Confidence scores explained
What confidence scores mean, how they're calculated, and when to trust them.
Every extracted field in InvoiceFlow has a confidence score. This tells you how certain the AI was about that value.
What the scores mean
| Badge | Confidence | What to do |
|---|---|---|
| Green | High | Usually correct — spot-check if the invoice is high-value |
| Yellow | Medium | Worth a quick look before exporting |
| Red | Low / Failed validation | Check and correct before exporting |
How confidence is calculated
Confidence is based on two things:
- Extraction quality — how clearly the AI could read the field from the PDF.
- Validation rules — InvoiceFlow checks that the extracted data is internally consistent:
- Subtotal + Tax should equal Total
- Invoice date should not be in the future
- Currency code should be a recognized ISO code
- Line item amounts should match quantity × unit price
If a validation rule fails, the affected fields are flagged with a red badge.
When to trust high-confidence fields
High-confidence fields on standard invoices from established vendors are almost always correct. You can safely skim these and focus your review time on yellow and red fields.
When to always verify
- First invoice from a new vendor
- Invoices with unusual layouts
- Scanned or photographed PDFs (not digital exports)
- High-value invoices regardless of confidence
