How are you manage when upload a receipt and have multiplies VAT breakdown , function Split its not work for me, show an error.

I can help you with adding and managing your receipts, Nicolae.

You can only split the amount in an uploaded receipt in QuickBooks Online (QBO). The option to break them down to multiple VAT is currently unavailable. 

Here's how:

1. Go to the Bookkeeping menu, select Transactions, and click on Receipts. 
2. Select Upload from computer and choose the receipt.
3. Click the Review button and then click on the + Add line to add the category and amounts.
4. Choose Save and Next or Save and Close once you're done. 

Refer to this article for more information about uploading your receipts and adding them to your account through the web or mobile device: Upload your receipts and bills to QuickBooks Online. 

From here, you can create and send customer statements in QuickBooks Online to show customers summaries of their invoices, payments, credits, and balances.

I'm always here to answer all the questions that you may have with your receipts. Keep safe, and have a wonderful day!
