Can claim lost business income due to discount product

Please let me know can a business claim lost revenue due to that month had on sale products.

For example: product price is $60, but it sales $50.

So can the business claim as lost revenue $10 ?

Thank you in advance.

Ok, I’ll chime in. No deduction.

It’s common to record the revenue as $60 then the $10 as discounts (subtracted from revenue) in the books. But the “net revenue" is $50 either way, and that’s often the only number carried over to the tax return. You can’t deduct ANOTHER $10 from the $50.
