Fraud does not just happen to big corporations. It happens to businesses like yours — and it is more common than most owners realize. Small businesses lose an average of 5% of their annual revenue to fraud, and nearly half never fully recover. For a business bringing in $200,000 a year, that is $10,000 gone before you even notice.
The good news is that most fraud is preventable. The key is knowing what to look for before it happens to you. Here is a breakdown of the most common types of fraud targeting small businesses today, and the practical steps you can take to protect yourself.

Payment and Invoice Fraud
Payment and invoice fraud works by exploiting the routine nature of your billing process. You receive what looks like a legitimate invoice, process it without close scrutiny, and the money lands in a fraudster’s account instead of your vendor’s.
The most common schemes include:
Fake invoices. Scammers send professional-looking bills for goods or services you never ordered. Amounts are often kept low enough to process without triggering a second look.
Vendor impersonation. A fraudster poses as one of your real suppliers, provides updated banking details, and redirects your next legitimate payment to their own account. By the time you notice, the money is gone.
Business Email Compromise (BEC). Someone impersonates your accountant, a senior employee, or a known vendor over email and requests an urgent wire transfer or payment update. The email looks real. The urgency feels legitimate. BEC alone caused $2.77 billion in U.S. losses in 2024, making it one of the costliest fraud schemes targeting businesses today.

How to protect yourself:
- Verify any payment change request by phone before acting on it, using a number you already have on file — not one included in the email itself
- Require dual approval for wire transfers or payments above a set threshold
- Cross-reference every invoice against your purchase records before paying
- Use invoicing software that creates a clear, traceable record of every transaction so anything unusual stands out immediately
Finli’s platform generates verified, trackable invoices and payment records for every transaction, making it much harder for fraudulent invoices to blend in with your legitimate billing history.
Phishing, Smishing, and Cyber Fraud
You have probably heard of phishing. But today’s attacks look nothing like the obvious suspicious emails of years past. Fraudsters now use AI-generated messages that closely mirror real business correspondence — and they are harder to spot than ever. Nearly 80% of businesses experienced actual or attempted payment fraud in 2024.
Here are the three delivery methods you need to know:
Phishing arrives by email, directing you or an employee to click a link, enter credentials, or download an attachment that installs malware or harvests login information.
Smishing does the same via text message. U.S. businesses and consumers reported $470 million in losses to text-based scams in 2024 alone.
Vishing uses phone calls, increasingly enhanced with AI voice cloning to impersonate someone you trust — a bank representative, a vendor, or even a colleague.
Once a fraudster has your login credentials, they can access your accounts, redirect payments, steal customer data, or lock you out of your own systems. The average cost of a cyber incident for a small business has reached $56,600 — a number that can derail your operations if you do not have the right coverage or reserves in place.
And here is the uncomfortable truth: 60% of small business owners say cybersecurity is a top concern, yet most are too small to hire dedicated IT staff. That gap is exactly what fraudsters exploit.

How to protect yourself:
- Enable multi-factor authentication (MFA) on every account that supports it, starting with email, banking, and payment platforms
- Train anyone who handles your finances to recognize red flags: unexpected urgency, unfamiliar senders, requests to verify credentials, and links that do not match the sender’s domain
- Never share passwords or banking information over email
- Keep all software and devices updated — outdated systems are a common entry point for attackers
Finli is SOC 2 compliant, meeting rigorous standards for data security and confidentiality. That means your customer payment data stays protected even if fraudsters are actively targeting your business.
AI-Powered Fraud: The Newest Threat to Your Business
Fraud has always relied on deception, but artificial intelligence has made that deception significantly more convincing. Fraudsters are now using AI tools to generate emails that read like real business communication, clone voices to impersonate people you know, and create fake videos of executives authorizing payments. AI-driven scams are projected to result in $40 billion in losses by 2027 — and small businesses are not immune.
What makes AI fraud particularly dangerous is that it removes the traditional red flags you have been trained to watch for. Poor grammar, suspicious formatting, and generic greetings are disappearing from fraudulent messages. A scammer can now clone your accountant’s voice from a short audio clip and call your bookkeeper with payment instructions that sound completely legitimate.

The most common AI-enabled schemes targeting small businesses right now include:
AI-generated phishing emails that mimic real vendors, banks, or colleagues so accurately that even careful readers get fooled.
Voice cloning scams where fraudsters use a few seconds of audio — pulled from a voicemail, a video, or a social media post — to impersonate someone you trust and request urgent action.
Deepfake video calls used to impersonate executives or business partners during virtual meetings, authorizing fraudulent wire transfers in real time.
How to protect yourself:
- Establish a verbal confirmation policy for any payment request that comes in digitally — even if the voice or face looks familiar
- Create a code word system with your team or key vendors for verifying high-stakes requests
- Be especially skeptical of any communication that creates urgency around a payment or account change
- Limit the amount of audio and video your business publicly posts of yourself and key employees, as this is the raw material fraudsters use to build convincing fakes
Employee and Internal Fraud
This one is harder to think about. But if you have employees — or even just one person helping you manage finances — internal fraud is a risk you cannot afford to ignore. 42% of fraud in smaller organizations is enabled by a lack of internal controls, and small businesses suffer a higher median fraud loss than larger companies as a result.
Common schemes include payroll fraud such as falsifying hours or adding ghost employees, expense reimbursement abuse, and skimming cash before it gets recorded. It is also worth knowing that 89% of occupational fraud cases involve first-time offenders — meaning this is not just a risk from people with a history of dishonest behavior. Pressure, opportunity, and a lack of oversight create the conditions. Remove the opportunity and you remove much of the risk.

How to protect yourself:
- Separate financial duties so no single person controls the full cycle from invoice to payment to reconciliation
- Review your bank statements and payment records yourself on a regular basis rather than delegating it entirely
- Use accounting software that creates a clear audit trail, and reconcile it against your payment platform regularly
- Have an outside bookkeeper or accountant conduct periodic reviews — a second set of eyes catches what familiarity misses
Real-time payment visibility tools, like those built into Finli’s dashboard, give you a clear record of every transaction as it happens. When nothing can be processed without leaving a trace, internal fraud becomes significantly harder to conceal.
What to Do If Fraud Happens to You
Even with strong protections in place, fraud can still occur. If you suspect you have been targeted, act quickly.
- Contact your bank immediately to report unauthorized transactions and request a freeze if needed
- Document everything: emails, transaction records, timestamps, and any communications related to the incident
- Report the fraud to the FTC at reportfraud.ftc.gov and, for cyber-related crimes, to the FBI’s Internet Crime Complaint Center at ic3.gov
- If customer data was compromised, notify affected customers promptly
- Check your business insurance policy — some coverage includes fraud and cybercrime losses
After a successful fraud attempt, more than half of businesses are unable to recover the funds lost. That reality makes prevention far more valuable than response.

Takeaways
Protecting your business from fraud does not require a big budget or a dedicated security team. It requires consistent habits — reviewing your accounts regularly, verifying payment requests before acting on them, and making sure the tools you use for invoicing and payments are built with security in mind.
Most fraud succeeds not because business owners are careless, but because fraudsters are skilled at blending into the routine. The businesses that catch it earliest are the ones that have built simple controls into their daily operations, so that anything out of the ordinary stands out before it costs them.
