The following is a condition that I need to implement

IF @CustomerId = '-1'
BEGIN
SET @whereClause = @whereClause
END
ELSE
BEGIN
SET @whereClause = @whereClause +' AND (Customer_id =' + '''' + @CustomerId + ''') '
END

Should I use a case statement here or leave it to IF ELSE... which will give me optimal performance?

IF @CustomerID <> '-1'
SET @whereClause = @whereClause +' AND (Customer_id = ' + '''' + @CustomerId + ''') '

will be enough
