Most professional services don't bill in seconds. Lawyers go in six-minute increments, consultants in fifteens, contractors in halves and hours. An invoice that reads "2:17:43" looks like the output of a debugging session. "2.25 hours" looks like an invoice.
Timesheet's rounding feature does this for you. Set the increment once in Settings, choose the rounding direction, and the math is consistent across every invoice. Free on every plan, including Basic.
Why Round at All
Industry norms. Most professional services have established increments. Walking into a market with non-standard rounding makes clients squint at the invoice.
Cleaner invoices. "2.25 hours at $90 = $202.50" reads. "2 hours 17 minutes 43 seconds at $90" doesn't.
Predictable billing. Clients want to know the minimum unit. Anything below the increment falls into the next one. No surprises, no questions.
Easier downstream math. Round numbers go through accounting systems, audit reviews, and your own spot-checks more cleanly.
The Increments
Timesheet supports these rounding intervals:
| Interval | Result examples |
|---|---|
| Exact (no rounding) | actual time, to the minute |
| 5 minutes | 0:05, 0:10, 0:15, 0:20... |
| 6 minutes (tenth of an hour) | 0:06, 0:12, 0:18, 0:24... |
| 10 minutes | 0:10, 0:20, 0:30, 0:40... |
| 15 minutes | 0:15, 0:30, 0:45, 1:00... |
| 30 minutes | 0:30, 1:00, 1:30, 2:00... |
| 60 minutes | 1:00, 2:00, 3:00, 4:00... |
How Rounding Behaves
The rounding direction is a separate setting: round down, round up, or round to nearest. The default is round down. The table below shows round up, where any work begun in an increment bills for the full increment.
| Actual | 15-min rounding (up) |
|---|---|
| 0:07 | 0:15 |
| 0:16 | 0:30 |
| 0:31 | 0:45 |
| 0:46 | 1:00 |
| 1:22 | 1:30 |
With round down the same 0:07 would become 0:00, and with round to nearest it would become 0:00 (nearest 15-minute mark). The actual time is always preserved underneath. Reports can show both.
The Global Setting
Rounding is configured once, globally, and applies to every entry. There is no per-project rounding setting.
- Open Settings
- Find Timer Rounding
- Pick the interval (exact, 5, 6, 10, 15, 30, or 60 minutes)
- Pick the rounding type (down, up, or nearest)
- Save
This applies to:
- All new time entries
- Reports and statistics
- Exports and PDF invoices
What Reports Show
Statistics
Statistics can display rounded durations (the billing view) or actual durations (the productivity view). Pick whichever you're asking about at the moment.
Exports
CSV and Excel exports default to the rounded value. Many export templates support both columns side by side. Worth a quick look when you set the export template up.
Choosing the Right Interval
5 minutes
Best for: high-volume, short-task work like technical support. Choose if clients expect granular billing.
15 minutes
Best for: most professional services, consulting, knowledge work. The most common increment in the market, the safest default if you're not sure.
30 minutes
Best for: trades, on-site service, anywhere there's travel time or a minimum engagement.
60 minutes
Best for: retainers, training sessions, workshops. Work that naturally occurs in hour blocks.
6 minutes (tenth of an hour)
Best for: legal practice, which often bills in tenths of an hour. Timesheet offers a 6-minute interval natively, so 0.1-hour increments work out of the box, no manual conversion needed.
Ethics, Briefly
Rounding is standard. Rounding badly is not.
- A 1-minute email becoming a 15-minute charge looks like it. Group small tasks instead.
- If you handle many small interactions for the same client, batch them into a single entry per day.
- Be ready to explain your rounding policy if asked. "Standard 15-minute increments, documented in the contract" is a complete answer.
Documenting It
Tell clients the policy in writing.
In contracts and engagement letters.
Time is billed in 15-minute increments. Any portion of an increment is rounded up to the full increment.
On invoices. A single footnote line: "Billed in 15-minute increments."
Verbally during rate conversations. "Standard 15-minute rounding" should be part of the initial pricing conversation, not a surprise on invoice number one.
Handling the Awkward Cases
Very short tasks. A two-minute phone call at 15-minute round-up becomes a 15-minute charge. Fix it by grouping with other tasks for the same client that day, by switching the rounding type to nearest or down, or by choosing a smaller global interval.
Many small tasks on the same day. Two sensible patterns: a single daily entry with a summary description, or per-task with rounding only at the daily total. Pick one and stay consistent.
Non-billable work. Rounding doesn't matter for billing, but it does affect productivity reports. If you track non-billable time and want exact figures, set the global interval to exact (no rounding) so you see actual time.
Common Questions
Does rounding change my actual tracked time? No. Timesheet always records actual time. Rounding is applied for display and billing.
Can I see both rounded and actual? Yes. Task details show both. Exports can include both columns.
What if a client objects to my rounding? Discuss it. You can switch to exact (no rounding), a smaller interval, or a gentler rounding type. The rounding setting is global, so a change applies to all your work.
Is rounding up standard? In professional services, rounding up is a common convention ("any started increment is billed"). In Timesheet it is one of three rounding types, and round down is actually the default.
Can I round down? Yes. Round down is a configurable rounding type, and it is in fact the default. You can also choose round up or round to nearest under Settings > Timer Rounding.
Summary
The model:
- Pick an increment that matches your industry (15 minutes is the safe default)
- Set the global interval and rounding type once in Settings (down is the default direction)
- Actual time is always preserved, so reports can show both
- Document the policy in contracts and on invoices
- Be consistent, change with notice and not in the middle of a project
Where to Go Next
- Bill clients with custom rates to pair rounding with per-project rates
- Generate PDF invoices that show rounded times cleanly
- Export to Excel with both rounded and actual columns
