if vat is 8164 then your van’s net cost should be 40,820 that means you have 345 worth of exp at zero vat? plz double-check your van price based on I guess Hire purchase.
You need to book an invoice for the van at the original net price + vat, any associated admin charges also become part of the van cost. Then record 18164 as bank payment and allocate it to this van invoice. Then create a bank account on QF in name of the lease company and record a transaction of the original gross van cost less 18164 and tag that to van invoice, this should leave the invoice as fully paid and the new lease company a/c as liability, moving on from next month payments from main bank a/c to lease company, just tag it to new lease company bank a/c as an interbank transfer.
This should put vat in your vat return now and give you the correct HP liability outstanding every month
