Best Invoice OCR Software8 tools. Same 3 invoices.

We are testing 8 tools to find the best OCR software for invoice processing. Each tool gets the same clean PDF, handwritten invoice, and older scan. Results are pending.

Verdict

No verdict yet

No verdict yet. We have not run the full test.

We have locked the test method. We will publish results only after all 8 tools have processed the same 3 invoices and we have checked every output against manually reviewed ground-truth CSV files.

01 / Test corpus

1 baseline. 2 limit tests.

Three invoices cannot prove universal accuracy. They can show whether a tool handles the easy case. They can also show how it fails on handwriting and an older scan.

Source pending

Baseline

Clean digital baseline

A native or high-quality digital PDF. It has a clear header and multiple line items.

The baseline. Every invoice parser should handle this before the documents get difficult.

Source pending

Handwriting

Handwritten limit test

A real handwritten invoice. Labels, numbers, spacing, and table structure vary across the page.

The first limit test. It checks whether a tool reads handwriting without inventing fields or rows.

Source pending

Archive

Older-invoice limit test

An older invoice with faded print, an unusual layout, and scan artefacts.

The second limit test. It checks what survives when contrast and document structure have degraded.

02 / Comparison ledger

8 tools. 0 scores so far.

We have not run the full controlled test. Every row stays blank until we check its output against the same ground-truth files. We will record signup, price barriers, exports, processing time, and published file-retention claims on the test date.

03 / Scoring protocol

Count correct fields. Publish every miss.

We normalise harmless formatting differences. We count wrong values, missing rows, merged items, and invented data as failures. We will not hide those failures inside one weighted winner score.

The 2 published accuracy measures

header accuracy = correct expected fields / expected fields

line-item accuracy = correct expected cells / expected cells

Ownership disclosure

We built one of the tools. That matters.

Disclosure: Invaritech owns one of the 8 tools in this comparison. We will score it with the same files and rules. We will publish its misses, product limits, and any access problems.

No vendor pays to appear. We use no affiliate links. We will tie every score and verdict to the published output.

Limitations

3 invoices can expose failures. They cannot prove universal accuracy.

This is a small, difficult test. It covers 3 disclosed documents. It does not cover every language, industry, layout, or paid product configuration.
