Item Add-ons

Some items are not sold plain. A coffee comes with choices of milk and sugar; a shirt comes in sizes and colours; a meal comes with extras. Add-ons let the cashier capture those choices when the item is added, so the order — and the kitchen ticket — is exactly what the customer asked for.

How it works at the counter

When you add an item that has add-ons configured, the add-ons dialog opens automatically. It presents the choices in tidy, titled groups, and you tap your way through before confirming the item onto the invoice.

An item can have up to ten groups of add-ons, each with its own title in the POS — "Milk", "Sugar", "Extras", "Sauce", whatever fits. For each group your business decides:

• Single or multiple choice — pick exactly one (like a size) or several (like toppings).
• Required or optional — a required group must be answered before you can confirm. Try to skip it and the dialog stops you.
• A default choice — a group can come pre-selected with the most common option, so the cashier only changes it when the customer asks for something different.
• Search and browse buttons — for groups with many options, so a long list stays manageable.

Sizes, colours and revisions

Beyond free-form groups, an item can also offer its built-in sizes, colours, and revisions (variants) as choices in the same dialog. Each can be shown by name, by code, or both, and in the order your business prefers. This is how a clothing store rings up "blue, medium" or a workshop picks the right variant of a part.

A note on free items

Add-ons are about choices on an item you are selling. They are different from free items — the "buy one, get one free" kind of promotion — which have their own behaviour around when the free line appears and how it is reconciled at payment. That is covered separately in Free items in POS.

Keep groups sensible

A few well-named groups beat a dozen crowded ones. Put the common extras first, make only the genuinely essential groups required, and turn on the search button only where a group is long enough to need it — the cashier will thank you on a busy night.
