Update pricing for plans

Update our existing monthly_29 plan to $35 and the annual_290 to $340, keep the same plan IDs, maintain the 14-day trial, and mark changes effective for new invoices only. Notify Priya in procurement and Aaron in engineering that proration is disabled and that upcoming invoices should not be retroactively adjusted.

Before I push price changes to our plans, make the approval easy: surface the customer segments that will face the largest increase, calculate projected churn risk at 5% and 10%, and highlight any customers on coupon codes or legacy discounts who will be affected. List friction points that would make procurement hesitate.

I changed the plan price for monthly_29 to $35 but our largest client still shows the old rate because they were on a legacy discount. I can’t find where that discount was applied. What is the likely place the legacy price is stored, which team should I call first, and how do I update their billing without breaking their contract or triggering a refund cascade?

We keep pushing price updates that require engineering and finance to manually reconcile accounts, costing hours each release. Should we move price management to a single owner, implement a versioned plan strategy, or require a change window with rollback steps? Recommend one change with how to implement it and a KPI to watch over three months.
