Three-way matching (3WM) has long been a cornerstone of Accounts Payable (AP) processes, ensuring that every invoice, purchase order (PO), and goods receipt note (GRN) align before payments are approved. At its core, it’s a simple control mechanism designed to avoid overpayments, fraud, and financial discrepancies.

But here’s the catch: while 3WM works as a necessary safeguard, it’s also one of the most time-consuming, error-prone processes for AP teams. The manual nature of this reconciliation creates bottlenecks, frustrates teams, and introduces significant delays.

What if you could eliminate the friction of manual matching while maintaining 100% control over your accounts payable process?

‍

What Is 3-Way Matching (and Why It Breaks at Scale)

3-way matching (3WM) refers to the practice of cross-referencing three key documents:

1. Purchase Orders (PO): What was requested
2. Goods Receipt Notes (GRN): What was delivered
3. Invoices: What was billed

While the theory is simple: match them, confirm that the quantities and costs align, and then pay, it’s far from straightforward when scaled.

‍

Common friction points in 3WM include:

• Timing mismatches: GRNs arriving after invoices, meaning your team must manually adjust for delivery delays or partial receipts.
• Partial deliveries: Where goods are delivered in multiple shipments, but the invoice arrives for the full order, complicating the matching process.
• Invoice errors: Simple mistakes like incorrect tax rates or misdescribed products, often lead to time-consuming follow-ups.

When these issues occur, manual reconciliation becomes a slow, repetitive process that takes up hours of your team’s time delaying approvals, causing frustration with vendors, and resulting in potential overpayments.

‍

Why Most AP Teams Still Struggle with It

Even with modern ERP systems, 3WM remains a pain point for many AP teams. Why?

• Legacy ERPs aren’t built for the nuances of modern AP workflows. Many systems offer rigid matching logic, which doesn’t account for complexities such as multi-line invoices, partial deliveries, or varying formats.
• Matching rules are hardcoded: This makes it difficult to adapt the system to specific vendor requirements or exceptions that arise.
• Exception handling requires tribal knowledge: AP teams are often left to manually resolve exceptions based on experience, which can lead to delays and errors, especially when team members rotate or leave.

These workarounds (Excel, manual reconciliations, and multiple back-and-forth emails) may help teams manage the load, but they also consume valuable time and increase the risk of error.

The bottom line? Manual matching breaks when complexity increases. Finance teams aren’t designed to chase data across multiple systems and formats. They’re built to analyze and optimize.

Introducing Supervity's Accounts Payable AI Employee: A Smarter Way to Match

This is where Supervity’s Accounts Payable AI Employee steps in. With the help of our AI-powered employee, 3-way matching can transform from a manual, error-prone task to a seamless, real-time process that runs autonomously.

‍

How does it work?

• AI-powered document parsing: Using large language models (LLMs), AI can read and extract data from a variety of documents; from PDFs and scans to emails and ERP exports. No more waiting for documents to be uploaded or matched manually.
• Smart matching: AI can learn your vendors' formats and rules, automatically handling the most complex matches, even when discrepancies arise. This means more accurate matching and fewer mistakes.
• Intelligent exception handling: AI detects mismatches (like incorrect quantities or prices) and flags them in real-time, providing reason codes and solutions for human intervention only when necessary.
• Real-time reconciliation: The AI can reconcile documents on the fly, ensuring all entries align before payments are processed. This cuts down on cycle time and ensures greater compliance.

By introducing AI-powered 3-way matching, AP teams can work smarter, not harder, allowing them to automate low-value tasks and focus on what truly matters: strategic decision-making and building vendor relationships.

How Supervity’s AI Employee Enhances 3-Way Matching

Let’s break this down in real-world terms:

Imagine your team receives an invoice for 100 units of a product, but the GRN reflects a partial shipment; only 60 units were received. Normally, this would trigger a frustrating back-and-forth with vendors and approval delays.

‍

With Supervity’s AI Accounts Payable Employee, this is handled in seconds:

• Documents are automatically ingested (PO, GRN, and invoice).
• The AI reads and compares each line item.
• It flags the discrepancy with a clear reason code (i.e., “partial delivery”).
• The invoice awaits approval with a suggestion for action, no back-and-forth emails required.

The result is a much faster, error-free process that lets your team focus on value-add activities, while Supervity handles the mundane.

Outcomes That Matter to Finance Teams

Switching to an AI-powered 3-way matching solution offers benefits that matter, not just for your AP team, but for the entire organization.

1. Faster invoice cycle time: Reduces invoice processing from 10–14 days to under 2 days.
2. Fewer manual approvals needed: By automating routine checks, AI eliminates the need for constant follow-ups and escalations.
3. Lower exception rates: Smart matching and real-time reconciliation reduce mismatches and discrepancies.
4. Increased compliance: Every action is logged, ensuring audits are faster, easier, and fully transparent.
5. Higher team morale: By eliminating repetitive work, AI allows your team to focus on higher-value tasks, reducing fatigue and increasing job satisfaction.

These are not just improvements, they’re transformations.
