Swap Trigger PLUs

Swap Trigger PLUs are a feature added to Polygon POS for use in conjunction with QSO mode. They enable the POS Terminal to automatically swap out one PLU for another when certain combinations of ingredients are selected during the entry of an item.

Swap Trigger PLUs are recognised and implemented by both the POS Terminal and Web Menu Ordering (WMO) applications including app, native (Polygon Customer Ordering) and third-party providers (UberEats, Door Dash, Google etc).

When the selection of a specific combination of ingredients during the entry of a sale in QSO mode (either POS-driven or Customer-driven conversational ordering) requires a change to either the production ingredient or inventory decrementation, Swap Trigger PLUs enable one PLU to be automatically and seamlessly swapped out for another.

For example, a classic combo is programmed with a bread choice of either a bun or a wrap, and a protein choice of chicken, or vegan ‘chicken’. Production ingredients and stock links are programmed against the bread choice as a bun requires a chicken breast while a wrap needs chicken tenders. However, for the vegan ‘chicken’ protein choice the same vegan ‘chicken’ pattie is the required inventory link and production ingredient regardless of whether the customer chooses bun or wrap as the bread choice.

This means that whenever the vegan ‘chicken’ option is chosen, the programmed PLU for the bun or wrap (which has chicken breast and chicken tenders respectively as the inventory link and production ingredient) needs to be swapped out for a different bun or wrap PLU (which has a vegan ‘chicken’ pattie as the inventory link and production ingredient).

A QSO ingredient PLU is tagged as a Swap Trigger PLU and a Swap Items List is completed containing source and target PLUs.

If the Swap Trigger PLU is included in an order the system will look up the swap items list for that PLU. Any source PLU found as an ingredient in the build list will be swapped for its target PLU.
