United Swiss Co$.,$ a Swiss company based in Basel, Switzerland, made records, tapes, and CDs$.555,$ a New York distributor has been doing business with United Swiss for over $10$ years. $555$ ordered goods from United that were delivered in ten shipments with written invoices. The invoices noted that payment was due in $30$ days and that claims about problems must be made within two months of delivery. During the ten years of doing business together, any time there was an issue, $555$ provided United with notice within the two$-$month time frame. Industry guidelines allow $60$ days to make payment, and three months to provide notice of any problems. $555$ objected to the terms of sale for the first time during this transaction, and refused to pay. $555$ claimed there was no written contract in violation of the statute of frauds and it was trade custom in the industry for distributors to be allowed to return any defective goods for credit. United claims that the terms of the agreement were violated, and they sued for payment. According to Article $2$ of the UCC, who is right?
