How does one enter a starting balance for Accounts Receivable? How do you enter transactions into Accounts Receivable if you don't want a AR Subledger? Thank you!

We can add an opening balance by creating a Journal Entry, userdziegenf.

Let me guide you with these steps:

1. From the + New button, select Journal entry.
2. Select Opening Balance Equity in the first ACCOUNT column.
3. Enter the amount on the CREDITS field.
4. Select accounts receivable account on the second line.
5. Enter the same amount under the DEBITS column.
6. Select a customer's NAME.
7. Click  Save and close.

With regard to recording a transaction on the account's receivable account, QuickBooks doesn't user A/R Sub-Ledger. All transactions default to a single A/R Accounts. That explains why it needs a customer name to identify where and to whom the balance is.
