Hope you're all enjoying the weather.

We certainly are...and as we've signed a tender with a major project builder, our future is now a little more certain...i hope.
We did however pay a 600 dollar deposit for soil test etc with another project builder, who we now don't want to build with and have now cancelled our tender aoppoint.
As we signed some drawings/price documents with them at our initial sales meeting, I was wondering can the project builder come back and invoice us for these drawings?
Thanks for any advice.
