Integrations Are the Real Differentiator in Legal Practice Management Software
If your product can natively read from and write to the practice management system a firm already lives in, you reduce friction to near zero — no duplicate data entry, no context switching, and no reason to rip out what's already working.
The legal industry has a technology problem — not a shortage of software, but a surplus of siloed tools that don't talk to each other. For legaltech companies, the question is no longer whether to integrate. It's how quickly you can do it, and how invisibly you can fit into the workflows attorneys already rely on.
The Integration Landscape in Practice Management / Case Management
Practice management and case management software sits at the operational core of any law firm — handling matter lifecycle, deadlines, time tracking, billing, client communication, and document storage all in one place. It's the category that arguably needs integrations the most, because it touches every other system a firm uses.
The landscape here is genuinely mixed. A handful of cloud-native platforms like Clio and MyCase have invested meaningfully in open REST APIs and developer ecosystems. But a significant portion of the market — particularly legacy on-premise systems that have been mainstays at large firms for decades — offer limited or no public API access, making integrations dependent on vendor partnerships, data exports, or custom-built connectors. The result is that firms running modern stacks can automate freely, while those on older platforms often find themselves manually rekeying data between systems.
Why Integrations Actually Deliver Value
For legal tech startups: If your product can natively read from and write to the practice management system a firm already lives in, you reduce friction to near zero — no duplicate data entry, no context switching, and no reason to rip out what's already working. That's often the difference between a tool that gets adopted and one that quietly goes unused.
For large legal teams: A well-connected practice management system means matter data, billing records, deadlines, and client information flow automatically across the firm's tech stack — reducing administrative overhead, improving reporting accuracy, and letting lawyers spend more time practicing law and less time chasing down information across disconnected platforms.
Major Players and How to Integrate
Below is a breakdown of 18 leading practice management and case management platforms, their API availability, and how Supergood fits into the picture.
1. Clio
Clio offers one of the most mature and well-documented REST APIs in the practice management space, with broad coverage of matters, contacts, tasks, time entries, and billing. Supergood offers a custom API for Clio.
2. MyCase
MyCase provides a publicly available API, though its scope is more limited than Clio's — covering core matter and contact data but with fewer endpoints for billing and document management. Supergood offers a custom API for MyCase.
3. PracticePanther
PracticePanther has a REST API available to customers, and also supports native integrations via Zapier, making it one of the more accessible platforms for automation workflows. Supergood offers a custom API for PracticePanther.
4. Smokeball
Smokeball offers API access as part of its partner program and has built a growing integration ecosystem, particularly around document automation and e-signature tools. Supergood offers a custom API for Smokeball.
5. Rocket Matter
Rocket Matter provides API access for integrations, and has native connectivity with a number of billing and accounting tools, though the API is not as broadly documented as some cloud-native competitors. Supergood offers a custom API for Rocket Matter.
6. Filevine
Filevine has a REST API that covers its core project/matter and document management functionality, and is increasingly common in plaintiff-side litigation firms and personal injury practices. Supergood offers a custom API for Filevine.
7. Neos (formerly Needles)
Neos, Assembly Software's cloud platform, offers integration capabilities through its API and supports connections to a range of legal-adjacent tools, though deep API documentation is partner-facing. Supergood offers a custom API for Neos.
8. CARET Legal
CARET Legal (which has absorbed Zola Suite and AbacusLaw under its umbrella) provides API access and supports integrations with accounting, payment, and document platforms, though coverage varies by legacy product lineage. Supergood offers a custom API for CARET Legal.
9. Leap
Leap offers a partner API program and has built a number of native integrations, though access for third parties requires engagement with their partnership team rather than a fully open developer portal. Supergood offers a custom API for Leap.
10. Time Matters (LexisNexis)
Time Matters is a long-standing on-premise practice management system with deep roots at small and mid-size firms. API access is limited and primarily facilitated through LexisNexis partner programs rather than public documentation. Supergood offers a custom API for Time Matters.
11. ProLaw (Thomson Reuters)
ProLaw is an enterprise-grade practice and financial management platform commonly found at larger firms. It is not known for open API access — integrations typically require Thomson Reuters partnership engagement or custom development work. Supergood offers a custom API for ProLaw.
12. PCLaw (LexisNexis)
PCLaw is a legacy billing and accounting-forward practice management system with very limited native API exposure, making it one of the more challenging platforms to integrate with programmatically. Supergood offers a custom API for PCLaw.
13. PracticeMaster (Software Technology Inc.)
PracticeMaster, part of the Tabs3 suite, offers some integration capabilities through its SDK and data sync tools, but is not a platform with a modern public REST API — integrations are generally partner- or vendor-driven. Supergood offers a custom API for PracticeMaster.
14. CosmoLex
CosmoLex is a cloud-based platform that combines practice management with legal accounting. It offers limited API access, with most integrations occurring through built-in connections to tools like QuickBooks rather than an open developer API. Custom APIs can be created in-house, by third-party partners, or generated on self-serve integration platforms like Supergood.
15. Actionstep
Actionstep is a workflow-centric practice management platform with a public API and native support for integrations via Zapier, making it more accessible for firms and vendors looking to automate without heavy development work. Custom APIs can be created in-house, by third-party partners, or generated on self-serve integration platforms like Supergood.
16. Legal Files
Legal Files is an enterprise matter management system primarily used by corporate legal departments and government agencies. It has limited public API documentation, and integrations are typically handled through custom or partner-built connectors. Custom APIs can be created in-house, by third-party partners, or generated on self-serve integration platforms like Supergood.
17. Litify
Litify is built on the Salesforce platform, which means it inherits Salesforce's robust API capabilities and Zapier/n8n support — making it one of the more integration-friendly options for firms willing to operate within the Salesforce ecosystem. Custom APIs can be created in-house, by third-party partners, or generated on self-serve integration platforms like Supergood.
18. AbacusLaw
AbacusLaw, now part of the CARET family, is a long-standing on-premise practice management system with limited standalone API access — firms looking to integrate it with modern tooling typically require custom connector work or a migration path to CARET's newer cloud infrastructure. Custom APIs can be created in-house, by third-party partners, or generated on self-serve integration platforms like Supergood.
The Bigger Picture: Don't Add Work, Remove It
The firms and legal departments adopting new technology today are not looking for another portal to log into or another data silo to manage. The legaltech vendors winning long-term retention are the ones that make their software feel like a natural extension of the systems attorneys already use — not a replacement for them.
Whether you're a legaltech startup trying to land your first enterprise client, or a firm evaluating whether to consolidate your tech stack, integrations are no longer a feature. They're the baseline expectation.
Supergood builds custom APIs for the legal software that matters most — including many of the platforms listed above — so that firms, legal tech companies, and enterprise legal departments can connect their tools, automate repetitive work, and onboard or offboard without manual lift. If the system you need isn't already covered, Supergood's self-serve platform makes it possible to build the connection yourself.
