You don't need to have a SlickPay or other POS system to use Slick. Slick can record checkout transactions if clients pay by SlickPay, cash, voucher or on your other card reader. 

This means you can use Slick to check out client bills for services and retail products, assigning them correctly to stylists for commission calculations. You can apply discounts (percentage or absolute £ amount), record part cash payment, record payment by voucher, and record tips.

Slick offers free email receipts to clients which you can add your salon logo to and a link for clients to rebook next time.

Slick allows you to cash up at the end of the day, over any date range, showing you total takings, by cash, card, and voucher plus visibility on all of your online payments.

You can record petty cash and leave notes. You will also see a transaction log of every client checked out in that time period, with the ability to view every transaction receipt.
