You need not look any further, @user08758. I'm here to help you prepare your estimates right away.
To clarify, do you need to pull up a report with the previous month's estimates? You can utilize the Estimates by Customer report. It shows a list of estimates for each customer. Additionally, this report shows the status of your estimates if it has been applied to an invoice.
