For most small businesses the useful automation is not “an AI that does the invoices.” It is a sequence: the AI reads the document and pulls the fields out of it, checks what it read against your vendor list, your purchase orders and your approval threshold, and then a named person approves what actually posts to the books. The reading is the easy part. The checking is where the money is.
Before you evaluate any tool, sort last month’s pile into two stacks: files a computer generated, and pictures of paper. Text extraction reads the first stack and returns nothing on the second — a scan or a phone photo is an image with no text layer, and needs optical character recognition on top of everything else. Most tools in this category, ours included, quietly assume your invoices are digital. The ratio between those two stacks predicts your result better than any feature list will.
Three validations carry most of the value, and none of them are glamorous: is this a vendor we actually use, does it match what we ordered, and is it above the amount where a person has to decide. An extraction error is annoying — a wrong date, a transposed digit, somebody fixes it. A validation error is what costs money: the duplicate that arrived twice, the vendor you have never bought from, the amount that is ten times the usual.
Two deadlines are worth checking today. If you file ten or more information returns in a year — 1099s, W-2s and 1098s counted together, not ten of each — you must file them electronically; that threshold dropped from 250 per form type to 10 in aggregate for returns required to be filed on or after 1 January 2024, and the IRS runs a free portal for exactly this case. And if you invoice European customers, the invoice is becoming a regulated data format: France requires every business to be able to receive structured electronic invoices from 1 September 2026, with large and mid-sized companies also issuing them from that date and smaller companies from 1 September 2027, while Germany has required the ability to receive them since 1 January 2025.
However you buy, run it dry first. A sensible install logs what it would have posted instead of posting it, so you can run it alongside your existing process for a week and compare the two piles before anything reaches your accounting system. If a vendor will not let you do that, that is information about the vendor. Ask one more question while you are there: if extraction runs against a third-party API, your vendor and invoice data leaves your environment; if it can run against a model on your own hardware, it does not.
