Supplementary Bill
A Supplementary Bill is an additional bill issued to a member outside the regular monthly billing cycle, typically to charge for arrears, interest on late payment, a special levy, or a one-time charge.
What is Supplementary Bill?
When a society needs to bill a member for something not covered in the regular monthly bill — back-billing for missed charges, interest on overdue amounts, a special assessment, or a one-time repair levy — a Supplementary Bill is raised separately.
Supplementary Bills carry their own bill number and due date, and appear in the member's ledger as a distinct entry from regular monthly bills.
Why it matters
Mixing supplementary charges into regular bills creates confusion and audit complications. A separate Supplementary Bill keeps the member ledger clean and makes it easy to track which charges relate to which obligation.
For interest on arrears, a Supplementary Bill provides the legal basis for recovery and is required before initiating recovery proceedings under the MCS Act.
Legal & regulatory context
Special levies approved by the General Body must be billed and collected separately — not bundled into maintenance. A Supplementary Bill is the correct instrument.
Supplementary Bills for interest must specify the principal amount, period, and rate of interest. This is required for the bill to be enforceable in recovery proceedings.
How SocietyBee handles it
SocietyBee supports Supplementary Bills as a separate bill type. The treasurer selects the member, enters the charge head, amount, and due date. The system auto-posts to the member ledger and links back to the original arrear or charge that prompted the bill.

Can a supplementary bill include multiple charge heads?
Yes. A single supplementary bill can include interest, a special levy, and arrears from a prior month — each as a separate line item with its own amount.
Is a General Body resolution required before issuing a supplementary bill for a special levy?
Yes. A special levy must be approved by the General Body before bills are issued. Supplementary bills for interest on arrears do not require a GB resolution if the interest rate is already in the bye-laws.
