Invoicing: Feature Acceptance Suite
What the Feature Must Do as a Whole
Staff can prepare billing, make an eligible correction and deliver the resulting customer document. Acceptance follows the same bill through those actions so the displayed charges and retained financial history stay connected.
Interactions Between Capabilities
Amendment changes what later rendering and delivery must contain. Posting changes the corrections staff can perform, while reading alone grants neither correction nor sending.
Regression Record
Revision one establishes the initial cumulative suite. Later changes revisit dependent scenarios, and retired scenarios retain their identities and reasons.
