The finished experience

Every item. One clear estimate.

Customers can see how the items they choose add up to the price they are offered.

A good fit for
Print shops, wholesale orders, and services priced across multiple line items.

  1. 1

    Build the order one item at a time.

    Use a child form for each design or item, with its unit price and quantity. Keep the line items together in the parent order.

    GP Nested Forms

  2. 2

    Add up the whole order.

    Use Nested Forms merge tags to sum the child quantities and child entry totals. The discount threshold can span more than one line item.

    GP Nested Forms

  3. 3

    Apply the pricing rule.

    Use a conditional formula to take 10% off at 25 or more pieces. In this example, 40 tees at $18 produces a $720 subtotal and a $648 estimate.

  4. 4

    Make the estimate easy to understand.

    Show the subtotal, discount, and final estimate alongside the order details. Submit the request or add your payment integration when you are ready to take payment.

The calculation behind it

Nested Forms collects the items. Advanced Calculations uses their combined quantities and subtotals to apply the pricing rule.

Subtotal = sum of every item subtotal

Discount = 10% when total quantity ≥ 25

Quote = subtotal − discount

Why use Advanced Calculations for this?

Gravity Forms can multiply a rate by a quantity. This recipe combines totals across repeatable child entries and uses a conditional formula to choose an order-wide volume tier.

Does the discount apply to all pieces or only those above 25?

This example takes 10% off the whole item subtotal once the combined quantity reaches 25. Graduated pricing, where only later units receive a discount, needs a different formula.

Can the prices come from our product records?

Yes. Add Populate Anything to populate the item and price fields from your maintained catalog. Configure the authoritative prices and validate the complete calculation before using it for live orders.
