Fraudsters know one thing very well: businesses process invoices constantly. In a large company, hundreds of invoices pass through accounting departments every week. For small businesses, it’s easy for an invoice to slip through without deep scrutiny,especially when:
- The finance team is overwhelmed.
- The finance team is overwhelmed.
- The invoice looks legitimate.
- The payment amount seems "normal."
- The request comes from someone who appears credible.
Criminals exploit these moments. They forge documents. They impersonate vendors. They manipulate payment details. Sometimes they create fake companies from scratch, complete with professional websites and references.

What is invoice Fraud ?
Invoice fraud or Fake invoice is a deceptive practice where a person or group submits a false invoice with the intention of securing payment for goods or services that were never delivered, partially delivered, or grossly overpriced.
Successful invoice fraud is rarely a random act. It involves careful research, social engineering, and sometimes internal collaboration.
Fraudsters often:
- Study a company’s vendors and contracts to forge believable documentation.
- Monitor communications (e.g., through hacking or phishing) to time the fake invoice precisely during a busy period.
- Mimic real invoices by copying templates, logos, language style, and payment terms.
In some cases, fraudsters intercept genuine invoices during transmission altering only the payment details while keeping everything else identical.
10 Ways to Tell If An Invoice is Fake.
Invoice fraud thrives because it blends into legitimate business operations. The fake invoice often looks ordinary, expected, even urgent. That’s why having a checklist of red flags and the discipline to use it is critical.
1. Missing or Inconsistent Vendor Information
Legitimate businesses protect their brand and contact information. But fake vendors often rush setups, leading to sloppy or missing details.
What to look for
- Generic email addresses like Gmail, Yahoo, or Hotmail instead of company domains.
- Phone numbers that don't match known contact details.
- Company names slightly misspelled (e.g., "Microsof" instead of "Microsoft")
Tela Tip.
Always cross-verify the vendor's address and phone number against official websites or government databases, not just what’s printed on the invoice.
2.Strange Payment Instructions
Most businesses have consistent, registered payment channels. Criminals redirect funds to quickly launder money through hard-to-trace systems.
What to look for
- Requests for payment to personal bank accounts instead of corporate accounts.
- Sudden changes in payment methods (e.g., wire transfer instead of ACH).
- Foreign bank accounts without logical business reasons.
Tela Tip:
If payment details differ even slightly from previous invoices, freeze the transaction until you get written confirmation from a known, trusted contact.
3. Unusual Urgency or Pressure
Fraudsters create artificial panic to push you past your normal due diligence.They might demand immediate payment, claiming a "critical deadline" or "risk of service interruptionWhat to Look For:
Emails marked “URGENT” or "Immediate Payment Required." Threats of service disruption if the invoice is not paid within hours. Demands that bypass normal verification or approval steps.Tela Tip:
Build internal rules: The faster someone demands payment, the slower you move urgency should trigger extra verification, not shortcuts.4 Inconsistent Invoice Formatting
Most businesses have consistent invoice templates for branding and compliance. Fraudsters often stitch invoices together using random software tools.
What to Look For:
- Fonts, margins, and logo placements look unprofessional or vary from earlier invoices.
- File types inconsistent (e.g., previous invoices were PDFs but now it's a JPEG or Word doc).
- Missing standard sections like "terms and conditions" or "invoice reference number."
Tela Tip:
Set up visual memory cues: Every real vendor invoice should look like part of a brand family. If it feels "off," it probably is.
5 Pricing or Line Items That Don't Make Sense
Real vendor's invoices are based on a clear chain: quote → order → delivery → invoice. Fake invoices break this chain — adding, removing, or modifying details.
What to Look For:
- Billed amounts not matching agreed quotes or contracts.
- New items or services you never ordered.
- Extremely high or extremely low quantities.
TelaTip:
Always tie invoices back to purchase orders.No matching PO? No payment.
6 Missing or Invalid Tax Information
Registered businesses must meet legal invoice requirements. Fake invoices often fudge or omit tax details to avoid scrutiny.
What to Look For:
- Missing VAT/GST numbers (where applicable).
- Fake or unverifiable tax IDs.
- Incorrect tax rates or calculations.
Tela Tip:
Use official tax authority websites to validate any unfamiliar tax numbers.
7.Poor Language and Spelling Errors
Professional businesses invest in polished communications. Fraudsters working quickly (and often internationally) leave language clues behind.
What to Look For:
- Obvious grammar mistakes or awkward phrasing.
- Misspelled words, especially technical terms.
- Incorrect currency symbols or decimal separators.
Tela Tip:
Develop a zero-tolerance policy: if an invoice looks sloppy, it deserves deeper verification regardless of amount.
8 No Matching Contract or Purchase Order.
In legitimate transactions, there’s always pre-existing documentation supporting the invoice.
What to Look For:
- Invoices appearing without any prior agreement or order.
- Vague service descriptions (e.g., "consulting services rendered" without project details).
- Missing project codes or internal reference numbers.
Tela Tip:
Train your team: "No PO, No Pay." Every invoice should trace back to an authorized purchase or contract.
9 Suspiciously Small Invoices
Fraudsters test systems with small invoices first, knowing that small losses are less likely to trigger audits.
What to Look For:
- Tiny amounts (10000–50000) that fly under manager approval thresholds.
- Vague supply charges like "office supplies," "miscellaneous services," etc.
Tela Tip:
Randomly audit even low-value invoices, it sends a clear internal message: Every dollar is checked, no matter how small.
10 Unverified Changes in Bank or Payment Details
Often, payment redirection is the final move after months of careful setup, where scammers have studied communication patterns and timing to make their request seem legitimate.
What to look for
- Emails from "vendors" notifying about new payment accounts.
- Requests to update banking information without formal notice.
Tela Tip:
Create a strict policy: Any change in payment instructions must be verbally confirmed with a previously verified vendor contact.
