The Best Clio Integrations and Apps in 2026
Clio is where a lot of law firms run matters, contacts, billing, and trust accounting — but it’s only as useful as the tools it talks to. The good news: Clio’s app directory has 250+ apps, the largest integration ecosystem in legal practice management. The gap: if the tool you need isn’t in the directory, you’re back to copying data between tabs by hand.
Here are the Clio apps and integrations actually worth setting up, grouped by what they do — and then the way to connect Clio to anything with an API, even when no native integration exists.
Accounting: QuickBooks Online and Xero
- QuickBooks Online — a bi-directional sync so trust accounting reconciles inside Clio, then transfers to QuickBooks as clean journal entries. The firm’s ledger stays accurate without rekeying invoices.
- Xero — the same idea for firms running their books in Xero.
Payments: LawPay
- LawPay — the deepest payment integration in Clio’s directory, writing card and eCheck payments straight to the matter ledger with trust and operating accounts kept separate for compliance.
Document management: NetDocuments, Dropbox, and Box
- NetDocuments — upload documents to NetDocuments and associate them with the right Clio matter, then manage files from either side.
- Dropbox and Box — attach and sync cloud files to matters so the whole team works from the same documents.
E-signature: DocuSign
- DocuSign — send signature requests from a matter and get signed PDFs back on the file, with the audit trail estate-planning and transactional firms need.
Productivity: Microsoft 365, Outlook, and Google Workspace
- Microsoft 365 / Outlook — sync email and calendar, and file messages to the matter they belong to without leaving Outlook.
- Google Workspace — connect Gmail, Google Calendar, and Drive so client communications and documents land on the right matter.
Scheduling and meetings: Calendly and Zoom
- Calendly — let clients book consultations that flow into your Clio calendar.
- Zoom — schedule and launch client meetings tied to the matter.
Marketing: Mailchimp
- Mailchimp — sync Clio contacts into Mailchimp audiences for client newsletters and firm updates.
No-code automation: Zapier and Fireflies
- Zapier — connect Clio to thousands of apps with simple triggers (“new matter → do X”). Good for basic field-mapping, not for reasoning over case data.
- Fireflies — capture and transcribe client calls, with notes that can flow back to the matter.
The AI way to connect Clio to anything: Carly
Native connectors cover the big legal systems. But the moment you need Clio tied to a tool that isn’t in the directory — or you want something smarter than “new matter → copy field” — you’ve hit the ceiling of native integrations and no-code triggers.
Carly is an AI executive assistant that connects to 200+ tools and, crucially, lets you bring your own API key to connect to anything with a REST API — Clio included. Instead of a fixed catalog, you get an agent that:
- Acts on triggers, 24/7 in the cloud — when a matter status changes, a bill goes overdue, or a new contact comes in, Carly does the next step without you in the app.
- Reasons over your data — not just “copy this field,” but “read the matter notes, draft a status update for the client, and send it for my review.”
- Ties Clio to the rest of your firm’s stack — updating a matter becomes one step in a workflow that also touches email (Gmail and Outlook), calendar, and tasks.
- Builds the workflow from a plain-English description — tell it “when a new intake matter is created, draft a welcome email and schedule a consult” and it interviews you, then builds it.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. See the full Claude + Clio integration guide for how the API-key connection works.
How to connect Clio to a tool with no native integration
- In Clio, create an API application and generate an access token from the developer settings.
- Paste your Clio token into Carly on the integrations page.
- Describe the workflow in plain English, and Carly builds it — connecting Clio to whatever else you need, on triggers, without your laptop open.
Frequently Asked Questions
Does Clio have an app directory?
Yes. Clio’s app directory includes 250+ apps and integrations spanning accounting (QuickBooks Online, Xero), payments (LawPay), document management (NetDocuments, Dropbox, Box), e-signature (DocuSign), productivity (Microsoft 365, Google Workspace), and more, plus Zapier for no-code automation and a REST API for custom connections.
What is the best Clio integration for automation?
For simple triggers, Zapier covers most apps. For automation that acts on triggers and reasons over your case data — and to connect Clio to tools with no native app — an AI agent like Carly connects via your Clio API token and runs workflows in the cloud.
How do I connect Clio to an app that isn’t in the directory?
Use Clio’s REST API. Create an API application in Clio to generate a token, then hand it to a platform that supports bring-your-own-API-key connections — Carly does this and can wire Clio to any tool with an API.
How much does an AI automation for Clio cost?
Carly’s AI agents start at $35/month, with non-AI workflow steps running free and unlimited. Your Clio plan and API access are separate.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
