Sole Trader accounting for used van purchase

Can anyone help me please? How do I account for this situation in a sole trader accounts for the tax year 2022/2023? Purchase of used van 02.08.2023 for £12,995 +VAT £2,599= Total £15,594 Part exchange given for traded-in van £800 How do I put this in our accounts which are done on traditional not cash basis. We are VAT registered. Thank you.

Hi,
You can see guidance here:

Thank you.

Thank you. I have read that and remain confused. Do I just add total of £15,594 into account software as a bill allocated to "Motor Vehicle Purchase" and if so should that be for the total amount of £15,594?

Thank you.

So no help at all then. I am more than capable of finding links to guidance and reading content. HMRC sets the rules; I just want to ensure that I apply them correctly but seemingly, HMRC isn't interested. So I will just hazard a guess. Don't think I will bother using this supposed "help" again!
