Automadic form creation

We currently have template documents in word document format. We need a software program written so that we only have to enter the customers information once and it will fill it out in all the relevant places on the below documents. (EG: so we dont have to go through the documents and enter their name 10 times etc.) The following are the forms we have: -customer contract template (3pages long) -port form (2pages long) -support agreement (1 page long) -agree to purchase contract (5 pages long)
