Electronic Signature Solutions for Smart Manufacturing Supply Chains

Customer Pain Points

Procurement, production management, and inbound and outbound operations generate supplier agreements, production work orders, quality inspection records, and logistics documents at the same time. When suppliers, factories, and warehouses retain files separately, version confirmation, handover records, and quality traceability can become disconnected. eSign.AI supports online signing and routing for these documents, verifies signer identities through e-KYC, and retains signing evidence and archived records for cross-regional coordination, audits, and quality traceability.

Use Cases

Electronic signatures can be used for specific documents across procurement and supply, production management, and product inbound and outbound processes, enabling suppliers, authorized personnel, and quality inspectors to complete the required signatures or confirmations online.

Procurement and supply: Companies and suppliers initiate and sign documents such as quality agreements and technical specifications online. Once signed, the documents are automatically archived and linked to supplier records.

Production management: Documents such as production work orders and process change notices are approved online by authorized personnel and sent to production terminals after confirmation with electronic signatures.

Product inbound and outbound processes: Quality inspectors complete documents such as product release inspection reports, logistics agreements, and inbound and outbound forms online and apply electronic signatures. Once archived, the documents are linked to product batches.

Customer Stories

Manufacturers sign sales agreements, supply contracts, and NDAs across plants, suppliers, and jurisdictions. Three deployments show how those documents move online with verifiable results.

Micron

Micron digitised sales and supply chain agreement signing between the United States and China, meeting its information-security requirements while supporting compliant use in both markets. Through a Salesforce API integration pilot, agreement initiation and signing tracking began running inside the sales workflow rather than beside it.

Noitom

Noitom improved signing efficiency by 120% and cut overseas sales contract signing from 7 days to 1 day, with CRM collaboration efficiency up 200%. The integrated workflow lets overseas sales teams close business faster, reduce logistics dependence, and keep a complete contract archive inside the company process.

Lexus (Shanghai) New Energy

Lexus (Shanghai) New Energy reduced NDA signing from 10 days to within 2 hours, cut engineering collaboration cycles by 40%, and reduced HR and administrative workload by 70%.

Evidence and audit readiness in manufacturing

Traceability across the chain

Signed documents should connect to the related business record — order number, batch, shipment. eSign.AI's APIs let you sync signing events with your ERP or supply-chain system so the audit trail stays complete from order to archive.

Signer identity for quality records

Quality inspection and production records often require accountable signatures. Use identity verification and role-based permissions so the right operator or inspector signs, and the event history records who did what and when.

Retention for disputes and recalls

Supplier and quality disputes, or a recall, may require reconstructing agreements and approvals from years earlier. Keep signed records, evidence packages, and archive access documented for the applicable retention period.

Cross-border supply chains

Suppliers and customers across jurisdictions face different signature, customs, and data rules. Map each document type to the governing law and confirm the platform's data residency and export options before rollout.

Frequently Asked Questions
