Wallet / Credit Drawdown — Manages prepaid balances — credits, wallets, committed spend — and burns them down as usage arrives. Rated usage draws against the balance before anything hits an invoice, and low-balance states trigger alerts and auto top-up.
Where it sits in the lifecycle
Wallet / Credit Drawdown lives in the Consume & Meter phase
of Fulfill & Bill — the stage where you activate what was sold, meter what's used, bill it right.
In the corpus tool index this phase maps to the Meteringcategory.
