A client purchased multiple packages totally thousands of dollars from my company, received the services, and then disputed the charges as 'unrecognized'. Square permits fraudulent chargebacks against your company.
People understand how to use it, so it's widely accepted as a valid method of payment and no one is nervous about using it (they should be!) I had to sit with my bank to file a dispute with Square, put a hold on all charges by Square, and start using an entirely different payment processor just to avoid Square stealing my money.
I provided the following to square: Her signed contracts, with an anti-chargeback clause Photos of us performing the services at the event, with her in the photos A chain of her emails, including an email after her event thanking us for job well done Despite this proof and legally binding contract, Square sided with her and removed the funds from my account.
