Hi TeaKayB,
You’re on the right track following that advice. In your Crunch account, the invoice was raised in GBP. Even though payment was made in AU$, you’ll still record everything in GBP.
On your bank statement, you should see the amount from your client after it’s been converted to GBP. Record this as the payment against your invoice.
You’ll have an amount outstanding. Record another payment for this remaining amount, also in GBP. Then finally, record an expense in GBP for the same amount as the second client payment.
When you reconcile, you’ll match the first client payment against your bank statement. The second client payment and expense won’t need to be reconciled.
Hope this helps,
Katie
