Apply and Remove Promo Codes in POS
How promotion codes apply to POS carts, how discounts affect taxes and totals, and how to troubleshoot promo errors.
Before applying a code
Add the relevant cart items first. Topo validates a promotion code against the current cart, attached member, and POS sale context. A code that works for one product, plan, or member may not apply to another cart.
Apply a promo code
Add items to the cart.
Enter the promotion code in the Promo code field.
Select Apply.
Review the promo line, discount amount, tax, and total before charging.
Remove a promo code
When a promotion has been applied, the cart shows a promo line with a Remove action. Select Remove to delete that promotion from the cart and recalculate discounts, tax, and total.
How Topo calculates POS promotions
A promo must be active and valid for the current time.
A promo must apply to at least one sellable line in the cart.
Bundles are excluded from additional POS promotion allocation because bundle pricing already includes its package discount logic.
Non-combinable promotions are exclusive. Combinable promotions may stack when all existing promotions allow it.
Automatic promotions are re-derived after cart changes. Manually entered code promotions remain unless they stop being valid or applicable.
Tax is recomputed on the post-discount line amount.
Common promo errors
Enter a promotion code: the field was blank.
No active promotion matches the code: the code is wrong, inactive, or not available as an active POS code.
That promotion is expired or not yet active: check the promotion start and end dates.
That promotion doesn't apply to anything in this cart: add an eligible item or use a different code.
This cart already has a promo that can't be combined: remove the current promo or use a combinable code.
That promotion has reached its usage limit: the cap has already been used.
