KASHFLOW One bill but 200 item how split/show in books

[the5ame]

We will have to register for VAT within next 2 month as coming to the treshold. When we become a VAT register how do we record purchases. Lets say I buy 200 different products from same company once a week. I pay all in one go (example £2400). Then company emails me an invoices for each item individually. How do I record this sale as on my Kashflow account as it apears as one payment. The £2400 includes VAT so will I have to pay minus VAT or same as before but show in books that this included VAT. Or I have to supply their company with my VAT number so they send invoices without and payment will exluded VAT?

Curently get invoice with this format:
PVC Book Shelf
Postage: 0.00
Price: £10.0
VAT: £2.00
Total: £12

CR Bank £12
DR Purchases £10
DR VAT £2

If you sell it for £24

DR Bank £24
CR Sales £20
CR Vat £4

If these were the only transactions in the VAT period, your profit will be £10 (£20 sales less £10 Purchase) and you will owe £2 VAT to HMRC (£4 - £2)
