One product, three jobs
The arithmetic behind a UK VAT return, worked from your own figures: any receipt or invoice split into net and VAT at 20%, 5% or zero, the box of the return each total lands in, the £90,000 rolling-twelve-month registration threshold, and the free Making Tax Digital software compared on the one thing that decides it.

Built for UK VAT only
The sole trader, one-person company or small business doing its own VAT return, and nobody else
Type the number on the receipt, say whether it already includes VAT and at which rate, and get the split back. The VAT on a £120.00 standard-rated receipt is £20.00, and the tool shows why it is one sixth of the total rather than a fifth of it.
Sales and purchases sorted into the boxes the return asks for: the net of a purchase into box 7 and its VAT into box 4, the net of a sale into box 6 and its VAT into box 1, so the return is a total rather than a guess.
Every quarter saved with the figures behind each box, the rolling twelve-month taxable turnover tracked against the £90,000 threshold, and the digital records Making Tax Digital asks for, ready to hand to whoever submits the return.

Vatnix: The product itself, next to the free calculator that does it

A general ledger prices for the whole of a business's books and asks you to run the whole of them. Most of a small trader's VAT trouble is one question: which figure goes in which box, at which rate: and that is what this does.: Submits, and prices for the whole ledger to do it
