lamjounah/billing-invoice

This is a Spring billing-invoice service: REST clients create, retrieve, search, update, and delete invoices, while invoice-control requests start a validation process and payment results can update invoice status. Invoice creation resolves customer, creditor, and point-of-sale references before persisting the invoice. The tree also shows separate creditor and point-of-sale management, plus messaging and workflow components. The README is empty; sampled sources establish the invoice and point-of-sale paths, while some listed integrations and delegates are represented only at their supported subsystem level.
