Is a digital approval workflow still needed when a document must be physically stamped?
Yes. A physical stamp performs the sealing act, while a digital workflow controls authorization, version, responsibility, and evidence. The useful design is one loop—online approval, controlled stamping, scanned return, and register archiving—not unrelated online and paper records.
Whether a physical stamp is legally or commercially necessary depends on the document, counterparty, company policy, and legal advice. Where sealing involves contract versions, financial authority, or accountability, a system can answer four basic audit questions: who requested it, who approved it, which file was stamped, and where the executed document is stored. It does not determine contract validity or replace legal review.

| Method | Evidence retained | Main gap | Fit |
|---|---|---|---|
| Paper circulation | Handwritten signatures and physical file | Versions are easily confused and retrieval is slow | Very low volume where policy permits |
| Chat or email consent | Messages and scattered attachments | Identity, authority, and final-version mapping are weak | Not a formal primary process |
| Digital approval plus physical stamp | Decisions, comments, file hash, custodian, and returned copy | The stamp and scan still require human checking | Preferred physical-stamp route |
| Compliant electronic signing | Identity, time, certificate, and integrity evidence | Not accepted for every document or counterparty | Use after legal confirmation |
Assign the file a unique version and lock approved content. A substantive edit creates a new version and triggers the necessary approvals again. After approval, issue a stamping task that specifies the authorized file, stamp type, number of copies, and validity period. Record the actual time, operator, exception, and returned scan, and link the request, original, final document, attachments, and underlying transaction. Restrict downloads and printing for sensitive contracts and audit exports.
Roles must be specific: requester, business owner, finance, legal, stamp custodian, and archivist. Define approval conditions by value, document type, entity, and region, together with countersignature, alternative approval, added approver, withdrawal, and delegation. An administrator should not be able to change workflow, approve on another person's behalf, and erase evidence. Apply least privilege, dual control for critical actions, and append-only or otherwise protected audit records.
Test normal approval, rejection, document replacement, absent approver, duplicate stamping, wrong stamp, expired task, and cancelled contract. Useful measures include the match between final scan and approved version, node completeness, closure of exceptions, retrieval time, overdue tasks, and whether a log reconstructs a real event. Establish the baseline from the client's present register instead of promising an invented percentage.
China's Electronic Signature Law addresses qualifying data messages and reliable electronic signatures, but counsel must assess each document and service. Shared accounts, incorrect permissions, and offline substitution can still weaken evidence. NIST's digital identity guidance is a useful technical reference for identity and authorization.
Wavesteam starts with actual contract samples and the current stamp policy. For only a few documents each month, configuring the existing OA is usually better than building a new system. A custom module is more plausible across multiple entities, stamps, regions, or integrations with contract, procurement, and finance systems.
