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

The problem with manual rounding

Many professionals bill in 15-minute increments but track time in real minutes. Without automatic rounding you end up exporting your logs, rounding every entry manually, and rebuilding totals at invoice time. A couple of mistakes mean extra explanations on the invoice, and clients lose trust in your billing.

Rounding time to the next quarter hour, automatically

Teetrack rounds each time entry to the next quarter hour (15-minute rounding) before totals and invoices are calculated. Set the rounding mode to Round up and the interval to 15 minutes in Settings. 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 — exactly how most clients expect to be billed.

Round-up table at 15 minutes

• 0 minutes tracked → 0h billed (no entry created)
• 1–15 minutes → 0.25h billed
• 16–30 minutes → 0.50h billed
• 31–45 minutes → 0.75h billed
• 46–60 minutes → 1.00h billed
• 61–75 minutes → 1.25h billed

Worked examples at $120/hour

• 23-minute task → rounded up to 0.50h → $60.00
• 7-minute task → rounded up to 0.25h → $30.00 (clients sometimes flag tiny entries; consider a minimum-billable policy)
• 62-minute task → rounded up to 1.25h → $150.00
• 38-minute review → rounded up to 0.75h → $90.00

Round up, round to nearest, or round down

Round up is the standard for professional services because it absorbs the cost of context switching and small overruns. Round to nearest is fairer to long-term retainer clients who value predictable totals. Round down is rarely useful for billing but can be helpful when reporting internal capacity. The right policy depends on your contract; pick one and apply it consistently so clients never have to guess how you compute totals.
