Sales & Payments

The Sales module is the heart of NAOS. It’s designed to be fast, intuitive, and fully functional even without an internet connection.

Cart Management

Adding Products

  • Manual Search: Type the product name or category in the top search bar.
  • Visual Selection: Tap the product icons organized by category.
  • Barcode Scanning (Retail): Use your scanner to add items instantly.

Editing Items

  1. Tap a product in the cart to:
    • Adjust the Quantity.
    • Add a Kitchen Note (e.g., “No onions”).
    • Select Modifiers (e.g., steak doneness).
  2. To remove a product, swipe left or tap the trash icon.

Customer Management

For Electronic Invoicing (DGI), it’s essential to identify the customer correctly:

  • Quick Search: Enter the customer’s ID or RUC in the customer search bar.
  • New Customer: If they don’t exist, click the + button to register them with their name and email address (for automatic invoice delivery).
  • Final Consumer: If the customer doesn’t want their details on the invoice, select the “Final Consumer” option.

Applying Discounts and Promotions

NAOS lets you apply discounts in two ways:

  1. Per-Item Discount: Tap the product in the cart and apply a percentage or fixed amount discount.
  2. Order-Wide Discount: Apply a discount to the entire order total (e.g., 25% Senior Citizen Discount or a Promotional Coupon).

Payment Process

Once the order is ready, press the “Pay” button:

Payment Methods

  • Cash: The system will suggest common bill denominations and automatically calculate change.
  • Card (Clave/VISA/MC): Enter the receipt number from the physical card terminal.
  • Yappy / ACH: Scan the NAOS QR code or verify the manual transfer.
  • Split Payment: The customer can pay part in cash and the rest by card.

Completing the Sale

When you press “Complete Payment”:

  1. The system digitally signs the invoice.
  2. The order is submitted to the DGI (Aludra).
  3. The thermal receipt is printed with the QR Code.
  4. The invoice is automatically emailed to the customer.

Offline Sales (No Internet)

If you lose your connection, NAOS keeps working normally:

  • You can continue making sales and collecting payments.
  • Invoices are stored locally with a “Pending” status.
  • As soon as the connection is restored, the system automatically syncs all data to the cloud and submits invoices to the DGI.
