What This Workflow Does

This automation eliminates the tedious task of manually entering receipt data by automatically processing receipt images uploaded to Google Drive. When you drop a new receipt into a monitored folder, the workflow extracts vendor name, date, itemized purchases, and total amount using AI, logs everything to a Google Sheet, and sends you an email confirmation with a formatted summary.

Key Benefits

Save time: No more manual data entry from receipts
Reduce errors: AI-powered extraction ensures accuracy
Stay organized: All expense data automatically tracked in one spreadsheet
Get notified: Instant email confirmation when receipts are processed

Common Use Cases

Personal expense tracking and budgeting
Small business accounting and bookkeeping
Reimbursement documentation
Tax preparation record-keeping

Setup Requirements

Accounts needed:

Google Drive account (for receipt storage)
OpenAI account (for AI-powered data extraction)
Google Sheets account (for data logging)
Gmail account (for notifications)

Configuration steps:

Google Drive: Connect your account and select the folder where you'll upload receipts
Google Sheets: Make a copy of the template spreadsheet (link in workflow notes) to your own account and update the Sheet ID in the workflow
Email recipient: Change the notification email address to your own
AI model: The workflow uses GPT-4-mini by default, but you can select a different OpenAI model based on your accuracy and cost preferences

The AI Agent is configured to extract data in a strict JSON format with fields for vendor, date (converted to DD/MM/YYYY), itemized purchases, and total amount.

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.
