Most MSME borrowers do not maintain P&L accounts, making income assessment for credit underwriting dependent on either costly CA estimates or inaccurate surrogate income proxies.
Business inflows from the bank statement (after personal transaction exclusion) are classified by channel and counterparty type to approximate revenue. Recurring and identifiable outflows are mapped to operating cost categories — cost of goods, staff, overheads, tax obligations, debt service — to produce a structured income and expenditure view.
Revenue classification rules vary by industry segment (trading: high-frequency moderate-value inflows; services: lower-frequency higher-value inflows; manufacturing: bulk NEFT/RTGS from distributors). Cost classification can be configured to exclude or include owner withdrawals from the operating cost total.
Synthetic P&L showing estimated gross revenue, estimated operating costs by category, estimated EBITDA proxy, and debt service coverage ratio (DSCR) derived from actual EMI outflows vs business inflow.
Approximately 90% of India’s registered MSMEs file no audited financial statements. For the lender trying to assess whether a trader in Surat or a fabricator in Ludhiana can service a ₹15 lakh working capital loan, the bank statement is the only structured financial record available. The question is not whether to use it — it is how to extract a credible income picture from it.
What a Synthetic P&L Is
A synthetic P&L is a structured approximation of a business’s revenue and operating cost position, constructed from categorised bank transaction data. It does not carry the assurance of an audit, and it does not produce balance sheet items or depreciation schedules. What it produces is a decisioning-grade view of cash-based income and expenditure — sufficient for loan sizing, DSCR calculation, and risk classification, but not for tax filing or investor disclosure.
The ICAI’s auditing standards draw a clear line around assurance engagements. A synthetic P&L sits entirely outside that boundary. Its value lies in its speed (minutes, not days), its cost (zero to the borrower), and its reproducibility (same inputs produce the same output, creating an auditable underwriting trail).
How Revenue Is Inferred
Business Inflow Classification
After personal transactions are excluded from the account, the remaining inflows are classified by channel. NEFT and RTGS credits from business-registered counterparties (identified through narration patterns, CIN references, and GST payer identifiers) are treated as B2B revenue. UPI credits from merchant-registered VPAs or known business counterparties are classified as business receipts. IMPS credits with trade-related narration markers follow the same logic.
The classification produces a business inflow ledger that approximates gross revenue. For a GST-registered MSME, GSTR-1 declarations serve as an independent cross-check on the revenue figure.
Recurring vs One-Time Inflows
Revenue inference distinguishes between recurring inflows (monthly patterns from the same counterparties — consistent with regular customers) and one-time large credits (advance payments, project receipts, asset disposal). Recurring inflows form the base for annualised revenue estimates. One-time credits are noted separately and excluded from trend-based forward projections unless the borrower provides context.
How Operating Costs Are Mapped
| Cost Category | Bank Statement Signal | Reliability |
|---|---|---|
| Cost of goods sold | Outflows to identified supplier/vendor accounts (NEFT, IMPS) | High — frequency and amount patterns consistent with procurement cycles |
| Staff costs | Recurring salary credits (NEFT to multiple individuals on consistent dates) | High — salary NEFT patterns are highly distinctive |
| Rent and fixed overheads | Recurring NACH debits or periodic NEFT to property-related accounts | Medium — hard to distinguish rent from equipment lease or insurance |
| GST / tax payments | Outflows to government accounts (GSTIN-linked banks, TDS challan payments) | High — tax payment narrations are structured |
| Loan repayments (existing) | NACH EMI debits, scheduled NEFT to NBFCs/banks | High — NACH mandate amounts are fixed and recurring |
| Owner withdrawals | Cash withdrawals, self-transfers to linked savings accounts | High volume but must be excluded from operating cost total |
What the Synthetic P&L Cannot Capture
Non-cash items are entirely absent: depreciation, amortisation, and provisions do not appear in bank statements because they involve no cash movement. Barter transactions, contra entries between related parties, and inventory adjustment entries are similarly invisible. Accrued income (invoiced but not yet collected) is excluded because it has not yet hit the bank account.
The synthetic P&L is, by nature, a cash-basis approximation. For working capital loan assessment — where the question is whether the borrower generates enough monthly cash flow to service an EMI — the cash basis is actually more directly useful than an accrual P&L. For term loan assessment requiring net worth and asset coverage, the synthetic balance sheet (a separate layer) is required in addition.
India-Specific Patterns That Affect P&L Construction
GST-filing-driven cash flow is a consistent feature of Indian MSME bank statements. GST liability payments (typically in the first week of the following month) create predictable outflow spikes that are operating costs, not revenue variances. Advance Tax payment dates (15 June, 15 September, 15 December, 15 March) create similar spikes. Systems that misread these large periodic outflows as operating cost increases will distort the month-over-month cost picture.
MSME Samadhaan (MCA’s MSME payment delay portal) data shows that payment delays of 45–90 days are common in B2B MSME transactions. This means revenue recognition in a bank-statement-based P&L lags actual invoicing by the same period — a point lenders need to account for when comparing the synthetic P&L against GST return data.
The bank statement analytics layer within TransactIQ constructs the synthetic P&L as part of the four-layer MSME synthetic financials output. The full methodology is described on the bank statement analysis platform page. The Institute of Chartered Accountants of India (ICAI) has published guidance on surrogate income documentation that provides useful context for where bank-based estimates sit relative to assurance standards.
