Product Builder Pricing and Bulk Discounts

Product Builder pricing controls how customer selections change the final product price and how larger configured orders qualify for bulk discounts.

Price display mode

  • Purpose: Controls how an option’s price contribution is shown next to the option label.
  • Options: Differential or Absolute.
  • Recommended: Differential when most options are small add-ons. Absolute when the configured product feels like a different SKU at each step (e.g. selecting a size that fully replaces the base price).
  • Example: A $100 base product with a +$10 option renders as +$10 in Differential mode and as $110 in Absolute mode.

Option pricing types

Each option’s pricing has a type and a value.

  • None: the option does not change the price.
  • Fixed: adds a fixed monetary amount (can be negative).
  • Percentage: adds a percentage of the base product price.
  • Formula: evaluates a token-based formula. Use for inputs whose price depends on other selections.
  • Linked product: uses the price of a linked WooCommerce product (also drives stock checks — see Linked Products and Stock).

Formula syntax

  • Placeholders: {base} = product price, {qty} = cart quantity, {option:group_id} = numeric value of another group’s selection.
  • Operators: +, -, *, /, parentheses.
  • Example: {base} * 0.1 + 25 adds 10% of the base price plus $25 flat.

The parser is token-based (no eval()) and ignores unknown tokens for safety.

Option modifiers

  • Purpose: Apply a secondary adjustment to an option’s calculated price. Most useful with Linked product pricing.
  • Options: None, Fixed or Percentage.
  • Example: A linked-product option priced at $40 with a 10% modifier resolves to $44. Use modifiers when the same linked product needs slightly different pricing in different builds.

Bulk discounts

  • Enable bulk discount: turns tier-based discounts on.
  • Count mode:
    • Options: count the number of selected options across the build.
    • Quantity: count the quantity values entered in quantity fields.
  • Tiers: a list of min_qty + discount_percent pairs. The highest tier whose min_qty is reached wins.
  • Upsell nudge: when the cart is below the next tier, the breakdown shows how many more items unlock the next discount.

Example tier list:

Bulk discount tiers 
min_qty=5,  discount_percent=5
min_qty=10, discount_percent=10
min_qty=25, discount_percent=15

With this configuration and Count mode set to Options, a cart with 12 selected options gets a 10% discount because 12 is at or above the 10-item tier but below the 25-item tier.

Testing checklist

  • A configured product with one of each pricing type (Fixed, Percentage, Formula, Linked).
  • A second configured product with an Option modifier applied.
  • A cart that crosses each bulk discount tier boundary, including the highest tier.
  • A cart quantity change to confirm Count mode counts the right thing.
