Does the customer have the right to use developments that were rejected?

Question

Design

Let's say a customer comes and says you need a logo/website/application or anything else. The process starts, options are riveted, folded back, new ones are made, a suitable one is found, approved, finalized, passed - everything is OK. Then some time passes and then the customer declares that everything is cool with that project, but we use the version of the logo / site / application that we did not approve in another project. The question is, do we have the right to demand payment for this option, or do all the developments during the workflow go to the customer?

Answer 1

This question is about your contracts that you have drawn up with the customer.

Answer 2

Theoretically, the results of intellectual activity are yours, unless otherwise stated in the contract.
You need to look at how it is written in your contract, payment for one logo / site / application, or, for example, "provision of services for the development of logos."
As for payment, if everything is written correctly in the contract, then theoretically you can present an invoice, but there will be difficulties with substantiation, because a) there is no contract for everything else b) the second logo is worse (cheaper) than the first, you won’t ask for a similar price and. etc. i.p.
It turns out that when you demand payment, you are 99% likely to end up in court. Without a contract and with probabilistic justifications for its price.

Answer 3

to be sure, next time make it a clause of the contract

Answer 4

so you did the same options for the money and he has already paid for everything.

Answer 5

If we did not agree on this, then at your request I must stop (in good human and business relations).
