Paradigm Real Estate Solutions entered into a contract to have a company brochure designed. After they approved the final brochure and said they were happy with it, they stated their intention not to pay for the content-writing, thereby placing them in breach of contract.
In an email, they said they were only willing to pay a portion of the invoice, but before they would send a payment, I would have to agree to accept this payment as a full and final payment. Using coercion in this way to induce someone to enter an agreement is one of the definitions of extortion.
