Q: What are the possible reasons for imbalances in these accounts?
Remember that the entries in the control accounts are general entries of totals from the subsidiary ledgers. So any error in "posting" these totals could cause an imbalance.
Likewise, entries in the individual accounts come from the individual entries in the subsidiary journals. So any error in "posting" the individual journal entries to these individual accounts could also cause an imbalance.
I know that is not very specific, but I hope that gives you a better idea of what could have caused an imbalance. If not, pop me another question with more details.
A: Well, an invoice here indicates that a sale was made. And a sale means debit the debtor (and credit the income).
If this transaction was not recorded, it means the debit to debtors was not recorded. So now you need to record it. So you enter a debit now on reconciliation. Hope that makes sense!
