Legal practice management software runs matters, time and billing, documents, calendars and, critically for Canada, trust accounting that satisfies the provincial law society. Most US-built tools handle trust as an afterthought; Canadian firms need reconciliation, client ledgers and reporting that would survive a spot audit. This guide covers the requirements, what the leading systems cost, and when a custom system for a specific practice area is the better decision.
We build custom software for professional firms in Canada, including client portals, intake and matter workflows, and we design around the applicable law society rules.

- Matter management: parties, conflicts, deadlines, limitation periods and status.
- Time capture and billing with LSO or provincial disbursement and HST handling.
- Trust accounting: separate trust ledgers per client, monthly reconciliation, and reporting to law society standards.
- Document management with version control and precedents.
- Calendar and deadline management tied to court rules.
- Client intake, conflict checks and engagement letters.
Canadian requirements
- Trust accounting rules from the Law Society of Ontario, Law Society of BC and the other provincial regulators, including monthly reconciliation and record retention.
- Privacy: PIPEDA and provincial law, plus solicitor-client privilege considerations for data hosting.
- Data residency: many firms require Canadian hosting for client files.
- HST on fees and disbursements handled correctly on invoices.
- Accessibility for client-facing portals under provincial law.
Established systems and costs
Clio, headquartered in Canada, is the default for small and mid-sized firms, priced per user per month with trust accounting included. PCLaw and CosmoLex serve accounting-heavy firms; Soluno is another Canadian option. Larger firms use Aderant or Elite. Prices run from under a hundred to several hundred dollars per user per month depending on tier.
Gaps appear in practice-specific workflow: real estate closings, immigration applications, personal injury settlement tracking, or high-volume small claims, where the generic matter model needs constant workarounds.
When custom legal software makes sense
- A practice area with a repeatable, document-heavy workflow that generic matter management forces into notes and spreadsheets.
- Client portals that go beyond document sharing: status tracking, intake questionnaires, e-signature, payments.
- Integration between intake, matter management and the firm's existing accounting or trust system.
- Volume practices where minutes per file matter more than features per user.
Custom legal software usually sits beside a practice management system rather than replacing trust accounting, which stays in a system built and audited for it.

What custom legal software costs
A client intake and matter workflow system with a portal, integrated with Clio or a similar platform, typically starts in the tens of thousands of dollars. Privacy and confidentiality design, access logging and Canadian hosting are part of the scope.
We quote fixed-scope and we say plainly when Clio's own workflow tools already cover the need.
How to choose
- Confirm trust accounting meets your law society's rules and ask for a sample reconciliation report.
- Map your highest-volume matter type end to end and mark every manual step.
- Confirm data residency and privilege handling in the contract.
- Price per user for three years.
- If the manual steps are in your highest-volume work, that is the custom case.
Frequently asked questions
Is Clio compliant with Canadian law society trust rules?
Clio is Canadian and supports trust accounting for Canadian jurisdictions. Firms remain responsible for reconciliation and record keeping under their regulator's rules.
Can custom software handle trust accounting?
It can, but it is a high-risk area with audit expectations. The usual approach keeps trust accounting in an established system and builds custom workflow around it.
Does legal software need Canadian data residency?
Many firms require it for privilege and privacy reasons. Confirm hosting location in writing.
How long does a custom client portal take?
A focused portal with intake, status tracking and document exchange integrated with practice management is typically a few months.
