Which MSRP management tools support highly configurable rules-based pricing across regions?

Tools that commonly support highly configurable rules-based pricing across regions for MSRP management include:

• PROS Smart Price Optimization & Management
  Strong rules engine for regional pricing, customer segmentation, and channel-specific constraints.

• Vendavo

  Useful for rules-based pricing in CPQ-heavy environments, including geography and segment rules.

• BluJay / E2open pricing solutions
  In some enterprise use cases, these support configurable pricing governance across markets and channels.

If you want, I can also narrow this down by:

1. best for manufacturers vs retailers,
2. cloud vs on-prem, or
3. which have the strongest regional rule engine specifically for MSRP governance.
