Billing Plan Migration Agent
Executes bulk migrations of customer accounts from legacy pricing plans to new plan structures while preserving grandfathered terms and validating billing continuity.
When a company retires an old pricing plan and needs to migrate thousands of customers to a new structure, doing it manually risks breaking grandfathered discounts, mispricing accounts, and generating a wave of billing support tickets right after the migration
Finance and RevOps teams typically build one-off migration scripts under time pressure, test on a small sample, and then hope the full-scale run doesn't produce edge-case errors across accounts with unusual histories like paused subscriptions or partial credits
This agent runs the migration in a staged, reversible manner: it simulates the new billing outcome for every account against the current plan, flags any account where the new plan would meaningfully change the price beyond an allowed variance, and only executes the live migration for accounts that pass validation, holding exceptions for manual review
It also preserves any contractually protected grandfathered pricing so long-term customers aren't unintentionally repriced
The agent pulls the full list of accounts on the source plan, simulates their invoice under the destination plan's pricing rules using their actual historical usage or seat data, and compares the simulated result against current billing to calculate price variance. Accounts within the configured acceptable variance and without contractual grandfather protections are migrated automatically with the new plan applied effective the next billing cycle; accounts outside variance or with special terms are queued for manual approval. Every migration is logged with before/after billing snapshots to allow rollback if needed.
Build Migration Cohort
- Identify all accounts currently on the source legacy plan
- Pull each account's current pricing, usage, and contract terms
- Check for grandfathered pricing or special contractual protections
- Segment accounts by migration complexity and risk
Simulate New Plan Impact
- Apply the destination plan's pricing rules to each account's actual usage
- Calculate the price variance between current and simulated billing
- Flag accounts exceeding the acceptable variance threshold
- Identify accounts requiring custom handling due to contract terms
Execute Validated Migrations
- Apply the new plan to accounts within acceptable variance automatically
- Preserve grandfathered pricing terms where contractually required
- Schedule the plan change to take effect at the next billing cycle boundary
- Snapshot pre-migration billing state for rollback capability
Route Exceptions and Report
- Queue high-variance and special-terms accounts for manual approval
- Provide a side-by-side pricing comparison for each exception
- Generate a full migration summary report for finance leadership
- Monitor first post-migration invoice for anomalies
