Invoicing

Planned service

Invoicing is documented in advance to support architecture and operational planning. It is not available as a deployable service or API contract yet.

Invoicing will create and manage billing documents from finalized commerce activity. It is intended to keep document generation separate from checkout execution and payment-provider mechanics.

Capability	Intended behavior
Invoice generation	Build invoice documents from completed orders and billing data
Tax and currency context	Preserve the pricing, currency, and tax information used for the transaction
Lifecycle records	Track draft, issued, voided, and settled document states
Delivery integration	Hand documents to the Notifications service or your delivery channel
Retention	Support a durable, auditable document history

Integration boundary

Commerce services will provide a completed-order or billing event; Invoicing will own the resulting document lifecycle. Product services should not write directly to its data store.
