Line math
Quantity × unit price is checked on every line, and the lines are added up against the subtotal. A line that is off says by how much.
Invoice and bill capture for finance teams
Every bill read to the line and checked to the cent. Approved before it reaches your books.
Vendor, line items, tax and totals are read from PDFs, scans and phone photos. Line math, subtotal + tax and possible duplicates are checked, and every flag shows its reason. Nothing posts to QuickBooks Online, Xero or Zoho Books without an approval.
Up to 3 invoices a day without signup. No card required.

Inside the reviewSample data · annotated product screenshot
18,926.20 − 18,338.80 = 587.40. The stated total does not reconcile with the extracted subtotal and tax. Check it against the source.
Winter blend surcharge appears in a line item and the summary. A reviewer needs to check whether it was counted twice; this is a flag, not a deletion.
Who it is for
For the people accountable for the books.
Accounting firms
Many clients in one workspace, each with its own email-in address. Staff review the flagged bills, not every bill.
See how it fitsBookkeepers
Monthly bill entry for clients: every line read, the totals checked, then pushed to QuickBooks Online or exported.
See how it fitsAP teams and controllers
Approval chains, duplicate checks and a recorded history of who approved what, and when.

For owners doing their own books. Supplier bills checked before they reach your books, 25 a month free.
See how it fitsFreight and logistics
Costs tagged to trip numbers, each invoice kept in the currency it was billed, handwritten slips read.

What it checks
The arithmetic, checked on every bill. The reason, shown on every flag.
Reading gets the figures off the page. The checks test whether those figures agree with each other. The first three run on every plan, Free included.
Subtotal + tax = total
Subtotal − discount + shipping + fees + tax must equal the stated total. A mismatch is flagged with the exact difference, like the $587.40 above.
Duplicates
Each new bill is compared with every invoice your workspace received in the last 400 days, on vendor, invoice number, amount and date, near matches included. Bills that state different invoice numbers are not grouped. Nothing is removed without your decision.
Unusual amounts
Team and Scale
A bill at twice or more, or a third or less, of that vendor’s average for the same client and currency is listed for a second look.
Measured, and published
In our own benchmark of 181 synthetic test documents, run through live production on 3 October 2026, all 5 invoices whose printed figures did not add up were flagged. 2 of the 172 that did add up were flagged as well: both were badly blurred photos.
A record of every decision
Approvals, rejections and corrections are recorded with who and when. Editing a money field on an approved invoice withdraws the approval, so the bill is approved again before it is pushed.
Line items on every plan
Description, quantity, unit price and amount, for every line, on every plan including Free. Tax is read per rate, so a bill with two VAT rates keeps both.

An invoice. A mismatch. A spreadsheet.
Open a sample invoice, see the line that doesn't add up, and download it as Excel. It uses fictional data and never posts to your books.

Keep your books. Change the data entry.
Connect one QuickBooks Online, Xero or Zoho Books company per workspace, review the extracted data, then push approved bills. Pushes are on paid plans and the trial; CSV and Excel export are on every plan.
QuickBooks Online bills can carry VAT on your own QuickBooks tax codes. Xero and Zoho Books pushes do not set tax codes yet.

For freight & logistics
Freight paperwork, costed to the trip.
Freight operators tag a trip number to a whole invoice or to a single line, keep each cost in the currency it was billed, and send handwritten fuel slips through their own lane. Trip numbers can be added after approval, when the paperwork arrives weeks after the load.
Matching a carrier's invoice to an agreed rate is not available yet.

A few practical questions.
What exactly does the arithmetic check compare?
Three things: quantity × unit price against each line amount, the lines against the subtotal, and subtotal − discount + shipping + fees + tax against the stated total. A mismatch is flagged with the difference and the figures behind it, and lowers that invoice’s confidence. The reviewer decides what happens next.
Are line items extracted on the free plan?
Yes. Line items are extracted on every plan, Free included, and the arithmetic and duplicate checks run on every plan. Paid plans add the push to QuickBooks Online, Xero or Zoho Books.
Do I need to replace my accounting system?
No. Keep QuickBooks Online, Xero or Zoho Books. Direct sync is available on paid plans and during the trial; CSV and Excel export are included on every plan.
What happens after the trial?
Start with a 14-day trial and 50 invoices, without a card. Then continue on Free with 25 invoices per month and CSV / Excel export. You are charged only if you choose a paid subscription.
Can I see it before uploading company documents?
Yes. Explore the guided sample with fictional invoice data. It demonstrates the review workflow without creating an account, sending a document for extraction or connecting your books.
