Understanding the Why-How-When of Invoice Approval Workflow Automation

invoice approval automation

Invoice approvals are an integral part of every business, irrespective of whether they offer products or services. A clear and transparent invoice approval process is a must for maintaining good vendor relationships and accelerating invoice approvals. Manual, paper-based payment approval processes are prone to errors, duplication, and delays. The invoice approval workflow is made up of several repetitive steps that can be effectively automated with workflow automation software.

Businesses cannot afford to have subpar invoice approval processes without facing consequences like unanticipated liquidity shortages, unexpected cash crunches, and inaccurate cash flow forecasts. Paperless invoice approval systems offer better control and visibility into the invoice approval process and avoid delays in approval.

Invoice Approval Process at a Glance

Accounts payable is a critical business function that affects the business bottom line directly. Whether it is a single person accounting operating accounts payable or a large finance department handling financial transactions, a clear mapping of various steps is essential for streamlining the accounts payable process. The invoice approval process is at the heart of the accounts payable function.

If you want your business to succeed and establish reliable vendor relationships, timely vendor invoice approvals are a must. The first step to optimizing the invoice workflow is to familiarize yourself with the workflow. What is the invoice approval workflow? It is a checklist of steps/activities that need to be undertaken to validate and pay an invoice.

The invoice approval includes steps like information verification and approval before finally submitting the payment. At the end of the invoice approval process, invoices will be cleared and payment will be made to the appropriate parties.

The invoice approval process includes the following activities –

  • Verification of the invoice data by comparing it against the data in the receipts, progress reports, purchase orders, and other data
  • Request for additional information or clarification in case of any discrepancy
  • Request appropriate signatures to approve the invoice
  • Process the invoice payment and payout the money owed.

The invoice approval process begins when the buyer receives the supplier invoice. Once received, the invoice is sorted into the appropriate category and forwarded to the respective stakeholder for approval. Small and medium businesses usually have a member of the admin team to process invoices, while enterprise businesses have the accounts payable department to take care of invoice approvals.

Invoices are categorized into two types

The ones that have a purchase requisition or purchase order, and the ones that are not associated with any purchase order or request. The payment approval workflow comprises the following steps:

Creating an invoice 

For creating an invoice, all the relevant information should be captured and recorded in the document. Timely approval of invoices requires the capture of relevant information for payment, like total cost, number of units, and cost per unit.

Validation or PO matching

The next step of the process is to categorize the invoice based on the type of purchase. The validation step identifies and links other related purchasing documents like order receipts, purchase orders, purchase requests, and goods received notes.

Define exceptions

Invoices that do not go through the validation stage due to any discrepancy or missing information need to be forwarded to specific people who can fix the errors or furnish the missing information. Once the discrepancy has been addressed, the invoice is rerouted for approval.

Routing approvals

Validated and matched invoices are routed to the appropriate approver. The approver is chosen based on the information mentioned in the purchasing document, such as the PO number, department, or requestor name.

Processing payment

Approved invoices are forwarded to the finance team for further processing. Invoices that are approved are sent for payout, once payment is complete the invoice can be closed.

Why should you Automate the Invoice Approval Process?

The need for automating the invoice arises from the inefficiencies of manual invoice approval. Traditional invoice approval processes are filled with a number of inefficiencies and process gaps. Organizations that use manual invoice approval processes experience delays and fraudulent practices.

Here are 5 reasons why you should automate the invoice approval process:

1. Unexpected delays in approval

conventional invoice approval processes are characterized by delays in the review and approval of invoices. Manual processes are also riddled with bottlenecks

2. Lack of visibility

the stakeholders do not have visibility into the status of the invoice in a manual process. The lack of visibility into the status of invoices causes delays in approvals.

3. Lack of transparency

Manual processes are not standardized and depend more on human intervention. This decreases the transparency in invoice workflows.

4. Long approval cycles

any process that is driven by human efforts is ridden with delays and long approval times.

5. Excessive paperwork

Manual processes use a lot of paper-based documentation. Loss or damage to paper documents causes delays in the approval process.

Manual invoice approvals are ridden with all of the above challenges that slow down invoice approvals. An electronic invoice approval process addresses all these challenges and improves the speed and efficiency of invoice approval.

When should you Automate the Invoice Approval Process?

There are several reasons why you should automate the invoice approval process. Organizations looking to improve the efficiency of invoice approval and eliminate errors and frauds from the process must consider invoice approval automation.

Most organizations are still using archaic manual approval processes mainly due to the simplicity and minimal costs associated with manual workflows. Finance and procurement teams are so used to working on manual systems that they do not want to step out of their comfort zone and adopt automated invoice approvals.

When should a business consider automating its manual processes? There are some indications in business operations that must be taken as a sign to automate the invoice approval process.

Here are signs that indicate that the invoice approval process must be automated:

1. Time wastage

When too much time is wasted on reviewing and approving invoices, it is time that businesses consider automating their invoice approval process. Business processes comprise several repetitive tasks that are time-consuming and tedious. Accounts personnel spend several hours of their productive work time on routine, low-value tasks like invoice matching, following up on invoices, and tracking missing documents.

2. Misplaced documents

In large organizations that follow manual invoice processing, the issue of misplaced or damaged documents is very common. Accounts personnel waste a substantial amount of time searching for missing documents. Paperless invoice approval systems can relieve the team from the additional work of finding missing or misplaced documents. When incidents of missing or damaged paper documents are on the rise, organizations must consider digitizing the documentation workflow.

3. Delayed approvals

When invoice approvals are delayed, payments to vendors are subsequently delayed. Delayed payments to vendors affect vendor relationships adversely. This situation can get worse in large organizations where multiple approvers are involved and the visibility into who is responsible for which approval is blurred. Consistent approval delays are a clear case for invoice approval automation.

4. Exposure to fraud

One of the biggest challenges faced in manual invoice approvals is the risk of fraud and duplication. Manual workflows offer very less oversight and visibility into the accounts payable process. Compromised visibility opens up gates for fraudulent practices in invoice submission and approvals. Duplicate or fake invoices are on the rise.

Automating the invoice approval process is a tested way to steer clear of fraud. When the accounts payable department faces several instances of fraud in invoice processing, it is time to automate the approval process.

5. High error margins

Human errors in invoice processing can prove to be very costly for the business, resulting in invoices being underpaid or overpaid. Even errors in bookkeeping result in losses for businesses. High error margins in invoice processing not only result in loss of money and disgruntled vendors but also affect the auditing process adversely. When invoice processing errors are on the rise, it is high time you automate the process.

6. Missed cost-saving opportunities

Payment discounts are often offered by vendors to buyers that make early payments. When invoices are processed manually, buyers often miss out on such cost-saving opportunities. Automating the invoice processing workflow ensures that payments are done on time and buyers can avail of the early payment discounts on pricing. If you have missed payment deadlines and cost-saving opportunities, then it is time to consider automating invoice approval.

When your business faces any or all of the above issues in invoice processing, it is time to consider automating the invoice approval process and payment approval process.
