STATUTORY OVERVIEW

Revenue Assurance, Operational Process Auditing & Leakage Control

In high-transaction and contract-driven commercial environments, unbilled service milestones, system calculation anomalies, expired promotional pricing, unauthorized credit notes, and delayed billing cycles result in substantial silent revenue leakages. A Revenue and Process Audit systematically evaluates the entire Order-to-Cash (O2C) continuum—from customer master setup, contractual rate cards, and delivery milestone validations to invoice dispatch, collection reconciliations, and credit management. Our Chartered Accountants evaluate your operational cycles to identify control weaknesses, recover unbilled income, and ensure revenue accounting conforms to Ind AS 115 / AS 9 and fiscal Income Computation and Disclosure Standards (ICDS IV).

Contract Compliance, Rate Card Audits & Billing Verification

Practice Scope & Statutory Guidance

We audit client master agreements, rate card schedules, contractual escalation clauses, milestone completion signoffs, and discount schemes against ERP and billing system configurations. Our procedures identify discrepancies such as delivered but unbilled deliverables, unauthorized commercial concessions, unbilled reimbursable expenses, and unindexed rate escalations, enabling immediate recovery of legitimate earned revenue.

Revenue Recognition Under Ind AS 115 / AS 9 & Fiscal ICDS IV

Practice Scope & Statutory Guidance

We evaluate corporate revenue accounting policies against the five-step model mandated under Ind AS 115 (Revenue from Contracts with Customers): (1) identifying the contract; (2) identifying distinct performance obligations; (3) determining the transaction price; (4) allocating transaction price to obligations; and (5) recognizing revenue as obligations are satisfied over time or at a point in time. In parallel, our audit cross-verifies revenue with Income Computation and Disclosure Standard IV (ICDS IV - Revenue Recognition) under direct tax law and reconciles turnover with GST electronic invoices issued under Rule 48(4) of the CGST Rules.

Process Control Optimization & Accounts Receivable Assurance

Practice Scope & Statutory Guidance

Our process audit analyzes billing turnaround times, credit limit enforcement, unadjusted advance payments, dispute resolution efficiency, and the adequacy of Expected Credit Loss (ECL) provisioning on aging trade receivables under Ind AS 109. By streamlining credit approval workflows and eliminating invoicing bottlenecks, we assist management in accelerating operating cash flows and reducing working capital cycles.

FREQUENTLY ASKED QUESTIONS

Statutory FAQs & Practical Guidance

Frequently asked questions and procedural guidance regarding Revenue & Process Audit.

What are the most common sources of revenue leakage in growing enterprises?

Revenue leakages most frequently stem from: (1) delivered services or dispatched goods where the billing team was not notified (unbilled milestones), (2) manual discounts entered without required managerial authorizations, (3) failure to invoice contractual inflation escalations or annual rate hikes, (4) unbilled out-of-pocket reimbursable expenses, and (5) system configuration mismatches between CRM pricing and ERP billing modules.

How does Ind AS 115 affect revenue recognition for bundled product-and-service contracts?

Under Ind AS 115, when a contract bundles goods and services (e.g., software license + implementation + annual maintenance), the transaction price must be allocated to each distinct performance obligation based on their relative standalone selling prices (SSP). Revenue must be recognized separately as each obligation is satisfied, preventing premature revenue recognition at contract signing.

What is the statutory timeline for issuing a GST tax invoice for services?

Under Section 31(2) of the CGST Act read with Rule 47, a tax invoice for the supply of services must be issued within 30 days from the date of the supply of service (or 45 days in the case of banking companies and financial institutions). Failing to issue the invoice within 30 days triggers interest liabilities under Section 50 and penalties under Section 122.

How does a Revenue Audit improve operating cash flows?

A revenue audit directly accelerates cash collections by: (1) identifying and liquidating unbilled work-in-progress into immediate invoices, (2) resolving long-pending customer invoice disputes through evidentiary documentation, (3) tightening credit limit enforcement to prevent sales to chronic defaulters, and (4) automating billing triggers upon milestone achievement.
