Financial management is the most critical operational element of an organization. The financial department within a company is responsible for the accurate and timely recording, management, and reporting of all necessary financial information pertinent to the firm’s operations. Tucked away in the balance sheet is one of the most crucial financial parameters to judge a company’s financial viability - the Accounts Payable.

Accounts payable recognizes the sum that an operational organization needs to pay to its vendors or suppliers for services secured or goods purchased - including finished goods or raw materials. The process of verifying and registering accounts payable is complex - starting from the issuance of a purchase order to invoicing and vendor repayment. Also, the process was subject to the pitfalls of manual data entry and management, viz. human errors and rampant fraud. At this juncture, innovation in the accounts payable industry (in the 20th century) resulted in the rise of accounts payable software.

It will also clarify how businesses can gain a competitive advantage in their respective industries with automated accounts payable software.

Due to the intrinsic nature of accounts payable in an organization’s financial and operational stability, poor accounting management tends to have disastrous consequences for any business. Some of the biggest challenges introduced by faulty accounts payable management are as follows: 

  • Hard-Hitting Financial & Time-Wastage Costs Caused by Account Payable Data Entry Errors
  • Poor Vendor Relationship Management
  • Lack of Automation Leading to Slower Processing and Payout Cycles
  • Inefficient Document Storage - Resulting in Lost Records
  • No Transparency or Audit Trails in Accounting Processes Resulting in Duplicate Payments 
  • Rampant Fraudulent Practices Owing to Lack of Accounts Payable Regulations
  • Complex Billing Practices Leading to lowered trust between vendors, suppliers, and organizations  

Challenges of Accounts Payable Software

What is an Accounts Payable System?

An accounts payable system or Accounts payable automation software is a suite of digital tools and applications that helps organizations accurately record and manage all facets of their accounts payable process. Automation is the focus of accounts payable software. The AP automation software increases the efficiency and accuracy of the financial department by removing the unpredictability errors caused by certain administrative aspects of account payables recording - viz. Invoicing, data extraction and entry, and purchase order (PO) reconciliation, besides other processes. Through accounts payable processing software, vendor management becomes simplified, while it is easy to track payments and follow up on necessary approvals through an audit trail.   

Using accounts payable systems is straightforward. They also provide a much-needed fillip to organizations looking to scale up their operations while enforcing appropriate accounting standards and principles diligently. 

Competitive Business Advantage Through Automated Accounts Payable Software

Accounts payable and receivables software provide a significant fillip to an organization’s operations. Automating various tasks in the accounts payable process (above) helps streamline and simplify complex billing procedures - translating to time savings and labor efficiency improvements. Automation also provides a significant cost advantage. Organizations can now invest less in labor capital and other expenses, complementing cost-saving measures. 

Fast billing processes and shortened payment cycles will mean strengthened supplier relationships. As seen in many instances, good vendor management fast-tracks purchasing approvals, increases organizational output, and shortens time to market for products, giving organizations a definitive competitive edge. Reporting and analytics dashboards help pinpoint account payable trends and patterns help businesses further optimize process workflow. 

Recording Invoices also provides organizations with a significant advantage. It reduces the chances of duplicate payments. A benchmarking assessment by APQC suggested that the range of duplicate invoices from among those organizations polled was between 0.8 percent and 2 percent. The lesser the duplicate payments, the better firms can reign in costs for enhancements elsewhere. Accounts payable automation software also helps businesses extract exact data whenever needed. It means organizations can make quicker decisions and act fast on available information to gain significantly.
