Time Entry Increment Requirements
Billing increment rules specify the minimum time unit that outside counsel may record. Most law firms default to billing in six-minute (0.1 hour) increments, but some still use quarter-hour (0.25 hour) or even half-hour (0.5 hour) minimums. The impact of large increments is significant: a two-minute phone call billed at 0.25 hours at $500/hour costs $125 instead of the $17 it would cost at actual time. The problem compounds across hundreds or thousands of short interactions over the life of a matter. Email reviews, brief phone calls, calendar scheduling, and quick file consultations are individually small but collectively represent substantial overbilling when rounded up to larger increments. Increment rules should also address rounding practices. Even with 0.1-hour increments, consistent rounding up (e.g., recording 0.3 for every task that takes 12-18 minutes) creates a systematic billing inflation that is difficult to detect on individual entries but material in aggregate.
description Sample Clause Language
"Outside Counsel shall record time in increments of no greater than one-tenth (0.1) of an hour (six minutes). Time entries should reflect actual time spent, with rounding to the nearest tenth of an hour. Quarter-hour or half-hour minimum billing increments are not permitted."
"All time shall be recorded in increments of one-tenth (0.1) of an hour. Time entries must reflect the actual time spent, rounded to the nearest 0.1 hour. Systematic rounding up is prohibited. The Company reserves the right to audit time entries and reduce entries where a pattern of over-rounding is identified. Any email review or brief communication requiring less than three minutes of actual time shall be billed at 0.0 hours and noted as a no-charge entry, or aggregated with other brief communications into a single daily entry."
"Time shall be recorded in increments of one-tenth (0.1) of an hour based on actual time spent. Entries shall be rounded to the nearest 0.1 hour (i.e., 1-3 minutes rounds to 0.0, 4-9 minutes rounds to 0.1, 10-15 minutes rounds to 0.2). Routine communications (emails, voicemails, brief calls under three minutes) shall not individually exceed 0.1 hours. The Company will conduct quarterly statistical analyses of billing patterns. Timekeepers whose entries show a statistically significant rounding bias (more than 60% of entries at exact 0.1-hour intervals) may be subject to a 10% across-the-board reduction. Quarter-hour and half-hour minimum increments are strictly prohibited and will result in automatic adjustment to 0.1-hour billing."

lightbulb Why This Clause Matters
Billing increment inflation is one of the most underappreciated sources of legal cost overruns. A law firm billing in quarter-hour increments on a matter with 500 short interactions (emails, calls, brief reviews) per year could overbill by 50-125 hours annually compared to six-minute billing. At $500/hour, that represents $25,000-$62,500 in excess charges on a single matter — charges that are technically 'correct' under the firm's billing policy but do not reflect actual work performed.
warning Common Violations
Recording 0.25 hours for every email review regardless of whether it took 1 minute or 14 minutes
Billing 0.5 hours for a 10-minute phone call by using a quarter-hour minimum increment
Systematic rounding up where a timekeeper records 0.3 hours for every task between 12 and 18 minutes
Billing minimum increments for automated or template-generated communications
check_circle Enforcement Tips
Reject any invoice containing entries in increments larger than 0.1 hours and require rebilling
Run statistical analyses on timekeeper billing patterns to identify systematic rounding bias
Flag entries for email or phone communications that exceed 0.2 hours for manual review
Compare aggregate hours across similar matters to identify timekeepers with consistently higher totals
The Honor System Connection
Billing increments are a hidden lever in the honor system. Firms set their own increment policies, and most clients never question them. A firm billing in quarter-hour increments is not committing fraud — they are following their own policy. But that policy systematically charges you for time that was never worked. Requiring six-minute increments closes this gap between billed time and actual time.

Frequently Asked Questions
What billing increment should outside counsel use? expand_more
Outside counsel guidelines should require billing in one-tenth of an hour (six-minute) increments. Quarter-hour and half-hour minimums are prohibited. Time entries must reflect actual time spent rounded to the nearest 0.1 hour. Systematic rounding up should be monitored through statistical analysis.
How much does quarter-hour billing inflate legal costs? expand_more
A firm billing in quarter-hour increments on a matter with 500 short interactions per year could overbill by 50-125 hours compared to six-minute billing. At $500 per hour, this represents $25,000-$62,500 in excess charges on a single matter for time never actually worked.
How do you detect systematic rounding in legal billing? expand_more
Run statistical analyses on timekeeper billing patterns. If more than 60% of entries fall at exact 0.1-hour intervals or consistently round up, this indicates systematic bias. Automated tools can flag these patterns across all timekeepers and generate exception reports for review.
