Overview

Quantity discount rules let you offer volume-based pricing — the more a customer buys, the bigger the discount. Appify CPO supports two modes: 1D (Simple), where discounts depend only on quantity, and 2D (Advanced), where discounts depend on quantity plus a second numeric value like width or area. You configure quantity discount rules in Calculator Editor → Options & Pricing → Quantity Discount Rules. Click Configure to open the settings modal.

Steps

Setting up 1D (Simple) rules

1. In the configuration modal, set Mode to Simple (1D).
2. Choose an Aggregation mode (see Details below).
3. Set Enabled to Enabled.
4. Click Add new range to create your first tier.
5. For each tier, enter a Min quantity, choose a Discount type, and enter a Value.
6. Add as many tiers as needed. Each tier's min quantity must be higher than the previous one.
7. Click Save.

Importing tiers from a table

If you already have the discounts in a spreadsheet, you do not need to type each tier.

1. In the configuration modal, click Import table.
2. Copy the cells from Excel or Google Sheets and paste them into the import box.
3. Choose the Discount type (percent off, amount off, or target unit price).
4. For a simple list, use two columns (min quantity, discount) or two rows (quantity breaks across the top, discounts underneath).
5. For a 2D table, put axis values (area, width, and so on) on one side and quantity breaks on the other. If your sheet is flipped, set Which side is quantity?
6. Use numbers in the axis column — for example 4 for area, not a label like 2×2.
7. Review the preview and click Import. This replaces the current tiers or brackets. You can still edit them before you save.

Editing as a table

Use Table (next to Form) when you want to see or change every discount in one grid.

1. In the configuration modal, click Table.
2. For 1D, each row is a min quantity, discount type, and value.
3. For 2D, rows are axis brackets (min / max) and columns are quantity breaks. Edit a cell to change that discount. Leave a cell blank for no discount at that quantity.
4. Copy a block from Excel or Google Sheets and paste into a cell — values fill across columns and down rows from that cell.
5. Click Copy table to copy the whole grid (headers, axis ranges, and discounts) so you can paste it into a spreadsheet or another calculator.
6. Add a row or a quantity column as needed. Click Form anytime — both views edit the same rules.

Setting up 2D (Advanced) rules

1. In the configuration modal, set Mode to Advanced (2D).
2. Choose an Aggregation mode.
3. Select an Axis source — a numeric option or computed variable that serves as the second dimension (e.g., width, area, weight).
4. If the axis source is a Dimensions option, select which Dimension property to use (dim1, dim2, etc.).
5. Click Add bracket to create your first axis bracket. Enter a Min and/or Max value for the axis range this bracket covers. Or click Import table to paste a full axis × quantity spreadsheet.
6. Within each bracket, click Add new range to add quantity tiers. Each bracket has its own independent set of tiers.
7. Add more brackets as needed for different axis ranges. Brackets must not overlap.
8. Set Enabled to Enabled and click Save.

Aggregation

Aggregation controls how quantities from multiple cart lines are combined when determining which tier applies.

Discount Types

Each tier (in both 1D and 2D mode) supports three discount types:

1D Tier Settings

Each 1D tier has three fields:

The highest matching tier is applied — if a customer orders 60 units and you have tiers at 10 and 50, the 50-unit tier is used.

2D Axis and Brackets

In 2D mode, you define an axis and one or more brackets:

• Axis source — The numeric option or computed variable used as the second dimension. Only numeric option types (number, slider, length, area, volume, weight, dimensions) and computed variables are available. The Quantity option type is excluded since quantity is already the first dimension.
• Dimension property — If the axis source is a Dimensions option, you must select which sub-dimension (dim1, dim2, etc.) to use.
• Brackets — Each bracket defines a range on the axis using a Min and Max value. Leave Min blank for no lower bound, or Max blank for no upper bound. Brackets must not overlap, but they can touch (e.g., one bracket ending at 48 and the next starting at 48).
• Tiers within brackets — Each bracket contains its own set of quantity tiers, configured the same way as 1D tiers. Different brackets can have different discount amounts for the same quantity range.
• Import table — Paste a spreadsheet instead of typing each bracket. Axis cells must be numbers (the real area or width), not labels like 2×2. You can flip which side of the table is quantity if your sheet is the other way around. Imported axis numbers become contiguous ranges — either from each value to the next, or up to each value.

How Discounts Are Applied

• Discounts are applied automatically at checkout as line item discounts — no discount codes are needed.
• Quantity discounts apply to the product price only. Fixed fees are not discounted.
• The discount is visible in the price summary if the Quantity Discount field is enabled in your Price Summary settings.
• You can display a quantity tiers table on your product page by adding the Appify CPO Quantity Tiers theme block or enabling it in the Appify CPO Calculator block settings.

Examples

• Simple volume discount (1D) — You sell custom stickers. Mode: Simple. Aggregation: Per line. Tiers: 25+ units → 5% off, 100+ units → 15% off, 500+ units → 25% off. A customer ordering 200 stickers receives 15% off automatically at checkout.
• Size-dependent pricing (2D) — You sell custom metal signs in various widths. Mode: Advanced. Axis: Width (number input). Bracket 1: Width 0–24 inches with tiers 10+ → 10% off, 50+ → 20% off. Bracket 2: Width 24–48 inches with tiers 10+ → 5% off, 50+ → 15% off. Wider signs get smaller discounts because material costs are higher.
• Target unit pricing (1D) — You sell custom packaging. Mode: Simple. Tiers use "Target unit price": 100+ units → $2.50 each, 500+ units → $1.75 each, 1000+ units → $1.25 each. Instead of a percentage discount, you set the exact price per unit at each quantity break.
