How do I enter historical transactions without affecting the current balances?
I am trying to figure out how I can add income/expenses to my client's books without affecting the B/S and I/S as they stand. My problem is, once I've entered the B/S balances, anytime I add a journal entry for an income(donation)/expense item, it changes the final balances. I want to be able to add all income/expense accounts without affecting the balance sheet balances.
Background: I recently inherited a religious organization's accounting and I have a Balance sheet and an Income Statement but I don't have many of the transactions because they were using an outdated system form the 90s and their past accountant left the church. I have the B/S and I/S up to 9/30/2018 so I want to enter all of the information in and continue from there.
