I'm nearly there, thank you! Just one more thing - when I try the final part of linking the Journal Entry on the pay bills page, it is asking that I put in the payment account at the top - is this simply the account that the refund was paid into? (current account)
Yes, ALKS. You've got it exactly right. The Payment Account should be your Current Account because that's where the refund from your supplier was deposited.
By selecting this account, you're connecting everything and letting QuickBooks know that the refund you received is being used to "pay off" the credit you recorded in the journal entry.
This final step clears everything out and correctly reflects that the supplier's bill has been settled.
Please don’t hesitate to leave a post below if you still need further assistance.
