay. Crytopay uses the
token input to buy washes and the I don't think the machine will allow
token usage in combination with a discount. It still works on cash sales.
I've had good luck with them, and they're simple enough to work on usually.
