How to Share Equipment Documentation Between Companies

When multiple companies work together on a project or share equipment, the question of documentation access becomes critical. Who can see which certificates? How do you share without losing control? And what happens when the collaboration ends?

The Challenge of Cross-Company Documentation

In industries like construction, energy, and shipping, equipment frequently crosses company boundaries. A crane hired from one company operates on another company site. A subcontractor brings their own tools but needs to prove they are certified. A supplier delivers equipment with certificates that the buyer needs to retain.

Traditional approaches to sharing this documentation — email, USB drives, paper copies — create problems:

Version control — Which copy is current? If a certificate is renewed, does every party have the updated version?

Access management — Once you email a certificate, you cannot revoke access. The recipient has the file forever.

Audit trail — There is no record of who accessed which document and when.

Administrative burden — Every sharing request requires manual effort to locate, copy, and send the right documents.

Principles of Effective Equipment Sharing

1. Share Access, Not Copies

Instead of sending copies of certificates, grant access to the originals. This ensures everyone always sees the current version, and you can revoke access when the collaboration ends.

2. Use Permission Levels

Not every partner needs the same access. Some should only view certificates, while others may need to upload or update documentation. A good sharing system supports different permission levels.

3. Set Expiration Dates

Project-based collaborations have end dates. Your sharing permissions should too. Automatically revoking access when a project ends prevents unnecessary ongoing exposure of your documentation.

4. Maintain an Audit Trail

Know who accessed what and when. This is essential for compliance and for resolving disputes about documentation access.

How Certware Handles Cross-Company Sharing

Certware was built with multi-company collaboration at its core. You can share individual products or entire folders with other companies, set read or write permissions, and configure automatic expiration dates. When sharing ends, access is revoked cleanly — no stray copies floating around in email inboxes.

For permanent equipment handoffs, Certware also supports full ownership transfers, moving both the product record and its certificates from one company to another with a complete audit trail.
