Many professionals bill in increments rather than exact minutes. Lawyers might bill in 6-minute increments, consultants in 15-minute blocks, and contractors in 30-minute chunks. Timesheet's rounding feature automatically adjusts your tracked time to these intervals.

This guide shows you how to configure rounding for clean, professional invoices.

#Why Round Time?

#Industry Standards

Many industries have established billing increments:

  • Legal: Often 6-minute (0.1 hour) increments
  • Consulting: Typically 15-minute increments
  • Trades/Contractors: Often 30-minute or hourly increments
  • Creative services: Varies widely

#Simpler Invoices

Rounded time creates cleaner invoices:

  • 2.25 hours instead of 2:17:43
  • Easier for clients to understand
  • More professional appearance

#Predictable Billing

Clients appreciate knowing:

  • Minimum billing increment
  • How time will be calculated
  • No surprises from odd minutes

#Simplified Calculations

Round numbers are easier to:

  • Calculate totals
  • Verify accuracy
  • Process in accounting systems

#Rounding Options in Timesheet

Timesheet offers several rounding intervals:

IntervalExamples
5 minutes0:05, 0:10, 0:15, 0:20...
10 minutes0:10, 0:20, 0:30, 0:40...
15 minutes0:15, 0:30, 0:45, 1:00...
30 minutes0:30, 1:00, 1:30, 2:00...
60 minutes1:00, 2:00, 3:00, 4:00...

#How Rounding Works

When rounding is enabled, time is typically rounded up to the nearest interval:

Actual Time15-min Rounding
0:070:15
0:160:30
0:310:45
0:461:00
1:221:30

Note: Rounding typically rounds up, following the principle that any work started in an increment should be billed for that increment.

#Configuring Global Rounding

#Access Rounding Settings

  1. Go to Settings
  2. Find Time Rounding or Billing Settings
  3. Select your preferred interval
  4. Save

#This Affects

  • All new time entries
  • Reports and statistics
  • Exports and invoices

#Per-Project Rounding

Different clients may have different expectations. Timesheet allows per-project rounding settings.

#Setting Project-Specific Rounding

  1. Open the project
  2. Go to project settings
  3. Find Rounding setting
  4. Select:
    • Use global setting (inherits from app settings)
    • Custom interval (choose specific interval)
    • No rounding (track exact time)
  5. Save

#When to Use Per-Project Rounding

Different client agreements:

  • Client A: 15-minute increments per contract
  • Client B: Actual time per their preference
  • Client C: 30-minute minimums

Different work types:

  • Consulting project: 15-minute rounding
  • Support tickets: Exact time
  • Retainer work: Hourly rounding

#Rounding and Reports

#In Statistics

Statistics can show either:

  • Rounded durations (for billing accuracy)
  • Actual durations (for productivity analysis)

Check your settings to ensure you're viewing the appropriate data.

#In Exports

When exporting data:

  • Rounded values appear by default
  • Some exports may offer both rounded and actual columns
  • Verify your export includes the values you need

#Best Practices for Time Rounding

#Document Your Policy

Communicate your rounding policy to clients:

  • In contracts and engagement letters
  • On invoices (footnote)
  • Verbally when discussing rates

#Example Contract Language

"Time is billed in 15-minute increments. Any portion of an increment will be rounded up to the full increment."

#Be Consistent

Once you establish a rounding policy:

  • Apply it consistently to all work
  • Don't change mid-project without notice
  • Document any exceptions

#Consider the Ethics

Rounding is standard practice, but:

  • Don't abuse small tasks (a 1-minute email shouldn't become 15 minutes)
  • Group related small tasks together
  • Be prepared to explain your billing if questioned

#Match Industry Norms

Research what's standard in your industry:

  • Ask peers what they do
  • Check professional association guidelines
  • Consider client expectations

#Choosing the Right Interval

#5-Minute Rounding

Best for:

  • High-volume, short tasks
  • Technical support
  • When clients expect precision

Consider if:

  • You have many small tasks
  • Clients question larger increments

#15-Minute Rounding

Best for:

  • Professional services
  • Most consulting work
  • General knowledge work

The sweet spot for most professionals—meaningful increment without excessive rounding.

#30-Minute Rounding

Best for:

  • Trades and contractors
  • On-site service calls
  • When minimum engagement is expected

Consider if:

  • You have travel time built into services
  • Industry standard is half-hour minimums

#60-Minute Rounding

Best for:

  • Retainer work
  • Training sessions
  • Workshop delivery

Consider if:

  • Work naturally occurs in hour blocks
  • Clients expect hourly billing

#Handling Edge Cases

#Very Short Tasks

A 2-minute phone call with 15-minute rounding becomes a 15-minute charge. Handle this by:

  • Grouping with related tasks
  • Using a smaller rounding interval for small tasks
  • Having a minimum billable policy instead of rounding

#Multiple Short Tasks Same Day

If you have many small tasks for the same client:

  • Consider daily totals instead of per-task rounding
  • Or batch related small tasks together
  • Document your approach consistently

#Non-Billable Time

For non-billable work:

  • Rounding may not matter
  • Consider tracking actual time for internal analysis
  • Use per-project settings to disable rounding

#Common Questions

Does rounding affect actual tracked time? No. Timesheet records actual time. Rounding is applied for display and billing purposes.

Can I see both rounded and actual time? Yes. Task details typically show both values. Exports can include both columns.

What if a client objects to rounding? Discuss their preferences. You can set their project to no rounding or a smaller interval.

Is rounding up standard? In professional services, yes. Rounding up is the norm, following "any started increment is billed."

Can I round down instead? This isn't typical, but you could manually adjust entries if needed for specific situations.

#Summary

Time rounding in Timesheet helps create professional invoices:

  • Choose your interval: 5, 10, 15, 30, or 60 minutes
  • Configure globally: Default setting for all projects
  • Per-project override: Different settings for different clients
  • Communicate clearly: Document your rounding policy
  • Apply consistently: Same rules for all work

Professional billing means predictable, transparent invoices—and time rounding helps achieve that.

#What's Next?

With rounding configured:
