How a bill is made — and why it's always right.
The POS shows the total as you build the order, but the final bill is priced again on the server from your menu, your tax settings and the live coupon rules. Nobody can change a price from the device.
Item & size
The price comes from the menu, never from the screen. A size or variant adds its own price difference — Full is Half plus the gap you set.
Options & add-ons
Paid choices (oat milk, extra cheese) and add-ons are added to the unit price, then multiplied by the quantity.
Tax on each line
Each line gets its own tax rate — from the item, or your business and branch defaults. Prices can include tax (it's taken out) or exclude it (it's added).
Coupons & rewards
A coupon is checked live: dates, minimum and maximum order. A free reward or free-item coupon sets that one line to zero.
Total & adjustment
Subtotal + tax − discount = total. If staff change the final amount, they give a reason; tax is scaled to match and the original total stays in the history.
Payment
Cash, UPI, card or a Zeller terminal — all at once, in parts, or split equally. The order is paid, partly paid or pending; a gap of up to ₹1 from line rounding is allowed.
Receipt, stock & loyalty
Print or share the receipt. Stock is taken, the guest's visit and points are recorded, and the sale appears in your reports.

Built so money never goes missing
Priced on the server
The device sends what was ordered, not what it costs. Prices, tax and coupons are worked out again before the order is saved.
Permission to take money
Only staff allowed to take payments can record cash or UPI. Others use the card terminal or pay later.
Pay-later limits
Set the most one pay-later order may be and how many may be open per branch. A manager can approve more.
Card approval first
With Zeller, the server issues a one-time reference for the exact amount; the order is raised only once the terminal approves it.
Full history
Every order keeps who created it, every payment and every change of amount with its reason.
Offline bills
An offline sale keeps the amount actually charged. If the menu price differs when it syncs, it's flagged for review, not silently changed.
