12. Approval Process

The approval workflow for invoices is governed by a State Machine Contexts that defines how an invoice can move between states, and which user roles are allowed to perform each transition.

In this example the initial state for all invoices is Worksheet.

The table below summarizes all transitions configured for this process (as an example).

12.1 Workflow Overview

An invoice progresses through the following lifecycle states:

  1. Worksheet → Draft invoice being prepared

  2. Submitted → Invoice sent for validation

  3. Validated → Invoice verified by financial team

  4. Approved → Invoice approved for processing/payment

  5. Closed → Invoice finalized

  6. Canceled → Invoice invalidated or withdrawn

Transitions between these states are controlled by allowed actors (e.g.: Auditor, Financial)


13. Recommendations

  • Always verify currency and document type before saving.
  • Use meaningful item descriptions for audit clarity.
  • Attach the supplier’s original invoice for compliance.
  • Ensure cost centers and projects are correctly assigned for accurate reporting.
  • Monitor due dates to support timely financial processing.

14. Summary

The Invoicing module centralizes the lifecycle of financial documents, from registration to approval.
It provides a structured flow, extensive financial detail fields, item-level tracking, and full documentation support — ensuring compliance, traceability, and operational accuracy.
