Why firms don't switch

Data lock-in, painful migrations, and fear of breaking IOLTA.

Data silos everywhere

Practice management, a separate DMS, and spreadsheets. No single system of record.

Migration horror stories

3–6 month projects, weekend cutovers, manual mapping.

Trust accounting risk

Partners fear one misapplied trust dollar more than ugly UI.

Universal Migrator

Import matters, contacts, and files from CSV and file-share exports. You approve the mapping.

1

Plug in exports

Upload CSV exports from Clio, MyCase, Filevine, or a custom export. There is no Filevine or Clio live API.

2

AI mapping with human sign-off

AI maps messy headers automatically. You approve once.

3

Safe, replayable import

Replayable imports with error logs. Large jobs are possible; we have not published a 25k-matter SLA.

Native documents live in KaseOS (S3). Live NetDocuments or iManage OAuth is not part of this product.

Platform Capabilities

Everything you need.
Nothing you don't.

Purpose-built tools for modern law firms. No bloat. No legacy cruft. Just pure, distilled functionality.

Matter Management

Every case, every client, every deadline—organized in one intelligent workspace.

Smart Billing

Time entries, expenses, invoices, and payments. Trust deposits and applications as a sub-ledger.

Firm Analytics

WIP, AR aging, and trust reconciliation. Not a BI suite or revenue forecast engine.

Client Portal

Magic-link portal: matter status, messages, uploads. Firm logo and color. Payment URLs are not a live Stripe checkout yet.

Document Intelligence

Full-text search across documents plus matter search. Folder, version, and share-link workflows.

E-Signature

Send documents for signature with Dropbox Sign. Track status via webhooks. DocuSign and Adobe Sign are not implemented.

Document Generation

HTML, Markdown, and DOCX templates. Generate onto a matter from the Documents tab.

Calendar & Deadlines

Firm calendar with events, deadlines, and tasks. Google and Microsoft calendar OAuth. Docket rules skip weekends and holidays. Not a court-feed sync.

Smart Notifications

Notifications for deadlines, e-sign events, and matter updates. Email and in-app alerts with customizable preferences.

Document Versioning

Full document version history. Preview any version, see what changed, and restore previous versions with one click.

Matter Timeline

Complete activity timeline for every matter. See everything that happened, when, and by whom.

Enterprise Security

TLS in transit, firm isolation, role-based access, and audit logs on many writes. Not end-to-end encryption. Not SOC 2 certified.

Customization

Custom fields, layouts, and custom objects per firm. Automation rules exist in the API; there is no full workflow builder in the product UI.

Document Workflow

E-Signature built in

Send documents for electronic signature with Dropbox Sign. Track status from webhooks and save the signed PDF on the matter.

Provider-agnostic

Dropbox Sign is the live provider. DocuSign and Adobe Sign are not wired yet.

Real-time tracking

Track signature status in real-time. Get notified when documents are viewed, signed, or declined.

Secure by default

Signed PDFs automatically saved as new document versions. Complete audit trail for compliance.

Seamless integration

Send documents for signature directly from matters. No need to leave the platform.

How it works

1

Select document

Choose any document from your matter. No need to download or upload elsewhere.

2

Add signers

Add signers with their email addresses. Set signing order for sequential workflows.

3

Send & track

Send the request. Track status in real-time. Get notified when signed or declined.

4

Auto-save

Signed PDFs automatically saved as new document versions. Complete audit trail preserved.

Document Workflow

Document generation
from templates

Generate documents from HTML, Markdown, or DOCX templates. Merge matter, contact, and firm fields. Save onto the matter.

HTML Templates

Rich formatting with HTML. Perfect for letters, memos, and client communications.

Markdown Templates

Simple, readable templates. Great for quick documents and standardized forms.

DOCX Templates

Upload Word documents as templates. Preserve complex formatting and styles.

Matter context

Pulls data from the matter, contacts, firm, and custom fields when generating.

Matter-aware

Templates automatically know which matter, client, and case details to use.

Version control

All generated documents saved with full version history and audit trail.

How it works

1

Create template

Upload a DOCX file, write HTML/Markdown, or use our template builder. Add placeholders for dynamic data.

2

Fill from matter data

Generation pulls relevant data from the matter, contacts, firm, and custom fields.

3

Generate & review

Generate the document instantly. Review, edit if needed, and save as a new document version.

4

Send for signature

Optionally send the generated document for e-signature directly from the platform.

Time Management

Calendar & deadlines
unified in one view

Firm calendar for events, deadlines, and tasks. Google/Microsoft OAuth and docket rules that skip weekends and holidays.

Unified calendar

Events and deadlines in one view. No switching between systems.

Smart reminders

Automated reminders based on your preferences. Never miss a critical deadline.

Google / Microsoft sync

Sync Google or Microsoft calendars. Docket math from filing/trigger dates. Not a live court calendar feed.

Critical alerts

Visual indicators for critical deadlines. Color-coded by urgency.

Smart reminder system

Configure reminders that work the way you work. Set preferences per deadline or use firm defaults.

  • Set reminder preferences (days before, time of day)
  • Email and in-app notifications
  • Daily deadline reminder job
  • Overdue deadline alerts

Your AI workforce

Two assistants: one for the firm, one for each matter.

Donna

Your virtual COO

Firm-wide intelligence with read-only financial access.

  • Firm-wide WIP, AR, and trust risk
  • Read-only financial access
  • Finds aging invoices and SLA breaches

Rachel

Your billing & time associate

Matter-level assistant for billing and time tracking.

  • Drafts billing summaries
  • Flags unbilled time and trust balances
  • Helps with document generation and matter summaries
  • Proposes actions; never executes

Guardrails by design

  • Financial writes from AI require human confirmation; Rachel does not create invoices or send email
  • AI tool use is logged
  • RAG is JSON embeddings in-app, not a full firm-wide vector database

Client portal

Case tracker your clients actually use. No app download required.

Magic-link portal in the browser. Status, messages, uploads. Owners can set firm logo and primary color. Not a native app and not a PWA.

No app store friction

Opens from a text or email link

Live status

Discovery → Hearing → Settlement

Secure chat

No more WhatsApp + personal numbers

Card payments (when configured)

Portal billing lists invoices. Live Apple Pay / Stripe checkout is not shipped.

IOLTA-safe by design

Double-entry-style trust sub-ledger with overdraft checks. Not a full accounting system.

Append-only trust ledger
Database-enforced overdraft protection
Separate operating and trust accounts
Full audit trail for every transaction

We treat trust as a first-class sub-ledger. The system can refuse overdrafts and keep a reconciliation report. It does not replace your CPA, bank reconciliation, or jurisdiction IOLTA rulebook.

From demo to migration

Built with real firms

Built for 5–50 lawyer firms that are tired of stitching together practice tools.

FAQ

You export CSVs (and files, if needed). KaseOS maps columns with an AI-assisted mapper that you approve, then imports matters, contacts, and related records. There is no live Filevine, Clio, NetDocuments, or iManage API. Large imports are supported; we do not promise a 24-hour, zero-loss cutover for every firm.
