A fast checkout should not create slow work afterward.

When the till, warehouse, payment record and shift handover live separately, every completed sale leaves another reconciliation task behind.

Scalar360 keeps the counter transaction connected from scan and tender through receipt, stock movement, return and closing cash review.

Counter operations

Fast for the queue. Complete for the business.

The register carries location rules into checkout, then leaves behind the records needed by inventory, sales and finance.

Registers

Give every counter its own operating context.

Bind the till to a warehouse, set its identity, opening float and checkout rules, then activate it for the team.

Scan & search

Move from shelf to cart without losing stock context.

Find items by barcode, SKU or name with warehouse quantity, unit, price and GST visible.

Checkout rules

Set the freedom available at each till.

Control decimal quantities, customer requirements, price overrides, discounts and server-enforced caps.

Payments

Record the complete tender mix.

Split one total across cash, card, UPI, wallet, bank or another method and calculate change.

Continuity

Hold a cart or keep selling through a network pause.

Resume device-held sales and safely sync offline checkouts through an idempotent outbox.

Shifts

Know what the drawer should contain.

Opening float, cash movements, tender totals, expected cash and counted variance meet in the closing report.

Receipts

Give every location the right receipt.

Configure header, footer, tax display and paper width, then print through the browser or local ESC/POS bridge.

Coupons & loyalty

Apply the offer without blurring the price.

Validate coupon limits, inspect customer points and redeem only what the balance and remaining sale allow.

Returns

Carry the reversal back into stock and credit.

Start from the original invoice, choose quantities, restock the register warehouse and create the credit note.

Connected records

Keep the counter inside the wider business record.

Checkout issues a numbered POS invoice, adjusts warehouse stock and retains the register, shift, cashier, tax and tender trail.

One connected checkout

Follow the sale from scan to receipt.

Move through each counter moment to see how item, discount, loyalty, payment and inventory context remain connected.

Scan

Find the item at counter speed.

Scan a barcode, enter an SKU or search by name. The result keeps the warehouse quantity, unit, selling price and GST beside the item.
  • Barcode or SKU Enter
  • Warehouse stock
  • Cached offline lookup

Scanned. Settled. Printed. Connected.

The counter keeps its context.

The counter journey

Keep every decision attached to the sale.

The register supplies the rules. The item carries stock and tax. The tender settles the total. The invoice holds the record after checkout.

Find

Bring the item into the cart.

Barcode, SKU and name lookup keep register-warehouse stock, unit, price and GST beside the result.

Shape

Apply the register's rules.

Quantity, customer, line discount and price-edit controls change by counter while important limits are checked again on the server.

Settle

Record every part of payment.

A sale can combine tender methods, retain references and calculate change before the issued invoice closes the checkout.

Retain

Let the sale carry its history.

The receipt, shift, stock movement, loyalty activity and any later return continue from the same transaction.

Cash with an explanation

Close the shift against expected cash.

Opening float, cash sales, drawer pay-ins and pay-outs establish the expected amount. Counted cash exposes the variance, with tender totals available for review.

The connected business

The counter does not work alone.

Inventory

Give every item a clear place in the business. Maintain your catalogue, review warehouse availability and inspect stock valuation alongside the sales and purchasing records that use them.

Sales & invoicing

Keep quotations, customer invoices and receivables in the same conversation. Give your sales and finance teams a shared view of what was agreed, billed and collected.

Accounting & GST

Keep journals, ledgers and financial reports connected to daily transactions. Work with Indian tax details while retaining the controls and review your accounts require.

Questions, answered

Before the first shift opens.

Can Scalar360 POS continue during a network interruption?

Yes. The terminal can search a previously cached register catalogue, queue completed sales in its local outbox, produce a provisional receipt and sync when the connection and an open server shift return. Idempotency protects a retried sale from being created twice.

Which payment methods can be recorded?

A sale can use Cash, Card, UPI, Wallet, Bank or Other, and one checkout can be split across several tender lines. Scalar360 records the tender; it does not itself process the card or UPI payment.

Does POS update inventory?

Yes. Every register is linked to a warehouse. Completing checkout issues the POS invoice and reduces stock from that warehouse; a POS return restocks returned quantities into the same register warehouse.

Can every counter have different rules?

Yes. Register settings cover the warehouse, opening float, default customer and tender, decimal quantities, customer requirement, price editing, line discounts, discount cap, receipt design, paper width, tax display and auto-printing.

Can the terminal use a thermal printer and cash drawer?

Yes. It can print through the browser or a local ESC/POS bridge. The local device settings support a test print, a manual drawer kick and an optional automatic drawer kick for cash sales. Compatibility still depends on the counter hardware and local agent setup.

How are coupons and loyalty points applied?

Coupons can be fixed or percentage based with value, date and redemption limits. Loyalty points belong to an identified customer; redemption is limited by the available balance and the amount remaining after the coupon.

What happens when an item is returned?

The cashier looks up the original invoice, chooses quantities, and processes a GST-inclusive return. Scalar360 creates the sales-return and credit-note records, restocks the warehouse, and can record a cash drawer pay-out when a shift is open.

How is a shift reconciled?

The cashier opens with a float, records cash pay-ins and pay-outs, then enters counted cash at close. The Z report compares counted cash with the expected amount derived from the float, cash sales and movements, and also shows payment totals by method.
