Invoice processing software that admits when it is unsure
The free plan processes 25 invoices a month with unlimited users, takes no credit card and does not expire. You get your own intake address at the end of setup.
Capture, extraction, and the part everyone skips
A processing system that returns a confidently wrong total is worse than one that asks a question. Calibration is the feature.
Invoice processing software has three jobs. Capture the document in a form the system can work with. Extract the fields — vendor, number, dates, totals, tax, line items — without a person typing them. And decide which of those extractions a human needs to look at. The third job is the one that determines whether the other two save you anything.
Consider the arithmetic. If a system processes a thousand invoices at 95% field accuracy and cannot tell you which 5% it got wrong, you have to check all thousand, and you have saved nothing but typing. If the same system can hand you the eighty documents it is unsure about, you check eighty. The useful measurement is not accuracy, it is whether the confidence signal is honest.
This is why InletAP scores confidence per field rather than per document. A document with a 96% total and a 51% PO number is not "84% confident" — it is confident about one thing and unsure about another, and collapsing that into a single number throws away exactly the information you need. Each field also exposes the text it was read from, so verifying a value is a glance rather than a hunt through the PDF.
Some conditions bypass the score entirely and always route to a person: a vendor that has never been mapped, a document a rule has quarantined, or line items that do not sum to the stated total. That last one catches a specific and expensive failure — an extraction that is internally inconsistent but individually plausible on every field.
Capabilities
What the extraction layer does
Reads what vendors actually send
PDFs, scans, phone photographs, Office documents, and invoices typed into the email body with no attachment. Attachments are parsed out of the MIME structure on the server.
Confidence per field
Vendor, number, dates, totals, tax and line items each carry their own score. You set the threshold that decides what reaches a human.
Extraction evidence
“Why this value?” shows the text a field was read from, so verifying an extraction does not mean searching the document yourself.
Internal consistency checks
Line items are totaled and compared against the stated total. A variance is named on the document rather than discovered at close.
Review built for correction speed
The rendered document and the editable fields on one screen, with zoom and page navigation, a sticky action bar, and keyboard flow that survives a long queue.
Multi-invoice emails
One email carrying several invoices produces several documents, each extracted and metered separately, rather than one blob someone has to split by hand.
Why this one
What to actually check when comparing invoice processing tools
- Is confidence reported per field, or one score for the whole document?
- Can you see the evidence a value was read from, without leaving the screen?
- Are internally inconsistent extractions detected, or only individually implausible ones?
- What routes to a human regardless of score — unmapped vendors, quarantined files, total mismatches?
- Are your corrections tracked against the model's proposal, so you can see which vendors need a rule?
- Does it handle an email carrying several invoices as several documents?
- Can you test it on your own vendors' documents before paying, or only on a demo dataset?
Pricing
Test it on your own vendors first
Prices are in US dollars and exclude sales tax, which is added where it applies.
Paid plans renew automatically at the price shown — every month, or every 12 months on annual billing — until you cancel. Cancel any time in billing settings: the next renewal stops and you keep the period you have already paid for.
