How to improve vendor invoice management

Managing vendor invoices efficiently helps your business maintain smooth cash flow and avoid payment delays. Manual tasks, human error, and discrepancies can disrupt your operations, and automation is key to avoiding these problems.

What is vendor invoice management?

Vendor invoice management is the process of handling invoices received from suppliers, ensuring they are verified, approved, and paid on time. It includes managing invoice data, matching invoices with purchase orders, routing them through an approval process, and processing payments.

A well-organized invoice management system helps your business maintain vendor relationships while avoiding late fees and duplicate payments.

Understanding the vendor invoice management process

The vendor invoice management process can be broken down into several steps. Understanding each stage will help you automate the workflow:

1. Invoice receipt: The process begins when your company receives an invoice. Traditionally, this might come in paper invoices, but e-invoicing has become more common. Digital invoices can be automatically entered into your system.
2. Invoice validation: This includes verifying the invoice number, payment terms, and ensuring the details match the purchase order (PO)
3. Approval workflow: A structured approval workflow ensures that the right person authorizes the payment, reducing the risk of errors or fraud
4. Invoice matching: Match the invoice to the corresponding PO to confirm the accuracy of the amounts and details before approval
5. Payment processing: Make the payment. Ensuring timely payments helps maintain positive vendor relationships and may even qualify your company for early payment discounts.

What does a vendor's invoice typically list?

Every vendor invoice you process will have these five parts. Each component can help improve the functionality of your vendor invoice management and payment process.

1. Invoice number

Every invoice issued will include a unique invoice number or purchase order number to help maintain tax and accounting records. Ideally, if you’re consistently using the same providers, they should implement a sequential numbering system to keep everyone organized, meaning increasing the number by one each time they issue a new invoice.

2. Date

This may seem like an obvious line item, but there are likely to be multiple dates on a vendor invoice. In this case, the date refers to the official transaction date and is usually the same date the vendor bills the customer. Vendor invoices will also include a payment due date, which is typically 30 days from the invoice creation, but it may vary depending on the transaction.

3. Contact information

While processing vendor invoices, it’s important to know who, what, and where you need to send payment. Both parties will need to be able to contact one another to make sure there aren’t any issues. Generally, both the buyer and seller information will be listed and include:

• Business or client name
• Business or client address
• Business or client phone number
• Personal or work email address

4. Description of products or services

When a vendor submits an invoice, they include a line item for every product or service in the order. The order lines include the price per unit and the total number of units ordered. At the bottom of the vendor invoice, there is a subtotal for the goods or services, followed by any taxes or additional fees.

5. Payment terms

Before the vendor billing stage, a company usually provides a quote or estimate for its goods or services, which allows the client to compare prices with the competition. As the buyer, it’s important to negotiate with vendors before making a commitment to a particular vendor or their payment terms.

Vendors may offer a line of credit to give their clients the option to pay for goods or services over time, rather than in a lump sum, typically with a monthly or quarterly bill. But either way, you’ll likely run into these common invoice terms:

• Payment in advance (PIA): When a vendor requires payment before providing goods or services. In some cases, you might be asked to pay half upfront and half upon delivery.
• Cash in advance (CIA): Like PIA, CIA is when a vendor expects a full payment in cash upfront before delivering goods or services
• Upon receipt: When a customer is expected to pay in full right after receiving a vendor invoice
• Net 7, 10, 30, 60, 90: This refers to when a net payment is due—i.e., 7, 10, 30, 60, or 90 days after the initial invoice date. In some cases, vendors will offer a 2% discount on a Net 30 if they receive a payment within 10 days, also known as 2/10 Net 30.
• End of month (EOM): When the seller expects to be paid in full by the end of the month of the invoice date. For example, if you received a vendor invoice dated 11/11, you’d be expected to pay in full by 11/30.

Common challenges in vendor invoice management

Despite its importance, vendor invoice management comes with several challenges that businesses face, especially without the right tools or processes in place. Here are some common obstacles:

• Manual tasks: Many companies still rely on manual data entry and paper-based processes, which are prone to errors. Manual processes are not only slow but also create bottlenecks that delay invoice approval and payment.
• Duplicate payments: Without automated checks, businesses may accidentally make duplicate payments. This can be especially problematic if the invoice verification process isn't rigorous.
• Discrepancies: Incorrect invoice details, such as mismatched PO numbers or incorrect pricing, can delay payment processing. If there is a mismatch between the invoice data and the PO, the approval process could stall.
• Bottlenecks: Without an automated approval process, invoices can get stuck at different stages, delaying payment. Manual routing and approval stages can create unnecessary delays.

How automation enhances the vendor invoice management process

Automation is one of the most effective ways to optimize your invoice management process. By integrating technologies such as OCR (Optical Character Recognition) and machine learning, your business can eliminate manual tasks and reduce human error.

Benefits of invoice management automation include:

• Faster processing: Automated systems speed up invoice receipt, validation, and approval, reducing the time spent on manual entry and corrections. The system can instantly verify invoice data and flag duplicate invoices, speeding up the approval process.
• Accurate invoice matching: Automated invoice matching confirms that every invoice corresponds to a legitimate purchase order. This process checks for alignment between the invoice and the purchase order, minimizing potential payment mistakes.
• Audit trail: Automated systems create a reliable audit trail for every invoice processed, improving transparency and accountability. This audit trail helps with tracking and ensures that every transaction is properly documented for compliance and auditing purposes.
• Real-time tracking: Automation provides real-time visibility into your invoice management system, making it easier to track invoice statuses and payments. You can quickly see where an invoice is in the approval process, which helps prevent delays.
