Reading and checking documents automatically
Extraction is the easy half. Knowing when the model is unsure is what makes it usable.
Automated document reading works well when it is designed around its own uncertainty — routing what it is not sure about to a person instead of guessing.
Typical timeline: Pilot in 6–8 weeks
Confidence decides the path
These are the signs this is worth doing
If several of these are true, this is usually where the fastest return sits.
Document extraction has improved sharply. On a reasonable-quality scan of a structured document, modern models read fields accurately enough to be genuinely useful, including on formats they have not been trained on specifically.
That is not the interesting part. The interesting part is that accuracy is never total, and a system that quietly gets three percent of invoices wrong is worse than one that gets none of them — because nobody knows which three percent.
Designed around uncertainty
The design principle is that every extracted field carries a confidence, and the system is explicit about what it is unsure of rather than presenting everything with equal authority.
High-confidence extractions that also reconcile against a system record — an invoice matching an open purchase order on supplier, amount, and line items — post automatically. Anything below the threshold, or anything that does not reconcile, goes to a review queue where a person sees the document and the extracted values side by side, with uncertain fields highlighted. Correcting one is two clicks, not re-keying the document.
Corrections feed back, so the fields a person keeps fixing are the ones that improve. The straight-through rate rises over time instead of being fixed at whatever it was on day one.
What a realistic deployment looks like
- Documents ingested from email, upload, or a scanner without changing how suppliers send them.
- Extraction with per-field confidence, not a single overall score.
- Automatic reconciliation against POs, GRNs, or master records where they exist.
- Straight-through posting only where confidence and reconciliation both pass.
- A review queue showing the document beside the extracted values, uncertain fields flagged.
- Reporting on straight-through rate and correction patterns, so you can see it improving.
What to expect
Honest ranges. Your documents and their quality decide where you land.
Structured, good quality
Consistent supplier invoices, clean scans or native PDFs: a high straight-through rate is achievable, and most of the remainder are genuine exceptions worth a person's attention anyway.
Mixed formats
Many suppliers, varying layouts: a solid majority processed automatically, with the rest reviewed quickly rather than keyed from scratch.
Poor scans, handwriting
Faxed, photographed, or handwritten documents: extraction still helps, but as an assistance layer rather than as automation. We will say so before you buy it.
A system that says 'I am not sure about this one' is worth more than a system that is confidently wrong at a rate nobody is measuring.
We would rather tell you now than three weeks into a project. This work is usually the wrong call if any of the following describes you.
- Low document volumes. Below a certain throughput a person is simply cheaper, and we will do that arithmetic with you.
- Documents that are almost all poor-quality photographs or handwriting — expect assistance, not automation.
- Processes where every document needs human judgement anyway. Extraction saves keying; it does not save deciding.
The systems involved
We integrate rather than replace wherever it makes sense. These are the systems this work most commonly touches.
Document verification — questions we get asked
How accurate is it?
It depends on document quality and consistency, and any vendor quoting a single number without seeing your documents is guessing. We run a sample of your real documents through before scoping, so the expectation is based on your paperwork rather than a benchmark.
What happens to the ones it gets wrong?
They should not reach you as errors. Low-confidence or non-reconciling extractions go to review before posting — the design goal is that mistakes are caught by the confidence threshold rather than by your finance team.
Do suppliers have to change how they send documents?
No. Asking suppliers to change format is the most common reason these projects stall. The system takes what arrives, in whatever form it arrives.

Export documentation that generates itself
Export paperwork is largely the same data in many shapes. Generating it from one record removes both the typing and the inconsistencies that hold up shipments.

Identity verification is a solved problem technically. What determines whether it is done well is what you store afterwards, and what you deliberately do not.
