The bid is a number in an email
The work is right and the price is fair, and it arrives as three lines of text that look like every other quote in the inbox. Get the proposal written as a real document instead, headings and tables and all, filed as editable Word with a matching PDF so you can change a line before you send it.
There is no brand to start from, only a website
You never hired a designer, so there is no logo file, no color list and nothing to hand a template. Your Brand Kit is built from your own website the moment you sign up, its fonts, colors, logo and voice, and your homepage is already filed in your Gallery, so the first piece comes back in your own look with nothing else to fill in.
The next job wants the same thing in a different shape
The words are already written, in the proposal that won last month or the page about the service. Turn that into the sell sheet, the post or the email the next bid needs, built from what it already says, instead of writing it again.
