Your tender graphic presentation is the equivalent to a storefront for your business
Imagine driving to site in a HOT PINK scooter with crazy flashing LEDS and the front and rear lights falling off...
What image do you think that you would portray to your clients?
Your professional image is incredibly linked to how clients perceive you.
The way that you represent yourself through capability statements and tender collateral is a direct perception of you - and it is highly visual!!
Outstanding design often has many layers of intricacies such as margins, consistency, scale, repetition, colour choice, correct font choices etc that require professional skills and cannot be replicated by junior, untrained professionals.
Always use a design professional and don't forget that your submission collateral is the equivalent of a storefront.
It should be a document that you are proud of.
