Quantity-based surcharges in Custom Products
Current Situation / Problem:
Custom Products allow merchants to offer additional services or configurations (e.g. sawing, drilling, processing) with fixed surcharges per selected option.
These surcharges are currently static and independent of the ordered quantity of the main product.
While tiered pricing can be configured on the product level, it cannot be applied to Custom Product options or their surcharges.
Concrete Use Case
A merchant sells steel beams (e.g. HEB / HEA) and offers optional processing services via Custom Products.
Example: Option “Sawing”
- Sub-options: Fixed cut, Center cut, Mitre cut
- Current behavior: fixed surcharge, e.g. €15 per cut
Desired behavior:
The price per cut should change depending on the ordered quantity of the main product, for example:
- 1–3 items → €15 per cut
- 4–10 items → €10 per cut
- 11+ items → €7 per cut
The price tier is not based on the number of selected options, but on the product quantity in the cart.
Why Existing Features Are Not Sufficient:
- Advanced pricing on the product level applies globally to the product quantity, but does not affect Custom Product surcharges
- Rule-based surcharges can be enabled or disabled, but do not support tiered pricing
- Product variants are not a viable alternative because:
- They would result in a very large number of variants
- Custom Products are intentionally used for flexible, customer-specific configurations
Business Value / Benefits:
Relevant use case for:
- Metal processing
- Cutting and machining services
- Printing, engraving, personalization
Key benefits:
- Realistic representation of volume-based discounts for services
- Reduction of manual pricing agreements and individual offers
- Increased competitiveness for B2B shops
Avoidance of workarounds or external pricing logic

Another conceivable scenario:
"The effort required for one piece is much higher than for five pieces, for example. Is it possible to configure the custom product so that the engraving option (file upload) costs CHF 20 for the first piece and only CHF 12.90 for five or more pieces, for example?"
