Nexus vs. spreadsheets.

Where a spreadsheet is fine

For five workers and one or two active projects, a spreadsheet plus a folder of scanned PDFs is genuinely fine. You know each worker by name, you remember which cert is up next, and the office manager can pull anything an inspector asks for in a few minutes. Don't buy software you don't need.

What breaks first as you grow

• Expirations slip past. Conditional formatting tells you a row is red, but only if someone opens the sheet. Nobody opens the sheet the week the fit test lapses.
• Field workers can't write to it. The foreman in the basement can't update the cell that says "completed daily decon log." The sheet falls behind by the day.
• Two people edit the same row. Excel's last-write-wins overwrites legitimate updates. Google Sheets has the same problem in different clothes.
• The audit trail is "I think Mike updated it last Tuesday." When an inspector asks who entered a value, the sheet has no answer.
• The 30-year retention horizon. A spreadsheet that lives on someone's laptop is not a 30-year archive. OSHA 1910.1020 expects the record to exist when the worker requests it in 2055.
• Linking documents. The cert PDF lives in one Dropbox folder, the monitoring report lives in another, the daily form lives in a third. The sheet has a column with the file path, which broke the second time you reorganized the drive.

What changes with Nexus

• Expiring credentials surface on the dashboard before they lapse, not when somebody happens to open the sheet.
• Field workers update records directly from a phone; time punches and photo uploads queue when there's no signal.
• Every change has an author, a timestamp, and a record in the database.
• Documents (certs, lab reports, training cards) live with the structured data, not in a separate file system.
• Credential records are retained for the long OSHA 1910.1020 horizon, with renewal chains preserved end-to-end.
• Project compliance reports show, in one view, every gap across the active book of work.

What stays the same

You still need someone in your shop who owns the compliance program. Software doesn't replace a competent person; it makes their job manageable. We've watched shops try to use Nexus as a substitute for having a real safety lead. It doesn't work, and we'd rather tell you that up front than try to sell against your judgment.

When to switch

Honest indicators: your worker headcount has crossed 10 to 15. You're running more than three or four projects in parallel. You've missed a credential expiration in the last 12 months. You've had an inspection where finding a record took longer than producing it. You're losing a bid because a GC asked for a pre-qual packet and you couldn't assemble it in 24 hours. Any of those, it's time.
