In many medium-sized companies, matching purchase orders, delivery notes, and invoices is a tedious, uphill battle. Manual processes, confusing Excel sheets, and a lack of transparency not only cost valuable time and energy but also carry significant financial risks. Incorrect deliveries, over-ordered goods, or duplicate payments are the expensive consequences. But there’s a solution that revolutionizes this process and gives you back full control.

This article will show you how to use intelligent, automated three-way matching to reduce manual effort by up to 99%, save costs, and gain an unprecedented overview of your entire purchasing process.

An End to Chaos: Why Manual Matching Has Its Limits

The classic procurement process in many SMEs is fragmented. Orders are placed by email or phone, delivery notes land unsorted in the goods receiving area, and invoices arrive by mail in the accounting department. The task of manually reconciling these three documents—purchase order, delivery note, and invoice—is not only time-consuming but also extremely prone to errors.

Imagine this scenario: an employee orders spare parts, but the delivery arrives incomplete. Without a clean match against the original purchase order, this might only be noticed when the technician is on-site with the customer and the crucial part is missing. The result: angry customers, extra trips, and unnecessary costs. Or, too much is delivered, and the excess goods end up unnoticed in the warehouse, tying up capital. With finway, such problems become a thing of the past.

Three-Way Matching: Your Shield Against Errors and Fraud

Three-way matching is a central control mechanism in financial accounting. It ensures that a company only pays for what it ordered and actually received. This involves comparing three documents:

  1. Purchase Order: What was ordered and at what price?
  2. Delivery Note/Goods Receipt: What was actually delivered?
  3. Invoice: What is being billed?

If all three documents match, the invoice is approved for payment. This process effectively prevents overpayments, protects against fraud attempts, and ensures the accuracy of your bookkeeping.

Why Matching at the Line-Item Level is Crucial

A critical factor for the effectiveness of three-way matching is the level of detail. A reconciliation that only compares the total amounts of an invoice and a purchase order is insufficient. True precision and control are only achieved through matching at the line-item level.

This means every single item—every screw, every license, every service—is checked for quantity, item description, and price. This is the only way you can reliably identify discrepancies such as partial deliveries, incorrect items, or price errors. A system that doesn’t do this offers only a false sense of security.

Just think about how often you have partial deliveries or partial payments, or how often you receive deliveries and invoices that relate to different orders and deliveries.

finway: Your Path to 99% Automation in Purchase-to-Pay

This is where finway’s strength comes into play. Our purchase-to-pay software is designed to digitize and automate the entire purchasing process, from the purchase request to the final payment. At its core is our AI-powered three-way match, which reduces manual effort by up to 99%.

Here’s how it works:

  1. Digital ordering: Employees can create purchase requests easily and intuitively in finway. Once approved, a legally compliant purchase order is automatically generated. Alternatively, orders created in the inventory management system can be exported and uploaded to finway.
  2. Mobile goods receipt: When the delivery arrives, your employees simply upload the delivery note to finway. AI-supported OCR recognition captures all relevant data from the delivery note. As with orders, it is also possible to export delivery notes from your existing merchandise management system and transfer them to finway.
  3. Automatic matching: In the background, finway now automatically reconciles the digital delivery note with the original order at item level. If you receive partial deliveries for an order, you can easily upload multiple delivery notes and link them to one orders
  4. Intelligent invoice verification: When the invoice arrives, it is also digitally captured and compared by the AI with the data from the order and delivery note.

If there’s a perfect match, the invoice is automatically approved for payment and processed without manual intervention. In case of discrepancies—such as in quantity, price, or item—the system immediately alerts the responsible employees. This allows issues to be resolved before an incorrect payment is made.

Why Companies Switch from Inventory Management & ERP to finway

Many medium-sized businesses use inventory management (WaWi) or ERP systems. However, these are often complex, rigid, and oversized for the pure purchasing process. Creating a purchase order can be complicated and is often reserved for trained personnel. In practice, this leads to employees bypassing these systems and ordering informally—and the chaos begins.

  • Transparency: You have a complete overview of all orders, budgets, and expenses in real-time.
