COI spreadsheet vs. software: when should a property team switch?

A spreadsheet is not automatically a bad system. The right question is whether it still gives the team a reliable, reviewable answer without repeated manual reconstruction.

The short answer

A spreadsheet can work for a small, stable vendor list with one careful owner and simple requirements. Software becomes more useful when multiple people update the record, vendors serve several properties, requirements vary, reminders repeat, source documents live elsewhere, or managers cannot tell how a status was reached.

When a spreadsheet is enough

  • The active vendor list is small and changes infrequently.
  • One person owns collection, review routing, and renewal follow-up.
  • Requirements are consistent across the portfolio.
  • Links to source documents are stable and access-controlled.
  • The team can explain every status and exception from the record.

If those conditions hold, improve the spreadsheet before buying software: lock columns, define allowed statuses, separate evidence from approval, add an owner and next-action field, and document the operating cadence.

Signals that the spreadsheet is becoming operational debt

  • People search email or shared drives to understand a row.
  • Several copies of the tracker circulate.
  • A vendor’s requirements differ by property or work scope.
  • Expired items are found after the work has already been scheduled.
  • Reminders continue after the vendor has responded.
  • Status colors mean different things to different people.
  • Managers cannot see who reviewed an exception or when.

Use a switch threshold the team can observe

Do not switch because of an arbitrary vendor count. Switch when the cost of reconstructing status, coordinating owners, and correcting missed follow-up becomes greater than the cost of maintaining a system. Track hours spent chasing documents, duplicate outreach, late discoveries, status disputes, and management review time for four weeks. That baseline makes the decision concrete.

Questions to ask before buying

  • Can the product represent our actual requirements without declaring legal compliance?
  • Can one vendor serve several properties without duplicate records?
  • Does follow-up stop when the vendor responds?
  • Can we see source evidence, reviewer, exception, and next action?
  • How are sensitive tax and insurance files protected, retained, and deleted?
  • Can we export our records in a usable format?
  • What work remains with our team, and what work is truly automated?
