Parties
Full legal names and contact details for buyer and supplier to establish contractual identity and support tax reporting.
A precise document reduces payment disputes, speeds processing by accounts payable and treasury, preserves tax and audit evidence, and helps qualify invoices for supply‑chain financing or early‑payment programs while creating an auditable record of consent and acceptance.
Teams across procurement, finance, and operations commonly prepare or review these documents before routing for signature.
Role clarity prevents duplicate processing and ensures the right approvals and bank details are on record before payment is released.
| Field | Configuration |
|---|---|
| Required fields | Make name, TIN, invoice number, date mandatory. |
| Approval order | Set sequential approval: procurement → finance → treasury. |
| Authentication | Use email link or SMS code; add KBA for high risk. |
| Retention rules | Attach automatic archival and export for accounting systems. |
Choose delivery channels and integrations that match your security, audit, and archival policies.
Ensure the chosen platform provides tamper-evident storage, an immutable audit trail, and export options that align with your retention policy.
