Workflow spine
One path. Zero ambiguity.
Invoice lifecycle is intentionally narrow: create, verify, approve, and settle. Every transition is role-validated and recorded.
A. Super Admin creates and routes
Invoice is attached to subsidiary and site, then sent to assigned approver.
B. Site Approver approves or queries
Approver can only act on their own site queue and must provide query context.
C. Accounts Payable closes payment
Approved invoices move to payment handling with reporting and export support.
