LEAP vs OneLaw: Which Legal Practice Management Software Is Right for Your New Zealand Law Firm?

LEAP vs OneLaw at a glance

If you are comparing LEAP and OneLaw, you are looking at two serious practice-management options for New Zealand law firms. Both offer cloud hosting, matter and document management, billing, trust accounting, time recording, reporting, Microsoft integration, data migration and local support.

The difference is less about whether either system can run your practice and more about the kind of platform you want.

Choose LEAP if you want a broader legal productivity platform, with preconfigured NZ matter types, automated legal documents, legal publishing, a client portal, a mobile app and an established suite of legal AI tools.

OneLaw could be right for you if you prioritise a New Zealand-owned and developed system, familiar local accounting workflows, simplicity and highly localised support.

The real question is not whether moving to LEAP is worth the effort. It is whether OneLaw is still helping your firm move forward. If your team is ready for more automation, deeper legal content, integrated AI and a broader productivity platform, LEAP gives you more room to grow.

This comparison reflects publicly available product information as at 11 June 2026. Confirm current functionality, packaging, roadmap delivery and pricing directly with each provider.

The biggest difference: platform breadth or local simplicity

OneLaw was founded in Christchurch in 2009 in response to New Zealand firms wanting modern software, local support and a less complicated user experience. Its proposition remains deliberately focused: a complete practice and document-management system designed around the needs of NZ firms.

We combine a global product platform with NZ-specific matter types, legal documents, trust accounting, content and support. With LEAP, you can go beyond core practice management into legal publishing, document automation, client collaboration, legal research, drafting AI and mobile work.

That gives you an important strategic choice:

• OneLaw gives you a focused, local system shaped around the way many NZ firms already operate.

• With LEAP, you get a broader connected platform so you can automate more of the legal work itself.

Neither model is inherently better for everyone. You should measure how much time each system removes from real work, how much process change it requires and how confidently your operational users can run it.

Matter, client and document management

OneLaw describes itself as client-centric. Its financial summary, deeds storage and custom Info Sheets help users see the wider client relationship and capture matter-specific information. Its document capabilities include Microsoft integration, categories and filtering, bundling, version control, full-text search, precedent libraries, clause libraries and document assembly.

We centre your work in an electronic matter file and provide more than 1,000 preconfigured matter types. You can reuse client and matter data to populate documents, forms and correspondence. We also include legal publishing assets and connect with Microsoft 365, helping you move from matter information to finished legal documents with less re-entry.

Consider OneLaw when: you value a familiar client-centric structure, strong document management and firm-controlled precedent libraries.

Choose LEAP when: you want more practice-area structure, legal forms and document automation provided as part of the platform.

Legal content and document automation

Both systems support document assembly, but their content models differ.

OneLaw helps firms standardise their own output through stationery, precedent and clause libraries. Info Sheets capture custom matter information that can populate documents. This gives the firm control over the content and processes it builds into the system.

We combine your documents with preconfigured matter types, forms and legal publishing assets. Generator can draw from your past work, LEAP forms, AI-generated drafts and optional By Lawyers precedents. This can reduce your setup work if you want an existing legal-content foundation instead of building every resource internally.

Have us and OneLaw automate three documents your team produces frequently. Measure the setup required, the fields populated, the editing still needed and how updates are governed.

Trust accounting, billing and reporting

Trust and office accounting are core strengths in OneLaw's proposition. It advertises NZ trust-accounting functionality, bank downloads for reconciliation and periodic interest, requisitions, billing and statement workflows, debtors management, financial summaries and extensive reporting. Its NZ-based support team includes former practice managers and trust accountants.

We provide in-built office and trust accounting, billing, time capture, pre-billing and reporting connected to the matter. The wider benefit is that your financial work sits alongside matter management, automated documents, legal content and client collaboration.

Do not select either system based only on the phrase "NZ trust accounting". Have your trust accountant and practice manager test:

• Daily receipts, payments, transfers and approvals.

• Reversals, corrections and audit trails.

• Month-end reconciliation and inspectorate reports.

• Interest-bearing deposits and any controlled-account requirements.

• Billing, WIP, disbursements, write-offs and debtor follow-up.

• Financial reporting by author, team, office and practice area.

OneLaw's April 2026 roadmap also lists planned changes including a split-ledger option and further trust-accounting and billing improvements. Ask which roadmap items are delivered before relying on them.

AI and legal work

This is currently one of the clearest differences between the platforms.

We provide a live suite of legal AI capabilities:

Matter AI can answer questions about matter correspondence and create matter-related drafts.

LawY supports research and drafting, with optional verification by qualified New Zealand lawyers.

AI Prompts create first drafts using matter context.

Generator can produce documents using firm precedents, LEAP forms, LawY and optional By Lawyers content.

AutoTime supports intelligent time recording.

OneLaw currently advertises Find Time, which suggests missing time entries from user activity.

If broad, integrated legal AI is an immediate requirement, we offer the stronger documented capability today. If you prefer a more cautious adoption path and mainly want smart operational assistance, OneLaw's approach may still be sufficient.

In either case, insist on security details, source visibility, verification controls and a clear professional-use policy.

Mobile and remote work

Both systems are cloud hosted and support remote access.

We also provide a dedicated mobile app so you can access matters, communicate and record time away from your desk. Calls made through the app can generate time entries linked to the relevant matter.

OneLaw's roadmap lists a mobile application for time recording as work planned for the future, as of early 2026 - as of writing this comparison, they do not have a native mobile app. Firms with lawyers regularly working from court, client sites or away from a laptop should test the current mobile experience of both systems rather than assuming browser access and a dedicated app are equivalent.

Integrations and client experience

OneLaw integrates with selected NZ-relevant partners. Publicly listed examples include InfoTrack, Xero, VXT and identity and AML services. Its approach is to remain the core practice platform while connecting to specialist providers where useful.

We integrate with Microsoft 365, InfoTrack, Xero, MYOB and marketplace applications like VXT and many more. We also include LawConnect for secure client document sharing, signatures, invoice delivery and statements, giving you a stronger client-collaboration capability out of the box.

Create a list of every system you rely on, then have us and OneLaw identify whether each connection is native, one-way, two-way, partner-built, API-based or manual. "Integrates with" can describe very different experiences.

Migration, training and support

OneLaw makes local migration and support a central part of its offer. It advertises full historical migration from most competing systems, a dedicated project manager, capped onboarding costs, personalised training and a NZ-based helpdesk staffed by people with law-firm experience. Its website says firms usually need two to three days of catch-up processing, with some pages describing one to two days depending on the migration.

We provide data transfer, system setup, training, NZ-based support, Client Success, live chat, self-service resources and LEAP University. Our transition team has moved more than 4,250 firms globally from over 25 software systems.

The most important distinction will be the migration plan offered to you. Have us and OneLaw specify:

• Exactly which historical data and documents will transfer.

• How trust and office balances will be reconciled.

• Whether old data remains editable and reportable.

• Who configures matter types, permissions, templates and reports.

• The cutover process, expected catch-up work and post-launch support.

• References from NZ firms that migrated from your current system.

Pricing and commercial terms

Neither provider publishes a simple complete NZ price on the product pages reviewed for this comparison. Request a written proposal from us and OneLaw covering licences, implementation, migration, training, support, annual increases, integrations, optional content and contract length.

Do not assume the platform with fewer features will cost less, or that the platform with more features will replace every existing cost. Map which current tools can genuinely be retired and which will remain.

Questions to ask in both demonstrations

• Can you run one of our actual matters through the system from opening to final reporting?

• Which matter types, forms, precedents and workflows are included on day one?

• How much configuration is required before our team can work productively?

• Can our trust accountant complete a representative month-end process in the demo?

• How are incorrect financial transactions corrected and audited?

• Which AI and mobile capabilities are live now, rather than on the roadmap?

• What historical data will be migrated and how will its integrity be checked?

• What does local support include, and what are the response hours and escalation process?

• What is the full cost over three years?

• Can we speak with firms of a similar size and practice mix that changed from our current system?

Frequently asked questions

Is OneLaw more New Zealand-specific than LEAP?

OneLaw is New Zealand-owned, designed, developed and supported, and its sole focus is NZ legal practice and document management. We combine a global platform with NZ-specific matter types, forms, accounting, content and a NZ-based team. Compare the actual local workflows and support you will receive rather than relying only on company origin.

Do both LEAP and OneLaw support NZ trust accounting?

Yes, both advertise NZ trust-accounting functionality. The systems structure some processes differently, so your trust accountant should test real transactions, controls and reports before a decision.

Which is better for document automation?

Both platforms support document assembly. OneLaw provides firm precedent and clause libraries driven by custom Info Sheets. We combine your content with preconfigured matter types, legal forms, publishing assets and AI-assisted generation. Choose LEAP if you want a larger prebuilt content and automation layer.

Which has stronger AI capabilities?

As at 11 June 2026, we provide a broader live suite covering legal research, matter analysis, drafting, document generation and time recording. OneLaw offers Find Time and has published broader AI capabilities on its roadmap.

Does OneLaw have a mobile app?

OneLaw's April 2026 roadmap lists a time-recording mobile app as planned beyond 12 months. We currently provide a dedicated mobile app. Confirm the latest position before you decide because roadmaps can change.
