Check the same rules by hand.
Each cycle, reviewers worked through more than 80 pages for over 600 employees, comparing timecards, codes, remarks, leave, and adjustments. The review depended on concentrated manual checking.

Seven custom tools built around real payroll and accounting workflows.
I built these tools for my team to reduce repeated checks, bring scattered files together, and make reviews more consistent.
Time savings are workflow-specific estimates, not independently audited results or guarantees.
One workflow, before and after
Each cycle, reviewers worked through more than 80 pages for over 600 employees, comparing timecards, codes, remarks, leave, and adjustments. The review depended on concentrated manual checking.
The tool applies documented checks and organizes missing information, mismatches, and other exceptions for the reviewer. The team’s documented estimate is over eight hours saved per payroll audit; final decisions stay with the reviewer.
| Record | Check | Finding | Status |
|---|---|---|---|
| DEMO-101 | Required fields | No missing information | Checked |
| DEMO-102 | Hours and remarks | Remark needs reviewer confirmation | Review |
| DEMO-103 | Adjustment support | Supporting note is missing | Review |
The tool flags the finding. A person reviews the source and decides what happens next.
Team’s documented estimate: over 8 hours of manual auditing saved per payroll cycle.
The wider toolkit
The same approach helped with calculations, historical reviews, payments, reporting, and filing preparation. Open a workflow to see what changed.
Roughly 2 hours of manual Excel calculation and documentation work per applicable calculation workflow.
Estimated savings: over 8 hours of manual research and auditing for a substantial long-look-back review. HR completes and supports eligibility research before payroll reviews payable time and calculations.
Approximately 2–4 hours per pre-payment audit cycle, depending on the number of locations, jurisdictions, payment types, and exceptions in the batch.
Approximately 2–4 hours of manual work per monthly combination cycle.
The primary value is leadership visibility, departmental ownership, and decision support. A formal time study has not yet been completed, so no hourly savings figure is stated.
Quarterly federal tax calculation, reconciliation, and package preparation are brought into one workflow. A formal production time study has not yet been completed, so no hourly savings figure is stated.
Estimates describe separate workflows and are not added into an annual total. Actual savings depend on the files and exceptions. Reporting and quarterly filing preparation have no published hourly savings figure pending formal measurement.
How I approached it
I started by mapping the team’s steps, source files, required outputs, and review rules. The tools work with existing exports and familiar workbooks, PDFs, or dashboards, so the team could keep its established review process.
Development combined hands-on payroll knowledge, design, code, AI assistance, and repeated testing against expected results and known errors. The wider benefit is consistent checks, clearer evidence, and less reliance on someone remembering every exception.
Privacy and human control
Depending on the workflow, tools can process files locally in the browser without sending payroll information to an external website or database. This is not a blanket claim that every tool stores no data.
The tools do not release payments, make final payroll decisions, or independently submit federal tax returns. HR confirms eligibility where required; authorized reviewers investigate findings and approve the final work.
We can start with one report, one comparison, or one repetitive check and work out what would make it easier.
