A practical definition is the elapsed time between when work occurs and when the time entry is approved or released. Firms can also track creation lag, review lag, and release lag. Use consistent timestamps.

Same-Day Entry
Same-day review helps lawyers remember matter, purpose, duration, participants, document, outcome, and billing status. It also makes source activity easier to inspect while context is fresh.
Why Late Entry Creates Risk
Late entry can increase missed short tasks, wrong-matter selection, rounded durations, vague narratives, duplicate reconstruction, and month-end spikes. The main risk is loss of context.

Measure Distribution, Not Only Average
Track the percentage of entries completed same day, one day late, two to three days late, four to seven days late, and more than seven days late. An average can hide a small group of very old entries.
Look by Practice and Role
Patterns can differ by partners, associates, paralegals, litigation, transactional work, advisory work, and travel-heavy teams. Use the metric for process diagnosis, not simplistic ranking.
Diagnosing Lag and Reconstructing Work
Identify the source of delay and verify reconstructed activity before treating it as billable time.
Review area | What to check or do |
Find Root Causes | Late entry can come from timer friction, too many systems, poor mobile workflow, matter lookup problems, travel, approval complexity, weak habits, integration failures, or unclear policy. Different causes need different fixes. |
Use Activity for Reconstruction Carefully | Calendar, email, documents, calls, and browser activity can help reconstruct a day. They are evidence, not automatic proof that every detected minute is billable. |

Set a Policy
A time-entry policy should define deadline, responsible person, exceptions, escalation, review owner, training, and client-specific requirements. The policy should make timely entry easier rather than merely punish delay.
Use Reminders Intelligently
Specific reminders such as 'You have four draft entries from yesterday' are more useful than generic prompts. Notifications should be limited enough that users do not ignore them.
Connect Lag to Quality
Compare entry age with narrative corrections, matter changes, duration changes, prebill write-downs, and client adjustments. This shows whether late entry is actually creating downstream problems.
How MIRA Fits
MIRA captures activity from connected systems and presents reviewable time inside Microsoft Teams. The workflow is designed to reduce dependence on end-of-week reconstruction, while users remain responsible for final accuracy.

Frequently Asked Questions
What is time-entry submission lag?
It is the elapsed time between when work occurs and when the entry is created, approved, or submitted.
What should a law firm target?
Many firms prefer same-day or next-business-day entry, but the policy should reflect the firm's workflow and client requirements.
Can AI reconstruct late time?
AI can help surface source activity, but lawyers should verify matter, duration, and billing treatment.
Is late entry always inaccurate?
No, but delayed entry usually requires more reconstruction and can increase correction risk.
