ERP Integration

POs Generated and Signed from Your ERP

Connect Zignature to SAP, Oracle, NetSuite, or any ERP. When a PO is approved internally, Zignature automatically dispatches it to the vendor for acknowledgement — signed and returned automatically.

  • ERP trigger — PO approval in ERP → vendor acknowledgement sent automatically.
  • Vendor data auto-fill — Vendor name, address, and payment terms pulled from ERP.
  • Signed return — Acknowledged PO returned to ERP record on completion.

  • Long-term archival — POs retained with configurable long-term archival policies.

Frequently Asked Questions

Everything you need to know.

Are digitally signed purchase orders legally binding?

Yes. E-signed purchase orders are binding contracts under the ESIGN Act and UETA. The vendor's electronic acknowledgement constitutes acceptance, and the audit trail provides evidence of the agreement.

Can I require internal approval before sending a PO to a vendor?

Yes. Zignature's approval routing lets you configure multi-step internal approval chains — manager, department head, CFO — that must be completed before the PO is dispatched to the vendor.

How does Zignature integrate with our ERP for PO sending?

Connect via API or Zapier. When a PO is approved in your ERP, a webhook triggers Zignature to send the vendor acknowledgement request, pre-populated with PO data from the ERP.

Can vendors sign PO acknowledgements from their phones?

Yes. Vendors receive an email with a signing link and can acknowledge the PO from any smartphone browser — no account required.

How do we handle PO amendments requiring vendor re-acknowledgement?

Create a PO amendment template in Zignature. When a PO is amended, the amendment document is sent to the vendor referencing the original PO — vendor signs acknowledgement of the change.

Do signed POs satisfy SOX procurement control requirements?

Yes. Zignature's signed PO approval workflows, with approver identity capture and tamper-evident audit trails, satisfy SOX procurement controls requiring documented approval evidence.
