Preset quantities replace the standard +/- quantity input with a dropdown of fixed options. Instead of letting customers type any number, they choose from a predefined list like 500, 1000, 2500, or 5000.
This is ideal for products sold in specific lot sizes – printing supplies, raw materials, labels, or anything where only certain quantities make sense.
Setting Up Presets
Go to Rules and create or edit a rule
Enable Preset quantities
Enter your values separated by commas (e.g.,
500, 1000, 2500, 5000)Save the rule
When to Use Presets vs Range Limits
Presets – When only specific quantities are valid (e.g., you only sell in packs of 500, 1000, or 5000)
Min/max/step – When any quantity within a range works (e.g., buy between 1 and 100 in multiples of 5)
What the Customer Sees
A dropdown replaces the quantity input on the product page
The dropdown lists your preset values in order
Works across all Shopify themes – the app detects and replaces the native quantity input automatically
Presets and Inventory
If a preset value exceeds available stock, that option is automatically removed from the dropdown. For example, if you set presets of 10, 25, and 50 but only 30 units are in stock, the dropdown shows 10 and 25 only.
