We'll have to set up an equity account, thesalonhampshir.

I've got the steps on how to do it:

First, we'll have to set up an owner as a supplier. This helps us track what you or the co-owners contribute to your business. I'll show you how:

1. From the Expenses tab, select Suppliers.
2. Click New Supplier.
3. Enter their information, and then click Save.

Afterward, let's set up an equity account:

1. From the Accounting tab, select Chart of Accounts.
2. Click New.
3. From the Account Type, select Equity.
4. Select Owner's Equity or Partner's Equity depending on your situation.
5. Click Save.

Once done, you can now record the investment. If you've connected your bank into QuickBooks, you don't need to record the investment. You'll just have to categorize them.

If you've manually imported the transactions, we'll have to record a deposit into your equity account.

1. From the + New button, select Bank deposit.
2. From the Account drop-down, select the bank account you're depositing the money into.
3. Enter the Date.
4. In the Add funds to this deposit section, enter the name of the investor in the Received from field.
5. Select an Account.
6. Specify a Payment method.
7. Enter the investment amount in the Amount field.
8. Select Save and close.

When you're ready to pay it back, you can check this article for the steps to record it. Record paying back an investment.
