A higher willingness to calculate will result in more quotation requests. By submitting your own quotation via 12Build, you can be sure that this will be passed on directly in to your willingness to calculate.
For example, do you send your quotation by e-mail to the main contractor? Then you depend on the main contractor to add your quotation manually in that project. Of course it is also a good way to keep your own administration in order.
If you don't or the main contractor doesn't add the quotation (in the right way) in 12Build? Then your status does not change for this project. This results in a lower willingness to calculate and unnecessary mailings, where the deadline of the quotations is almost expired.
See in this article how to add your quotation in 12Build.
