Selling is built around the SCAN BARCODE box. Press F4 to put the cursor there, scan a barcode or type a code or name, then press Enter. An exact code or barcode match is added; otherwise the first item shown is added. You can also tap an item tile; the category buttons narrow the tiles. Each scan adds one unit. Use + and − on a line to change the quantity by one and ✕ to remove it.

F3 turns on price check. In price check you scan an item to see its price and stock, and nothing is added to the cart.

How a line is worked out

The Price column is the price of one unit before VAT. For every line Zeyto works out: gross = quantity × price; discount = gross × discount %; taxable = gross − discount; VAT = taxable × the item's tax rate; line total = taxable + VAT. The receipt and the Total column show VAT-inclusive amounts.

The POS till with item tiles on the left and a cart of three lines on the right showing quantity, price, discount and total with the AED total and the Customer, Pay, Hold and Recall buttons. — The till: item tiles, the scan box, and the cart with its running total.

The POS scan box with the word sugar typed into it, narrowing the item tiles to matching products. — Scan a barcode or type part of a name in the scan box.

A discounted line4 units at AED 25.00 with a 10% discount. Gross 100.00, discount 10.00, taxable 90.00, VAT at 5% is 4.50, line total AED 94.50. If the same cart had a second line with taxable AED 50.00, the receipt would add each line: taxable 140.00, VAT 7.00, total 147.00.

Discounts at the till

Select a line and press F7, then type a percent. The Disc column shows the amount taken off.
You can also type over the Price. A user who may not change prices is refused when the price differs from the list price.
A user's Max Discount % (Settings ▸ Users & Permissions) caps what they can give. A bigger discount is refused.

The POS cart with a line selected and the Disc button in the bottom row used to give a discount at the till. — The bottom row: Disc, Note, Return, Void, Drawer, Reprint and more.

Settings ▸ POS Behaviour has a Line Control card. For Price override, Line void, Manual line discount and Receipt reprint you choose Allowed, Needs a reason or Needs manager PIN. For price override and manual discount you can also set a percent above which a manager PIN is needed whatever the choice says. Every use is written to POS Audit.

Promotions

Discount rules created in Inventory ▸ Discounts also work at the till. A strip above the cart lists the offers running now and has a box for coupon codes. A rule is eligible only when it is active and its dates, weekdays, time of day (for example a 16:00 to 18:00 happy hour), branch and customer group all match. Rule types include Percent, Amount, Coupon, quantity slab and buy-one-get-one.

The line discount is the promotion percent plus whatever the cashier typed with F7.
Rules that are combinable add their percents; otherwise the customer gets the better of the stack or the single best rule.
The server checks the same rules again when the sale is accepted, so a till cannot invent a discount.
A promotion flagged as needing approval asks for a manager's user name and POS PIN.

Promotion plus manual discountA line of AED 100.00 gets a 15% happy-hour promotion and the cashier types 5% with F7. The line discount is 20%: taxable 80.00, VAT 4.00, total AED 84.00.

The customer on a sale

The Customer is Walk-in by default. Tap it to search for a customer, or choose Create customer (name, phone, optional TRN) without leaving the sale. If Prompt for customer on sale is ticked in Settings ▸ POS Behaviour, PAY asks for the customer first. The Note button adds a note to a line, and it prints under the item on the receipt.

The POS cart with the Customer row showing Walk-in and the coupon code box above the cart. — The Customer row and the Coupon code box.
