Flat / Percentage Price

The simplest pricing mode. A fixed dollar amount or a percentage of the base product price is added when the option is selected.

Setup

1. Open an element → Values tab (for selection types) or Pricing tab (for Switch)
2. Find the value you want to add a price to
3. Set Price type to:
   • Fixed — enter a dollar amount (e.g., 5.00 adds $5.00)
   • Percentage — enter a percentage of the base price (e.g., 10 adds 10% of the product price)
4. Save

Negative prices (discounts)

You can enter a negative fixed amount (e.g., -5.00) to apply a discount for a specific selection. Use with caution — the cart total cannot go below zero. If a discount would bring the total below zero, the cart total is capped at zero — the customer is never charged a negative amount.

Notes

• Prices appear next to the option label on the storefront: Large format (+$8.50)
• The price is also saved in BigCommerce, so it appears correctly in your order management view and in any tools connected to your store.
