Pricing rules: framework, examples and catalog automation

An implicit pricing rule that lives in one person's head is a risk. A documented rule applicable in bulk is a competitive advantage.

9 min readApril 17, 2026

Pricing rules are what transforms a vague pricing policy into a consistent catalog. Without explicit rules, every price is an ad-hoc decision: impossible to maintain, impossible to audit, impossible to delegate. With formalized rules, you can apply a pricing logic to 500 products in 3 minutes and roll back if it does not fit.

The 4 most useful types of pricing rules

Margin rule (cost x coefficient)

The simplest and most powerful. Selling price = purchase cost x margin coefficient. A coefficient of 2.5 gives a 60% gross margin. Applicable in bulk to an entire category, rounded to .99 afterwards.

Competitive positioning rule

Price = Competitor A x 0.95 (5% below the leader), or Competitor A x 1.05 (5% above to signal quality). Requires competitive monitoring, but the rule itself applies in bulk once the data is available.

Psychological rounding rule

After all other calculations, finish with rounding: .99, .95, .90, or integer depending on positioning. In bulk on 500 products with Seegea: 10 seconds.

Formalizing rules: the document 80% of e-commerce teams are missing

An undocumented pricing rule is a lost rule the moment the person who knows it leaves the company. Here is the minimum to document per product category:

  1. Target gross margin (e.g.: 35% minimum on fashion, 20% on best-sellers)
  2. Competitive positioning (e.g.: lower range, upper range, unique price)
  3. Rounding rule (e.g.: always .99 except premium range)
  4. Promo rules (e.g.: maximum -30%, reference price = price of the last 30 days)
  5. Exceptions (e.g.: exclusives are never discounted, end-of-life products can go to -50%)

Advice: start by documenting rules for your 3 to 5 most important collections. Do not aim for exhaustiveness from day one — an imperfect rule applied in bulk is better than hundreds of ad-hoc decisions.

From rule to execution: Seegea as the operational arm

A pricing rule only has value if it is executed quickly and reliably. Seegea translates your rules into concrete actions:

Pricing rules and legal compliance

Since the Omnibus directive (May 2022), strikethrough price rules must reference the lowest price of the last 30 days. If your rules automatically generate strikethrough prices, verify that they integrate this constraint. Seegea keeps 365 days of price history per product — you can always audit compliance.

Built in France between Annecy and Chantilly

Seegea was built by e-commerce practitioners who faced the same problems: rules in someone's head, inconsistent catalog prices, hours lost maintaining coherence. The result is a tool that executes rules as fast as you define them, with a complete safety net.

FAQ

A pricing policy defines objectives and principles (e.g.: position 10% below the market leader). Pricing rules are the concrete mechanisms that translate that policy into prices (e.g.: price = cost x 2.3, rounded to .99). Both are necessary, but rules are what you automate.
