Consolidate and report monthly financial documents using Google Drive and Slack

🎯 Description

Streamline your month-end accounting processes with this enterprise-grade automation designed to aggregate, validate, and merge fragmented financial documents into a single, professional reporting bundle. This workflow transforms manual document chaos into a structured, touchless system using Google Drive and Slack.

✨ How to achieve automated document consolidation

You can achieve a fully autonomous financial reporting cycle by using the available tools to:

1. List and scan folders — Automatically retrieve all documents from a designated Google Drive folder at the end of each month.
2. Validate file formats — Use an IF Node to ensure only PDF documents (invoices, receipts, statements) are processed, preventing workflow crashes from incompatible file types.
3. Aggregate binary data — Gather separate file streams into a unified data array using the Aggregate Node to ensure stable processing for the merge engine.
4. Merge into master reports — Utilize the HTML to PDF engine to consolidate individual files into one "Monthly Finance Pack" with professional naming conventions.
5. Secure and archive — Upload the consolidated master file back to a secure archive folder in Google Drive.
6. Notify the team — Send a real-time Slack alert with the final filename, ensuring the accounting team knows exactly when the report is ready.

💡 Key features

Intelligent filtering and validation
The workflow auto-detects MIME types to filter out non-PDF noise and system files. This ensures a consistent input for the merge engine and prevents processing errors.

Advanced data aggregation
By utilizing the Aggregate Node, the workflow handles multiple binary files simultaneously. This architecture prevents the "looping errors" common in basic PDF workflows and maintains document order during the merge process.

Dynamic time-stamping with Luxon
A critical technical feature of this template is the use of Luxon expressions for professional document naming. By utilizing {{ $now.setZone('America/New_York').toFormat('MMMM yyyy') }} within the Slack and upload nodes, the workflow automatically generates accurate timestamps. This eliminates manual renaming and ensures your archives are perfectly organized by month and year.
