BuchhaltungsButler

Overview

The BuchhaltungsButler integration automatically uploads your collected invoices to BuchhaltungsButler as inbound receipts (Eingangsbelege).

Requirements

• A BuchhaltungsButler account
• API credentials: Client ID, Secret, and Key

Setup

Getting your API credentials

1. Log in to your BuchhaltungsButler account
2. Follow the official API setup guide
3. Generate your API Client ID, Secret, and Key

Configuring in Invoice Radar

1. Open Invoice Radar and go to Settings → Export
2. Click Add destination and select BuchhaltungsButler
3. Enter your API credentials:
   • API Client ID
   • API Secret
   • API Key
4. Choose a start date:
   • All invoices - Export everything in your collection
   • From specific date - Only export invoices after the selected date
5. Enable the destination

How it works

When you export invoices to BuchhaltungsButler:

• Each invoice is created as an inbound receipt (Eingangsbeleg)
• The PDF is attached automatically
• Metadata (vendor, date, amount) is included

Rate limiting

BuchhaltungsButler's API is limited to 10 requests per minute. Invoice Radar automatically throttles bulk exports to stay within these limits. Large exports may take longer due to this restriction.

Exporting invoices

Bulk export

Click Export Now in the Export settings to sync all unsynced invoices. Progress is shown in real-time. Note that large batches are automatically throttled to respect API limits.

Individual export

Open any invoice in the document details panel to see its export status and manually trigger an export.

Troubleshooting

"Authentication failed" error

• Verify all three credentials (Client ID, Secret, Key) are correct
• Make sure you copied them without extra spaces
• Check that your API access hasn't been revoked

Exports taking a long time

• This is normal for large batches due to rate limiting (10 requests/minute)
• A batch of 100 invoices takes approximately 10 minutes

Invoices not appearing in BuchhaltungsButler

• Check that the destination is enabled
• Verify invoices meet the start date criteria
• Look for error messages in the export history

Security

• Your API credentials are encrypted and stored only on your device
• Invoices are sent directly to BuchhaltungsButler's API with no intermediary
• All connections use HTTPS/TLS encryption
