Hi @JackieOBrien
I think you need to add a bit of detail/background - what you're doing & why.
In pure accounting terms, every debit needs a credit to balance against. You can't add funds from fresh air - hence the Additional Credit when you add via Receive Payment.
If the money is being transferred from one business account to another then the credit/debit is obvious.
If the money is coming from outside the business, there needs to be an invoice or liability - such as a loan - to balance the credit.
Hope this helps.
