Fill in the blank contract vs computer filled contract

For years I have been doing all my contracts on the computer. I would have a template and then change the adress, name, price, etc. for each client.

For this year, I was thinking about typing out my contracts on the computer and leaving blanks and then filling in the blanks while I am at the customer. I think this would be quicker and lock done jobs/contracts faster. What do you guys/girls think?
