CONFLICT WITH APPROVED RULE

Pricing changes break trust fast.

A trial gets extended without approval.
A discount rule disappears.
A plan limit changes quietly.
An upgrade path behaves differently than sales, product, or support expects.

The code may look fine. The business logic is what broke.

Mo checks GitHub pull requests against approved pricing rules before merge, so pricing mistakes are caught before customers, finance, or sales notice them.

What Mo can protect

01 — Trial logic
Trial logic

Catch changes to trial length, eligibility, renewal, or activation conditions.

02 — Discounts
Discounts and promos

Flag pull requests that change approved discount amounts, expiration rules, or promo eligibility.

03 — Plan limits
Plan limits and entitlements

Detect changes to seat limits, usage caps, feature access, or plan-based permissions.

04 — Billing flows
Upgrade and billing flows

Catch logic changes that affect upgrade paths, proration rules, or payment-gated access.

How teams use it

Step 01
Approve a pricing rule in Slack

Use Slack to approve a rule like "Trial must stay at 7 days" or "Basic plan users cannot access bulk export."

Step 02
Connect GitHub

Mo watches pull requests in the repository.

Step 03
Catch rule drift before merge

If the code changes pricing logic in a way that breaks the approved rule, Mo flags the pull request.

Examples of pricing rules teams enforce

Trial period must stay at 7 days for self-serve users
Annual plans get 2 months free
Basic plan cannot access advanced exports
Discounts above 25% require approval
Team plan starts at 5 seats minimum
Legacy customers keep original quota limits
Trial users cannot invite more than 3 teammates
Promo code SUMMER25 expires on August 31
Enterprise pricing is never exposed in self-serve checkout

Why GitHub review alone misses this

Pricing mistakes often do not look like bugs.
They look like ordinary code changes.

A pull request can be technically valid and still break an approved pricing rule. Reviewers may focus on code quality, tests, or implementation details. Mo checks whether the pull request still follows the approved business logic.
