Allow me to assist you in handling this transaction receipt, Anthony.
In QuickBooks Online Sole Trader, only imported bank transactions can be split and linked to a single receipt. Since the purchase was made on your wife's card, I recommend manually recording an expense transaction to reflect the business-related portion.
For detailed steps, here's how:
- Navigate to Transactions from the left navigation bar.
- Click the New Transaction tab.
- Enter the Date and select Expense as the type.
- In the Payee field, enter the name of the vendor.
- Enter the business portion in the Amount and toggle it to Business Use.
- From the Category dropdown, select the appropriate business category.

Since we cannot directly link the transaction receipt to this expense transaction, I suggest adding a Note on it for proper documentation. Please note that contacting your professional accountant for guidance on the specific category to use is advisable.
Feel free to ask if you need clarification on these steps or help with any other tasks in QuickBooks Online Sole Trader.
