I would like to show you how I make my personalized contracts.
I thought that for this an update would be needed, but it is not necessary, I create my contracts in English and Spanish.
What we need is a text editor program (Word, Notepad, Sublime Text, etc).
We need to configure our contracts section here: https://soundgine.com/control.php?f=contracts
and create the Templates for the contracts.
Every time you need to customize it, you would have to copy the contract text, (Important!) Save a copy of the template text.
Enter your text editor and look for the "Replace" function, search for the value "%BUYER%" and replace all the values with the name of the buyer.
In the same case to change the value of %BEATNAME%,%DATETIME%, %LICENSE% or %PRICE%.
After you have customized your entire contract, update and create random Previews until you get the desired license.
I know it's something simple, but it works very well, if you want to modify something in your contracts.
