The plaintiff and defendant, whose directors were close friends, entered into business dealings. Plaintiff sold coal to defendant at defendant's request at a discounted price of $50 per tonne. Defendant made initial cash payments totaling $12,000. According to a reconciliation signed by both parties, defendant had drawn coal worth $92,268 and provided transportation services worth $134,064, less fuel worth $77,934.15 provided by plaintiff, leaving a net transportation charge. After offsetting the transportation charges against coal purchases and deducting the $12,000 cash payment, $24,148.15 remained outstanding. Defendant's representative signed the reconciliation and wrote "to be offset" on it. The parties disagreed on the nature of their contract: plaintiff claimed it was a sale with payment due in cash, while defendant argued it was a barter/exchange agreement whereby the debt would be discharged through provision of transport services. Defendant admitted owing $24,148.15 but disputed that it was payable in cash.
