I try it but it gives me an error "Sum line different to amount"
what should i do in this case

Thanks,

Post the payment in accounting, not in sales.

I go to Accounting > Customer Payements then i select the client and add the amount but i still have the same error

Can you provide a screenshot, what are the log entries?
