In the paper the problem of the supply chain expected profit maximization using a coordinating contract in condition of one of the counterparties being financially constrained is considered. The solution is derived for a two-echelon supply chain assuming product demand being distributed as uniformly. A revenue-sharing contract with bank financing and a modified revenue-sharing contract with trade credit are explored. It is stated that none of them is coordinating, as supplier's expected profit maximum is not attained. Conditional supply chain coordination using a modified revenue-sharing contract with trade credit is considered if supply chain and retailer's expected profits are maximized and supplier's expected profit exceeds that under the modified wholesale-price contract with trade credit and the revenue-sharing contract with bank financing. It is proved that the problem of the supply chain expected profit maximization under the assumptions made can be solved using a modified revenue-sharing contract with trade credit financing.
