Subject: Clarification Needed: Composite Items for Beverage Costing in Loyverse

[HADCO]

Hello Loyverse Support Team,

I’m currently setting up composite items for beverage costing and want to confirm that I’m using the feature correctly.

I’ve reviewed your documentation here:
https://help.loyverse.com/help/how-create-composite-item

Based on the guide, my understanding is:

Composite items are intended to deduct ingredient inventory (e.g., liquor, mixers, garnishes) when a finished item is sold.

The cost of the composite item is derived from the costs of its component items.

Composite items themselves are not meant to represent multiple yield-based servings from a single bottle unless each serving is defined as its own inventory item.

Where I may be misunderstanding things is around drink costing and bottle yields. Specifically:

If I have a 750ml bottle of liquor, am I expected to:

Create an inventory item that represents a single pour/serving (e.g., 45ml), and

Build the composite drink from those serving-sized items?

Is there any built-in way for Loyverse to understand yields (e.g., 16–17 servings per bottle), or is the recommended approach always to convert everything to the smallest unit (per-serving inventory items)?

 

 

Are composite items intended mainly for inventory deduction accuracy, rather than detailed beverage cost analysis?

The current setup works mechanically, but I want to be sure I’m following best practice and not overcomplicating the structure due to a misunderstanding on my part.

 

Any confirmation or guidance—especially around recommended setups for bars or beverage operations—would be greatly appreciated.

Thank you for your help.

Hello!
I suggest using this method I have used to manage my liquid item. In this case, you can manage the cost of items and the stocks accurately. 

For example, I have a 700ml bottle of juice, and I want to be able to sell it into 100ml cup of juice.

In this case, by using the composite feature, you can start by creating the '700ml Bottle of Juice' as an item, just enter the name, price, and cost, and make sure to enable Track Stock. From there, you can enter the total number of bottles currently in stock in the quantity field.

For example, if you have three bottles, enter '3' to represent three individual bottles.

After saving, you can create the 2nd item to be able to manage selling the 100ml item.

For the 2nd item, activate the composite feature and add 700ml bottle as its component. 

In the quantity field, enter 0.143.

Why 0.143?: Since 100ml ÷ 700ml = 0.143 x 7 shots =1 / 1 bottle

So every time you sell 1 glass of juice, 0.143 will be deducted from the bottle stock. This means that if you sell 7 glasses of juice, it will be equivalent to 1 bottle.
