Here's how advanced payment restrictions work for a specific income category. Let's look at different situations:
Scenario 1 (April 2023): A monthly invoice of Rs. 5000 is generated. If the user pays Rs. 60000 for the whole year, including April's invoice, the advance payment will cover the entire invoice because it's meant for maintenance costs.
Scenario 2 (May): An ad hoc invoice for parking charges of Rs. 1000 is issued on May 15th. The advance payment won't be used for this invoice, and it will remain as a payable amount.
Scenario 3 (July): The association decides to add GST to maintenance fees. The invoice is:
Maintenance Fee: Rs. 5000
CGST 9%: Rs. 450
SGST 9%: Rs. 450
--------------------------------------
Total Payable: Rs. 5900
In this case, the advance payment covers the entire invoice, including GST, as GST is applied to maintenance fees.
Scenario 4 (August): The association adds water charges to the monthly maintenance fee. The invoice looks like this:
Maintenance Fee: Rs. 5000
Water Charges: Rs. 500
CGST: Rs. 450
SGST: Rs. 450
------------------------------------------
Total Payable: Rs. 6400
The advance payment will be used for the entire invoice, including water charges and GST, as water charges are now part of the maintenance invoices.
