Send seasonal WooCommerce sales trend reports to Slack and Google Sheets

WooCommerce Seasonal Sales Planning & Monitor → SET Pattern Compare → Slack

This workflow automatically aggregates sales data, calculates performance trends (Revenue & Orders) against previous months and years, identifies the top-selling SKU and sends a strictly formatted, professional summary report to Slack.

This workflow runs on a schedule (e.g., daily or weekly) to generate a snapshot of your business performance. It fetches sales data from your database or e-commerce platform, calculates growth percentages (vs. Month, vs. Year), formats the data into a clean JSON structure and sends a structured report to Slack without unnecessary clutter or emojis.

You receive:

• Automated comparison of Revenue & Order counts
• Trend analysis (Percentage change & directional trend)
• Identification of the Top Performing SKU
• A clean, professional Slack alert for team visibility

Ideal for management teams needing a quick, data-driven pulse check on store performance without manually running reports.

Quick Start – Implementation Steps

1. Add your Database or API Credentials (e.g., Postgres, Shopify, WooCommerce) in the data fetching nodes.
2. Connect your Slack account credentials and select the target channel.
3. Ensure your data source provides current, vsMonth and vsYear metrics (or use the calculation nodes provided).
4. Review the Slack Node to ensure the JSON block formatting matches your preference.
5. Activate the workflow — automated reporting begins instantly.

What It Does

This workflow automates the generation of your business trend report:

1. Trigger: Starts automatically based on a schedule (e.g., every morning at 8 AM).
2. Fetch Data: Retrieves raw sales numbers for the current period, previous month and previous year.
3. Process Trends: Calculates the percentage difference and determines the trend direction (Increase, Flat, Decrease).
4. Identify Top SKU: Sorts product sales to find the highest-performing item of the period.
5. Format Report: Constructs a strict JSON object containing:
   • Revenue (Current, vs Month, vs Year)
   • Orders (Current, vs Month, vs Year)
   • Top SKU Name
6. Send Slack Alert: Pushes a cleanly formatted message (using Block Kit or Markdown) to your team channel.

This ensures your team focuses on the numbers that matter, with zero manual effort.

Who’s It For

This workflow is ideal for:

• E-commerce Store Owners
• Sales & Marketing Managers
• Data Analysts
• Operations Teams
• Executive leadership requiring daily snapshots
• Teams preferring data-heavy, emoji-free reports

Requirements to Use This Workflow

To run this workflow, you need:

• n8n instance (cloud or self-hosted)
• Data Source (PostgreSQL, MySQL, Shopify, WooCommerce or Google Sheets)
• Slack workspace with API permissions (Webhook or Bot Token)
• Basic understanding of JSON structure for Slack Block Kit

How It Works

1. Scheduled Trigger – Initiates the workflow at a specific time.
2. Get Sales Data – Queries your backend to get the raw numbers.
3. Calculate Logic – Compares current numbers vs. historical data to generate percentages.
4. Create Report Object – Maps the values into a standardized JSON format (e.g., revenue.current, orders.vsYear).
5. Format Message – Converts the JSON object into a Slack-readable text block or UI block.
6. Send Notification – Posts the final report to Slack.

Setup Steps

1. Import the provided n8n JSON file.
2. Open the Data Fetch nodes and configure your database/API connection.
3. Ensure your query returns the necessary fields (Revenue Orders, SKU).
4. Verify the Format Data node is correctly mapping your variables to the JSON structure:
   • {{ $json["revenue"]["current"] }}
   • {{ $json["orders"]["vsMonth"]["percent"] }}
5. Connect Slack API credentials and choose your channel.
6. Run a test execution to verify the numbers appear correctly in Slack.
7. Activate the workflow — done!

How To Customize Nodes

Customize Report Metrics

Modify the Set/Calculation nodes:

• Add Average Order Value (AOV)
• Include Customer Acquisition Cost (CAC)
• Change the comparison period (e.g., vs Last Week instead of Month)

Customize Slack Layout

You can modify the JSON in the Slack node to:

• Use Block Kit for a table-like structure (columns for Revenue/Orders)
• Use Plain Text for a simple list view
• Add or remove bold formatting (*bold*)
• Add a "View Dashboard" button link

Customize Data Source

Replace the generic database node with:

• Shopify Node (Get Orders)
• WooCommerce Node (Get Sales Report)
• Stripe Node (Get Balance Transactions)
• Google Sheets (Read Row)

Add-Ons (Optional Enhancements)

You can extend this workflow to:

• Send reports to Email or Microsoft Teams in addition to Slack.
• Generate a PDF report using an HTML-to-PDF service.
• Save the daily snapshot into a "History" table in Airtable/Database.
• Add conditional alerts (e.g., @mention the CEO if Revenue drops by >20%).
• Integrate with OpenAI to write a qualitative analysis of the trends.

Use Case Examples

1. Morning Standup Report

Delivers key metrics to the team channel 15 minutes before the daily meeting.

2. Performance Monitoring

Quickly identifies if a new marketing campaign is driving order volume.

3. Inventory Awareness

Highlights the "Top SKU" so the warehouse team knows what is moving fast.

4. Executive Summaries

Provides leadership with a noise-free, "just the numbers" view of the business.

Troubleshooting Guide

Issue	Possible Cause	Solution
"N/A" in Trend	No historical data found	Ensure database has data for previous month/year
Slack formatting broken	Invalid JSON syntax	Check quotes and brackets in Slack node
Wrong Top SKU	Sorting logic incorrect	Verify the "Sort" node is ordering by Count DESC
Authentication Error	Slack token expired	Re-connect Slack credentials in n8n
Workflow not running	Schedule disabled	Toggle "Active" switch to ON
