iTimeKeep Alternative for Law Firms: Passive Capture vs Active Mobile Entry

iTimeKeep, made by Bellefield Systems, is one of the most widely used legal time-entry tools across Am Law and mid-market legal practices. Its core promise is straightforward: timekeepers can log time against matters from their phone, sync entries directly to the firm's billing and practice management system, and stay current without returning to their desk. For firms already running Aderant, Elite Enterprise, or a similar platform, the integrations are mature and the deployment model is well-understood.

So why do some firms begin evaluating alternatives? Usually not because iTimeKeep fails at its stated job, but because the nature of fee-earner work has shifted. When a typical billing day includes dozens of brief interactions — short email exchanges, quick document reviews, a five-minute Teams call on a matter, a phone call answered between meetings — a mobile entry tool still requires the timekeeper to interrupt what they are doing and log it. The tool is only as complete as the human's willingness to record every interaction, no matter how small.

This article explains where that model works well, where passive automatic capture changes the equation, and how Timentry compares for legal and professional-services firms.

Where mobile time entry fits well

For any firm with a disciplined timekeeping culture and a small-to-medium number of active matters per fee earner, mobile-first entry covers the majority of billable work:

Long tasks (drafting, research, depositions) are easy to track with a running timer
Court appearances, client meetings, and travel can be logged with a few taps immediately after
Tight integration with established billing platforms means entries reach the billing system without re-keying
The mobile-first model suits timekeepers who are frequently out of the office or in court

The problem is not the tool. The problem is the category of billable work it does not naturally capture.

The capture gap: micro-activity and fragmented desk work

Mobile and timer-based entry tools share a common assumption: the timekeeper knows they are doing billable work and actively decides to record it. That assumption is reliable for long, concentrated tasks. It holds less well for the fragmented activity that now makes up a large share of a fee earner's day:

Three quick emails replied to on a matter between calls
A document reviewed and annotated for ten minutes before a meeting
A Zoom session that wasn't on the calendar but ended up being twenty minutes on client work
A phone call taken at the desk, handled and forgotten by end of day

Each of these is billable. None is likely to be logged in a mobile entry tool — the friction of opening an app for a two-minute interaction is too high, and by end of day the memory of each interaction is gone.

Research consistently shows that reconstruction-based timekeeping understates actual hours worked. The gap between what timekeepers record and what they actually did is a direct write-down, not a pricing decision.

What passive capture adds

Passive time capture approaches the problem differently. Instead of asking the timekeeper to track their work, it observes what work is happening — across email, calendar, documents, meetings, and calls — and assembles a complete record automatically. The timekeeper then reviews and approves a full day's worth of drafted entries, rather than reconstructing from memory.

Timentry captures passively via a lightweight desktop agent and cloud connectors for Microsoft 365, Google Workspace, Zoom, and telephony providers. Each piece of activity is clustered into draft time entries using AI-drafted billing narratives against the appropriate matter. Attribution uses deterministic rules first — matter numbers in document names, client sender domains in emails, client names in calendar entries — with AI as a fallback only where the rules cannot resolve the match. Compliance rules are enforced before submission: OCG requirements, prohibited task codes, and client-specific billing rules are checked at the desk so entries that would be rejected are flagged before the invoice goes out.

Manual live timers are still available for work where the timekeeper wants to track explicitly — up to ten concurrent timers — alongside a weekly timesheet grid for those who prefer a structured review. Captured-but-unbilled hours, realisation rate, and utilisation are visible in real time rather than at month-end.

Side-by-side: mobile entry vs passive capture

| Capability | Mobile-first entry (iTimeKeep model) | Timentry | |---|---|---| | Mobile time entry | Yes, purpose-built | Covered via review workflow | | Passive desktop capture (email, docs, calls) | Not the core model | Yes — desktop agent + cloud connectors | | Automatic matter attribution | Manual lookup and selection | Deterministic rules, AI fallback | | AI-drafted billing narratives | Not core | Yes — generated from captured activity | | OCG / compliance enforcement before submission | Not built in | Yes | | Real-time unbilled, realisation, and utilisation view | Varies | Yes, in real time | | Manual live timers | Yes | Yes (up to 10 concurrent) | | Microsoft 365 / Google Workspace / Zoom connectors | Not native | Yes | | Integration with practice management billing systems | Strong (Aderant, Elite, etc.) | Via time-entry export and review workflow | | SSO and encrypted integration credentials | Varies | Yes |

How to tell whether passive capture would close a real gap

A passive capture approach earns its place if:

Fee earners acknowledge they forget to log short email exchanges and quick document reviews — even when they intend to
Write-downs happen regularly because narratives are thin or time cannot be reliably reconstructed at billing time
Timesheet completion falls on busy days, precisely when the most billable work occurred
One or more clients bill under outside-counsel guidelines and compliance is currently caught only when invoices bounce from e-billing portals

If your timekeepers are thorough active trackers, the matters per fee earner are manageable, and OCG compliance is handled upstream in your billing platform, the incremental value of passive capture is smaller and the change management cost of switching tools may not be justified.

Where Timentry fits

Timentry is automatic, AI-powered time capture built for professional-services firms — legal, accounting, healthcare, and architecture and engineering. For firms currently on iTimeKeep, the most useful first step is a pilot with a small group of fee earners to measure the difference in captured hours before making a firm-wide decision. The gap between what an active-entry tool records and what passive capture finds tends to be larger than expected.
