I’ve automated 90% of my payroll work at an engineering firm. I use Claude Code to write Python scripts that pull timesheets from our ERP, Deltek Ajera. I check the data for oddities and, once everything looks right, push the timesheets into our HRIS, Paycom, through its API. I also have a script that parses and compares the preliminary payroll register with the timesheet data. Once I’m satisfied with the results, I can submit payroll. After payroll, my scripts create all the benefits upload files I used to create by hand. The spreadsheets I relied on for years are no longer necessary. Do I even need a spreadsheet anymore? Step-by-step: 1. I use Claude Code to write Python scripts for the payroll process. 2. I pull timesheets from Deltek Ajera, our ERP. 3. I check the timesheets for oddities. 4. Once the data looks right, I push the timesheets into Paycom, our HRIS, through its API. 5. I parse and compare the preliminary payroll register with the timesheet data. 6. Once I’m satisfied with the comparison, I submit payroll. 7. After payroll, I run scripts that create the benefits upload files I previously created by hand.
