Step-by-step explanation:
Services such as those offered by DollarDog that make BidBuy's services more valuable for customers who use the services of both companies are best described as complementors. Complementors are goods or services that are often used together, so that consumption of one enhances consumption of the other. In this case, DollarDog's services complement BidBuy's services, making them more valuable for customers who use both.
For example, if BidBuy is an online auction platform and DollarDog offers a price comparison tool for online shopping, customers who use both services can benefit from the combination of features. By using DollarDog's tool, they can find the best prices for products on BidBuy, enhancing their overall shopping experience.
In contrast, substitutes would be goods or services that can be used in place of each other. Rivals would refer to competitors in the same market, and suppliers provide the inputs or resources necessary for a company to produce its goods or services.
