How do you track subcontractor documents/insurance expirations in your company?

Hey everyone, I'm doing research on how construction companies manage subcontractor documentation (insurance certificates, licenses, safety compliance, contract files, expiration dates, etc).

I keep seeing comments about Excel sheets, email threads, or shared folders being used for this, and how easy it is to lose track or miss an expiration.

If you work with subcontractors, I’d really appreciate your insights:

1. How do you currently keep track of insurance, permits, licenses, expirations?
2. What’s the most frustrating part of that workflow?
3. If you could wave a magic wand — what would a perfect tool do for you?
4. What features would you NOT pay for or don't care about?

I'm not selling anything yet, just collecting real pain points to understand the problem better.
Any story, advice, or even examples (with sensitive details hidden) would be super valuable.

Thanks in advance!
