Why

You've got 200–500 incident reports landing by email and phone, 10+ investigators heading into the field, and 1,000+ existing clients whose history matters. That's well past spreadsheet range — but the "deals" you're tracking aren't deals, they're cases moving from report → assigned → field work → report → closed. Most CRM advice assumes a sales funnel; yours is an operations queue with field handoff. The bottleneck isn't conversion, it's making sure no incident sits unassigned and every field investigator can update status from a phone.

What you actually need

1. [HubSpot Free CRM — free for unlimited users](https://www.hubspot.com/pricing/sales) — use it as a shared inbox + case record. HubSpot CRM is free forever for unlimited users. Build a custom pipeline called "Cases" with stages matching your real workflow, and connect your intake email so every report becomes a record tied to the client.
2. [Pipedrive — ~$14–15/user/mo, check current pricing](https://www.pipedrive.com/en/pricing) — if HubSpot Free feels too marketing-flavored, Pipedrive's strong mobile app lets field investigators update case status, log notes, and upload evidence photos from the scene. Worth the ~$150/mo for 10 seats only if your field updates are the pain.
3. A 60-second intake template (habit). Every phone/email report gets the same five fields captured before anything else: client, incident type, location, date/time, reporter contact. Non-negotiable. This alone will save more time than any software.

Do this today

Open HubSpot Free, go to Sales → Deals → Pipelines, rename the default pipeline to "Cases," and replace the stages with: New Report → Assigned → Field Investigation → Report Drafted → Closed. Then forward one real incident email from today into it and assign it to an investigator. 20 minutes, one person.

What to ignore

Skip HubSpot Sales Hub Professional — $100/seat plus a $1,500 onboarding fee for 10 people is roughly $13,500 in year one for sequences and forecasting features built for outbound sales reps, not PIs. Skip Salesforce Pro Suite at the same tier. And ignore vertical "legal case management" suites being pitched to PI firms — they're priced for law offices with billing/trust accounting needs you don't have.

What doing nothing costs you

At 200–500 reports a month across 10+ investigators with no shared system, incidents sit unassigned, field notes live in someone's text messages, and client status calls turn into "let me check and get back to you" — which is how PI firms lose retainer clients to the firm that answers in one ring.

Where this leaves you

A single queue every investigator can see, a client-history view when the phone rings, and zero incidents falling through the cracks between intake and the field. The contrarian beat: every salesperson will tell you that you need their paid tier because of your "1,000 clients" — your volume actually argues for the free tier first, paid only when you hit a specific wall.

When to revisit this

When two investigators show up to the same scene, or a client calls about a report you can't find within 30 seconds — that's the signal you've outgrown the free tier and need Pipedrive's mobile workflow or paid automation.
