NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
Please don't start this again 
Why not?
Fantastic entertainment.
Think I finally got it right anyway.

Total sales + 15% + 5.5%, the 5.5% the bit that is payable, less the vat incured on my new van, but ONLY if its total value BEFORE vat was over ?2000,
anything UNDER ?2000 purchase price for start up reasons HAS to be claimed on the first vat return only, but anything OVER ?2000 purchase price exc. vat can be claimed for anytime in the future.
Have I made that quite clear do you think?
