What's new

POS Returns

A complete in-store return workflow has been built out end to end.

• Return type, reason, and comment fields on the return cart.
• Cancellation confirmation dialog when discarding a return in progress.
• Ability to edit newly added return (exchange) items before confirming.
• Returns now refund the actual paid (discounted) price rather than the pre-discount price. Original and discounted prices are displayed side by side on return line items.
• POS return orders are now visible in the OMS order list.
• Online order returns are supported with payment info display, credit/payment toggle, and an optional shipping charge deduction.

Nets / Baxi Terminal

• New BaxiAgent1 (USB) integration with a dedicated terminal settings UI (USB/Ethernet toggle and live connection-status polling).
• The "Invalid operator Id" error on Nets terminals is fixed — the default operator ID is now configurable.
• Terminal settings: the raw IP-address field has been replaced with a user-friendly toggle.
• General Nets integration improvements and bug fixes.

Customer-Facing Display

• A secondary-screen customer display has been introduced.
• Opens frameless on the secondary monitor when a compatible display is connected.

Receipt Printing & PDF

• Shipments are now combined into one sales receipt with a single transaction snapshot.

X/Z Report Printing

• Z-report viewer in OMS — expanded with store and date filter, register filter, and improved PDF content (payment refunds, VAT summary on returns, closing cash, discounts, cancelled sales).
• AutoZReport scheduled task added for cashless devices.
• Z-reports now use the register name in the device list.

Cart & POS Settings

• Cart validation added — the pay button is disabled when validation errors exist.
• Cash UI is hidden on POS devices without a cash drawer.
• Disabling the cash drawer is blocked when the current period has cash transactions.
• Cash drawer toggle is mirrored into the Device Defaults section.
• New DisplayInPos setting in PaymentSettings to control payment method visibility in POS.

Goods Reception

• Items are now automatically added to the default location if one is configured.

• A new report center UI in OMS has been added.
