Reconciling bank account is causing negative Accounts Receivable
We've invoiced customers and then subsequently marked those invoices as paid. Now I'm reconciling the bank account. I thought that I would be able to "match" the transaction from the banking screen. But no such luck, it's only showing invoices with open balances. If I add the transaction anyway, I'm either creating a negative A/R or I'll affect income. I don't understand why the deposit didn't take place when the invoice was marked as paid. How can I fix this?
