How to get same result without using CROSS and ROWNUMBER

With Tb1 as
(select Date,Particulars,BillAmount,0'PaidAmount' from tblBill
union
select Date,Particulars,0'BillAmount',PaidAmount from tblPayment
)

SELECT T1.Particulars,T1.[Date],T1.[BillAmount],T1.[PaidAmount],(Sum(T2.BillAmount) - Sum(T2.PaidAmount)) as Balance FROM Tb1 as T1
            INNER JOIN
                Tb1 as T2
                ON T1.[date] >= T2.[date]
                Group By T1.Particulars,T1.[Date],T1.[BillAmount],T1.[PaidAmount]
                Order by [Date]
