Do you know that 39% of invoices are paid late in the United States, and 61% of late payments result from invoicing errors?

Even more, 82% of finance departments report being overwhelmed by the number of invoices they have to process daily and are further exhausted by the variety of formats these invoices are received in.

One thing is for sure from these facts, dealing with invoices can be pretty frustrating, and you're definitely not alone in your struggle.

But the question is, what's to be done?

We have the answer for you! Keep reading to find out about:

What is Automated Invoice Processing?

Automated invoice processing involves scanning, extracting, matching, and validating relevant invoice data and inputting it into your ERP or accounts payable system.

Invoice automation software eliminates manual intervention, except in those special cases where a human touch is required, greatly reducing the burden on accounts payable and finance teams.

It improves cash flow, drives additional savings, and helps procurement organizations make the most of dynamic discounting opportunities.

Here is an example of automated invoice processing steps:

  1. Extracting an invoice, generating it from an existing purchase order, or creating it from scratch;
  2. Automated 3-way matching against the purchase order and receipt;
  3. Resolving any irregularities (e.g., mismatched PO numbers, incorrect line items, etc.);
  4. Routing the invoice to a manager or senior executive for approval;
  5. Invoice approval through software or email;
  6. Issuing payments to vendors;
  7. The software updates invoice information for reporting purposes and integrates it into the ERP system.

These steps may vary a little depending on yes/no response options.

However, regardless of changes in the flow, e-procurement software users save more than 50% of their time on invoicing.

Manual Invoice Processing Challenges and How Automation Solves Them

Without the proper accounts payable technology, it's difficult for organizations to maintain an efficient invoicing process.

According to Levvel Research, manual AP processes' biggest pain points are manual data entry and approval workflow, lost or missing bills, duplicate invoices, etc.

But the good news is that those problems are easily solved if good procurement software is near at hand.

Let's review some of the challenges and see how you can fix them.

Manual Data Entry

It takes a lot of time to process invoices manually.

Depending on the number of bills, your team can easily spend hours on data entry alone and end up overpaying or underpaying them.

In fact, 38% of small business employees admit that data entry is their most time-consuming task, and 27.5% of companies manually input incorrect data into their systems, causing tax and accounting mistakes.

The solution:

Companies can leave the manual steps behind by using automated invoice processing software to manage the data extraction and validation processes.

For example, by using Precoro, you can reduce manual data entry by 80%.

With Xero, NetSuite, Quickbooks, and custom integrations, all your invoice information is automatically transferred to your accounting system, letting you focus on more productive tasks.

Missing Invoices

It's easy to lose or forget about invoices when they are moving around the business in paper or email form.

The bill might be missing because it was addressed to the wrong department or person, caught in spam filters, accidentally deleted, etc., preventing it from being tracked down and paid.

Lost invoices can cause serious problems with vendors and hurt your cash flow or even force you to start the invoice processing over again.

The solution:

Invoicing system not only automatically emails or sends bills directly to the right person for taking action but also alerts you when the bill has been approved, sent for revision, canceled, if it's ready for payment, etc.

Make sure the correct email is associated with each supplier's account and that you regularly check for "unviewed" invoices.

Using Precoro invoicing solution, you always have all the important information available in the system.

You can track bills by their status and use real-time reporting to ensure that no invoice was lost.

Manual Approval Routing

50% of companies spend an average of 10 to 25 days approving invoices manually.

The process can take even longer if multiple approvers are involved, and it isn't clear who is responsible for the approval or at which stage of the accounts payable workflow the invoice is currently in.

The solution:

With invoice processing automation software, such as Precoro, you can create a workflow that automatically routes invoices to the right approver.

Precoro customers get 2,5x faster approvals and save up to 95% of their time.

Users can approve or reject invoices anytime and anywhere through the specific Invoice page, Preview, or email.

You can add as many approval steps as needed, get smart notifications, and create custom workflows that will suit your business needs.

Invoice to Payment Matching

In 2-way matching, the PO and invoice information is verified to match within your tolerances.

When doing it manually, invoice-to-payment matching can be extremely time-consuming.

But it's still an important step for your business as it eliminates discrepancies in the purchasing process, reduces payment fraud, and ensures compliance.

The solution:

With Precoro invoice approval software, you can integrate your workflow with your accounting systems and perform this matching automatically.

It ensures that you only pay what you owe, no more and no less.

Slow Processing

Each pair of hands that handles the paperwork increases the risk of an error or loss of the document and slows the processing time.

Manual processing often results in invoices being delayed and dissatisfied suppliers persistently asking about their payment status.

Payment delays can cause a chain reaction of negative consequences, such as commissions for late payment and delayed shipment of goods.

Slow payments can also affect your business's credit rating, further reducing the ability to obtain favorable terms from suppliers and creditors.

The solution:

Eliminating piles of paper invoices and manual data entry can drastically reduce processing time and error rates.

Automation can speed up the processing cycle by 73%, allowing you to focus on more strategic tasks.

How does it work:

  • You don't have to re-enter the invoice data into your ERP or accounting system. Procurement software automatically transfers it.
  • There is no need to send emails or wait for the team meeting to approve documents.
  • 3-way matching is automated and takes a couple of minutes.
  • You always have access to the current status of your bills.
  • Fewer errors — less time spent fixing them.

Benefits of Automated Invoice Processing

We've already discussed some of the advantages of AP automation in the last section.

But let's dive deeper into how your company can benefit from it.

Lower AP Processing Costs

By switching to e-invoicing, you can reduce labor expenditures, printing and mailing overhead, and interest and late fees.

According to Levvel Research, AP automation helps save $13 on average for each invoice processed.

For companies that process 500 invoices per month, that leads to an annual savings of $78,000.

Time Savings

The accounts payable process can take 30 to 90 days per invoice.

With an ap automation solution, you can approve an invoice and do a three-way matching in minutes without human intervention.

Improved Accuracy

When working with bills manually, you can expect various errors, such as entering an incorrect price, sending out the wrong invoice, duplicating it, and more.

But with invoice automation, however, you can streamline business processes and cut down on these costly errors.

According to a survey by the Shared Services Outsourcing Network, companies that automate their accounts payable processes can expect to reduce costs and errors by 70– 85% during primary invoice processing tasks.

Better Relationships with Suppliers

Automated invoice processing helps your business make timely or even early payments and improve supplier relationships.

This is beneficial because:

  • You can reduce the number of suppliers needed and thus simplify the buying and budgeting processes, creating significant potential savings.
  • If any order issues arise, the strong relationship between the organization and supplier will make it simpler to solve them.
  • Effective feedback between the two parties will improve operations and streamline the supply chain.
  • It reduces issues with availability, quality, and delays in supply.

Increased Productivity

Invoice automation solutions increase your employees' productivity by boosting accuracy and reducing the time spent processing invoices.

Since the process is optimized, they can focus on more important tasks.

Better employee productivity also contributes to lower overheads and higher revenue. In short, automating the invoicing process is a great way to boost your bottom line.

A Few Tips to Consider Before Switching to AP Automation Software

We have already discussed how automation helps cope with common accounts payable pain points, its advantages, and what features the best process automation solutions have.

Let's also see how you can get the most out of your automated invoice processing implementation.

Analyze Your Current Invoicing Process

Before moving to your company's better future, you should also review what went wrong in the past.

Analyze your invoice handling process, and see where inconsistencies, errors, or bottlenecks occurred.

It may also help to answer these questions:

  • Who receives bills, and how they're verified?
  • In what form do they come in (electronic or paper invoices)?
  • How long does it take to process invoices, and who is responsible for that?
  • Did you have delays in the invoice payment process? Why did that happen?

Make sure to get a complete picture of your payable process so that you can find the right tool for your business needs.

Centralize and Standardize Invoice Management

Ask your suppliers to send invoices to one central location or electronic address.

Also, ensure to capture the invoice data and index bills as soon as they are received.

Then try to develop clear policies on bill handling:

  • What are the matching criteria and tolerances?
  • When do you want to take and not take early payment discounts?
  • Who may approve invoices within the company, and what is the approvers' hierarchy?
  • What happens when the discrepancies between incoming invoices and corresponding purchases occur, and what's the resolution workflow?

Knowing exactly how bills should be processed within your company will help you outline processes that the accounts payable automation solution will then automate and streamline.
