Promotions let you define discounts that the system applies automatically in the POS and New Sale when it detects that the configured products and conditions are met — without manual intervention from the salesperson.

​

4

Save

The promotion is active immediately (if it is within the date range).

​
How promotions are evaluated

When a product is added or modified in the cart, the system automatically checks all active, valid promotions:

​
Per-item promos (apply_on: unit_price)

  • All promos that apply to the product are evaluated.
  • Only the one with the highest priority is applied — they do not stack.
  • The discount is shown as promo_discount next to the product in the cart.

​
Subtotal promos (apply_on: subtotal)

  • All applicable subtotal promos stack.
  • The total discount is shown in the sale summary as a global promotion discount.

​
Combos

  • They require all the products in the conditions to be present in the cart.
  • The discount is at the order level: discount = sum of individual prices − combo_price.
  • If any product of the combo is removed from the cart, the discount disappears automatically.

​
Prices and IVA-exempt customers

New price and Combo prices are configured as final consumer prices (VAT (IVA) included) for taxable products. When the selected customer is marked as IVA-exempt (is_exent), the system automatically extracts the tax:
The system performs this calculation automatically in both the POS and New Sale. There is no need to create a separate promotion for exempt customers.

​
Example: percentage promotion

Result in the cart:
  • Product “Water 500ml” $1.50 → promo_discount $0.15 → effective price $1.35

​
Example: product combo

Result in the cart (if all 3 products are present):
  • Hamburger $5.00 + Fries $2.50 + Soda $1.50 = $9.00 regular
  • With combo → $0.01 discount applied to the total → **$8.99**

​
Priority and evaluation order

When there are several active promos, the system evaluates them in descending order of priority. For per-item promos, the first one that applies wins and the others are ignored for that product.
The same subtotal promo can be combined with per-item promos, but two “unit price” promos do not stack on the same product.

​
Manage active promotions

From the promotions list you can:
  • Activate / Deactivate with the toggle — useful for seasonal promotions.
  • Edit all fields without affecting the history of sales already processed.
  • Delete if the promotion is no longer needed.
