Want to see when orders come in, and when it's slow?
Create a custom report to see "Invoices by Date" in QuickBooks.
Start by selecting the following menu items:
Reports->Custom Reports->Transaction Detail Report
First thing go to Filters Tab.
Filter will be set at "All Accounts"
Change that to "All Ordinary Income Accounts"
Next go to Header/Footer Tab
Rename the header words from "Custom Transaction Detail Report" to "Invoices by Date" or some catchy report title.
You'll see your report of a list of Invoices. (And maybe some sales receipts and deposits depending on how you note sales).
Change your date range perhaps.
Fix the columns perhaps.
Memorize the Report.
Now you'll know the best time to take a vacation!
