Recurring Revenue Stack Migration (Handoff)

Recurring Revenue Stack Migration (Handoff)

1. 01

   Inventory every recurring charge the client has today before touching a single subscription record

   Pull the last 90 days of transactions from the incumbent processor and reconcile against the client's own revenue spreadsheet. Discrepancies of even 2 to 3 percent surface as angry support tickets two weeks after cutover.

2. 02

   Map each pricing model to a target platform that actually supports it

   Flat monthly retainers fit almost any processor, but usage-based and hybrid tiers narrow the field fast. Chargebee handles tiered and usage-based models natively, while Paddle absorbs global tax as Merchant of Record across 300+ markets, which removes a compliance workstream from the agency's plate.

3. 03

   Freeze new subscription creation 72 hours before the migration window

   Any signup during the cutover creates a record in the old system that never reaches the new one. Redirect checkout to a holding page and queue those leads for manual entry the morning after.

4. 04

   Export payment tokens, not card numbers, and confirm the receiving platform accepts them

   Token portability varies by gateway and is the single most common cause of failed migrations. If tokens cannot transfer, the client must notify every subscriber to re-enter payment details, and that conversation needs a script before it needs a date.

5. 05

   Recreate dunning, proration, and tax rules in the new environment and test them against real historical invoices

   Replay five past invoices per pricing tier and compare line items to the originals. A proration rule that rounds differently will quietly underbill every mid-cycle upgrade for the life of the contract.

6. 06

   Run both systems in parallel for one full billing cycle with the old platform in read-only mode

   Parallel running costs one extra month of platform fees and catches the edge cases that staging environments never reproduce. Document every mismatch in a shared log the client can see.

7. 07

   Hand the client a written runbook covering refunds, plan changes, and failed-payment escalation

   Include named owners on both sides and a 30-day support window where the agency answers billing questions at no extra charge. Retainer renewals are won or lost in this window, not in the pitch.

8. 08

   Schedule a 60-day post-migration audit of churn, failed payments, and revenue recognition

   Compare involuntary churn before and after cutover. A rise in failed payments usually means the new dunning sequence is weaker than the one it replaced, and that is fixable in an afternoon.
