Employee Timesheet Aggregator

The Problem

Adding up hours across multiple timesheets, shift exports or clock-in systems by hand is slow and genuinely error-prone — especially once overtime rules and different pay periods are involved.

About this problem

Timesheet exports are rarely uniform. Clock-in systems, shift apps and spreadsheets each use their own column names, date formats and time zones, and a single employee can appear several times per day with breaks, split shifts or a missing clock-out. Adding these up by hand, or with a spreadsheet formula, breaks down as soon as overtime thresholds or pay-period boundaries enter the picture.

People usually come looking for this when payroll day keeps turning into a manual reconciliation job, or after a miscounted total caused a correction. They want one repeatable process that reads the export they already have and produces totals they can trust, with odd entries flagged rather than silently included.

What's Included

• A tool that reads your actual timesheet export format
• Accurate per-employee totals, including overtime rules you specify
• Output as a clean summary ready for payroll
• Flagging anomalies (missing clock-outs, impossible shift lengths) for your review

What's NOT Included

• Running actual payroll or tax calculations (totals only, feeding into your existing payroll process)
• Integration directly into a specific payroll platform (can be scoped separately)
• Ongoing support for new timesheet formats as your systems change (re-scoped if that happens)

How It Works

1. I examine a sample of your real export to identify the columns, date and time formats, time zone handling and how breaks or split shifts are represented.
2. I write a parser that normalises every row into a consistent employee, start and end structure, and rejects or flags rows it cannot interpret.
3. I implement your overtime rules (daily or weekly thresholds, rounding conventions) as explicit, documented settings rather than hidden logic.
4. I add anomaly checks for missing clock-outs, overlapping shifts and implausibly long or negative shift lengths, and list them separately for your review.
5. I generate a per-employee summary as a clean CSV or spreadsheet and test it against a past pay period whose correct totals you already know.

In practice: you buy the service, send over whatever access or details the job needs, I investigate and do the work, and you confirm it's resolved before we call it done.

Frequently Asked Questions

How do I add up employee hours from a timesheet CSV automatically?

A small script can read the export, group the rows by employee and sum the worked time according to your rules. I build it around your actual file format so you can re-run it each pay period.

Can it handle overtime rules?

Yes, as long as you can state the rules clearly, for example hours over a daily or weekly threshold. They are set up as configurable values so they can be checked against your own calculations.

What happens if someone forgets to clock out?

Those rows are flagged as anomalies for you to review instead of being guessed at. You decide how to correct them before the totals are used.

Does it run payroll or calculate tax?

No. It produces hour totals only, which you then feed into your existing payroll process. Payroll and tax calculations are not part of this tool.

Can it plug straight into my payroll software?

Direct integration with a specific payroll platform is not included, but the output can be formatted for import where the platform accepts a file. A direct integration would be scoped separately.

What if my timesheet system changes its export format later?

The tool is built for the format I see at the start. If the columns or structure change, that is treated as a new request so the parser can be adjusted and re-tested.
