Drink sizes (pint, half, wine measures)

Pubs sell the same drink at several sizes — a pint or a half, wine at 125/175/250ml or the bottle, spirits as single or double. A size set holds those sizes once. You put that set on a category, and every product in the category is then sold in those sizes; each product prices each size itself. The size carries no price of its own.

That is the whole shape of it: sizes belong to a category, prices belong to a product. You never put a size set on one drink at a time — a 200-line draught list would be 200 clicks.

Create a size set

1. 1

   Open Items → Sizes

   Use New size set and name it after the shelf it prices — Draught, Wine, Spirits.

2. 2

   Add the sizes

   Add the normal size first (Pint), then the others (Half). The default is the size a bare tap on the till rings — its price becomes the product's normal price.

3. 3

   Set the stock multiplier

   "Stock" is how much stock the size uses, where the normal size = 1 — a half pint is 0.5, a double spirit is 2. The default is always exactly 1.

Put the sizes on a category

This works from either end — from the category, or from the size set itself.

From the category:

1. 1

   Open Items → Categories and pick the category

   Beers, Draught, House Wine — whichever category holds the drinks that share these measures.

2. 2

   Choose the size set under Sizes

   Every product in the category is now sold in those sizes, and each one's normal size starts at the price it already had — nothing changes on the till until you say so. Choose No sizes to take them off again.

From the size set — quicker when one set covers several categories:

1. 1

   Open Items → Sizes and pick the set

   The set's page lists every category under Categories with these sizes.

2. 2

   Tick one or more categories, then Save

   Nothing changes until you press Save at the top — so you can tick several categories and apply them in one go. A category already using a different set says so on its row; ticking it moves it to this set, and its old set's prices for those drinks are deleted (the page spells this out before you save). Unticking a category takes the sizes off it — its drinks go back to selling at their normal price only.

3. 3

   Press “Price products in this set”

   The button on the same page takes you straight to the pricing grid for everything you just attached.

Price a whole shelf at once

Open Prices on a set (or the Price products in this set button in its editor). Every product in the categories using that set is a row, every size is a column, and one Save applies the whole grid.

• Blank = not sold in that size. Prosecco can be bottle-only: leave the other cells empty.
• The last column ticks itself when a drink currently sells in no other size. It is named after your normal measure — Only Pint, Only 175ml. Tick it to clear that drink's other sizes in one go; type a price into any other size to untick it.
• The default column can't be blank or £0.00 — it is the product's normal price.
• To add or remove a product from this grid, change its category. The grid shows which categories feed it, at the top. A product moved out keeps its saved size prices, so moving it back restores everything.

What it changes on the product page

A product in a category with sizes shows a Sizes card. It names the category the sizes came from, and takes one price per size. Its base price becomes read-only — it mirrors the default size's price — and per-menu price overrides are switched off for that product, because its prices now come from the size grid.

The card has no size-set picker: sizes come from the category, so that is where you change them. Taking the set off the category makes the base price editable again on every product in it, starting at the default size's price.

Where staff pick a size

There are two ways for staff to pick a size on the till, and you choose which:

• In the pop-up: tapping the drink opens a window with the sizes in it — Pint, Half — each with its price, just like a modifier.
• Buttons at the bottom: staff tap the size first (Half, Double, the wine measures), then tap the drink.

It is one or the other, never both — if the sizes are in the pop-up, the buttons are hidden. Either way it only affects drinks that come in two or more priced sizes.

You set it per size set

Each size set says how its own drinks are rung. It is on the Sizes page, in the Picking a size column of the table, on each set's own row:

• In the pop-up — tapping the drink opens a window with the sizes in it.
• Buttons at the bottom — staff tap the size first, then the drink.

It saves as soon as you choose. Because a size set is what you put on a category, choosing here covers every category using that set — set it once for Draught and every beer shelf follows.

There is no venue-wide setting: Wine can open a pop-up while Draught stays on the buttons, and nothing above the table overrides either. New size sets start on In the pop-up.

Payment terminals always use the pop-up. They have no size buttons, so this setting does not apply to them — that is the only way they can sell a half. Online ordering and click & collect always sell the default size.

Devices pick up any of these changes on their next check-in, usually within a minute — nothing needs reinstalling.

Frequently asked

Can a product be in two size sets? No — one set per product, and that is worth watching, because a product can be in two categories. If those two categories have different size sets, the drink has two possible normal prices and the cheaper one is what shows on receipts, online orders and reports. The portal won't let you create that, and warns you in red on the category and the product if it already exists. Fix it by putting the product in one of those categories only, or by giving both categories the same size set.

I put sizes on a category and other drinks got sizes too. That's how it works — the set applies to everything in the category. That is usually fine: a drink is only actually sold in a size once it has a price for that size, so tick Only Pint (or leave the other cells blank) for the ones that come in one measure only. Move a drink to its own category only if it shouldn't be sized at all.

Do sizes show on the till? Yes — either in a pop-up when staff tap the drink, or as buttons beside the category list where staff press the size first, then the drink. A plain tap always rings your normal measure. You choose which, per size set — see Where staff pick a size above.

What happens if staff pick a size a drink isn't sold in? The till rings nothing and says which sizes it does come in — for example "Guinness 0.0 doesn't come in Half pint — only Pint." The size is unselected at the same time, so the next drink tapped rings at its normal measure; staff press the size again if the next one was also meant to be a half. See Ringing up items with options.

Set up a lot of drinks at once

Pricing a whole bar one product at a time is slow. Two shortcuts:

Import a price list

If your prices are in a spreadsheet, the CSV importer can create the products, the size set and every per-size price in one go. Add a Size Set Name column and one Size Price: column per measure — mark the standard one with a *, e.g. Size Price: Pint*. One drink can span several rows, one measure each, which is how most pub lists are already written.

The importer puts the size set on the category each product lands in, so give your sized drinks a Category Name — a row with no category is priced but not sized, and the import tells you which ones. And because a category holds one set, all the drinks in a category must name the same size set: a file that puts Draught and Wine drinks in one category is refused, naming it.

Convert a modifier group you already use

If you have been faking sizes with a modifier group — a "Size" group with Small / Large priced as an extra — you don't have to redo it by hand. Open Items → Sizes and choose Convert a modifier group, or click Convert to sizes straight from that group's own page under Items → Modifiers — it opens the converter with the group already picked.

1. 1

   Pick the group

   Only groups that are really sizes. Milk, extras and cooking preference should stay modifier groups.

2. 2

   Check the mapping

   Each option becomes a size, and each product's price for it is its base price plus that option's extra — shown in full before you commit. Choose which measure is the standard one, and say how much stock each of the others takes out (a half is 0.5). We won't guess that: getting it wrong would quietly drain your stock at the wrong rate.

3. 3

   Check what else gets sizes

   Sizes go on the category, so any other product in the same categories is sold by size too. They're listed by name before you convert, and they keep their current price, sold in the standard size only — nothing is re-priced. Tick to confirm, or move one to a different category first.

4. 4

   Convert

   The size set is created and put on those categories, the products are priced, and the modifier group is taken off the ones you ticked. The group itself is not deleted — it stays under Items → Modifiers if you want it elsewhere.

Made a mistake? Undo on the next screen puts the modifier group straight back and takes the sizes off those categories. Converting again re-creates the prices from the modifier group, so the round trip lands where it started.

Products already in a category with sizes are skipped, and so is anything whose standard-measure price would come out at £0.00 — both are listed before you convert.

Or just ask the assistant

The same conversion can be done by asking, if you have the menu Assistant: "change all my spirits to have the single/double size rather than the modifier single/double, and all the prices now are for a single — the doubles are 70% more". It asks you which measure is your normal price and names the other products in those sections, then shows you the same full table before you approve. That route can also re-price as it converts — a percentage on the bigger measure — which this screen does not do; here each size is always the product's price plus that option's existing extra. See Change your menu by asking.

Two things the Assistant route does that save a busy bar real time. If several products each carry their own size-like modifier group — eighteen spirits, eighteen "Single/Double" groups — one ask converts all of them into one size set with one approval, not eighteen. And if your drinks are already sold by size, it knows: ask it to "make the doubles 70% more" and it re-prices the size across the whole set in one approval, showing today's price and the new one for every product — it will never try to rebuild sizes you already have.
