Why customers look
Why SimpleLegal customers are looking now.
SimpleLegal is an eBilling system with matter management. It no longer takes new implementations, and Onit is moving its customers to Unity through Activation. That makes this a natural moment to check the fit.
The common reasons to look are the same as with any eBilling platform: intake and workflow that live outside the system, reporting pulled into other tools, and integration upkeep that keeps growing.

vs Legal Tracker
SimpleLegal vs Legal Tracker.
These are the closest like-for-like pair: both are eBilling systems with matter management. Legal Tracker is priced on users and legal spend, and Legal Tracker Advanced adds rate management, matter pricing and RFP, and benchmarking. SimpleLegal is priced on legal spend.
The biggest practical difference is law firm support. With Legal Tracker, firms are onboarded into your own instance and your team supports them. With Onit, firms use Counsel Exchange and Onit supports them. On AI, Legal Tracker AI reviews invoices today, while Onit’s AI review comes with Unity. We implement both, and our Legal Tracker vs Onit Unity page compares Legal Tracker with the platform SimpleLegal customers are moving to.
vs LawVu
SimpleLegal vs LawVu.
LawVu positions itself as a legal operating system: intake, matters, contract lifecycle management and AI drafting in Word, alongside spend and eBilling. Its plans are priced by modules and users, and spend management sits in its top plan.
SimpleLegal is narrower: an eBilling system with matter management, priced on legal spend. Choose LawVu when contracts and legal requests belong in the same product as spend. Compare both on your own requirements and a sample of your invoices.

Frequently asked questions
What are the main alternatives to SimpleLegal?
Onit Unity, which Onit is moving SimpleLegal customers to, Thomson Reuters Legal Tracker, LawVu, Brightflag and Mitratech TeamConnect. The right one depends on your department size, how far beyond eBilling you need to go, and how you want your law firms supported.
Which eBilling and matter management system compares best with SimpleLegal for mid-size legal teams?
Legal Tracker is the closest like-for-like option, since both are eBilling systems with matter management. Brightflag targets mid-size companies, and Onit Unity is the path Onit offers SimpleLegal customers. Compare them on your billing guidelines, a sample of your invoices, and who supports your law firms.
What is the best SimpleLegal alternative for a small in-house team that wants easy setup?
Small teams usually weigh speed of deployment and cost of administration most. Check how long implementation takes, who supports your law firms, and the full cost including the mandatory accounts payable and single sign-on integrations. For an existing SimpleLegal customer, Activation on Unity is usually the least effort.
Brightflag vs SimpleLegal: which is better for eBilling?
Both are built around eBilling and spend control. Brightflag, now part of Wolters Kluwer, reviews every invoice line with AI. SimpleLegal has automated invoice review and rules-based approvals, and Onit’s AI review arrives with Unity. Test both on a sample of your own invoices.
Is HighQ an alternative to SimpleLegal?
Not directly. HighQ is Thomson Reuters’ collaboration platform for document sharing, workspaces and client portals, and it has no eBilling. The Thomson Reuters eBilling alternative to SimpleLegal is Legal Tracker.
Is Tonkean an alternative to Onit or SimpleLegal?
Tonkean is an intake and orchestration layer that sits on top of existing tools. It has no eBilling, so it can add intake and routing alongside an ELM platform but does not replace one.
Should SimpleLegal customers move to Unity or to another platform?
Activation on Unity keeps your setup and your pricing, and adds new features, so it is the shorter path. Moving to another platform makes sense when your requirements point there. Either way, the design, data, integration and process work decides whether the move pays off.
