Recurring payments are essential for industries like lending, insurance, mutual funds, and subscriptions. However, manual collections and fragmented debit systems often lead to delays, mistakes, and high operational costs. This is why eNACH (Electronic National Automated Clearing House) has become the standard for automated recurring payments in India, and why Castler’s eNACH solution is seen as one of the most effective and compliant platforms for enterprise-level automation.

Automating collections isn’t merely about convenience; it’s also about control, predictability, and compliance. Businesses today seek systems that are not just fast but also secure, scalable, and approved by regulators. Castler’s eNACH solution meets these needs perfectly.

Let's break down how it works, its key features, industries that benefit most, and why it is becoming the preferred option for digital collections across various sectors.

What Is eNACH and Why Does It Matter?

The Electronic National Automated Clearing House (eNACH), developed by the National Payments Corporation of India (NPCI), is a centralized electronic mandate system. It allows businesses to collect recurring payments directly from a customer’s bank account once the customer provides digital authorization.

In simple terms, eNACH replaces paper mandates with a fully digital process. It enables organizations to automatically collect EMIs, premiums, subscriptions, or fees on set dates without manual involvement.

This model ensures payments are timely, reduces human error, and provides both customers and businesses with full visibility into fund transactions.

What truly distinguishes eNACH is that it has backing from regulators (RBI and NPCI), is designed to manage both small and large transactions, and seamlessly integrates with modern banking platforms like Castler Connected Banking.

Understanding Castler’s eNACH Solution

Castler’s eNACH platform simplifies and automates digital collections for enterprises and financial institutions. It connects directly with banking systems and APIs to manage the entire process from mandate registration to fund settlement in a fully digital, compliant, and real-time environment.

The platform allows businesses to quickly create e-mandates, collect payments automatically, monitor transactions live, and reconcile easily through a single dashboard. Whether you’re handling a few hundred mandates or scaling to millions, Castler’s infrastructure can manage it all effortlessly.

Let's explore the features that make it unique.

Key Features of Castler’s eNACH Solution

1. Fast and Secure Mandate Creation

Setting up an e-mandate with Castler takes only 24 to 48 hours. Businesses can create and send e-mandate links for digital authorization through net banking or debit cards. Once approved, the mandate is active, allowing automatic debits based on the defined schedule.

The authorization process is encrypted and meets NPCI standards, ensuring full security of customer credentials and data.

2. Flexible Frequencies and Amounts

Every business has its own collection patterns, whether it’s daily EMIs, monthly subscriptions, quarterly fees, or annual renewals. Castler’s eNACH solution supports custom debit frequencies and variable amounts, providing flexibility for different use cases. From fixed rent payments to usage-based SaaS fees, the system can be tailored to fit your business model.

3. Multi-Mode Authorization: Debit Card and Net Banking

Customers can authorize auto-debits using their preferred payment method, whether net banking or debit card. This flexibility improves adoption rates and guarantees a smoother customer experience.

4. High Transaction Limits for Enterprises

Castler supports high-value transactions of up to ₹1 crore per mandate, making it suitable for large enterprises, NBFCs, and B2B businesses that deal with high-ticket payments.

5. Seamless Auto-Debits for Every Use Case

Once a mandate is active, the system automatically debits the customer’s account according to the agreed frequency. This feature works well for EMIs, subscriptions, insurance premiums, SIPs, and fee-based services, ensuring payments occur on time, every time.

6. Integration with All Major Banks

A major advantage of Castler’s eNACH platform is its compatibility with banks across India. It integrates with all leading banks, ensuring high success rates for mandate creation and transaction processing. This prevents failed auto-debits due to limited bank coverage, a common issue in traditional systems.

7. Real-Time Alerts and Webhooks

The system is designed for transparency. Businesses receive real-time notifications on every key event, whether it’s mandate registration, debit success, failure, or settlement.

Using webhooks, this information can sync automatically with internal CRMs or ERPs, keeping all systems updated without manual input.

8. Payment and Settlement Reports

Castler’s dashboard offers detailed payment and settlement reports for easy reconciliation. Finance teams can track transactions, spot failures, and download reports instantly, all in one place.

9. Developer-Friendly APIs

Integration is simple. Castler provides modern, developer-friendly APIs and webhooks that work easily with existing CRMs, ERPs, or Loan Management Systems (LMS). Businesses can embed eNACH capabilities directly into their workflows without needing to rebuild current systems.

Industries That Benefit Most from eNACH Solution

While eNACH can apply to nearly all recurring payment scenarios, certain industries gain particularly high benefits from its automation and compliance advantages.

NBFCs and Digital Lenders

Loan recovery and EMI collections can be complex. eNACH automates recurring collections, which lowers delinquencies and removes the need for manual follow-ups. With automated EMIs, lenders can maintain steady cash flows and accurate reconciliation.

Insurance Companies

Timely premium collection is crucial for insurers to manage risk and ensure coverage continuity. eNACH enables customers to authorize premium auto-debits easily, preventing missed payments and improving policy retention rates.

Mutual Fund and SIP Platforms

For asset managers and SIP platforms, consistent investment cycles are essential. eNACH ensures that SIPs are debited on time, providing customers with a smooth investment experience and promoting continuous growth of assets under management.

EdTech Platforms

As education financing increases, eNACH simplifies installment payments for courses. Students or parents can authorize one-time e-mandates and pay automatically over time, improving affordability and reducing dropout rates.

SaaS and Subscription Providers

Recurring software and service fees often rely on card billing. eNACH offers additional reliability, especially for large B2B subscriptions or for customers who prefer direct bank payments.

Rental and Leasing Services

From real estate to co-working spaces and equipment rentals, eNACH helps automate rent collection. This approach ensures predictable cash inflows and significantly reduces collection costs.

These use cases show a clear trend: any business that relies on recurring, predictable payments stands to benefit from eNACH automation.
