1.1 Workflow description

Title: Extract and structure invoice data with DocSumo and export to Excel
Workflow name: Extract and structure invoice data with DocSumo and export to Excel

Description

This workflow automates the extraction of structured data from invoices or similar documents using Docsumo's API. Users can upload a PDF via an n8n form trigger, which is then sent to Docsumo for processing and structured parsing. The workflow fetches key document metadata and all line items, reconstructs each invoice row with combined header and item details, and finally exports all results as an Excel file. Ideal for automating invoice data entry, reporting, or integrating with accounting systems.

How It Works

A user uploads a PDF document using the integrated n8n form trigger.
The workflow securely sends the document to Docsumo via REST API.
After uploading, it checks and retrieves the parsed document results.
Header information and table line items are extracted and mapped into structured records.
The complete result is exported as an Excel (.xls) file.

Setup Steps

Docsumo Account:
- Register and obtain your API key from Docsumo.
n8n Credentials Manager:
- Add your Docsumo API key as an HTTP header credential (never hardcode the key in the workflow).
Workflow Configuration:
- In the HTTP Request nodes, set the authentication to your saved Docsumo credentials.
- Update the file type or document type in the request (e.g., "type": "invoice") as needed for your use case.
Testing:
- Enable the workflow and use the built-in form to upload a sample invoice for extraction.

Features

Supports PDF uploads via n8n’s built-in form or via API/webhook extension.
Sends files directly to Docsumo for document data extraction using secure credentials.
Extracts invoice-level metadata (number, date, vendor, totals) and full line item tables.
Consolidates all data in easy-to-use Excel format for download or integration.
Modular node structure, easily extensible for further automation.

Prerequisites

Docsumo account with API access enabled.
n8n instance with form, HTTP Request, Code, and Excel/Convert to File nodes.
Working Docsumo API Key stored securely in n8n’s credential manager.

Example Use Cases

Scenario	Benefit
Invoice Automation	Extract line items and metadata rapidly
Receipts Processing	Parse and digitize business receipts
Bulk Bill Imports	Batch process bills for analytics

Notes

Credentials Security: Do not store your API key directly in HTTP Request nodes; always use n8n credentials manager.
Sticky Notes: The workflow includes sticky notes for setup, input, API call, extraction, and output steps to assist template users.
Custom Columns: You can customize header or line item extraction by editing the Code node as needed.

Send Stripe payment invoices with Gmail, Google Drive, and WhatsApp

## Quick overview This workflow triggers on successful Stripe payment events, generates and finalizes invoices, then formats and sends invoice details via Gmail, stores invoice PDFs in Google Drive, and notifies an admin through WhatsApp using Rapiwa. ## How it works 1. Triggers when Stripe reports a successful payment, invoice payment, or checkout session completion. 2. Checks whether the payment amount matches the amount received and, if it does not, calculates a payment summary for review. 3. Retrieves the Stripe customer and creates then finalizes a Stripe invoice configured to be sent with Net 30 terms. 4. Fetches invoices created since the event time, iterates through the results, and keeps only Stripe objects that are invoices. 5. Pulls Stripe checkout session line items and formats company, customer, totals, and a custom invoice number for messaging and file naming. 6. Emails the customer the invoice details and PDF link via Gmail, sends an admin WhatsApp alert via Rapiwa, downloads the PDF, and uploads it to Google Drive. ## Setup 1. Add Stripe API credentials, enable the Stripe webhook events used by the trigger, and copy the webhook URL into your Stripe dashboard. 2. Add Gmail OAuth2 credentials and confirm the workflow’s Gmail “send to” mapping matches the email field returned by your Stripe checkout session. 3. Add Google Drive OAuth2 credentials and set the target Drive folder in the Google Drive upload step. 4. Add Rapiwa API credentials and replace the placeholder WhatsApp number with your admin number. 5. Update the company identity, banking details, and any invoice terms (for example days until due) in the invoice formatting and Stripe invoice creation steps. ## Requirements - **Stripe API**: Connects to the Stripe account to listen for webhooks (`payment_intent.succeeded`, `checkout.session.completed`, etc.) and perform API operations (retrieve customers, create invoices, finalize invoices). - **Gmail OAuth2**: Used to send the generated invoice PDF and details to the customer. - *Google Drive OAuth2**: Used to upload and save the generated PDF invoices to a cloud storage folder. - **Rapiwa API**: Used to send WhatsApp notifications to the admin regarding order details and workflow status. ## Customization - Adjust invoice settings in the **Create Stripe Invoice** and **Finalize Invoice** nodes (e.g., due date, collection method, - Customize the customer email content in the **Email (Send Invoice)** node. - Update the **Invoice Save to Google Drive** node's `folderId` to store PDFs in a specific Google Drive folder. ## Additional info • Uses Stripe events for payment validation and invoice generation • Update company details in the **Format Invoice Data** node to match your business • Dynamically fetches purchased items from Stripe sessions • Validates payment amounts before processing invoices • Replace the placeholder WhatsApp number in the **Rapiwa** node with your admin number

Send escalating invoice reminders with Notion, Claude, Gmail and Telegram

## Quick overview This workflow runs every morning to pull unpaid invoices from a Notion database, calculates how overdue each one is, uses Anthropic Claude to draft an escalation-appropriate reminder, emails the client via Gmail, updates the invoice record in Notion, and alerts you in Telegram for high-risk late payments. ## How it works 1. Runs every day at 8:00 AM on a schedule. 2. Fetches all unpaid invoice pages from a Notion database and normalizes the key invoice fields into a flat structure. 3. Calculates days overdue from the due date, determines which reminder tier (1/2/3) is due based on thresholds and what was already sent, and skips invoices that are not yet due for the next escalation. 4. Uses Anthropic Claude to generate a subject line and message body that matches the escalation tier. 5. Sends the reminder email to the client via Gmail and updates the Notion page to record the latest reminder tier sent. 6. If the invoice reaches the final (tier 3) escalation, sends a Telegram message to the freelancer to flag the invoice as a payment risk. ## Setup 1. Create or choose a Notion invoice database with the properties referenced by the workflow (including Status, Due Date, Client Email, and Reminder Tier Sent) and paste the database ID into the Notion node configuration. 2. Add credentials for Notion, Anthropic (Claude), Gmail, and Telegram, and select them in their respective nodes. 3. Set your Telegram chat ID in the Telegram node and ensure your Notion Status values match the workflow filter (for example, invoices to remind are marked as “unpaid”).

Recover overdue invoices with GPT-4o-mini, Gmail, Google Sheets, and Slack

## Quick overview This workflow runs daily to read overdue invoices from Google Sheets, uses OpenAI (GPT-4o-mini) to draft personalized reminder emails and determine escalation level, sends emails via Gmail, posts Slack alerts for no-invoice runs or AI errors, and logs results back to Google Sheets. ## How it works 1. Runs every 24 hours on a schedule. 2. Reads rows from the “invoices” tab in Google Sheets and, if no invoice value is found, posts a “no overdue invoices” message to Slack. 3. For each invoice, sends the invoice details to OpenAI (GPT-4o-mini) to determine an escalation level, draft an HTML email, and recommend whether to escalate. 4. Parses the AI’s JSON response (falling back to a default reminder if parsing fails) and sends the recovery email to the client via Gmail. 5. If the AI recommends escalation, sends an internal escalation email via Gmail to the legal/AR team with invoice details and the AI summary. 6. Updates the original invoice row in Google Sheets with the escalation level and summary, then appends an audit row to the “Recovery sheet” tab including the email subject, summary, and sent message label ID. 7. If the AI step errors, posts an error alert to Slack and continues processing. ## Setup 1. Add Google Sheets OAuth2 credentials and replace YOUR_GOOGLE_SHEET_ID, ensuring the “invoices” and “Recovery sheet” tabs and columns (Invoice, Client, Email, Amount, Due Date, Days Overdue, Reminders Sent, plus row_number) match the workflow. 2. Add an OpenAI credential for the GPT-4o-mini model. 3. Add Gmail OAuth2 credentials and set the reply-to address ([email protected]) and escalation recipient ([email protected]) to your real emails. 4. Add Slack OAuth2 credentials, replace YOUR_SLACK_CHANNEL_ID, and choose the channel that should receive status and error alerts.
