Supplier Invoices & Cost Review Practical guide
An Unfamiliar Invoice? Verify the Vendor Before Anyone Pays
Pause and validate the order path
The short answer
An unfamiliar invoice can be a legitimate new service, an employee-approved order, a mistaken bill, or a scam. The FTC advises businesses to use clear approval processes and examine invoices, especially for unfamiliar companies or services.
How to approach it
Use a trusted vendor directory and order history, not payment instructions included in an unexpected message. Contact the vendor through a separately verified number or website before opening attachments or sharing account details.
- Match the bill to an internal request or purchase record
- Verify vendor identity through a known channel
- Escalate suspicious payment instructions and preserve the message
Could this affect your business?
- Can you trace this charge to an approved order, accepted terms, and a delivery or service record?
- Would your review catch the same bill, a changed pack size, or a fee that appeared this month?
- Can a second reviewer reproduce the comparison from the original documents?
