Invoices from Emails

Automatically collect invoices from your email accounts with secure SMTP and Google integration

How it works

Invoice Radar finds invoices across all your connected email accounts and displays them in a unified inbox. When you review an invoice, you have two options:

Accept a single invoice - Approve this invoice without any future automation
Trust the seller - Automatically accept all future invoices from this sender

This gives you complete control over which companies you trust for automatic collection.

Connecting your email accounts

To set up your unified inbox, you need to connect your email accounts to Invoice Radar. You can connect your email accounts using SMTP or OAuth.

SMTP connection works with any email provider (Gmail, Outlook, Yahoo, or your business email). It connects directly to your email server just like any email app on your phone or computer. Your emails stay private and are processed entirely on your device.

You can sign in with Google to connect to your email. You'll authenticate directly with Google, and you can revoke access anytime from your Google account settings. The authentication happens directly between the app and Google with no server in between, ensuring there's no way for us to read your email.

You can connect your Microsoft account with secure OAuth authentication. The connection is made directly between the app and Microsoft, ensuring your email data never passes through our servers.

Your email stays private

All email scanning happens locally on your computer. Invoice Radar only saves the invoice attachments you approve - your actual emails are never stored or transmitted anywhere. Connections to your email provider use TLS/SSL encryption, just like any secure email client.

When using OAuth for Google or Microsoft, the authentication happens directly between the app and the email provider, meaning no data passes through our servers.

Automatic downloads from payment providers

Some companies like Paddle and SumUp send you email notifications with download links instead of attaching the actual invoice PDF. Invoice Radar handles this automatically.

When you receive a Paddle invoice notification, Invoice Radar will detect it, visit the Paddle portal using the link in your email, and download the actual PDF for you. SumUp receipts work the same way.

More payment providers will be supported in the future.

Configuration Options

You can customize how Invoice Radar scans your email:

Folder Selection - Scan specific folders like "Inbox" or "Receipts" instead of all folders
Email Address Filtering - Filter by recipient address when multiple emails forward to the same inbox (e.g., billing@company.com)

FAQ

Microsoft: "Needs admin approval" error

If you're using Microsoft 365 or Outlook with a business or organization account, you might see a "Needs admin approval" error when trying to connect your email. This happens because your organization's IT administrator needs to approve Invoice Radar before employees can use it.

Solution for IT administrators:

To approve Invoice Radar for your organization, an administrator needs to grant consent by visiting this link:

https://login.microsoftonline.com/common/adminconsent?client_id=7e59d229-c9e5-44da-9199-ef6c2f94b171&redirect_uri=https://invoiceradar.com/microsoft/admin-consent/success&scope=https://graph.microsoft.com/.default

After the administrator completes the approval process, all users in the organization will be able to connect their Microsoft email accounts to Invoice Radar.

What permissions are requested:

offline_access - Allows the app to maintain access without requiring frequent re-authentication
email - Read your email address
openid - Sign you in and read your basic profile
IMAP.AccessAsUser.All - Read-only access to your mailbox via IMAP to scan for invoices
