Whether you are a small business owner or an executive of a large enterprise, the risk of encountering a scam is alarmingly high today. In 2023 alone, 96% of US businesses became the target of at least one fraud attempt.

Among the deceptive schemes companies frequently experience, invoice fraud is one of the most common. 

If you deal with vendors regularly, you are bound to face this type of scam at some point in time.

However, by understanding the critical red flags and taking effective safety measures, you can significantly increase your chances of evading an invoice swindle. 

6 Signs of Invoice Scam

An invoice-related scheme can take a variety of sophisticated forms.

For instance, it could involve a fraudulent vendor sending you a duplicate invoice or charging you extra for items you have not requested.

Sometimes, scammers could direct a payment to one of their accounts by impersonating a legitimate vendor and requesting your business to alter their payment details.

Your employees could also siphon money by creating fake vendor invoices.

The complexities involved can make the prospects of detecting invoice scams seem incredibly bleak. However, certain telltale signs could easily give them away, enabling you and your team to avoid falling victim.

Here are the common signs to watch.

• Discrepancies in Details

This is the number one warning sign of invoice-related financial fraud.

But what type of discrepancies could you come across? You might receive a request for a bank detail change from an email address different from the one a vendor normally uses. Or there could be slight irregularities in the invoice, such as differences in the format, logo, or even contact information.

You may also notice inconsistencies in the purchase order, goods received note (GRN), and invoice.

All these should ideally raise alarm bells that something is amiss.  

• No Itemized Breakdowns

Legitimate vendors often provide a detailed description of what they are billing you for, breaking down fees by each item.

Dishonest vendors, on the other hand, will indicate a total amount with little details about what it covers. This allows them to deceptively inflate the invoice by sneaking in a few extra charges.

• Round Figures

In most cases, it is rare for invoices to carry round figures, such as $1,000 or $10,000.

If they do, you are likely looking at a fraudulent document.

• Sudden Changes in Vendor Information

Has a vendor suddenly dropped you an email or SMS requesting you to send a payment to a different bank account? If so, you could be dealing with a scammer in disguise. 

• Unusually High Volumes of Invoices

When you notice a sudden influx of payment requests, investigating them is important.

Sometimes, it could be due to a new project that involves lots of supplier payments. But you can’t overlook the possibility of invoice fraud.

• Urgent Payment Requests

Scammers frequently use undue pressure to manipulate employees into making rushed payments without taking the time to verify information. 

Preventing Invoice Fraud: The Essential Measures to Adopt

So, what can you do to protect your business from the risks of invoice-related swindles?

Introduce Air-Tight Policies

With the right systems and processes, you can significantly minimize the chance of falling prey to fraudulent advances.

For example, set up standardized processes for authenticating suppliers, validating invoice details, processing payments, and changing vendor information.

Communicate the relevant policies to vendors to manage expectations and ensure they follow the set procedures.

In addition, establish data-protection policies, document information, and conduct periodic audits.

Train Your Staff

Many businesses lose millions of dollars to invoice fraud, primarily due to human vulnerabilities and oversight.

Understandably, your employees have a key role to play in protecting your organization from scams.

For this, they require regular training.

So, educate them about the basics of invoice fraud—from different scam techniques to steps that could help detect and prevent them.

Also, equip your team with practical measures and tools to make better decisions. For example, teach them how to identify email phishing and verify vendor information with a reverse search on Nuwber.

Assign Responsibilities

Human errors and oversight often arise when there are overlaps in responsibilities. You can minimize this by defining job roles and creating detailed job descriptions that hold each employee accountable for specific tasks.

Don’t forget to set up KPIs and tracking mechanisms.

Integrate Automation

Advanced technological tools, especially in the area of automation, can significantly help eliminate human error. By automating repetitive tasks, you can also improve accuracy and achieve greater efficiency in your vendor processes.

You can even use AI-powered analytical tools to track data in real time and monitor internal workflows, including order placement, goods delivery, invoice processing, and payments. Such systems could help detect anomalies, such as sudden spikes in invoice volumes, and alert you to potential issues, enabling you to take timely action.

Implement Vendor Screening

If you are not careful, dishonest vendors could swindle money from your enterprise for years.

However, you can identify such individuals with a robust pre-screening process.

As part of this, implement a standardized documentation procedure to get to know your vendors. Ensure all information is authenticated with a thorough background check, references, and site visits, where necessary, before you sign up a supplier to your vendor database.

Tighten Security

Strengthening the security of your digital and physical business environments is imperative for preventing and mitigating the threats of invoice fraud.

For example,

• Set up access controls to protect your assets by preventing employees and other individuals from freely entering specific areas of your office premises.
• Adopt strong passwords to guard digital data in files, devices, and online accounts.
• Apply biometric verifications and multi-factor authentication.
• Opt for anti-virus software and firewalls to protect your security infrastructure from malware attacks, hacking, and other unwelcome intrusions.
• Use secure, password-protected internet networks with VPNs.

Key Takeaways

Each year, invoice scams swindle millions of dollars from businesses, both large and small. So, knowing how to identify them and taking preventative steps is essential for protecting your organization from needless financial losses.

Discrepancies in invoice details, lack of itemized breakdowns, the use of round figures, and an unexpected influx of invoices could often give away invoice scams. Sudden requests to change vendor information and undue pressure to process payments are other warning signs to watch.

However, with air-tight policies, staff training, detailed JDs, process automation, vendor screening, and security controls, you can minimize the risks of invoice fraud to a significant extent.
