1. Set up an Owner's Draw equity account, if you don't have one. Go to Settings > Chart of Accounts > New, choose Equity as the account type, and Owner's Draw (or Partner's Draw for multiple owners) as the detail type.
2. Figure out how the money actually left the business. A check written directly to the owner, a bank transfer to a personal account, or a straight cash withdrawal all count, they just get entered slightly differently.
3. Record it as a check or expense, not an invoice or bill. This isn't a vendor transaction, so use + New > Check or + New > Expense, pick the bank account the money left from, and code the whole amount to the Owner's Draw equity account.
4. For a cash withdrawal with no check written, use an Expense entry. Same equity account, dated to match when the cash actually left the business, even without a physical check to point to.
5. Leave net income and Retained Earnings alone. A draw doesn't touch the profit and loss statement at all. At year end, QuickBooks still rolls net income into Retained Earnings the normal way; the draw just sits in its own equity account alongside it for your accountant to review.
