Pricing Rule Checker
Catch pricing mistakes before they ship.
Mo checks GitHub pull requests against approved pricing rules before merge. Trials, discounts, plan limits, entitlements, and upgrade logic — flagged before they hit production.
Works with Slack and GitHub. No new workflow.
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
Catch changes to trial length, eligibility, renewal, or activation conditions.
02 — Discounts
Flag pull requests that change approved discount amounts, expiration rules, or promo eligibility.
03 — Plan limits
Detect changes to seat limits, usage caps, feature access, or plan-based permissions.
04 — 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.
Without Mo / With Mo
Without Mo
A pricing change ships.

With Mo
The pull request is flagged before merge.
The team fixes the pricing logic.
The approved rule stays intact.
Pricing mistake caught before release.
Built for teams that move fast
AI coding tools and faster release cycles make pricing mistakes easier to ship. Mo adds a check before merge so approved pricing rules are not lost between Slack conversations and production code.
