1.7 Invoice discounting and receivables finance

Invoice discounting finances an SME’s receivable — the SME’s customer owes it money, and the NBFC advances cash against that receivable. Repayment happens when the customer pays. Tenure is typically 30 – 90 days.

This is conceptually close to supply-chain finance but without a formal anchor programme — the invoice is the credit unit, not the borrower relationship.

Three structural variants

Variant	Where it sits	Regulator
TReDS-based	On a regulated exchange (RXIL, Invoicemart, M1xchange)	RBI-regulated TReDS framework, auctioned to multiple financiers
Factoring (assigned)	Outright purchase of the receivable by the NBFC	RBI Master Direction – Regulatory Framework for Non-Bank Factors, post Factoring Regulation (Amendment) Act 2021
Secured lending against receivables	Loan, with the receivable as collateral / repayment source	Standard NBFC lending; no factoring registration required

The 2021 amendment to the Factoring Regulation Act materially broadened who can do factoring — pre-amendment, only specialised factoring NBFCs could; now, any NBFC can do factoring up to specified limits. Open-market invoice discounting platforms have grown rapidly post-2022.

Money flow (TReDS-based)

1. Seller MSME uploads invoice on a TReDS exchange.
2. Buyer (corporate / PSU) confirms the invoice on the exchange.
3. Multiple financiers (banks, NBFCs, factoring companies) bid to discount the invoice; lowest bid wins (auction).
4. Winning financier pays seller upfront (invoice value minus discount).
5. On the original due date, buyer pays the TReDS exchange, which routes to the financier.
6. Settlement is T+1 or T+2 typically.

TReDS reduces credit risk to the buyer’s risk (since the invoice is confirmed) and standardises the operational rail. The trade-off is that pricing is auctioned and very competitive — yields are lower than open-market invoice discounting.

Risk owner

• TReDS: financier (buyer-anchored risk).
• Factoring (assigned): NBFC outright.
• Secured lending: NBFC, with receivable as recovery source.

Borrower / customer relationship

In open-market invoice discounting the SME’s customer (the buyer) may not even know the receivable has been financed. Some structures notify the buyer (notification factoring); others don’t (non-notification). Notification factoring is operationally safer (NBFC can collect directly from buyer) but commercially harder (buyers may resist).

Underwriting owner

NBFC. Underwriting in invoice discounting splits into two:

1. Borrower underwriting — the seller SME’s overall creditworthiness, GST, bank, bureau, Tally.
2. Invoice / buyer underwriting — each invoice’s authenticity (GST e-invoice cross-check, e-way bill where applicable) and the buyer’s credit quality (separate bureau pull on the buyer entity).

Collections owner

NBFC. Mechanism depends on structure:

• TReDS: exchange handles settlement.
• Notification factoring: NBFC collects directly from buyer on the due date.
• Non-notification / secured: seller receives buyer’s payment and is contractually obliged to remit to NBFC, with NACH backstop.

Fees and pricing

• Discount rate / yield: 10% – 16% annualised (lower for TReDS, higher for open-market non-notification).
• Processing fee: minimal — sometimes a flat ₹ per invoice or none on TReDS.
• Platform fee: TReDS exchanges charge a small per-invoice fee.

Regulatory risks

• Factoring vs lending re-characterisation — must structure cleanly as one or the other; the regulator looks at substance.
• e-invoice fraud — duplicate invoices, fake invoices, invoices already discounted elsewhere. Mitigated by mandatory cross-check with GST e-invoice portal (IRN-based) for invoices above the e-invoice threshold (currently ₹5 Cr aggregate turnover, periodically lowered).
• Notification mechanics under the Factoring Act — formal assignment must be notified to the buyer in specified form.

Technology modules needed

• Standard origination + LMS modules.
• Invoice intake module — bulk upload (Excel, GSTR-1 import), e-invoice IRN lookup, validation.
• Buyer master + buyer-credit module — independent credit assessment of each buyer.
• Per-invoice ledger with disbursement, expected collection date, actual collection.
• TReDS connector if participating.
• GST e-invoice integration for IRN validation.

Integrations needed

• GST e-invoice portal (einvoice1.gst.gov.in, einvoice2.gst.gov.in, etc.) — IRN validation.
• TReDS exchanges (RXIL, Invoicemart, M1xchange) — financier API onboarding.
• NACH for seller backstop mandate.
• Bank payout for advance, bank receipt for collection.
• Standard NBFC integrations (bureau, KYC, etc.).

Unit economics

For a ₹30 Cr open-market invoice discounting book, 45 days average tenure:

Line	Annualised
Yield	13% – 16%
Origination fee	1% – 2% annualised (low; invoices are commoditised)
Cost of funds	11% – 13%
Operating cost	1% – 2%
Credit cost	0.5% – 2% (depends on buyer concentration and verification rigor)
Pre-tax ROA	1.5% – 3.5%

TReDS yields are tighter, often 8% – 11% net to financier. Pure TReDS is a volume play that requires scale to be meaningfully profitable.

Pros

• High capital turn (short tenure, repeat cycles).
• Cash-flow-backed underwriting.
• TReDS provides a regulated, transparent rail.
• Naturally PSL-eligible (small business buyers / sellers).

Cons

• Buyer concentration risk.
• Invoice fraud is the dominant credit risk; verification rigor is mandatory.
• TReDS is highly competitive and margin-thin.
• Open-market is operationally heavier and harder to scale without anchors.

Scalability

Moderate-to-high on TReDS (volume game). High on open-market with good buyer panels but operationally expensive.

Fit for SME working-capital ₹20–50 lakh, 60–180 days, repeat borrowers

Good fit, but not the primary wedge. Tickets in invoice discounting commonly land in ₹5 lakh – ₹50 lakh per invoice, and a borrower may discount several invoices per month, aggregating to the same effective lending volume as a working-capital line. The recommended approach:

1. Start with revolving working-capital lines for SME borrowers (covered separately).
2. Add invoice discounting as a top-up product for borrowers whose cash conversion cycle is fundamentally receivable-driven.
3. Layer TReDS participation by year 2 as a complementary low-credit-cost programme.
