1.1. When I had setup the business, I had used my personal bank account to fund the businsss and therefore transferred amount to business bank account. I used the the journal entry to map it to retained earnings/equity.
1.2.Should I have used the expense claim?
1.3. Also, when the business is gaining its profits, how should I return the money back to my personal bank account in case if I have used retained earnings/equity
1.4. What is the best way to reflect my entire fundings in the past as liabilities. Should I put all financial funds as expense claims till date and modify the retained earning/equity journal entries?
That was incorrect. You should have used a receipt, posted an equity account suitable for your type of business organization, such as a capital account or owner’s equity account. When you started the business, you had no retained earnings. And because you used a journal entry, no cash or bank account was debited with your contribution of funds.
You should enter a payment to yourself, posting the payment to an appropriate equity account. Again, the type of equity account depends on the legal structure of your business.
Why do you want to do this? It is doubtful everything you have contributed to funding of the business is a liability. Based on your questions, you seem to need the advice of an accountant. These are not really questions about Manager.
