Hi, This is one of those reports I worked out by trial and error but I can tell you what I did and you can take that info away with you or work out a more simple way.

Unfortunately, there is no way to combine estimates and invoices into the same report (I've spent ages trying) so I have had to formulate two separate reports; one for estimates and one for invoices unpaid.

For invoices unpaid:

Clicked invoice list by date

Clicked customise tab

Made sure the transaction type had the invoice and payment selected

Then within that drop down menu within customise I selected A/R Paid and clicked the box Unpaid

That showed me a list of all of invoices that clients had not paid.

For the separate estimates report - under the filter tab- I just selected estimate status- accepted or pending.

Hope that helps.
