Streamlining Accounts Payable with Copilot Payables Agent & Azure Document Intelligence

Accounts payable has never been the most glamorous part of finance operations, but it's one of the most critical. For small and mid-sized businesses (SMBs), proper management of invoices, vendor relationships, and payments can be the difference between smooth operations and cash flow chaos.

Industry

Traditionally, accounts payable work has been time-consuming, manual, and prone to errors. But with the rise of accounts payable automation and AI-powered invoice processing, finance teams now have the chance to free themselves from repetitive data entry and focus on strategic, high-value work.

In this blog, we’ll explore how the Microsoft Copilot Payables Agent, powered by Azure Document Intelligence, is transforming accounts payable for SMBs. We’ll break down what accounts payable automation really means, why it matters, and how you can start using AI to handle invoice processing with greater accuracy and efficiency.

What is accounts payable automation?

At its core, accounts payable automation refers to using software and AI tools to streamline the entire AP cycle, from receiving an invoice to approving and paying it. Instead of manually entering data, chasing down approvals, or cross-checking vendor information, automation systems do the heavy lifting.

Some of the most common functions include:

Automated invoice capture: Uses OCR (optical character recognition) and AI to read and extract data from invoices
Invoice validation: Automatically checks vendor details, purchase orders, and payment terms.
Approval workflows: Routes invoices to the right people without endless email chains.
Payment processing: Ensures vendors get paid on time with fewer manual touchpoints.

The global adoption of AP automation is growing quickly. According to industry reports, nearly 80% of businesses are exploring or already investing in automation tools to improve financial operations.

Why automate accounts payable? The compelling business case

Moving from manual to automated accounts payable delivers measurable benefits across multiple areas:

01 Cost and efficiency impact

02 Error reduction and accuracy

03 Compliance and audit readiness

04 Strategic focus

Manual processing can cost upwards of $12–15 per invoice, while automation cuts that cost dramatically. Invoices get processed in minutes instead of days, helping vendors get paid faster and strengthening relationships. For SMBs, these improvements can mean fewer late fees, improved cash flow, and more time for finance teams to focus on strategy.

Typos, misplaced decimals, duplicate entries, and incorrect vendor assignments are costly mistakes that plague manual processes. AI-driven validation typically reduces error rates by up to 90%, preventing duplicate payments and mistyped amounts that can have huge financial consequences.

Automation creates clear digital trails with complete documentation, making compliance and reporting much easier. This eliminates the common pain points of lost invoices, missing approvals, and lack of visibility that cause issues during financial audits.

Perhaps most importantly, automation frees finance teams from transaction processing to become strategic partners, delivering insights that directly influence growth, profitability, and resilience.

Common challenges in manual AP processes

Before diving into solutions, let's acknowledge the pain points that drive businesses toward automation:

Data entry errors: Even the most careful finance professionals make mistakes when entering data.
Delays in approvals: Paper-based or email-based workflows create bottlenecks that slow vendor payments.
Lost or duplicate invoices: These issues are harder to spot manually, especially as invoice volumes scale.
Compliance risks: Lack of visibility and audit trails can cause serious issues during financial reviews.

These are exactly the challenges that the Microsoft Copilot Payables Agent and Azure Document Intelligence were designed to solve.

Microsoft Copilot Payables Agent overview

What is the Copilot Payables Agent?

The Copilot Payables Agent is Microsoft's native solution for automating invoice processing within Business Central. Think of it as a digital finance assistant that reduces manual effort, improves accuracy, and maintains seamless integration with your existing Microsoft ecosystem.

Because it's built directly into Business Central, it eliminates the need for costly third-party extensions, giving SMBs greater control, scalability, and streamlined workflows without additional middleware.

Key functions and workflow

Here's what the Copilot Payables Agent handles automatically:

Invoice ingestion: Receives vendor invoices from your designated email inbox in multiple PDF formats.
AI-powered data extraction: Uses advanced document intelligence to capture key details like vendor information, invoice numbers, amounts, dates, and line items.
Vendor matching: Automatically links invoices with existing vendor records in Business Central.
Draft creation: Generates accurate draft purchase invoices ready for review and approval.

The result? Less manual data entry, fewer processing errors, and faster invoice turnaround times that keep vendors happy and cash flow predictable.

Deep dive: Azure Document Intelligence

01 What is Azure Document Intelligence?

02 How does Azure Document Intelligence power AP automation?

Azure AI Document Intelligence (formerly Form Recognizer) is the powerful AI engine that makes intelligent invoice processing possible. This service extracts structured data from unstructured documents, essentially reading documents the way humans do, but at scale and more accurately.

Core capabilities include:

Pre-trained models specifically designed for invoices, receipts, and purchase orders that work out of the box.
Custom model training for specialized document types unique to your business.
Advanced OCR and AI extraction that captures text, tables, key-value pairs, and complex layouts accurately.

When integrated with the Copilot Payables Agent, Azure Document Intelligence becomes the brains behind true AI invoice processing:

OCR scanning: Reads invoices in PDF, image, or scanned formats with high accuracy.
Intelligent extraction: Captures critical fields like vendor names, invoice dates, amounts, tax information, and line item details.
Automated validation: Cross-checks extracted data against existing Business Central vendor records and purchase orders.
Quality assurance: Flags potential issues or discrepancies for human review.

This integration ensures invoices move seamlessly from "received" to "processed" with minimal human intervention while maintaining accuracy and control.

Customer and employee experiences

Prerequisites and setup requirements

Before activating the Payables Agent, you'll need these foundational elements in place:

Microsoft 365 mailbox for invoices: The agent monitors a designated shared mailbox or user mailbox where vendors send invoice PDFs. This centralized inbox becomes the entry point for all automated processing.

Consumption-based billing setup: Since the Payables Agent uses Microsoft Copilot Studio to process requests, your Business Central environment needs billing configured in the Admin Center. This is a pay-as-you-go model, so you're only charged for actual usage.

Think of these as the essential 'plumbing' that enables automation. Once configured, the agent can begin monitoring and processing invoices automatically.

Step-by-step implementation guide

To set up the Payables Agent, follow these key steps in Business Central:

1. Enable the feature:

Navigate to the Copilot & agent capabilities page and activate the Payables Agent under Production-ready previews.

2. Initial activation:

Click the Payables Agent icon in the top navigation bar, select Activate, and launch the configuration wizard.

3. Configure invoice monitoring:

Enable the Monitor incoming information toggle and connect your designated Microsoft 365 mailbox.

5. Activate and test:

Enable the Active switch, confirm your language setting matches supported English locales, and begin processing test invoices.

Smart setup and optimization best practices

Document quality matters:

Request digital PDFs from vendors whenever possible. Clean, text-based invoices produce better results than scanned copies with handwritten notes or poor image quality.

Standardize vendor communication:

Work with vendors to include consistent information like invoice numbers and purchase order references in both the document and email subject lines.

Configure realistic tolerances:

Set practical matching thresholds for 2-way or 3-way matching to avoid overwhelming your exception queue with minor variances.

Implement proper permissions:

Ensure segregation of duties by never allowing the same person to both review and post invoices.

Organize document retention:

Store original PDFs alongside posted invoices using Business Central and SharePoint integration for future audit requirements.

Explore additional fields:

Use the Configure additional fields option to capture extra invoice line details that may be specific to your business needs.
