Decisive Architectural Advantages
Trust Overdraft Protection
No competitor has IOLTA overdraft protection built in. Any withdrawal that would exceed the trust balance is rejected outright, with the available and requested amounts shown so staff know exactly why. Corrections bypass the check. Three-way reconciliation. Prevents disciplinary issues.
Smart Fuzzy Conflict Check
Clio has basic string matching. Aeion screens for exact matches and close-but-not-identical matches, surfacing each hit with a confidence level — definite, potential, or informational. Catches "Johnson & Johnson" vs "Johnson and Johnson."
Court Holiday Sets 2024-2030
No competitor has comprehensive holiday sets. Aeion pre-loads federal holidays through 2030, with CA and NY extending the federal calendar. Court-day calculation skips weekends and holidays, and advances to the next valid court day.
4-Tier Billing Rate Resolution
Clio supports 1-2 rate tiers. Aeion supports 4: matter > client > practice area > attorney default. Expired rates excluded. Auto-applies on time entry creation.
Statute of Limitations Engine
No competitor has SOL calculation. Aeion calculates SOL deadlines for CA, NY, TX, FL, Federal. 90-day warning. Auto-creates docket reminders. Pre-loaded rules with citations.
Calendar Month Arithmetic
SOL calculation handles month overflow correctly. Jan 31 + 1 month = Feb 28/29. Prevents missed deadlines from date-math edge cases.
Multi-Provider E-Signature
Clio charges for e-signature add-on. Aeion supports Native (Client Portal), DocuSign, and HelloSign — configured via settings, with graceful degradation when nothing's configured.
Contract Analytics
Clio's contract tracking stops at storing the file. Aeion analyzes what's actually inside it — clause frequency across your portfolio, obligation tracking, a renewal pipeline, and a risk score per contract — so you see exposure before it becomes a missed deadline.
Contract Obligation Tracking
Every contractual obligation is tracked individually, with compliance reminders, deadline notifications, and escalation workflows when something's at risk of slipping — so ongoing commitments don't get buried once the ink is dry.
Contract Renewal Pipeline
Aeion automatically identifies contracts approaching expiration, generates renewal quotes, and tracks each one through pending, negotiated, renewed, or expired — turning renewals into a managed pipeline instead of a spreadsheet someone forgot to update.
Contract Version Control
Every document revision is tracked with a full audit trail, side-by-side version comparison, and rollback to any prior version — so redlines and revisions never get lost in an email thread.
Document Automation
Clio's templates are limited. Aeion generates full documents from templates backed by a clause library, variable substitution, and automatic section cross-references — so drafting a standard agreement takes minutes, not a paralegal's afternoon.
Legal Analytics
Firm-wide metrics — matter pipeline, attorney utilization, revenue by practice area, and client profitability — give partners the numbers to make staffing and pricing decisions, not just a list of open matters.
LEDES 1998B/2000/2010 Export
No competitor ships native LEDES export. Aeion generates LEDES 1998B, 2000, and 2010 invoices for insurance billing directly from your time entries, with line items mapped to activity codes and full format compliance — no manual reformatting before submission.
Legal Research Support
Case law search, citation checking, precedent tracking, and research notes live in the same system as the matter they support — so research doesn't live in a separate tool disconnected from the work it's for.
Email Capture with Matters
Emails are captured and associated with the relevant matter automatically, with threading, full-text search, and attachment handling — so the matter file includes the actual correspondence, not just billing entries.
Calendar Sync
Deadlines sync two-way with Google Calendar and Outlook, with conflict detection and configurable reminders — attorneys see court dates and filing deadlines in the calendar they already live in, not a separate portal they have to remember to check.
Matter Templates
Standard templates by practice area auto-populate documents, tasks, and billing rates on matter creation — recurring matter types (a standard eviction, a routine incorporation) get set up in seconds instead of rebuilt from scratch each time.
Matter Lifecycle Management
Full matter lifecycle — client linking, practice-area assignment, status tracking, and document association — stays in one record from intake through closing, instead of scattered across email, a DMS, and a separate billing tool.
Frequently Asked Questions
Aeion calculates the balance from all non-archived ledger entries (deposits positive, withdrawals negative). On withdrawal, if the requested amount exceeds the balance, the request is rejected with an error carrying the available balance and the requested amount. Corrections bypass this check. This prevents IOLTA overdrafts that could result in bar discipline.
Names are normalized (lowercase, strip punctuation, sort words alphabetically) before comparison. Beyond exact matches, Aeion also scores how similar two names are even when they're not identical — a high-confidence match surfaces as a potential conflict requiring attorney review, while a lower-confidence match surfaces as an informational partial match. This catches variations like "Johnson & Johnson" vs "Johnson and Johnson."
Federal court holidays 2024–2030 are pre-loaded. CA and NY sets extend federal with state-specific holidays (César Chávez Day for CA, Lincoln's Birthday for NY). Court-day calculation skips weekends and holidays. If the result lands on a weekend/holiday, it advances to the next valid court day.
When creating a time entry, Aeion resolves the rate by priority: (1) matter-specific rate, (2) client-specific rate (contact or company), (3) practice-area rate, (4) attorney-default rate. Expired rates are excluded from resolution automatically. Falls back to your firm's configured default hourly rate.
Aeion looks up pre-loaded rules for the matching jurisdiction and tort type, applies the statutory period to the accrual date, and sets a warning date 90 days before expiry. It auto-creates docket reminders for the matter and handles calendar month arithmetic correctly (Jan 31 + 1 month = Feb 28/29).
Yes. Aeion supports Native (Aeion Client Portal), DocuSign, and HelloSign. Configure your provider in Legal → Settings → E-Signature. Credentials are stored encrypted. Gracefully degrades if not configured, with a clear error message instead of a fake success.
The withdrawal is blocked. Staff must deposit more funds or reduce the amount. Corrections can bypass the check but require special authorization and are audited. This hard-stop rule is absolute and prevents IOLTA overdrafts.
Aeion generates LEDES 1998B, 2000, and 2010 format invoices for insurance billing. Line items are mapped from time entries with activity codes. Supports expense categorization. Batch export for multiple matters.
Three types: (1) **calendar-day** — every day counts, (2) **business-day** — skips weekends only, (3) **court-day** — skips weekends + holidays. Each type handles month/year overflow correctly.
Names are normalized — lowercased, punctuation stripped, whitespace collapsed, words sorted alphabetically. "Johnson & Johnson" and "Johnson and Johnson" both normalize to the same form and register as an exact match. For names that aren't identical, a similarity score determines whether it's flagged as a potential conflict or a lower-priority informational match.
By default, archived clients are excluded. You can include them for re-activation workflows — useful when reactivating a former client for a new matter.
