In most growing companies, someone opens a PDF, reads it, and types the same fields into the ERP. Purchase orders, supplier invoices, delivery notes, and customer forms all arrive this way. The work is slow, it is easy to get wrong, and it usually lands on the people who should be handling exceptions instead.
An AI document agent removes the retyping without removing control. It reads the file, extracts the agreed fields, checks them against your rules, and prepares a record for approval. Your team reviews what is uncertain instead of copying what is obvious.
What the agent actually does
The agent watches the place where documents already arrive: a shared inbox, a folder, an upload form, or a portal export. Each new file is classified by type, because a purchase order and a credit note need different fields and different checks.
It then extracts the fields your ERP needs, validates them, and either writes the record or sends it to a review queue. Every extracted value keeps a link to the page it came from, so a reviewer can confirm it in seconds.
- Classify the document: purchase order, invoice, delivery note, form, or other
- Extract header fields and line items into a structured record
- Check totals, dates, required fields, and known customer or supplier codes
- Write clean records to the ERP and route exceptions to a person
- Keep the source page reference and the approval history
Validation is where the value sits
Reading a PDF is the easy part. The useful part is knowing when the result is wrong. A line total that does not match quantity times price, a supplier code that does not exist, or a delivery date in the past should never be written silently.
We build the checks from your own rules and past corrections. Anything that fails a check, or any field the model is unsure about, goes to review with the reason attached.
- Arithmetic checks on totals, tax, and line items
- Lookups against customer, supplier, product, and price lists
- Duplicate detection so the same document is never entered twice
- Confidence thresholds that send uncertain fields to a person
What stays manual
The agent handles the repeated reading and typing. Your team keeps the decisions: approving unusual orders, resolving pricing disputes, and handling documents that do not fit any known pattern.
This split matters for trust. People accept an agent faster when they can see exactly what it did and when it stopped to ask.
Proof from our own document work
BookSmart processes invoices and bank statements with separate extraction prompts for each document type, plus a dedicated parser for structured accounting files. LetterMate runs 20 guided letter types and has produced more than 12,000 letters at 70% lower cost than the manual process it replaced.
Planroom, our construction document system, was evaluated on 15 real bid packages, including a 62-document package with a 1,543-page specification. The lesson from that work is the one we apply everywhere: show the source, flag the gaps, and let a person approve.
How to start
Pick one document type that arrives often and gets typed by hand. Send us a few redacted examples and the fields your ERP needs. The free Agent Audit comes back within 24 hours with the first agent, the price, and what should wait.
A Starter Agent covers one document type and up to two of your existing tools for $1,000, live in one week. If it does not work as agreed in writing, we fix it at no charge or refund the $1,000. Managed AI Operations, from $1,000 a month, keeps it accurate and adds the next document type.
FAQ
Can AI extract data from scanned PDFs, not just digital ones?
Yes. Scanned files go through OCR before extraction. Scan quality affects accuracy, so low-confidence fields are routed to review instead of being written automatically.
Which ERPs can the agent write into?
Any ERP with an API or a reliable import path. Where no API exists, the agent can produce a validated import file for your team to load.
How accurate is AI data extraction?
Accuracy depends on document quality and consistency. We measure it on your own samples before launch and keep a review queue for anything uncertain, so errors are caught before they reach the ERP.
Do we have to change how suppliers send documents?
No. The agent works from the inbox, folder, or portal your documents already arrive in.
