Met a very bad paymaster, who wants things immediately. For the previous stages of work completed, it took a lot of effort to get them too pay. Currently, I'm at my last stage where i am supposed to provide them with my working files to check through before they are willing to pay. I have a strong suspicion that they would either drag the payment or refuse to pay after giving them the files.Is there a way where i can protect myself by setting a validity period for the files i give to them? Or any other way to protect myself? (giving them PDF files is not an option, as they are expecting working files with links.)
Thanks very much.
