VAT is the first tax that punishes bad timing. Register late and HMRC backdates your liability to the day you crossed the threshold — you owe VAT on sales where you never charged it. Register too early while selling to consumers and you've just made yourself 20% more expensive than the competition. Neither mistake is difficult to avoid; both are expensive to unpick.
So we treat VAT as a decision first and an admin job second: work out the right registration date for your customer mix, pick the scheme that suits your cashflow, then run the quarterly cycle so it never lands on your desk again.
