Pricing test system
How to test plans, anchors, and paywalls on real traffic without wrecking trust or billing.

How it works
01
Hold billing truth
The test can change the offer, not the ledger by accident.
- Flag the plan in the product, not in random CSS.
- Exclude existing subscribers from surprise price jumps.
02
Test the decision, not the decoration
Anchor, comparison, and default plan move more than color.
- One variable per test.
- Read revenue, not only conversion rate.
