Record dropshipping

I have LTD (VAT) and sometimes I sell goods of my partner (sole trader VAT) on my website. She pays all shipping. I recorded payment as payment from customer but now I need invoice from my partner.
The customer is from Australia so I shouldn’t pay VAT. She did not pay vat for shipping to Australia as well.
How should look our invoices?
Regards

This is more of an accountant question rather than a QuickFile one - it’ll depend on exactly who is the customer to whom, it may be that if you (ltd) are selling to your partner (sole) and then they are selling on to the Australian customer then you would have to charge VAT to your partner and then they invoice the customer without VAT as an “out of scope” export sale. Ask your accountant.
