Pay with debts is a rather surprising but effective and lawful form of buying goods or services at a reduced price. Debt and its documented costs, including statutory interest for delay, constitute a specific financial value and can be used to offset payments. If someone buys such a debt for a smaller amount than its real value (eg 70% of the value of the debt or for the amount of the debt without additional costs), it has a financial claim against the indebted company that it can satisfy by paying for services or goods. This is a frequently used method, eg in the construction industry. The principle of the method of paying with debt is presented in the graphic below.
