It reads, matches, routes and watches, so the team can decide. PS **Pranjali Singh**Jan 27, 2023 ยท 4 min read Accounts payable teams are expected to do more than pay bills. Finance leaders want a live view of liabilities, tight control over spending and fewer surprises at month end. Meeting those expectations by hand is hard. Artificial intelligence, applied to the right tasks, makes it realistic. This guide explains what AI is in plain terms, what it does in accounts payable, the three main use cases and the benefits teams see. It was first published in early 2023 and has been updated for the generative AI tools teams use in 2026. Key takeaways - AI lets software learn from examples rather than follow fixed rules for every case - In accounts payable it reads documents, matches data, routes approvals and flags risk - Invoices, quotations and purchase orders are the three main documents to automate - Benefits include faster cycles, fewer errors, more discounts and better visibility - A person still approves payments and resolves exceptions ## What is artificial intelligence, in plain terms? Artificial intelligence is the ability of software to perform tasks that normally need human judgment, such as reading a document, recognizing patterns or suggesting a next step. Phone keyboards that suggest the next word and cars that park themselves are everyday examples. Machine learning is the part of AI that improves with experience. The more invoices a model sees, the better it becomes at reading new ones. Generative AI, built on large language models, adds the ability to understand and write text, so it can explain an exception or draft a query to a supplier. ## What does AI do in accounts payable? AI improves accounts payable in four ways: - **Reading:**it identifies and extracts data from invoices, purchase orders and other documents far faster than people can, using optical character recognition where documents are images and machine learning to understand what each field means. - **Matching:**it compares invoice data with purchase orders, receipts and contract terms, and flags differences beyond your tolerances. - **Routing:**it sends invoices to the right approver based on rules and history, applies spending limits and sends reminders. - **Watching:**it spots duplicates, unusual amounts and changes to supplier payment details that may signal fraud. The result is faster processing with fewer touches, fewer mistakes and more early payment discounts captured. ## What are the main use cases for AI in accounts payable? ### 1. Invoice automation AI extracts header and line item data from supplier invoices, checks it and compares it with the purchase order data already in your enterprise resource planning system. Clean invoices move straight to approval. This is where most teams start, because it removes the most manual work. See [touchless invoice processing](https://aavenir.com/ai-enabled-touchless-invoice-processing/). ### 2. Quotation processing Supplier quotes arrive in many formats. AI turns them into standard, structured electronic quotes, so buyers can compare them quickly and respond faster. ### 3. Purchase order processing Where orders still arrive on paper, as scans or by fax, AI extracts the order data and checks it against catalogs and master data, reducing errors before they reach the invoice stage. ## What benefits do teams see? | Benefit | How AI delivers it | | Lower cost | Less manual keying, printing and physical storage | | --- | --- | | Faster approvals | Invoices reach the right approver with the context they need | | Better supplier relationships | On time payment and fewer status inquiries | | More engaged staff | Less repetitive work, more problem solving | | Visibility | Every document tracked, one source of truth for unpaid liabilities | | Audit readiness | Every step and decision logged in real time | Finance leaders can see any document in motion through the process, which makes audits simpler and month end less stressful. ## What has generative AI added? Earlier AI in accounts payable mostly read and matched. Generative AI can also explain and draft. It can summarize why an invoice failed matching, draft the query to the supplier, suggest coding based on similar past invoices, or answer a question such as which suppliers billed above contract rates last quarter. In Aavenir, Aavenir AI does this inside [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/), including checking invoice lines against the contract that governs them. Each suggestion goes to a person, who accepts or changes it, and the decision is logged.

If supplier records are duplicated, purchase orders are raised after the invoice or receipts are recorded late, the model will flag exceptions that are really process problems. Fixing those habits often does more for the touchless rate than any model upgrade. AI also struggles with the genuinely unusual: a one off invoice for a disputed service, a supplier that bills in a format nobody has seen or a payment that depends on a side agreement. Those should go to a person, with the AI explaining why it stopped. And no AI should release a payment on its own. Approval limits, segregation of duties and a human decision on every payment run remain the core controls. ## How should you introduce AI into accounts payable? - **Fix the basics:**clean supplier records and consistent purchase orders make AI far more accurate. - **Start with invoices:**automate extraction and matching for your highest volume suppliers. - **Set tolerances carefully:**decide what differences need a person. - **Keep people on payments:**AI recommends, people approve. - **Measure:**track cycle time, touchless rate and exceptions by cause against your starting point. Then extend to quotations, purchase orders and contract checks as confidence grows. ## The bottom line Artificial intelligence takes the reading, matching and watching out of accounts payable, so people can focus on exceptions, suppliers and cash. Start with invoices, keep a person approving payments and measure the results in your own numbers. ### In this article - What is artificial intelligence, in plain terms? - What does AI do in accounts payable? - What are the main use cases for AI in accounts payable? - What benefits do teams see? - What has generative AI added? - What are the limits of AI in accounts payable? - How should you introduce AI into accounts payable? **See Avy in Invoiceflow**Extraction, matching and contract checks on your invoices.

AI reads invoices and other documents, extracts their data, matches it against purchase orders, receipts and contracts, routes approvals and flags duplicates or unusual payments. Generative AI can also explain exceptions and draft supplier queries. People approve payments. See [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/). ### ### What is the difference between optical character recognition and AI in accounts payable? Optical character recognition turns an image into text. AI, through machine learning, works out what that text means, such as which number is the total or the order reference, and can match, route and flag it. Most systems use both. Learn about [invoice data extraction](https://aavenir.com/glossary/invoice-data-extraction/). ### ### Will AI replace accounts payable staff? No. AI removes repetitive keying and checking, but people still resolve exceptions, manage supplier relationships, approve payments and own controls. Teams usually move to more analytical work as volumes grow. Read [the accounts payable workflow guide](https://aavenir.com/accounts-payable-workflow-101/). Have a question we have not answered?
