In accounts payable (AP) automation, 2-way, 3-way, and 4-way matching are critical processes for ensuring invoice accuracy before authorizing them for payment. These matching methods serve to verify that businesses only pay for items and services that were properly ordered, received, and, where relevant, inspected. The steps involved in each matching process, the validation rules they follow, the difficulties they encounter, and how iKapture handles partial invoice posting are all explained in detail below.

Understanding 2-Way Matching in iKapture

2-Way Matching is the simplest form of invoice verification in AP automation. In iKapture’s implementation, this process involves comparing two key documents: the Purchase Order (PO) and the Supplier Invoice. The system meticulously examines the item descriptions, quantities, and prices on both documents to ensure they align perfectly.

When iKapture detects a match between the PO and invoice details, it automatically creates the invoice and routes it through the approval process for payment. This streamlined approach helps businesses quickly process straightforward transactions, reducing the time and effort required for invoice processing.

Price Validation

iKapture ensures that the invoice price exactly matches the price specified in the Purchase Order, preventing any unauthorized price changes.

 Quantity Check

The system verifies that the invoiced quantity does not exceed the ordered quantity, safeguarding against over- billing.

 Total Amount Verification

iKapture compares the invoice total against the PO total, ensuring that the overall transaction value remains consistent.

Challenges and Limitations of 2-Way Matching

While 2-Way Matching offers efficiency benefits, it’s important to acknowledge its limitations. The primary challenge lies in its limited scope, as it does not incorporate verification of goods receipt.

This omission can potentially lead to overpayments if invoices are processed before goods are actually received.

Additionally, 2-Way Matching may not catch discrepancies that arise during the fulfillment process, such as partial deliveries or quality issues. These limitations underscore the importance of implementing more comprehensive matching processes for complex or high-value transactions.

 3-Way Matching: Enhanced Verification in iKapture

3-Way Matching in iKapture represents a significant step up in invoice verification complexity and accuracy. This process incorporates an additional document into the verification workflow: the Receiving Report, also known as the Goods Receipt. By comparing the Purchase Order, Receiving Report, and Supplier Invoice, iKapture provides a more comprehensive check before approving an invoice for payment.

The inclusion of the Receiving Report allows iKapture to verify not only that the ordered items match the invoice but also that the goods have actually been received as specified. This additional layer of verification helps prevent payments for undelivered or partially delivered goods, significantly reducing the risk of overpayment or fraud.

PO Verification

iKapture compares the invoice details against the original Purchase Order, checking for matching item descriptions, quantities, and prices.

Receipt Confirmation

The system cross-references the Receiving Report to ensure that the goods or services have been delivered as ordered.

Invoice Validation

Finally, iKapture verifies that the invoice details align with both the PO and the Receiving Report before approving for payment.

 Validation Rules and Challenges in 3-Way Matching

iKapture’s 3-Way Matching process adheres to strict validation rules to ensure accuracy. The system verifies that the invoice price matches the PO price, the received quantity aligns with both the ordered and invoiced quantity, and the invoice total corresponds with both the PO and receiving report. These stringent checks help maintain financial integrity and prevent discrepancies.

However, the increased complexity of 3-Way Matching presents its own challenges. Coordinating and reconciling three separate documents can be time-consuming and may introduce delays in the payment process. Additionally, discrepancies between documents, such as partial deliveries or price changes, require careful handling and often necessitate human intervention to resolve.

 4-Way Matching: Maximum Verification with iKapture

4-Way Matching represents the most comprehensive invoice verification process offered by iKapture. This method introduces a fourth document into the matching workflow: the Inspection or Quality Report. By incorporating this additional layer of verification, businesses can ensure not only that goods have been ordered and received but also that they meet the required quality standards before payment is authorized.

In iKapture’s 4-Way Matching process, the system meticulously compares the Purchase Order, Receiving Report, Inspection Report, and Supplier Invoice. This thorough approach is particularly valuable for industries where product quality is critical, such as manufacturing, pharmaceuticals, or food production.

Document Comparison

iKapture cross-references four distinct documents: PO, Receiving Report, Inspection Report, and Invoice, ensuring complete alignment across all stages of the procurement process.

Quality Assurance

The inclusion of the Inspection Report allows for verification that received goods meet specified quality standards before payment is authorized.

 Comprehensive Validation

iKapture performs thorough checks on price, quantity, quality, and total amount across all four documents, providing the highest level of accuracy and control.

Challenges and Considerations in 4-Way Matching

While 4-Way Matching offers the most robust verification process, it also presents significant challenges. The complexity of managing and reconciling four separate documents can lead to increased processing times and potential bottlenecks in the AP workflow. The additional quality checks, while valuable, may introduce delays in the payment process, particularly if inspection results are not promptly recorded or if quality issues are identified.


Furthermore, 4-Way Matching requires seamless integration between various departments, including purchasing, receiving, quality control, and accounts payable. iKapture addresses these challenges by providing a centralized platform that facilitates communication and document sharing across departments, streamlining the complex 4-Way Matching process.

 Partial Invoice Posting: iKapture’s Flexible Approach

iKapture’s AP automation system is designed to handle the complexities of partial deliveries and invoices, a common occurrence in many business transactions. The system’s partial invoice posting feature allows for the processing of invoices for partially fulfilled orders, ensuring timely payments while maintaining accurate financial records.

When a partial delivery occurs, iKapture records this information in the receiving report. The system then matches the partial invoice with the corresponding portion of the Purchase Order and the recorded partial delivery. This allows for the processing and payment of the invoice for the delivered portion while updating the remaining balance on the PO.

Partial Delivery Recording

iKapture accurately logs the details of partial deliveries in the receiving report, creating a clear record of what has been received.

Proportional Matching

The system matches the partial invoice against the corresponding PO portion and the recorded partial delivery, ensuring accuracy in payment.

Balance Update

After processing the partial payment, iKapture automatically updates the remaining PO balance, maintaining an accurate record for future deliveries and invoices.

 Validation Rules for Partial Invoice Posting

iKapture employs stringent validation rules to ensure the accuracy of partial invoice posting. The system performs partial quantity validation, verifying that the quantity on the partial invoice matches the delivered quantity. It also conducts proportional amount validation, ensuring that the invoice amount corresponds accurately to the delivered portion of the order.

A critical aspect of iKapture’s partial invoice posting is the remaining balance validation. The system meticulously tracks the remaining balance on the Purchase Order, preventing overpayment and ensuring accurate matching with subsequent invoices. This comprehensive approach allows businesses to confidently manage complex purchasing arrangements while maintaining financial control.
