Let me help and share with you some information concerning splitting an invoice between different parties.
I could definitely see how you would want to split an invoice for different parties. Right now, we don’t have a splitting feature for invoices in QuickBooks Online, so it has to be done manually. For the meantime, you can create an invoice for each party.
I’ll speak with our engineering team about the splitting feature and will let you know whenever we have it available for our users. Additionally, I'd encourage you to visit our QuickBooks Blog, so you'll be updated with our latest news and updates including product improvements. Just go to https://quickbooks.intuit.com/uk/blog/.
