you could take what theSQLGuru wrote and make it generalizable for all years with Datepart functions.
select sum(case when datepart(mm,Invoice_date)=1 then Total_Amount else 0 end ) as Jan,
sum(case when datepart(mm,Invoice_date)=2 then Total_Amount else 0 end ) as Feb,
-- etc
Datepart(yy, Invoice_date) as Yr
from #RECEIVABLE
group by Datepart(yy, Invoice_date)
