Introduction
Over the past decade, India has emerged as a global fintech powerhouse, driven by innovations in digital payments. Among these, UPI AutoPay, eNACH, and digital challans are transforming how businesses manage recurring and statutory payments. These tools are no longer just conveniences they're becoming critical infrastructure for financial compliance, automation, and scale.
As business models shift across industries from SaaS to real estate to NBFCs businesses require payment systems to be automated, traceable, and regulation-proof. That's where such technologies come in. When implemented on enterprise-level platforms such as Castler, they provide unparalleled control and visibility over fund flows, whether you are collecting EMIs or paying taxes.
In this blog, we’ll explore each of these tools in depth, understand their specific use cases, and see how Castler leverages them to offer a unified, compliance-first platform for businesses operating in a fragmented financial landscape.
UPI AutoPay: From Instant Payments to Scheduled Success
What Is UPI AutoPay?
UPI AutoPay is an extension of the National Payments Corporation of India (NPCI)-launched Unified Payments Interface (UPI) that enables businesses to debit customers automatically at regular intervals after getting one-time approval. It can be imagined as the auto-debit facility of a credit card but much more affordable, flexible, and inclusive.
One-time UPI transfers do not facilitate:
Recurring payments for subscription-based services
EMI collections for NBFCs and lenders
Rental payments for property managers and landlords
Impact on Business of UPI AutoPay
For companies, the actual magic is predictability. With UPI AutoPay, companies do not have to chase customers for dues or send reminders every month. It delivers:
Increased collection rates on auto-deductions
Less operational overhead on manual reconciliations
Improved user experience, particularly for subscription businesses
Castler facilitates enterprise clients with UPI AutoPay using API integrations, enabling you to create, monitor, and manage recurring mandates with complete compliance and audit trails.
eNACH: A Pillar for Financial Institutions and Lenders
Understanding eNACH
eNACH is an electronic variant of the conventional NACH system as regulated by NPCI. It facilitates future-dated debits from customer bank accounts through a one-time e-mandate.
This facility is a lifeline for
NBFCs and banks receiving loan repayments
Subscription platforms receive recurring monthly or yearly fees
Companies handling bulk recurring payments
Why eNACH is a Must for Regulated Industries
For those running businesses in industries that have regulatory touch, eNACH is a non-negotiable option. It enables you to:
Keep complete KYC-compliant payment histories
Provide traceable and secure debit mandates
Work on multiple banks with high dependability
With Castler's Smart Pay-In suite, it is easy to integrate eNACH into payment processes. By combining this with digital identifiers unique IDs for each transaction or user you have real-time visibility and reconciliation abilities.
Digital Challans: Traceability for Statutory and Escrow Payments
What Are Digital Challans?
A digital challan is an electronic slip for making and tracking payments to statutory entities, regulators, or escrow accounts. These are typically utilized in:
Government and statutory payments
Regulator-imposed escrows
Tax settlements and penalties
Structured business payments, such as security deposits or property transactions
Every challan has a unique transaction reference number and has audit-ready traceability, making them the go-to for companies needing high compliance.
Use Cases Where Digital Challans Stand Out
Suppose you're a fintech platform that needs to pay into a regulatory escrow, like a co-lending platform or a digital asset exchange. A digital challan:
Makes funds traceable to origin
Streamlines audit processes
Reduces friction in high-value, high-risk transactions
Castler's platform facilitates digital challans as part of its end-to-end statutory payment and escrow infrastructure. From running a marketplace escrow to paying security deposits or statutory dues, Castler makes every challan mapped, reconciled, and compliant.
Why These Tools Matter More Than Ever
Business Payments Are Getting More Complex
Modern-day businesses don't just run on a monthly basis. They run on automated billing, multi-party settlements, and statutory payment mandates. Manual tracking, spreadsheets, and legacy banking portals are no longer sufficient.
Thanks to UPI AutoPay, eNACH, and digital challans, the Indian payments landscape is transforming into an automated, rules-based landscape at lightning speed—and businesses need to adjust to remain compliant and competitive.
Compliance and Automation Go Hand in Hand
All three of these tools enable not only operational productivity, but compliance in scale:
UPI AutoPay: RBI-supported and built with consumer approval
eNACH: Mandate-supported and audit-traceable
Digital Challans: Regulator-validated and secure
In regulated sectors, this is no longer a choice it's core.
