@Wybill Welcome to the community! You could set up a text modifier, instructions below.
Use a Text Field Modifier (Best for custom input like “2025”)
1. Go to your Square Dashboard → Items → choose or create the item
2. Scroll to “Modifiers”
3. Click “Create Modifier Set”
4. Name it something like Graduation Year
5. Choose Text Field
6. Optional: Make it required so customers must enter a year
7. Save and Apply it to the item
8. Republish your Square Online website
What happens: On the product page, the customer sees a field labeled “Graduation Year” where they can type in their class year (like 2024 or 2025).
