Assignee Payroll Calculations
Scans completed tasks for billable hours, calculates pay using stored hourly rates, and updates a Google Sheet with final amounts.
ops and IT teamsfounders and execs
What it does
You get paid accurately for every completed task as this agent scans your logs, cross-references your hourly rates in Google Sheets, and automatically updates your final amounts without manual calculation.
Step by step
- Configure the Dart trigger to poll the target board at a fixed interval for completed tasks.
- Define the schema for time logs and assignee rates in the initial Google Sheets template.
- Implement the code step to fetch data from the trigger output and format it for the LLM prompt.
Where the LLM does the work
- Use Google Gemini to parse unstructured task descriptions and extract billable hours accurately.
- Have the model cross-reference extracted hours with specific assignee rate cards in the spreadsheet.
- Let the LLM generate the final summary row including calculated totals before writing back to Sheets.
Watch out for
Rate changes mid-cycle can skew calculations so lock rates at the start of each payroll period.
Ambiguous task descriptions may lead to incorrect hour extraction so add validation steps in the code layer.
Google Sheets API quotas can be exceeded by large batches so implement chunked writes for updates.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Assignee Payroll Calculations: Scans completed tasks for billable hours, calculates pay using stored hourly rates, and updates a Google Sheet with final amounts. ## Specification - What it does: You get paid accurately for every completed task as this agent scans your logs, cross-references your hourly rates in Google Sheets, and automatically updates your final amounts without manual calculation. - Trigger: On a schedule (Scheduled · weekly) - Autonomy: Fully hands-off - Expected setup effort: about an afternoon - Tools/services involved: - Dart: Time tracking and task data source - Google Sheets: Storing assignee rates and payroll results - Code: Processing logic and calculations - Google Gemini Chat Model: AI time tracking and assignee scanning ## Known pitfalls, handle each one explicitly in your implementation 1. Rate changes mid-cycle can skew calculations so lock rates at the start of each payroll period. 2. Ambiguous task descriptions may lead to incorrect hour extraction so add validation steps in the code layer. 3. Google Sheets API quotas can be exceeded by large batches so implement chunked writes for updates. ## Reference implementation https://n8n.io/workflows/11257 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Project Management than Dart?
Yes. Dart is only the example project management in this recipe. The same flow works with Asana, Awork, ClickUp and Clockify. Swap the project management connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for Ops-IT teams who need one more recurring task off a human's plate.
Founders and execs get the same output without having to ask someone else to run it.
