Recognize and Report Phishing Scams

Be on the lookout for scam invoices
Did you receive a suspicious invoice, estimate, contract, or message from Square? If you don’t recognize it, don’t pay it. Invoice phishing scams are on the rise, and we want to keep you safe. Forward any suspicious message you get to, then delete it from your inbox.

What is phishing?

Phishing is an attempt by a fraudster to collect personal and/or financial information over email, phone, or via text message. These fraudsters typically get this information by verbally requesting it over the phone, by posting links or false phone numbers on social media sites, or by sending unsolicited emails or texts messages that direct recipients to enter personal information into fake websites or phone systems posing as real ones.
