AI Accounts Payable for Accounting Firms: What Can Actually Be Automated?

What AI Can Actually Do in Accounts Payable

Accounts payable is one of the accounting workflows where AI can remove a significant amount of repetitive work. Instead of manually entering invoice information, checking documents and chasing routine approvals, accounting firms can use AI-powered tools to automate parts of the process while keeping people responsible for review and exceptions.

The key is understanding what should actually be automated. AI is generally better suited to repetitive, rules-based tasks than decisions requiring professional judgement.

Invoice Data Extraction

One of the most practical applications is extracting information from supplier invoices. AI can identify details such as the supplier, invoice number, date, amounts, tax information and payment details and transfer them into an accounting system.

This can reduce manual data entry and make invoice processing faster, particularly for firms handling large volumes of documents.

Invoice Matching and Coding

AI can also help match invoices against purchase orders, previous transactions or other available records. It may also suggest account codes based on previous transactions and the information contained in the invoice.

The accountant or bookkeeper can then review unusual or uncertain items rather than manually checking every invoice.

Identifying Exceptions

Exception management is often where AI becomes particularly useful. Instead of treating every invoice in exactly the same way, an AI-enabled workflow can flag potential duplicates, unusual amounts, missing information or transactions that do not follow the expected pattern.

This allows the accounting team to concentrate on the invoices that actually require attention.

Automating Routine Approvals and Communication

Some accounts payable workflows can also automate routine notifications and approval requests. For example, a system could send an invoice to the appropriate person for approval, remind them when an invoice is outstanding, and update the accounting workflow once approval is received.

AI can also help draft routine supplier communications, reducing the amount of repetitive email work involved in the process.

What Should Still Be Reviewed by a Human?

Not every accounts payable decision should be handed to AI. Unusual supplier payments, suspicious invoices, significant financial transactions and exceptions involving tax or compliance may require human investigation.

A useful approach is to automate the predictable transactions while directing unusual or high-risk cases to an accountant for review.

A Practical AI Accounts Payable Workflow

A simple workflow could look like this:

Receive the supplier invoice.
AI extracts the relevant information.
The system checks the invoice for duplicates and obvious inconsistencies.
AI suggests the appropriate coding or matching information.
Routine invoices move through the normal approval process.
Exceptions are flagged for human review.
The approved transaction is posted to the accounting system.
The workflow records what happened for future review.

This creates a balance between automation and professional oversight.

The Opportunity for Accounting Firms

For accounting firms, the biggest opportunity may not be completely removing people from accounts payable. It is reducing the amount of time accountants spend processing routine invoices so they can focus on exceptions, controls, client advice and higher-value work.

As AI becomes more capable, firms can build repeatable accounts payable workflows around the parts of the process that are predictable while keeping human judgement at the points where it matters most.
