From document to structured fields.
Supplier, identifiers, dates, line items, VAT and totals are extracted into a reviewable schema. Unsupported or ambiguous documents are not forced into an invoice result.

can hurt you.
Foldline extracts invoice fields, verifies what it can prove, and keeps source evidence next to anything that needs a human review. If extraction is uncertain, Foldline withholds the risk result instead of guessing.

How Foldline works
01Upload
Add a PDF or image privately.
02Extract
Foldline turns the invoice into structured fields.
03Gate
Extraction must be reliable before risk is calculated.
04Review
You see verified checks, evidence, or a clear needs-review state.
Proofline
Review only what can hurt you.
Extraction is only the first step. Foldline separates extraction uncertainty from business exceptions, keeps the original evidence beside the result, and refuses to turn parser uncertainty into a fake risk score.
- Every extracted value can keep its source snippet.
- Subtotal, VAT and line-item arithmetic are checked only when the required values are reliable.
- Duplicate detection matches invoice number with supplier identity to reduce false positives.

Total mismatch
Subtotal + VAT does not match the invoice total.

What the MVP does today
Invoice review first. Broader document workflows later.
The current product is intentionally narrow while the first real workflows are being validated.
Catch verified arithmetic and history problems.
Foldline checks invoice math and same-supplier duplicate invoice numbers. Optional fields such as PO references are not treated as errors unless a future workspace rule requires them.
No mystery score.
Uploads move through explicit processing states. A document is either reliably checked, needs human review, unsupported, or failed.

Security
Uploaded documents are not public files.
Foldline uses private storage, short-lived signed access and database policies to keep document access scoped to the right account and workflow.

Practical answers about what the current MVP does, where documents go, and what still requires human judgment.
Is Foldline just OCR?
No. Document conversion is only the parsing layer. Foldline adds structured fields, source evidence, a reliability gate, deterministic invoice checks and human review.
What happens if Foldline is not sure it read the invoice correctly?
It does not turn extraction uncertainty into a business-risk score. The document is marked as needing review, the uncertain fields remain editable beside the original, and risk stays uncalculated until the extraction is reliable enough or a person confirms the data.
Do I have to check every extracted field?
Not when the extraction passes the reliability gate. Proofline focuses attention on verified exceptions. If extraction itself is uncertain, Foldline makes that clear and asks for a human review instead of pretending the result is reliable.
Is a missing PO number automatically an error?
No. A PO reference is informational by default because not every invoice requires one. A future workspace rule can make it mandatory for a specific workflow.
How does duplicate detection work?
Foldline does not flag an invoice as a duplicate from the invoice number alone. The current check also requires the same supplier identity in the workspace.
Where are original documents stored?
Original documents are stored in a private Supabase Storage bucket. Browser access uses short-lived signed URLs rather than permanent public file links.
Does Foldline make accounting or tax decisions?
No. Foldline structures and checks document data. A person remains responsible for reviewing the result before relying on it.
Can I export the result?
Yes, but uncertain extraction must be reviewed first. Unsupported documents are not exported as invoices.
What document types are supported?
Invoice review is the current MVP path. Related documents can be stored in a review packet, while broader cross-document checks are still being tested and are not presented as a finished capability.
