VAT reporting on sales where we take deposits and balances

Hi- I am experiencing a problem and was helping someone could help point me in the right direct in regard to reporting on our VAT from shopify. We sell equipment and the VAT reports on this are straight forward. But we also sell experiences where the customer will visit our website and choose an experience and then pay a deposit, and then the balance maybe 6-7 months later. There is no transaction report for sales that I can see which will easily give me the data to ensure we only pay vat on the transactions we have recieved and not the total sales value of the order (where we have not recieved the balance yet). Does anyone else have this problem and if yes how do you get around it? I have spoken with shopify support and they have said even through the data is inside shopify there is no report that i can create which will give me the information

@JasonIngamells , Shopify, by default, calculates tax based on the total order amount rather than the transaction amount. To calculate tax on the paid amount, you need to create a sales level report, add the fields shown in the screenshot below, export the report, and compute it manually. If you want to avoid manual work, you can try Report Pundit, where tax is automatically calculated based on the transaction amount.
