Building a reliable time record

Start with the weekly record

Use this page to organize a week of work into a clear time record. For U.S. payroll review, covered employers must keep accurate records for non-exempt workers, including hours worked each workday and total hours worked each workweek. The FLSA does not require a specific clock, app, spreadsheet, or timekeeping format.

The weekly total matters because federal overtime for covered non-exempt employees applies to hours worked over 40 in a workweek at not less than one and one-half times the employee's regular rate of pay. A workweek is 168 hours, set as seven consecutive 24-hour periods. Hours cannot be averaged across multiple workweeks for FLSA overtime.

Track the right fields

A useful time record needs the date, worker, start and stop times or duration, project, task, client, and billable status. Payroll records and basic time and earnings records have different retention periods under federal rules. Employers must preserve payroll records for at least three years and basic time and earnings records, such as daily start and stop records, for at least two years.

Client billing needs a different level of detail than payroll alone. A clean billing record separates billable and non-billable time, ties each entry to a client or project, and uses U.S. dollars for U.S. rate and invoice fields. A sample entry can read: March 5, 2026, Rivera, Acme onboarding, 2.5 billable hours, $125 hourly rate, implementation setup.

Judge open-source tradeoffs

Open-source time tracking is useful when your team wants visibility into the tool, control over hosting choices, or the ability to adapt workflows around internal requirements. The practical test is simpler: the record still has to be complete, accurate, retrievable, and usable for payroll, billing, and review. Source availability does not replace disciplined entries.

The common mistake is treating tool control as record control. A team still needs permissions, change history, backups, exports, and clear policies for manual edits. Privacy also needs attention. U.S. businesses handling personal information must avoid unfair or deceptive practices under Section 5 of the FTC Act, and California employee time-tracking data can fall under CCPA obligations for covered businesses.

Move beyond one-off tracking

A free or open-source tracker is enough for a small team that needs a weekly total, a project log, or a simple billing backup. It works best when one person owns setup, exports, and review. The risk grows when entries feed payroll, invoices, budgets, approvals, or client reporting across multiple people.

Everhour fits the managed workflow stage. Everhour Time Tracking captures task and project hours through live timers or manual entries, including inside supported project tools. Those hours can feed timesheets, reports, budgets, invoices, and payroll review, while admins use approvals, locked periods, reminders, and timer rules to keep records consistent.

Frequently Asked Questions

Can an open-source tracker meet U.S. timekeeping requirements?

Yes, if the records are complete and accurate. The FLSA requires covered employers to keep accurate records for non-exempt workers, including hours worked each workday and total hours worked each workweek. It does not require a specific app, form, or system.

Is open-source time tracking enough for overtime review?

Open-source tracking can support overtime review when it preserves a fixed workweek total. Covered non-exempt employees must receive overtime pay for hours worked over 40 in a workweek at at least 1.5 times the regular rate. A valid review cannot average hours across two or more workweeks.

Does weekend work need special handling in the tracker?

Weekend work should be recorded with the correct date, project, and hours worked. The FLSA does not require overtime premium pay solely for Saturday, Sunday, holiday, or regular rest-day work. Premium pay applies under the federal baseline only when weekly overtime is triggered, unless another law, policy, or agreement applies.

What should teams check before self-hosting time records?

Teams should confirm that records can be exported, retained, corrected with control, and protected from unauthorized access. Federal retention rules require payroll records for at least three years and basic time and earnings records for at least two years. Privacy controls also matter when employee activity data is stored.

Can manual entries in an open-source tracker be defensible?

Manual entries can be defensible when the team records time promptly, identifies the worker, date, project, and work duration, and reviews changes before payroll or billing use. Reconstructed entries become weaker when people fill a full week from memory without task detail or daily totals.

How does Everhour Time Tracking handle project and task hours?

Everhour Time Tracking captures time against tasks and projects through live timers or manual entries. Teams can track in Everhour directly or inside supported tools such as Asana, ClickUp, GitHub, Linear, Jira, Monday, Notion, Trello, and Basecamp, then use the entries for timesheets, reports, budgets, invoices, and payroll review.

How does Everhour keep approved time from changing later?

Everhour supports approval and lock controls for timesheets. Managers can approve, reject, or partially approve submitted time, and approved time stays locked for regular members. Admins can also lock completed periods, which protects payroll and billing records from late edits.

Make tracking easier to manage

Track time where work happens, review it before billing or payroll, and keep project records consistent. Everhour turns task hours into managed timesheets, reports, budgets, and invoices.
