Timesheet Collection and Approval
[YourCompany.com] · HR Department · Prepared by FullSpec · [Today's Date]
This document sets out the financial case for automating your timesheet collection and approval process. It translates the hours your HR Administrator spends each pay cycle into an annual dollar cost, shows what that figure drops to after automation, and gives you a clear payback timeline. FullSpec handles the entire build, integration, and launch. Your role is to review the assumptions below, confirm the figures that reflect your situation, and decide whether to proceed.
01What the current process is costing you
6 hrs/week
Staff time lost every week
HR Administrator across 10 manual steps per pay cycle
$9,360/year
Annual staff cost of this process
Based on $30/hr fully loaded rate, 52 weeks
1 to 3 days
Current timesheet turnaround
vs same-day benchmark with automation in place
The three highest-friction steps in your current process are the ones that consume the most time and carry the highest risk of derailing the pay cycle entirely. Each one is predictable, repeated every pay period, and entirely solvable with the right automation logic.
- Consolidate Hours into Master Sheet (Step 4, 40 minutes per cycle): HR copies submitted hours from each individual employee into the master Google Sheet by hand. The failure mode is data entry errors introduced during transcription, and the step cannot start until all submissions are in, creating a hard bottleneck at the centre of the cycle.
- Chase Manager Approvals (Step 7, 25 minutes per cycle): HR follows up individually with each manager who has not responded by the internal deadline, via email or Slack. The failure mode is a single slow manager holding up the entire payroll run, with no automatic escalation and no audit trail of who was chased when.
- Enter Approved Hours into Payroll System (Step 9, 35 minutes per cycle): HR re-keys finalised hours from the master sheet into Xero or Gusto, employee by employee. The failure mode is 3 to 5 data entry errors per cycle that either cause a rejected sync or result in an incorrect pay amount being processed.

02What changes after automation
Once the three agents are live, the entire collection, chasing, approval, and payroll sync cycle runs automatically from the moment the pay period closes. The Collection Agent identifies missing submissions and sends personalised reminders without anyone in HR lifting a finger. The Approval Agent routes requests to the correct managers and escalates automatically if they do not respond within the set window. The Payroll Sync Agent transfers clean, approved hours directly into Xero via API and confirms the upload in Slack. One decision point remains in human hands: if an entry falls outside the agreed validation thresholds, the HR Administrator reviews the flagged row and confirms or corrects it. That single review step, typically around 15 to 20 minutes, is the only recurring task HR performs in the new process.

$3,884 + $3,200 build = $4,484 total Year 1 outlay
Already using some of these tools? If Google Workspace (Forms, Sheets, Gmail) and Xero are already in your stack, your incremental spend is limited to the workflow automation platform at $588/year and the Slack Pro seat at $96/year, totalling $684/year in new recurring costs. That reduces the net outlay to the FullSpec build cost of $3,200 plus $684 in Year 1 tool costs, bringing total Year 1 spend to $3,884 rather than a higher baseline. Confirm your existing subscriptions with your team before finalising the numbers.

FullSpec estimate (Year 1: $5,476 + Year 2-3: $8,676 x 2)
These figures are based on information confirmed during your process mapping session and supplemented by FullSpec estimates where live data was not available. Any row marked 'FullSpec estimate' should be reviewed against your actual contracts and payroll records before the business case is presented internally. The numbers are conservative and do not include the cost of payroll errors, compliance risk from late submissions, or staff overtime during payroll-week pressure.
If your situation changes, the numbers scale predictably in both directions. If your team grows from 40 to 80 employees, the manual burden roughly doubles while the automated process handles the additional volume with no change in HR time, meaning the annual saving grows without a proportional increase in tool costs. If your HR Administrator's hourly rate is higher than $30, the payback period shortens because each hour saved is worth more. Conversely, if your pay cycle is monthly rather than weekly or fortnightly, the annual hours saved will be lower and the payback period will extend slightly beyond four months. FullSpec can rerun these figures with your confirmed inputs at any point before build begins. Contact the team at support@gofullspec.com to request an updated projection.
