Zero-Entry A/P: When Agents Read Invoices Better Than Humans
Achieving true touchless Accounts Payable. How agents extract data, code GLs, and route for approval without human fingers.
For decades, Accounts Payable has been a data entry factory. Invoices arrive by email, mail, or portal. Humans open them, read them, and key the data into the ERP. OCR (Optical Character Recognition) promised to automate this, but it often requires templates and manual verification. It read the characters, but it didn't understand the context.
2026 marks the end of data entry. Generative AI agents don't just "see" pixels; they understand documents. They know that "Total Due" is the implementation of a payment obligation, not just text on a page. ChatFin's agents are delivering the promise of Zero Entry A/P.
Beyond OCR: True Understanding
Traditional OCR is rigid. If a vendor moves their logo or changes the font, the template breaks. Generative AI is flexible. It reads an invoice like a human does. It identifies the vendor, the date, the line items, and the total, regardless of the layout.
Whether it's a crumpled receipt photo, a PDF attachment, or the body of an email, the agent extracts the relevant data with near perfect accuracy. No templates required.
Autonomous GL Coding
Extracting data is step one. Knowing where to book it is step two. Humans rely on memory or cheat sheets ("Office supplies go to 6020"). Agents rely on history and context.
The agent analyzes the line item description ("MacBook Pro 16 inch") and the vendor ("Apple Store"). It looks at historical transactions and determines that this should be capitalized as IT Hardware, not expensed as Office Supplies. It applies the correct GL code, department, and project code automatically.
The 3-Way Match Executed
The control freak of accounting is the 3 Way Match: Invoice = PO = Receipt. Humans spend hours hunting down missing receipts or investigating price variances. Agents do this instantly.
When an invoice arrives, the agent checks the PO and the Goods Receipt Note in the ERP. If they match within tolerance, the invoice is posted and scheduled for payment. If there's a discrepancy, the agent drafts an email to the vendor asking for clarification—"Hi, you billed us for 10 units but we only received 8. Please advise."
Intelligent Routing
Not every invoice needs CFO approval. The agent understands the delegation of authority matrix. It routes a $50 software subscription to the IT manager and a $50,000 consulting fee to the VP of Finance.
Because the agent operates 24/7, approvals don't sit in inboxes. The agent can ping approvers on Slack or Teams ("New invoice from AWS for $3,200. Within budget. Approve?") making the process frictionless.
Conclusion
Zero Entry A/P isn't just about saving labor costs; it's about speed and accuracy. It transforms A/P from a back office processing function into a strategic data asset.
