A more thorough explanation:

Definition: Pass-along refers to costs that are chargeable to the buyer or lessee by the seller or lessor. It is also known as pass-through.

Example: A landlord may pass along the cost of property taxes to their tenants by increasing the rent. Similarly, a company may pass along the cost of raw materials to their customers by increasing the price of their products.

The examples illustrate how pass-along works in practice. In both cases, the seller or lessor is passing along their costs to the buyer or lessee. This is a common practice in business, where companies try to minimize their expenses by shifting some of the costs to their customers.
