Billing Portability Premium

Billing Portability Premium is the practice of pricing how cheaply a client could leave your recurring revenue stack, not how cheaply you can run it. Every billing decision carries an exit cost: subscriber records, dunning history, tax filings, and grandfathered plan logic that a migration must rebuild. Agencies that install high-portability stacks (exportable subscriber data, gateway-agnostic tokens, clean invoice archives) can hand a client their billing engine intact, which makes the agency the trusted custodian rather than the toll booth. The premium shows up at renewal: clients renew the operator who can prove the exit is survivable. A Merchant-of-Record layer such as Paddle absorbs tax liability across 300+ markets, but it also concentrates records the client cannot easily carry elsewhere, so the agency should document what leaves with the client. WordPress membership builds on MemberPress or MemberMouse sit at the opposite end, where subscriber tables and content gates travel with the site.
