I think withdrawal function should include the balance check so that is not possible to withdraw if the balance is not enough

There's a problem moving it directly to the method, as the check would be executed at the end, so if the user has no balance, the job entity would have already been created.
There are many options here:

• Keep it separate, that way we can do the check at the beginning without duplicating it.
• If you want to add it inside the method, you could run the creation of the payment at the beginning, making the check.

IMO, we should keep them separately. This ensures that the balance is verified before any other operations are performed, preventing the creation of unnecessary entities and maintaining data consistency. Also, the createWithdrawalPayment method will remain focused on creating the withdrawal payment

IMO, withdraw function should for sure include a balance check.
About the order of payment entity and job entity creation, actually I think the payment should be created before the job entity, this way we avoid an edge case where we create the job and don't charge the user.
