200 pages, checked one by one

Comparing POs and invoices side by side — part numbers, quantities, amounts, line by line. 2 hours a day. Every day.

Double-check = 2 people, 4 hours total

Person #1 spends 2 hours checking. But there's no record of "what was checked," so person #2 starts over from scratch.

And you still miss things

"M10 Bolt" vs "M-10 Bolt." Same product, different notation — missed. Human eyes have limits.

Auto-rotate, group, and reconcile — all by AI

Rotated PDFs? Auto-corrected. 200 pages matched by PO number? Auto-grouped. Then items reconciled one by one. Every comparison is visualized with beams showing what was matched.

02

That's why you don't need a first-pass checker

With human double-checks, there's no record of "what was checked and how." So the second checker starts over. With AI, every comparison is traced — just hit Enter. 2 people × 4 hours → 1 person × 10 minutes.

Why Totsugo

Handle thepaperwork the field actually uses, not the cleaned-up version

The forms that ERPs, RPAs, and general-purpose AIs choke on — Totsugo runs them as-is, with no setup.

突合.com の照合画面: AIが2つのPDFをビームで結びながら全項目を自動チェック
📠

OCR built for FAX & handwriting

Faxed POs, Japanese PDFs with handwritten edits — drop them in directly. No re-typing, no clean-up step before processing.

🧠

Semantic similarity matching

"M10 Bolt" vs "M-10 Bolt", "Stainless" vs "SUS304". The AI understands when two strings refer to the same thing, even when a literal match would fail.

No ERP or RPA replacement needed

Keep your current workflow and forms. Just drag the PDFs into a browser. No ERP migration, no RPA scenarios — live in 30 minutes from account creation.

Use Cases

Wherever two documents needline-by-line comparison

Manufacturing, construction, leasing, wholesale, trading. Anywhere humans currently scan two stacks of paper side by side, Totsugo fits in.

Case Study

How Nabel cutorder-check work in half

Nabel — a 199-person bellows manufacturer in Mie, Japan with four overseas sites — was reconciling roughly 100 × 100 PDFs every day by hand. Totsugo took over the first pass.

FAQ

Frequently Asked Questions

No. General-purpose AI is great at "summarize this PDF," but it can't "reconcile 200 pages of POs with 200 pages of invoices, item by item." Two reasons: (1) Page limit: general AI can't process long documents at once — it forgets along the way. (2) Structure: accurately reading which cell is which item from a PDF layout requires a specialized engine. That's what "M10 Bolt" vs "M-10 Bolt" matching needs. Totsugo is purpose-built for document reconciliation.
Invoices, purchase orders, receipts, delivery notes — virtually all standard business documents. AI understands even custom layouts.
No. Just upload the PDFs you already use. No format changes or system integrations required.
