An unpaid supplier does not automatically become entitled to start insolvency proceedings merely because an invoice is overdue. Under the Insolvency and Bankruptcy Code, 2016, an operational creditor must first understand whether the claim is an operational debt, whether a default has occurred, whether there is a genuine pre-existing dispute, and whether the statutory demand-notice process has been followed before a section 9 application is considered.
The procedural framework is set out in the Insolvency and Bankruptcy (Application to Adjudicating Authority) Rules, 2016, available through IBBI's official rules repository. For accountants and credit-control teams, the most useful distinction is between the section 8 demand stage and the later section 9 application stage.
Who is an operational creditor?
Operational debt generally arises from claims connected with the provision of goods or services, including employment-related claims, and certain statutory dues within the Code's definition. A person to whom such operational debt is owed can fall within the operational-creditor framework. The classification matters because financial creditors and operational creditors use different initiation routes under the Code.
For a trade supplier, the accounting label “trade receivable” is therefore only the starting point. The underlying transaction, debtor identity, due date, evidence of supply and any dispute should be examined before an insolvency route is treated as available.
Step 1: establish the debt and default
Before issuing an insolvency demand notice, the creditor should build a clean evidence file. This normally includes the contract or purchase order, invoices, delivery or service-acceptance evidence, ledger, correspondence, payment history and a calculation showing the amount claimed and when it became due.
This exercise is important because the statutory forms require particulars of the transaction and debt. A section 9 application is not meant to replace ordinary bookkeeping or reconstruct a vague claim after the event.
Step 2: choose the correct section 8 demand route
Rule 5 of the Application to Adjudicating Authority Rules provides the operational-creditor demand mechanism. The demand notice may be delivered in Form 3, or a copy of an invoice attached with a notice in Form 4, as applicable to the nature of the claim. The official rules contain both prescribed forms and their required particulars.
The choice should not be treated as cosmetic. If the debt arises through invoices, the invoice-based route and supporting records should be reviewed carefully. Where the claim is not represented by an invoice in the same way, Form 3 provides the prescribed demand-notice structure. The notice should accurately identify the debt, default and supporting transaction rather than merely demand a round figure.
Step 3: serve the notice properly
The rules prescribe modes for delivering the demand notice or invoice notice to the corporate debtor. Creditors should preserve evidence of service because service is part of the statutory sequence leading to a section 9 application.
A practical file should retain the signed notice, annexures, dispatch or electronic-service evidence, delivery confirmation and the corporate debtor's response, if any. Credit teams should not rely only on an email sitting in an employee's mailbox without preserving the complete service record.
What happens during the 10-day response period?
Section 8 gives the corporate debtor an opportunity to respond after receipt of the demand notice. The debtor may bring to the operational creditor's notice the existence of a dispute or relevant proceedings, or provide evidence of payment. The section 9 route is considered only after the statutory response period has run its course and the conditions for filing are otherwise satisfied.
This is one reason insolvency should not be treated as a routine debt-collection threat. If a genuine dispute already existed before the demand notice, that fact can be fundamental to whether the operational creditor can use the insolvency process.
Pre-existing dispute: why the timeline matters
Suppose a vendor supplied software implementation services and raised an invoice for ₹20 lakh. Two months before any insolvency notice, the customer had repeatedly alleged in writing that key deliverables were incomplete and had withheld acceptance. The vendor cannot safely analyse the case by looking only at the unpaid invoice. The earlier correspondence may evidence a dispute that existed before the section 8 notice.
By contrast, a bare denial invented only after receipt of the demand notice is a different factual situation. The creditor's lawyer will need to assess the actual record, but the finance team's contribution is to preserve the chronology rather than selectively collect only documents favourable to recovery.
Step 4: section 9 application and Form 5
Where the statutory conditions are met after the demand stage, an operational creditor may apply to the Adjudicating Authority under section 9. The Application to Adjudicating Authority Rules prescribe Form 5 for the operational creditor's application to initiate corporate insolvency resolution process.
The official Form 5 requires detailed particulars and supporting material. Its instructions include the demand notice or invoice notice served on the corporate debtor, documents relied upon to prove the operational debt and default, an affidavit, proof of the prescribed application fee, and proof of serving copies as required. The form also provides for information concerning a proposed interim resolution professional where applicable.
Information Utility record: a useful evidence layer
IBBI's official circular repository includes its 20 June 2023 circular concerning section 7 or section 9 applications accompanied by a record of default issued by an Information Utility. For creditors that have an authenticated or otherwise usable Information Utility record, this can form an important evidence layer alongside contracts, invoices, bank records and correspondence.
It should not encourage weak underlying records, however. The operational creditor should still be able to explain the transaction, due date, amount in default and dispute history coherently.
Practical example: undisputed supply invoice
Assume a company supplied industrial components to a corporate customer. The customer accepted delivery, recorded no quality objection, made part-payment and then stopped paying the balance. The supplier's ledger, purchase order, invoices, delivery records, bank statement and correspondence all reconcile. In such a case, the credit team can give counsel a structured file for assessing the section 8 demand process and, if statutory conditions remain satisfied after the response period, a possible section 9 application.
The point is not that every unpaid invoice should enter insolvency. The point is that a clean, undisputed operational debt is very different from a claim whose amount, performance or contractual entitlement was already contested.
Operational-creditor documentation checklist
- Identify the legal debtor: verify the exact corporate debtor name, registered office and corporate records instead of relying on a trade name.
- Reconcile the debt: agree invoices, credit notes, receipts, part-payments and ledger balance.
- Prove supply or service: retain purchase orders, agreements, delivery challans, acceptance records, timesheets or other transaction evidence.
- Establish the due date and default: document contractual payment terms and the calculation of the amount claimed.
- Review the dispute chronology: collect complaints, debit notes, rejection emails, arbitration or suit records and other pre-notice correspondence.
- Use the prescribed demand form: prepare Form 3 or the invoice-linked Form 4 route as applicable and ensure annexures are complete.
- Preserve service evidence: keep proof showing when and how the corporate debtor received the notice.
- Prepare the section 9 file only after the demand stage: if the statutory conditions are met, reconcile Form 5 and its annexures before filing.
Common mistakes to avoid
- Using IBC as the first collection email: insolvency initiation has statutory prerequisites and should not be reduced to a generic payment threat.
- Ignoring an earlier dispute: finance teams should disclose the complete correspondence history to counsel.
- Serving an informal demand instead of the prescribed process: the section 8 notice stage and applicable forms matter.
- Claiming an unreconciled balance: old credit notes, part-payments or ledger mismatches can undermine the credibility of the debt calculation.
- Failing to preserve proof of service: the filing file should show compliance with the statutory sequence.
- Assuming section 9 filing guarantees admission: the Adjudicating Authority examines the statutory requirements and facts; filing is not the same as admission of CIRP.
Practical takeaway
For an operational creditor, the IBC route is a structured insolvency process, not a substitute for ordinary recovery follow-up. Start by proving the operational debt and default, review whether a genuine dispute pre-dated the notice, use the prescribed section 8 demand mechanism, preserve service and response evidence, and only then assess a section 9 Form 5 application with professional advice. A disciplined accounting and document trail is often the most valuable preparation finance teams can provide.
