    or

Save your assignment.

4. How Customers Use the Customizer on Your Storefront

When visiting a product page with an assigned customizer, customers can:

  • Add text (if enabled)
  • Upload an image (if enabled)
  • Drag, resize, and position elements visually
  • Switch between sides (front, back, etc.)
  • See a real-time preview of their design

The preview continues through:

  • Cart
  • Checkout
  • Order confirmation
  • Customer account

This gives customers confidence in their design and reduces the chance of incorrect orders.

5. Viewing Customization Details in Orders

When a customer completes a purchase:

In the BigCommerce admin:

  1. Open the order
  2. View the product line item
  3. Click on the customization details

You will see:

  • The final rendered preview
  • The original uploaded images
  • All text inputs
  • Selected fonts, colors, and sides

These files are production-ready and can be used for printing, engraving, embroidery, sublimation, or manufacturing.

6. Managing Existing Customizers

You can edit any customizer from the dashboard.
Available actions include:

  • Adding or removing sides
  • Updating prices
  • Uploading new fonts or colors
  • Adjusting customization area sizes
  • Changing assigned products

All changes update instantly.

7. Best Practices

  • Upload high-quality background images for best preview results
  • Limit font choices for cleaner UX
  • Use transparent PNG backgrounds for apparel or product surfaces
  • Test each customizer on both desktop and mobile
  • Enable per-side pricing for complex products
