AUTOMATIC CHAINING
Definition
Automatic linking is a process that automatically identifies and links identical or equivalent products from different data sources (catalogs, competitors, marketplaces, or ERP systems).
Using matching algorithms and, increasingly, artificial intelligence, it compares criteria such as the EAN code, brand, technical specifications, descriptions, and images to establish reliable matches.
In pricing, automatic price tracking is essential for accurately comparing competitors' prices, analyzing product assortments, and providing high-quality data to price optimization tools.
Why is this important to know?
- Ensure consistency across sizes: between variants of the same product (the L size is more expensive per liter than the XL size, as consumers would expect).
- Significantly reduce administrative time: a change to the pilot price is automatically applied to all 12 or 30 linked variants.
- Ensure compliance with business rules: price scale by format, consistent price difference between sizes, fixed ratio between colors of the same SKU.
Example
A household goods retailer sells laundry detergent in three sizes: 1 L, 2 L, and 5 L. The 1 L size is the base price, set at 6.90 €. The automatic pricing chain applies the following rule: 2 L = 1 L × 1.75 and 5 L = 1 L × 3.80. When the pricing system changes the 1 L price to €7.20, the 2 L price automatically changes to €12.60 and the 5 L price to €27.36. Without automatic price chaining, these three prices would have to be updated manually, with the risk of overlooking or
Reliable competitive monitoring and product matching prevent the comparison of non-equivalent products and ensure that repricing is based on verified matches at the product detail, EAN, and attribute levels.
Error in the ratios.
How to measure/use it
- Setting up automatic product linking involves four steps: identifying eligible product families (size, color, and scent variations)
- Define the pilot reference for each family,
- Write the rules for chaining (multiplicative ratio, additive deviation, more complex formula), and
- Configure the pricing engine to apply the rules with each update.
Pricing analytics tools natively support chaining and keep a record of each propagation for auditing purposes.
Mistakes to Avoid:
- Chaining without consumer logic: If the 5-liter size is cheaper per liter than the 1-liter size (as expected), this must be reflected in the ratio.
- Forgetting to review the rules: when purchase costs vary across formats, the old rule becomes obsolete.
- Chaining to a secondary driver: if the driver is not widely used, its adjustments drive only a marginal volume and distort consistency.
