How do I split my expenses so when I scan a receipt, I can put them into fuel, equipment, food etc to make my accounts more straight forward

I'll shed some more light on how receipts and expenses work in QuickBooks. 

The option to split your expenses when scanning a receipt is unavailable. However, we can review, edit, add, or match them with existing transactions to ensure it is categorised and accounted for properly. Then, add lines to split and categorised them. See the see screenshot for your reference: 

Here's how to upload a receipt and review it in QuickBooks then add it directly to your books: 

1. Go to Transactions, then select Receipts (Take me there).
2. In the For review tab, review your uploaded receipts and bills. QuickBooks lets you know if it finds existing transactions in your books that match with your uploaded receipts or bills.
3. Check the labels in the Action column to find out what steps you need to take next.

However, you can use the Bank Rules module to automatically add those expenses (and other downloaded transactions) into QuickBooks. The receipts would still need to be reviewed and added though. To use the Split option in the Banking page, refer to the steps below:

1. Click the Banking menu and select the bank account where the transactions are allocated.
2. Next, look for the expense transaction and click to expand the view.
3. Select the Categorise radio button.
4. Then, click the Split option.
5. From there, select the appropriate information for each field.
6. Once done, click Apply and accept.
