2. Drag your files onto Drop invoices here, or click Select files. You can pick several files at once.
3. Each file shows its progress: Uploading…, Queued, Classifying… and then Auto-classified or Needs check.
4. Done? Close the window. Your invoices are listed under Costs.

Which files?

• PDF or images (such as JPG, PNG, WEBP, HEIC, BMP and TIFF).
• Up to 10 MB per file.
