Backdating a receipt to keep it in 2024, when the transaction occurred

Yes, @galvanicmac.

I'll share insights about how entering dates in transactions works in QuickBooks Online (QBO).

You can date the receipts for the payments received in late December with the actual transaction dates, even if you're sending the receipts in early January. This approach ensures that your financial records accurately reflect when the payments were received, which is particularly important for year-end financial reporting and tax purposes.
