How long does it take to write a tender response?

Tender open periods vary from 2 weeks for local government tenders to 4-6 weeks for state or commonwealth government tenders.
Obviously, larger projects can have much longer open periods than this depending on complexity.
In order to do a good job, we need all of the open time available. For new clients, we need at least 2 weeks.
For clients we have worked with before, we might be able to do the work in less time depending on the complexity of the tender. Less than 1 week is very challenging.
