Welcome to the QuickBooks family, mcpbuilders-sky-!
Do you want to use a specific code for your VAT? We have preset codes in QuickBooks, and some of them are used for reverse charges, RC. For example, the code 20.0% RC SG is for Standard reverse charge VAT for services.
Here's an article listing all the codes, their uses, and how they affect your VAT form: QuickBooks Online VAT codes. Basically, you'll assign the code to the applicable items on your invoice.
Feel free to go back to this thread if you have any other concerns. Take care!
