BEST POS - Subtotal and customer display

Subtotal and Customer Display in BEST POS (Retail)

Summary

This article explains how to show the subtotal at any time during a sale without finalizing it, and how to ensure the customer display reflects amounts correctly. Steps cover discounts, taxes and fixes—no screenshots needed; labels and paths are explicit.

Step-by-step Instructions

1) Prerequisites

  • Cashier is logged in and a sale is open.
  • The customer display (if present) is connected and enabled in device settings.
  • Tax and discount rules are configured (known calculation order).

2) Show subtotal during the sale

  1. On the sales screen, press the Subtotal key.
  2. Check: the subtotal appears (pre/post-tax per settings) without closing the invoice.
  3. Press any sales key again to keep ringing items or proceed to tender.

3) Customer display: what the customer sees

  • When you press Subtotal, the amount is also sent to the customer display (if enabled).
  • If the amount does not appear: check cabling, device selection and retry the operation.
  • After a discount or price change, press Subtotal to refresh the display and confirm the calculation.

4) With discounts and taxes

  1. Apply the required discount (line or subtotal).
  2. Press Subtotal: verify the amount reflects the discount and tax calculation order.
  3. If unexpected: remove the last action (Void) or fix input (Correction/CE), then retry.

5) Finalize or continue the sale

  • To tender, follow your rules: direct payment or mandatory payment (multiple tenders allowed).
  • To keep ringing items, press the next item key or scan; subtotal will update as needed.

Tips and FAQs

  • Subtotal vs total due: subtotal is an intermediate check; total due is confirmed at tender after discounts and taxes.
  • Rounding: if decimals differ, verify currency, tax and discount rounding settings.
  • Missing key: if Subtotal is not mapped, ask your admin to add it to the keyboard/screen.
  • Inactive customer display: if nothing shows, check the port, driver and device assignment.
