That 2.5% cut

People who say the VAT cut is a waste of time are clearly not retailers, or resellers of services.
Yes, if you are a supplier showing the VAT on an invoice, I doubt it is doing you any good.
However, if you do NOT show VAT, you have been handed an extra 2.5% profit margin. As someone explained to me " It's all about being able to keep people in work."
Selling eg a ticket for a show at £65 is fine, reducing it to £63.61 will have no appreciable effect.
But if instead you stick to the £65 and keep the extra £1.39 and multiply that across a few thousand tickets, you are starting to make wages.
Which just might be the difference between survival and bankruptcy.
