Legal practice management software on AtlasOS, now in scoping
AtlasOS for legal practices is legal practice management software from Arke Technologies in Johannesburg, in scoping for South African law firms. It will add matter management, trust accounting integration and FICA compliance tracking to the AtlasOS core, whose client records, billing, deadlines and tasks are already live for accounting, audit and payroll practices.
Where the legal module stands today
AtlasOS is the operating system for professional services firms: one platform for a practice's clients, compliance, billing and communications, built and owned by Arke Technologies. The core is in production; the legal layer is in scoping. The table separates what a firm can use today from what is still being specified. Product detail is on the AtlasOS site (opens atlaspractice.app).
| Capability | Status for legal practices | What it does |
|---|---|---|
| Client and entity management | Live in the core | Companies, trusts and individuals, the relationships between them, and CIPC and SARS data |
| Billing and practice finance | Live in the core | Time-based, retainer and fixed-fee billing, multi-entity invoicing and client statements |
| Compliance and workflow | Live in the core | Scheduling, deadline alerts, task assignment and status tracking |
| Communications and inbox | Live in the core | Staff messaging, a client inbox, task comments and notifications |
| AI-assisted advisory | Live in the core | Conversational access to practice data: overdue tasks, compliance risks and client summaries |
| Branding and multi-tenancy | Live in the core | Your logo, colours, email templates and PDF headers, with full data isolation between firms |
| Matter management | In scoping | The matter as the unit of work, time, billing and record |
| Trust accounting integration | In scoping | Linking practice records to the firm's trust accounting |
| FICA compliance tracking | In scoping | Client due-diligence status and reviews across the whole client base |
What practice management software for lawyers must handle
Practice management software for law firms carries obligations that general business software does not. Check any system, ours included, against the rules a South African firm works under:
Trust money. The Legal Practice Act and the Legal Practice Council's rules require trust money to be kept apart from the firm's own money, accounted for and audited. A practice system must agree with the trust ledger, not compete with it.
FICA. Attorneys are accountable institutions under the Financial Intelligence Centre Act, so a firm must identify and verify its clients, keep the records and follow a risk management and compliance programme.
POPIA and privilege. Client files hold personal information, sometimes special personal information such as details of criminal proceedings, and much of it is privileged. Access should be limited to the people working on the matter.
Deadlines. Court dates, filing deadlines and prescription periods. A missed one can become a claim against the firm.
Fees. Time recorded against a matter must stand up if a client disputes a bill or has it taxed.

Billing software for legal practices, and time tracking
Billing is where legal software earns its keep. AtlasOS billing, live in the core today, supports time-based, retainer and fixed-fee billing, invoices across related entities and produces client statements. That matches how most firms charge: hourly for litigation and advice, retainers for corporate clients, and fixed fees for defined work such as wills or company registrations.
Time tracking software for legal work pays off only when time is recorded against a matter and a fee earner, reviewed before it is billed, and explained whenever it is written off. Matter-level time tracking is therefore a question for the legal module now in scoping, and a demo is the place to tell us how your fee earners record time today.
Integration with accounting platforms is on the AtlasOS roadmap. Until then, our ERP and accounting integration team connects practice systems to accounting packages such as Sage and Xero as a separate project.

Drafting, documents and contracts: which legal software does what
"Legal software" covers four jobs. The best software for a legal firm is usually a small set of tools sharing one client and matter record:
| Tool | What it does | Where AtlasOS fits |
|---|---|---|
| Practice management software | Clients, matters, deadlines, time, billing and compliance in one record | This is AtlasOS: the core is live, the legal layer is in scoping |
| Software for legal drafting | Templates, clause libraries and document assembly, usually inside Microsoft Word or Google Docs | Drafting stays in your word processor; AtlasOS is not a drafting tool |
| Software for legal documents | Storage, version control, search and access control for matter files | Microsoft 365 or Google Workspace, which we set up and govern; linking documents to AtlasOS matters is a scoping question |
| Contract management software | The life of a signed contract: obligations, renewals, expiry and approvals | A separate category, used mostly by in-house legal teams; AtlasOS does not replace it |
For document-heavy work now, we build SharePoint document management with permissions by matter, and our document intelligence service extracts data from legal documents at volume, with a person checking the output.
How to choose the best practice management software for law firms
01.
Start from the matter
Map how one matter moves from intake and FICA checks to billing and closure, and test every system against it.
02.
Check the trust accounting link
Ask how the system reconciles with your trust ledger and what your auditor will see.
03.
Test FICA and POPIA in the demo
Ask to see due-diligence status across the client base, and who can open a file.
04.
Be honest about time capture
If fee earners will not use it daily, the billing figures will be wrong.
05.
Ask where the data lives
Hosting region, encryption, access logs, and how you take your data with you if you leave.
06.
Check integration
Accounting, email and documents should connect, not be retyped.
07.
Price the whole term
Licences, migration, training and support over three to five years, not the monthly fee alone.
08.
Speak to a reference firm
For the AtlasOS core, that is Evolv Accountants.
Security, POPIA and oversight of your firm's data
AtlasOS stores data in PostgreSQL on Google Cloud SQL, with Firebase Authentication for sign-in, Firebase App Hosting and Cloud Scheduler, and each firm's data isolated at the database level, so no other firm on the platform can reach your clients' records.
AI-assisted advisory follows our AI principles: AI recommends and people decide, every AI action is logged and reviewable, and we never train models on client data, privileged material included, without explicit consent. The legal judgement stays with the attorney.
For oversight, the core shows compliance status across the whole client portfolio, with task assignment and status tracking, so a partner can see what is overdue without chasing individual inboxes.
Your data, credentials and documentation are yours, and so is the decision to leave. Arke Technologies (Pty) Ltd is a Level 1 B-BBEE contributor (135% procurement recognition; sworn affidavit available on request); company documents, our CSD supplier number and SARS tax compliance status are available on request. For the rest of your firm's technology, see IT for law firms and POPIA compliance.

In production at a professional services firm
The AtlasOS core runs today at Evolv Accountants, our reference site, which manages its compliance, UIF declarations, salary schedules, inbox and tasks on the platform. Read AtlasOS at Evolv Accountants, or see AtlasOS for accounting and tax practices, audit firms and payroll bureaux.
Atlas OS gives us visibility across 89 entities that we simply did not have before. The compliance tracking alone has saved us significant time every month.

Frequently asked questions
Is AtlasOS for legal practices available now? Show answer Hide answer
Not yet: the legal module is in scoping. Matter management, trust accounting integration and FICA compliance tracking are being specified now. The AtlasOS core, covering client and entity management, billing, deadlines, the inbox and AI-assisted advisory, is live for accounting, audit and payroll practices, and a demo shows it running alongside where the legal work stands.
What is practice management software for law firms? Show answer Hide answer
Practice management software for law firms is the system that holds a firm's clients and matters and runs the work around them: intake and FICA checks, deadlines, tasks, time recording, billing and reporting. Good systems link to trust accounting, documents and email, so each matter has one record instead of several spreadsheets and inboxes.
Which legal software is best for a South African firm? Show answer Hide answer
The best legal software is the one that fits how your matters run and meets South African rules: trust accounting under the Legal Practice Act, FICA client due diligence and POPIA. Test each candidate against one real matter, check how it reconciles with your trust ledger and where it hosts data, and speak to a firm that already uses it.
Does AtlasOS do trust accounting? Show answer Hide answer
Trust accounting integration is in scoping, not live. The legal module's aim is to link practice records to the firm's trust accounting, so billing and the trust ledger your auditor reviews agree. Until then, keep trust accounting in your existing accounting system, which we can support and integrate as a separate project.
Can AtlasOS track time and bill clients? Show answer Hide answer
AtlasOS bills clients today; time tracking by matter is not live yet. The core supports time-based, retainer and fixed-fee billing, multi-entity invoicing and client statements. Recording time against individual matters and fee earners depends on matter management, which is in scoping, so a demo is the place to see how the core handles time now and to tell us how your firm records it.
Is AtlasOS software for legal drafting or contract management? Show answer Hide answer
No. AtlasOS is practice management software: it runs clients, deadlines, billing and compliance. Legal drafting stays in Microsoft Word or Google Docs, and contract management software is a separate category used mostly by in-house legal teams. We set up and govern the document side in Microsoft 365 or Google Workspace, with access limited to the people on each matter.
