Most operators land on one fix first. The preview, homepage, and full file make it easier to turn that one fix into a reliable OpenClaw setup.
Payroll is one of those tasks that's painfully repetitive, high-stakes, and just begging to be automated. I've set up payroll workflows for several small businesses on OpenClaw — here's exactly how I'd do it.
The Core Payroll Workflow
The basic flow: pull employee hours → calculate gross pay → apply deductions → generate pay stubs → log for tax purposes. OpenClaw handles all of this with the right config:
# In AGENTS.md
## Payroll Processing
On the 15th and last day of each month:
1. Read /workspace/payroll/employees.csv for rates, deductions, tax withholdings
2. Pull hours from /workspace/payroll/timesheets/YYYY-MM.csv
3. Calculate: gross = hours * rate, then apply tax rates
4. Net = gross - fed_tax - state_tax - benefits - other_deductions
5. Generate pay stub and email each employee
6. Log to /workspace/payroll/ledger/YYYY.csvSetting Up the Cron
openclaw cron add "0 9 15,28 * *" --name payroll-run \
--task "Run payroll for this period. Process all active employees in /workspace/payroll/employees.csv, calculate net pay using rates in /workspace/payroll/tax-rates.json, generate stubs, send via email. Log all transactions."Tax Calculation Config
// /workspace/payroll/tax-rates.json
{
"federal": {
"single": { "rate": 0.22, "standard_deduction": 13850 },
"married": { "rate": 0.22, "standard_deduction": 27700 }
},
"state": "CA",
"state_rate": 0.093,
"fica_employee": 0.0765
}Handling Edge Cases
Payroll always has edge cases — overtime, bonuses, new hires mid-period:
## Payroll Exceptions
Before processing payroll check /workspace/payroll/exceptions/current.md for:
- New hires: prorate first-period pay based on start date
- Terminations: issue final check within 3 days per state law
- Bonuses: separate line item with supplemental withholding rate
- Overtime: hours over 40/week get 1.5x rateYear-End Reporting
openclaw cron add "0 9 2 1 *" --name w2-prep \
--task "January 2: compile annual payroll summary from /workspace/payroll/ledger/. Calculate YTD totals per employee: gross wages, fed tax withheld, state tax withheld, SS wages, Medicare wages. Export W2-ready CSV."For more automation patterns, check the invoice automation guide and QuickBooks integration.

Frequently Asked Questions
Can OpenClaw handle multi-state payroll tax calculations?
Yes. Store each state's tax rates in your tax-rates.json file. For employees in different states, the agent looks up the correct rate by the employee's work location in your employees.csv.
How does OpenClaw handle overtime pay calculations?
Define your overtime rules in AGENTS.md: FLSA standard is 1.5x for hours over 40/week, but states like California have daily overtime rules. The agent applies the rule matching the employee's state.
Can OpenClaw generate actual pay stub PDFs?
Yes with the right tools connected. Integrate a PDF generation service or use a pay stub template. OpenClaw fills in the data, triggers PDF generation, and emails the result to each employee.
Is payroll automation with OpenClaw compliant with labor laws?
OpenClaw automates the calculations and communications — you're responsible for verifying tax rates are current. Treat it as an assistant that executes your payroll logic, not a certified payroll service.
