It's possible to save your contracts as a PDF in Lifesycle, however, this is only possible with signed contracts. It's really simple to do.
First of all, go to operations >> contracts.
Then go to your completed contracts and find the contract you wish to save as a PDF.
Once you have opened the contract, simply click the box with the downward pointing arrow.
This will then open the contract in a separate page in which you can either print, or download.
