Quarter-Hour Rounding: Cleaner Billing with 15-Minute Increments

1/10/2026

My billing mess before quarter-hour rounding

I work with agencies that bill in 15-minute increments, but the reality of my week is 7-minute calls, 38-minute reviews, and 1-hour-02-minute strategy sessions. I used to export my logs, round everything up manually, and then rebuild totals for invoices. It was tedious and easy to get wrong. A couple of rounding mistakes meant extra explanations on invoices, which is never fun.

Rounding time to the next quarter hour, automatically

Teetrack now lets me round time entries to the next quarter hour (15-minute rounding) before totals and invoices are calculated. I set the rounding mode to Round up and the interval to 15 minutes. That means a 7-minute client call becomes 15 minutes, a 38-minute review becomes 45 minutes, and a 1-hour-02-minute session becomes 1 hour 15 minutes. It is exactly how my clients already expect to be billed.

How I enabled quarter-hour rounding in Teetrack

Open Settings and scroll to Time rounding settings.
Select Round up as the track rounding mode.
Choose 15 minutes as the rounding interval.
Save settings and keep tracking time as usual.

What changed in my billing workflow

Cleaner invoices: Rounded totals are consistent, so clients see the same 15-minute cadence on every line.
Fewer edits: I no longer fix durations or re-calc totals at the end of the month.
Faster reviews: The Summary view already shows the rounded totals I need.
Invoice-ready exports: Timesheets are ready to attach right away from Timesheets.
Client trust: Rounding rules are consistent and easy to explain on every billing cycle.

Why quarter-hour rounding is perfect for billable time

Quarter-hour rounding is a common standard for professional services because it balances precision and simplicity. By rounding each time entry, Teetrack keeps totals fair and predictable while still reflecting the actual work. It also removes the temptation to tweak entries after the fact, because the rule is the rule.
