ORDER BY
CU.CompanyName, ISS.InvoiceDate
How can I group this to SUM ISS.InvoiceTotal grouped by CustomerKey?
I keep getting the "is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause." error.
Any ideas?

If you SUM() in the ISS table you can't select from it or add it to the GROUP BY.
SELECT
[CustomerKey] AS 'Cust #',
CU.[CompanyName] AS 'Company Name',
LAST(ISS.InvoiceDate) AS 'Invoice Date',
SUM(ISS.InvoiceTotal) AS 'Invoice Total',
ISNULL(CU.ShopPhone,'') AS 'Company Shop',
ISNULL(CU.CellPhone,'') AS 'Company Cell',
ISNULL(CU.OfficePhone,'') AS 'Company Office',
ISNULL(CF.FirstName, '') AS 'FName',
ISNULL(CF.LastName,'') AS 'LName',
ISNULL(CF.WorkPhone,'') AS 'Contact Work',
ISNULL(CF.CellPhone,'') AS 'Contact Cell',
ISNULL(CF.HomePhone,'') AS 'Contact Home',
ISNULL(CF.EMail,'') AS 'Contact Email',
PSO.OutsidePartsSalespersonName
