    Chicago, IL

    Ad platforms bill in round threshold charges with no invoice number, and freelancer invoices rarely share a template.

    The setup

    An invented Chicago business, built down to the chart of accounts

    The company and its vendors are made up. It still has its own QuickBooks company, its own local sales tax, and documents written the way this trade writes them.

    Its own email address, connected to DocStreamAI

    Nobody approved or corrected anything along the way. A document one of DocStreamAI's checks held for review stayed held, so every result is exactly what was read.

    Who sends the paperwork

    14 vendors in 8 trades, writing on 9 different layouts.

    The traps

    Where this paperwork goes wrong

    Ad platforms charge the card whenever spend crosses a threshold, so the amounts land on exact round values, there is no invoice number, and several charges from the same vendor on the same day is normal. Freelancer invoices are the opposite, and they rarely share a template.

    Three identical charges in one day

    Spend crossed the threshold three times. Same vendor, same amount, same date, and all three are real.

    Not in dollars

    A freelancer bills in euros. The amount reads correctly and the money is still wrong without the currency.

    A subscription settles the day it is issued. It is not overdue and should not be chased.

    A volume tier the page never shows. The vendor billed 399.00, and recalculating restates the invoice.

    The results

    How DocStreamAI handled this inbox

    Measured in two places. Inside DocStreamAI: what was read, what kind of document it is, whether it made it from the email, which vendor it belongs to and where it was categorized, each checked against the answer key written for every document. Then in QuickBooks: whether the record that landed matches.

    52 text PDFs from Wendlemarsh Creative Studio, the kind billing software makes. 51 reached extraction and were scored against their answer keys.

    * Line descriptions, quantities and unit prices count as lower severity and are left out of this figure. QuickBooks records each line by its amount, so a wrong quantity or unit price does not change what lands in the books. Counting them too: 92.2% (47 of 51).

    Scanned PDFs

    Scans, phone photos and faxes, on their own

    Reported apart from text PDFs because one part of handling them is still being built.

    33 scanned PDFs sent: office scans, phone photos, faxes and photocopies saved as PDF. 24 reached extraction and were scored.

    Scanned vendor statements kept out

    0 of 2

    Not recognised as statements yet. 1 of the 2 were posted as bills.

    Planned for a future update: picking up scanned PDFs that arrive alongside other attachments, and recognising a scanned vendor statement for what it is.

    * Line descriptions, quantities and unit prices count as lower severity and are left out of this figure. QuickBooks records each line by its amount, so a wrong quantity or unit price does not change what lands in the books. Counting them too: 87.5% (21 of 24).

    In QuickBooks

    What landed in the books

    The record in QuickBooks matches the document and what DocStreamAI read, per record type.
