What This Workflow Does
This automation transforms the tedious, error-prone process of creating job offer letters into a streamlined AI-powered workflow. HR teams spend countless hours drafting customized offer letters, verifying details, and chasing approvals - this template eliminates those manual tasks while improving accuracy and compliance.
The system generates polished, legally-compliant offer letters in seconds by combining candidate data with your company's approved templates. OpenAI's natural language processing ensures each letter maintains proper tone and includes all required elements before routing for approval through Slack and final delivery via Gmail.
How It Works
1. Trigger with candidate data
The workflow initiates when new hiring data enters your system - either through manual entry, ATS integration, or spreadsheet upload. Essential details like candidate name, position, salary, and start date are captured.
2. AI letter generation
OpenAI processes the candidate data alongside your company's approved offer templates to generate a perfectly formatted letter. The AI ensures consistent branding, proper legal language, and accurate compensation details.
3. Automated verification
Before routing for approval, the system performs quality checks: verifying numerical accuracy, flagging missing information, and comparing against company compensation bands. Any discrepancies trigger alerts for HR review.
4. Slack approval workflow
The draft letter posts to designated Slack channels with interactive approval buttons. Managers can review, request changes, or approve with one click - eliminating email chains and version control issues.
5. Gmail delivery
Once approved, the system sends the finalized offer letter as a properly formatted email attachment through Gmail, with tracking to confirm the candidate received it. All documents are automatically archived.
