Let's suppose there's a customer who needs a software product and there's a custom software development company that is ready to implement this product. They agreed that the customer has to pay X (dollars) for the product.
Am I right, that there're two budgets here? The first one is of the buyer - X (dollars). But for the vendor the budget is not equal to X, it is much less than X (at least because the vendor needs to have some profit, rightso it can't spend all the sum X on implementing the project)?
