What is Invoice Processing?

Invoice processing is the comprehensive management of incoming invoices from vendors or suppliers, from their initial receipt to final payment.

The process involves verifying invoice accuracy, matching them to purchase orders, approving payments, and recording transactions in the general ledger. This process is essential for maintaining accurate financial records and ensuring timely payments to suppliers.

Examples of Invoice Processing

When a company makes a purchase, the vendor issues an invoice for the amount owed. The finance team then records this in accounts payable and pays the vendor. This process, from receipt to payment, is termed invoice processing.

Processing invoices on time is a critical factor in maintaining a smooth flow of raw materials and services for your business operations.

Types of Invoice Processing Methods

Here’s the two types of invoice processing methods:

1. Automated Invoice Processing

Automated invoice processing streamlines the entire workflow through the use of advanced technologies:

STEP 1: Receiving the invoice

Receiving invoices from vendors or suppliers through various channels like Physical mail, Email, Electronic data interchange (EDI) and Portal or online platform.

STEP 2: Data extraction

Using Intelligent OCR and machine learning, the software captures data from both paper-based invoices and electronic invoices (e-invoice).

STEP 3: Automatic data entry

The extracted invoice data is automatically entered into the invoice management system or software.

STEP 4: Validation

The invoice software checks the data against predefined rules and flags any discrepancies for manual review.

STEP 5: Automated approval workflow

Integrated with ERP systems, the invoice software automates approval notifications and task assignments.

STEP 6: Payment processing

Once the invoice is approved for payment processing, the invoice software automatically processes the payments to vendors.

This structured, step-by-step approach highlights the efficiency gains of automation over manual methods.

2. Manual Invoice Processing

The traditional method of invoice handling involves several manual steps:

STEP 1: Receiving the invoice

Invoices are received, often in paper form or via email.

STEP 2: Manual data entry

Information is manually entered into the accounting system.

STEP 3: Verification

Invoices are checked against purchase orders and receipts for accuracy.

STEP 4: Record-keeping

A copy of the invoice is filed for future reference.

STEP 5: Approval process

Invoices must be routed for approval before payment is initiated.

This manual process is prone to errors such as data entry mistakes, missed approvals, and delays. Handling a large volume of invoices requires significant time and attention, which can lead to delayed payments and inefficiencies.

The Invoice Processing Workflow: A Step-by-Step Guide

STEP 1: Invoice Receipt

Vendors send invoices through various channels such as email, physical mail, fax, or accounts payable software.

These invoices include details like

  • Due date
  • Total amount
  • Product codes
  • Quantities
  • Contact information for both parties.

2. Data Entry

  • Once the invoice is received, its details are entered into the accounting system either manually or automatically using OCR (Optical Character Recognition) technology, which digitizes paper invoices.
  • Ensuring accurate data entry is critical for the rest of the process.

3. Verification and Approval

  • Invoices are verified by cross-referencing them with documents such as purchase orders and delivery receipts (a process known as 3-way matching).
  • After verification, key stakeholders review the invoice and supporting documents for approval before payment is processed.

4. Coding and Classification

  • Each invoice is assigned a General Ledger (G/L) code based on the type of expense it represents.
  • These codes ensure proper classification in the accounting system, making financial tracking and reporting more efficient.

5. Invoice Payment Processing

  • Once approved, the invoice is processed for payment.
  • Invoice payment methods include wire transfers, ACH (Automated Clearing House) payments, or via electronic payment system, depending on company policies and the terms agreed upon with the vendor.

6. Record Keeping

  • After the payment is completed, the transaction is recorded in the general ledger.
  • This step is crucial for tracking expenditures, maintaining financial transparency, and ensuring compliance with regulatory requirements.
