Zapier connects the software your firm already uses: when something happens in one app, it does something in another, no code required. A form gets filled, the CRM record appears and the lead gets a text. A retainer gets signed, the client folder builds itself. That’s the whole product, and for most law firms it’s the single highest-return $30 a month they’ll ever spend.
My firms run hundreds of zaps. The 10 below are the ones I’d rebuild first if I started over, in the order I’d build them.
The 10 automations, in build order
1. New lead form to CRM plus instant text-back
Trigger: someone submits your website contact form. Action: create the contact in your CRM and fire an SMS within seconds (“Got your info, calling you in the next 10 minutes”). Speed to lead is the most underpriced number in legal marketing; a lead texted inside a minute converts at multiples of one called the next morning. This zap is the foundation of AI intake.
2. Missed call to SMS follow-up
Trigger: your phone system logs a missed call during business hours. Action: text the caller “Sorry we missed you, want us to call back or would you rather book a time?” with a scheduling link. Every missed call is a lead you already paid for. This zap took one of my firms 20 minutes to build and recovers signed cases every month.
3. Retainer signed to welcome sequence and task list
Trigger: the e-signature tool marks the retainer complete. Action: enroll the client in a welcome email sequence and create the standard onboarding task list in your project tool, assigned to the right person. The first 48 hours after signing set the tone for the whole case, and nobody should be building task lists by hand.
4. Settlement closed to review request
Trigger: matter status changes to settled or closed-won. Action: wait two days, then text the client a direct link to your Google review page. Reviews are the cheapest marketing a firm owns and the moment of maximum goodwill is right after the check clears. Firms that automate this collect reviews every week; firms that don’t collect them never.
5. New client to Drive folder structure
Trigger: new client record created. Action: build the standard folder tree in Google Drive (Pleadings, Correspondence, Client Docs, Billing), named to your convention. Ten seconds of compute replaces the paralegal ritual of copying last client’s folders and hoping nothing stale came along.
6. Document-collection reminder cadence
Trigger: a client is tagged “docs outstanding.” Action: send a reminder at day 3, day 7, and day 14, each with the upload link, then flag a human if nothing arrives. At my lemon law firm, chasing repair orders used to eat paralegal hours. Now the cadence runs itself and staff only touch the cases that stall.
7. Intake call logged to AI summary in Slack
Trigger: a completed intake call hits your phone system or CRM. Action: run the transcript through an AI step that pulls out claim type, damages, and a strength read, then post the summary to your intake Slack channel. Managers see every lead’s quality in real time without listening to a single recording.
8. Invoice paid to thank-you and next steps
Trigger: payment received in your billing tool. Action: send a receipt-plus-thank-you email that tells the client exactly what happens next on their matter. Clients complain about silence more than about fees. This one email, sent automatically at the moment they’ve just paid you, kills most of it.
9. Weekly KPI digest to email or Slack
Trigger: schedule, every Monday at 8 a.m. Action: pull the week’s numbers (new leads, consults booked, retainers signed, revenue collected) from your CRM and billing tool and post one digest. I run my firms on KPIs instead of meetings, and this zap is how the numbers show up without anyone compiling them.
10. New 5-star review to social post draft
Trigger: a 5-star review lands on your Google profile. Action: an AI step drafts a social post around the review text and drops it in a drafts folder or Slack for approval. Your best marketing copy is written by clients. This zap makes sure none of it dies unread on your listing page.
Zapier’s AI layer
Zapier stopped being a plumbing tool about two years ago. Three additions matter for firms.
AI steps let any zap call a model mid-flow: summarize this transcript, classify this lead, draft this reply. That’s what powers automations 7 and 10 above. Copilot builds zaps from plain English, so “when someone fills my Lawmatics form, text them and add a row to my tracking sheet” becomes a working zap without touching the editor. And Zapier MCP connects Claude directly to Zapier’s 8,000 apps, which means an AI agent can take real actions in your systems instead of only writing text. If you’ve already set up the connectors from my MCP guide, Zapier MCP is the multiplier: one connection, thousands of actions.
What it costs
| Plan | Price | Tasks per month | What you get |
|---|---|---|---|
| Free | $0 | 100 | Two-step zaps, enough to test ideas |
| Starter tier | ~$20-30/mo | ~750 | Multi-step zaps and filters; runs most of the 10 above |
| Professional | ~$50-75/mo | 2,000+ | Paths, webhooks, premium apps, custom logic |
A “task” is one action executed. A small firm running all 10 automations usually burns 500 to 1,500 tasks a month, so budget $30 to $75. Compare that against the paralegal hours these replace and the math ends fast.
When to graduate
Two honest exits. Make does the same job for roughly a third of the price at high volume, with a steeper learning curve; move when your Zapier bill passes $150 a month. n8n is self-hosted and near-free to run, but somebody has to maintain the server, so it only fits firms with technical staff or a developer on call. Neither is worth starting on. Build the habit on Zapier, migrate if volume ever forces it. Most firms never need to.
My rule, and your first zap
Across my 10 firms the standing rule is: any task a human performs twice a week gets an automation ticket. Not a discussion, a ticket. Staff stopped asking whether something should be automated and started asking why it isn’t yet.
Yours starts smaller. Open Zapier, connect your intake form and your phone system, and build automation #1 today. It takes under 30 minutes, and the next lead who fills out your form gets a text back before your competitor has checked their inbox.
