Invoice automation software for processing supplier invoices in accounts payable is essential for streamlining business processes, thereby eliminating manual tasks. With automated invoice processing software, businesses gain efficiency, reduce errors and fraud risks, and achieve real-time visibility to control spending. 

This guide focuses on selecting the best invoice automation software, providing comparisons of five invoice automation solutions to consider during your company’s software evaluation process. 

Top Signs It’s Time to Buy Invoice Automation Software

How do you know it’s time to purchase new tools? Here are a few scenarios:

1. Time-Consuming and Error-Prone Manual Processes

If your business is spending too much time operating a paper-based system requiring manual data entry, it’s time to buy invoice automation software. Your invoice processing cost for accounts payable is too high. Your business may be incurring unnecessary costs due to fraudulent, duplicate, or erroneous invoices that aren’t adequately checked before payment. 

2. Delays in Processing and Recording Supplier Invoices in Accounts Payable

When supplier invoices are not immediately entered into the system, your company doesn’t know its actual cash requirements for accounts payable and can’t properly perform cash flow forecasting. 

The financial statements may be incorrect due to unrecorded payables invoices if your accounting staff does not prepare a time-consuming monthly spreadsheet and journal entry for recording these accounts payable invoices. Your company may miss early payment discount opportunities and incur late payment fees. 

3. Vendor Shipment Cutoffs Due to Late Payments

When your company doesn’t get adequate financing to make timely payments to suppliers, they may cut off goods shipments to your company until payment is received. This interrupts production for manufacturers and the sales stream for retailers with stockouts. 

4. Frequent Hiring or Overtime to Handle the Accounts Payable Workload

A manual system lacks the scalability necessary to handle increased invoice volume as your business expands. As bottlenecks occur and the staff needs to resolve problem invoices and respond to interruptions from supplier late payment inquiries, your AP team may be working overtime and becoming frustrated, or your business may be increasing its headcount. 

5. Lack of Real-Time Spend Visibility

Without real-time supplier invoice recording, your business can’t properly analyze its spending by supplier and category to identify opportunities for cost reduction.  

6. Manual Reconciliation that Delays the Monthly Close 

When your accounting staff needs to manually reconcile payments using spreadsheets, it delays the monthly close. Your accounting staff becomes frustrated because they only have time in their job for completing basic accounting rather than participating in value-adding projects to improve business results. 

7. Year-End Supplier Tax Form Collection and Payment Tracking Projects

If supplier W-9 or W-8 series tax forms aren’t collected before the first payment is made, it requires extra follow-up time at calendar year-end before 1099 forms are due. Your accounting staff may need to prepare spreadsheets to track spending amounts by vendor for the year. 

What is Invoice Automation Software?

Invoice automation software is used by businesses to efficiently process invoices, digitize, and streamline business processes related to receiving and paying invoices from suppliers.

The functions of invoice automation software for accounts payable include:

  • Supplier onboarding and validation, including W-9/W-8 tax form collection
  • Invoice capture via OCR and integrated e-invoicing
  • Automated invoice verification using business rules and 2-/3-way PO matching
  • Approval workflows with access to line-item details and supporting documents
  • Global payments with local currency support and multiple payment methods
  • Regulatory and tax compliance, including sanctions screening and simplified 1099 prep
  • Automated reconciliation of payments to ERP/accounting systems
  • Real-time payment status updates for suppliers
  • AI-driven spend analytics for better visibility and forecasting

Benefits of using invoice automation software include:

  1. Increased accuracy of supplier information
  2. Elimination of manual data entry and paper-based systems
  3. Error and fraud risk detection
  4. Timely invoice processing, to assess current spend and cash requirements and take early payment discounts
  5. Reduced AP staff time for handling supplier invoice payment status inquiries
  6. More cost-effective and automated global payments and currency conversion
  7. Cost reductions from fewer hires, early payment discounts, smarter spend decisions, and strategic focus
  8. Accelerated financial close

Must-Have Features in Modern Invoice Automation Software

Invoice automation software for accounts payable must provide these essential features:

  1. Supplier Portal: Self-service supplier onboarding through a portal enables the collection of W-9 or W-8 forms before the first payment, allows for the selection of a payment method, enhances data accuracy, and provides automated payment status notifications. It enables vendor management for vendor invoice processing. 
  2. Invoice Data Capture: AI-powered invoice data capture, which utilizes AI, optical character recognition (OCR) technology, and machine learning in AP automation, extracts data from files in accepted formats by heading and line item. Automated invoice processing systems with invoice data capture replace inefficient, manual payables systems that are prone to human error and rely on paper invoices and supporting documents, as well as time-consuming manual data entry. 
  3. Automated Workflows: Automation for end-to-end AP processes includes supplier validation, invoice verification rules, 3-way or 2-way invoice matching, invoice approval process routing, global regulatory compliance, global payments, and instant payment reconciliation. It uses automated business rules to detect and flag exceptions. 
  4. Global Accounts Payable: The invoice automation software must provide global functionality, with multiple EFT payment methods to numerous countries in local currencies, currency conversion, and automated global regulatory compliance. Optionally, companies should have access to payables hedging software to manage currency fluctuations between the invoice date and payment date. 
  5. System Integration: The invoice automation software should integrate seamlessly via API or flat file integration with your existing ERP system or accounting software, synchronizing data between systems. Real-time and multi-entity ERP software functionality should enable these capabilities in AP automation software. 
  6. Controls and Security: Enterprise-grade security and secure payment processing capabilities in invoice automation software enable companies to mitigate risks to their business systems and payments. An audit trail enhances internal control. 
  7. Reporting and Analytics: Timely invoice management and reporting, combined with AI-driven analytics, enhance business intelligence relating to spend management and decision-making for cost reduction. 
  8. Scalability: Invoice automation software for accounts payable must be scalable to handle business growth, added complexity, and more entities. AP automation scalability enables the processing of a higher invoice volume and payment in large batches, with reduced hiring needs.
