I am trying to reconcile the difference between 2 tables using SQL Server 2005.
The tables are titled dbo.tblCustomersNew and dbo.tblProductsNew.

There is a 1 to many relationship between dbo.tblCustomersNew and dbo.tblProductsNew

Here is what I have found out so far:

select count(*) from dbo.tblProductsNew                   result set is 208565 records
----------------------------------------------------------------------------------------------------

SELECT Right(C.OfficeNumber,3) + ' ' + C.CustomerNumber AS [Account Number]
FROM dbo.tblCustomersNew AS C
INNER JOIN dbo.tblProductsNew AS P
ON   C.CustomerNumber = P.CustomerNumber
AND C.OfficeNumber      = P.OfficeNumber  
               
---------------------------------------------result set is 207206 records Matching records            
----------------------------------------------------------------------------------------------------

208565 minus 207206 = 1359 records difference
----------------------------------------------------------------------------------------------------
SELECT CustomerNumber, OfficeNumber FROM dbo.tblProductsNew
WHERE  CustomerNumber not in (SELECT C.CustomerNumber
FROM dbo.tblCustomersNew AS C
INNER JOIN dbo.tblProductsNew AS P
ON  C.CustomerNumber = P.CustomerNumber
AND C.OfficeNumber   = P.OfficeNumber)                    result set is 782 records

To find missing CustomersNew entries you need to use left join with a where clause, like this:
SELECT P.CustomerNumber, P.OfficeNumber
FROM dbo.tblProductsNew AS P
LEFT JOIN dbo.tblCustomersNew AS C
ON   C.CustomerNumber = P.CustomerNumber
AND C.OfficeNumber      = P.OfficeNumber
WHERE C.CustomerNumber IS NULL

To find missing ProductsNew entries use right join
SELECT Right(C.OfficeNumber,3) + ' ' + C.CustomerNumber AS [Account Number]
FROM dbo.tblProductsNew AS P
RIGHT JOIN dbo.tblCustomersNew AS C
ON   C.CustomerNumber = P.CustomerNumber
AND C.OfficeNumber      = P.OfficeNumber
WHERE P.CustomerNumber IS NULL
