GeneraTOR
The GeneraTOR will guide you through writing the different sections of a ToR / RFP. It will generate a word document with your saved information which can then be further refined and/or reviewed by others.
Below is a screenshot of the GeneraTOR. The left hand side allows you to navigate through the various sections of a ToR. Typically, a good ToR would include these sections and many organisations use them in their standard TOR template.
