Why keeping product documents current is so hard

Declarations, technical data sheets, manuals and certificates come from different suppliers, in different versions and with different expiry dates. They usually end up in network folders and mailboxes, and the knowledge of which version applies lives in one person's head. The problem only surfaces when a customer, distributor or inspector asks for the current document and the team is not sure whether the one in the folder is still valid.

Every document and certificate linked to a product

In DPPC, PDF documents and certificates are not kept in a separate archive. They are linked to specific products. A certificate has a number, issuer, issue date and expiry date, and one certificate can cover many products. That makes it immediately visible which products a document applies to, and which products will lose their complete evidence when a certificate is no longer valid.

Expiry dates and an automatic "expired" status

Once the expiry date passes, DPPC automatically marks the certificate as expired. A product with an expired or rejected certificate loses full readiness, and its readiness score shows the gap. Such a product cannot be approved for publication until a valid document is added. The expiry date is also visible on the public passport page, so anyone scanning the QR code can see how long the certificate is valid.

Document reviews with deadlines and reminders

Every new document and certificate goes into review with a deadline: five days by default, and two days for a certificate that expires within 30 days. If the deadline passes and the document is still waiting for a decision, the system sends an in-app reminder. The review center gathers all documents awaiting a decision in one place and lets you approve or reject them in bulk, with a note explaining the decision.

Versions, checksums and change history

A new version of a document does not silently overwrite the old one. DPPC stores each version with a SHA-256 checksum, so you can verify that a file has not been altered and restore an earlier version when needed. Product approvals, rejections and publications are added to the history, and organization owners and admins can see an activity log for the whole team. The duplicate center helps catch the same document uploaded more than once.

How to organize product documentation in DPPC

Start with the product group that has the most certificates. Import products and certificates from CSV files and add PDF documents through the import with attachments. Automatic pre-checks point out files whose names do not match, duplicates and unusual file sizes. After the review, the readiness score shows which products are missing documents or valid certificates, and those gaps are a good starting point for conversations with suppliers.

FAQ

Frequently asked questions

How does DPPC keep certificates up to date?

Every certificate has an expiry date. Once it passes, the system automatically marks the certificate as expired, and the products it covers lose full readiness and cannot be approved for publication until a valid document is added.

Can we restore an older version of a document?

Yes. Every version of a document and certificate is stored together with its SHA-256 checksum, and an earlier version can be restored.

Who approves documents?

Permissions depend on the role in the organization, for example compliance manager or admin. Every decision is recorded, and a rejection can include a note for the person who uploaded the document.

What files can be added as documents?

Product documents are added as PDF files of up to 10 MB. Each document has a type, an owner, a review status and a setting that controls whether it appears on the public passport page.

Do customers see all of our documents?

No. Only documents and certificates marked as public appear on the passport page. Downloads go through links that are valid for 30 minutes and are logged.
