Define why the group exists
Wholesale, VIP, reseller or employee groups should represent a genuine commercial rule.
Keep base price and discount logic separate
This makes it easier to understand why a customer received a particular selling price.
Control overlapping discounts
Multiple discount rules can unintentionally destroy margin if priority and combination logic are unclear.
Track group performance
Compare revenue, order frequency, discount cost and contribution by customer segment.
Review eligibility
Customers may need to enter or leave a group as their commercial relationship changes.
Connect pricing to profitability
High revenue from a heavily discounted segment is not automatically high-quality revenue.
The operating principle
Every event should remain connected to the product, contact or transaction that created it. That is what lets ERP explain a number instead of only displaying it.
