⚡ 97 views · 🔬 Document Extraction & Analysis
Description
📘 Description
This automation streamlines developer billing and compliance tracking by integrating Jira, Gmail, and n8n into a single intelligent workflow. It fetches all project issues from Jira, calculates logged hours per team member, identifies missing time entries, and automatically generates professional invoice summaries — complete with text attachments — which are then emailed to each developer. The system ensures no time logs are missed, billing remains accurate, and finance teams receive transparent, auditable records — all without manual follow-ups.
⚙️ What This Workflow Does (Step-by-Step)
🟢 When Clicking ‘Execute Workflow’ Starts the entire billing and compliance cycle manually or on schedule.
📋 Fetch All Project Issues with Time Data Retrieves all Jira issues across projects, including:
- Time spent (seconds → hours)
- Assignee, project, sprint, and status info
- Priority and issue summaries
- This serves as the foundation for billing calculations and compliance checks.
📊 Aggregate Hours by Team Member Groups issues by assignee and calculates total hours logged per person. Outputs per-user data with:
- Name & email
- Total logged hours
- Full issue breakdown (status, sprint, priority)
- Forms the core dataset for both invoice creation and reminder logic.
⚠️ Identify Issues with Missing Time Logs Scans aggregated data to find issues where time = 0 hours. Generates HTML reminders with:
- Table of unlogged issues (key, summary, sprint, status)
- Personalized note urging time entry completion
- Only sends reminders to users who actually missed logs.
- Prevents manual follow-up and ensures billing accuracy.
💰 Generate Invoice Summary with Text Attachment Creates text-based invoice documents for each user with logged hours. Includes:
- Itemized issue breakdowns
- Hourly rate (default: $50/hr)
- Total hours & billing amount
- Auto-generated timestamp
- Exports invoices as text attachments (Invoice_{Assignee}.txt) in base64.
🔗 Combine Reminder & Invoice Data Streams Merges invoice data and reminder data into one unified stream, ensuring:
- All users (with or without logged hours) are processed
- Emails contain correct context and attachments
- Enables complete communication coverage in a single workflow.
🔧 Reconcile JSON & Binary Attachments
- Smartly merges JSON email metadata and binary invoice files post-merge.
- Handles complex data cases (missing binary or JSON) using fallback logic.
- Guarantees each email has a valid recipient and invoice attachment.
📧 Send Invoices & Reminders to Team Sends personalized emails to each developer with:
- Subject: project name
- Body: hours summary & reminder message
- Attachment: invoice text file (if available)
- Emails are automatically delivered via Gmail with audit trails.
