ROI and Business Case

This document sets out the financial case for automating your payroll processing workflow. It translates the hours, errors, and delays identified during the process mapping session into real dollar figures, shows exactly what changes after the automation goes live, and gives you the numbers needed to make a clear go or no-go decision. All figures are based on the details confirmed during your session and cross-checked against industry benchmarks. Where an assumption has been estimated rather than confirmed, that is flagged in the assumptions log at the end of this document.

01What the current process is costing you

The three highest-friction steps in your current process account for the majority of that time and carry the greatest risk of error or delay.

• Collecting timesheets from managers (Step 2, ~45 min per cycle): This is the single biggest bottleneck. A single late submission holds up the entire payroll run. The Finance Manager sends individual reminders manually, with no automated follow-up, meaning the process restarts from zero every pay period.
• Reconciling hours against the published schedule (Step 3, ~40 min per cycle): Hours from Deputy must be manually cross-checked against the shift schedule in a spreadsheet. Discrepancies, missed shifts, and unclaimed overtime are identified by eye, creating a high risk of errors passing through unchecked.
• Manually entering approved figures into Gusto (Step 8, ~30 min per cycle): After approval, the Finance Manager re-keys all finalised data into Gusto by hand. This duplication step adds time, introduces transcription risk, and has no automated audit trail for last-minute corrections.

02What changes after automation

Three agents handle the end-to-end payroll workflow once the pay period closes. The Timesheet Collection Agent pulls hours from Deputy and chases any missing submissions automatically. The Reconciliation and Calculation Agent compares hours against the schedule, applies leave and deduction rules, and builds the payroll summary in Google Sheets. The Approval and Submission Agent routes the summary to the business owner for a single approval action, then pushes confirmed data directly to Gusto and posts a confirmation to Slack. Your Finance Manager's only required actions are resolving genuine exceptions flagged in Slack and confirming any edge cases before the approval email is sent. The business owner retains the approval decision point as a deliberate human control step. Nothing is submitted to Gusto without that approval.

06Assumptions log

These numbers reflect a bi-weekly payroll cycle for a Finance Manager at $30/hour. If your volume or rates change, the savings scale directly. For every additional employee added to payroll, the reconciliation and data-entry time increases under the manual process but remains flat under automation, widening the saving further. If you move from bi-weekly to weekly payroll (52 cycles/year), the annual hours saved would approximately double to 470 hours and the annual staff cost saving would rise to around $14,100, with the same one-off build cost and platform fee. Conversely, if your Finance Manager rate is higher than $30/hour, every figure in the savings column increases proportionally. The break-even point remains at or before month 5 across all realistic volume scenarios at this pay frequency.
