Three brands
Give every client this design in their own brand.
Add a client's logo, colours, and fonts in one step, and you've got a file that looks made just for them, with no new design to build.
About this design
What you can make with it.
When a client wants a full price before they say yes, send one page that lists each part of the job with its price. The VAT and the total add themselves up, and the total sits in a bold tab. Below it are your plan week by week and a place for you both to sign.
Your details
What you can change.
These are the words and numbers you swap for your own. The design stays the same.
