- In the Payments to Deposit window, click OK.
- In the Make Deposits window, enter where you want to deposit the money in the Deposit To field.
- Enter the Date and Memo.
- In the Received From column, select the customer.
- Check the deposit total. Make sure the account and selected payments match the deposit slip from your bank. Use your deposit slip as a reference.
- Click Save & Close.
