SwiftStrike wroteAlright,
But one question though, shouldn't i submit taxes if i send invoices? or im in the clear?
If this client books is in Lebanon, he will need to have your مالية number which is a process freelancers go through so they can invoice legitimate business. If this is a small amount or the client is based outside Lebanon, I wouldn't bother going through this process and what taxing consequences might result from that.
Currently, I generate a virtual invoice using invoice-generator.com/
