How to Build a Digital Lending App as an RBI LSP (2026 Directions)
AI Summary: Building a digital lending app as an RBI Lending Service Provider (LSP) requires the right technology, a regulated lending partner, and strong compliance practices. This guide covers RBI digital lending directions, essential app features, lender integrations, security requirements, and development costs to help you plan and launch your lending platform in India. |
Most digital lending apps in India are not lenders. They are lending service providers (LSPs) that find, onboard and service borrowers for banks and NBFCs. Since May 2025, the rules for that model sit in one place: the Reserve Bank of India (Digital Lending) Directions, 2025.
Those Directions read like a product spec. They decide which phone permissions your app may ask for, what data you may keep, what the borrower must see before signing, how money moves, and how you must show offers when you work with more than one lender. This guide turns them into a build plan for founders and product teams.
For the wider licence picture across India, the US, the UK and the EU, see our Fintech Licensing Requirements 2026 guide.
Who is who: RE, LSP and DLA
The Directions use three terms you will see in every partner contract.
Term | Meaning under the Directions | Example in your product |
Regulated Entity (RE) | The bank, NBFC or other RBI-regulated lender that makes the loan | Your lending partner |
Lending Service Provider (LSP) | An agent of the RE that carries out one or more digital lending functions for it, such as customer acquisition, services incidental to underwriting and pricing, servicing, monitoring or recovery | Your company, if you run the app for lenders |
Digital Lending App/Platform (DLA) | A mobile or web app that facilitates digital lending services | Your borrower app and website |
The RE stays fully responsible for what its LSPs do. The Directions say outsourcing to an LSP does not dilute or remove the RE's obligations. In practice, your lending partner will check your technology, data handling and conduct closely before signing, and will keep reviewing you.
Your three routes
Route | What you are | What you need | Trade-off |
Own NBFC | A lender (RE) | An NBFC registration from RBI, capital and full prudential compliance | Full control and margin, but slow and capital-heavy |
LSP to one or more REs | Agent of the lenders | Contracts with each RE, their due diligence, and a DLA that meets the Directions | Fast to market; the lender owns the loan book and the risk |
Technology vendor | Software provider to an RE | A software contract; no customer-facing lending role | No borrower relationship, but no LSP duties either |
Most startups launch as an LSP. Some later add their own NBFC. If that is your plan, build the platform so the lender is a configuration, not hard-coded logic.
What the 2025 Directions require of the app
Data collection and phone permissions
The Directions require data collection to be need-based, with the borrower's prior and explicit consent and an audit trail. DLAs must not access files and media, contact lists, call logs or telephony functions. A one-time access to the camera, microphone, location or similar may be taken only for onboarding or KYC, with explicit consent.
Borrowers must be able to give or refuse consent for specific data uses, restrict sharing with third parties, revoke consent, and ask for their data to be deleted. Your consent manager is therefore a core module, not a checkbox screen.
Data storage
The RE must make sure LSPs do not store borrowers' personal information except basic minimal data (such as name, address and contact details) needed for their operations under the RE-LSP agreement. Clear policies on what is stored, for how long, how it is destroyed and how breaches are handled must be published on the website and in the app. Design your LSP data store to hold the minimum and keep the rest with the lender.
Key Fact Statement, APR and cooling-off
Before the borrower signs, the app must show a Key Fact Statement (KFS) in the standard format, with the all-inclusive cost as an Annual Percentage Rate (APR). The Directions also require a cooling-off period during which the borrower can exit by paying back the principal and the proportionate APR, without a penalty. The period must be at least one day, and the KFS must state it.
Build the KFS as generated output from the lender's pricing engine, not a static document, and store a copy with every loan.
Fund flows
Disbursements and repayments must move directly between the borrower's bank account and the RE's account. They must not pass through a pool account of the LSP or any third party. Your app shows and starts these flows, but the RE's accounts hold the money.
Multi-lender aggregation
If you work with several lenders, the Directions add rules that took effect on 1 November 2025. Your app must show all the loan offers that match the borrower's request from the lenders you work with, and identify the lenders that did not make an offer. Each offer must show the lender's name, loan amount, tenor, APR, monthly repayment, any penal charges and a link to the KFS. If you rank offers, the ranking must use a metric that you disclose, and the display must not push the borrower with dark patterns.
Grievances and disclosures
The app and website must show the RE and LSP details, a grievance redressal officer, and the complaint route. Every borrower communication must make clear which lender is behind the loan.
Reporting the app to RBI
REs must report every DLA they use, including those run by their LSPs, on RBI's Centralised Information Management System (CIMS) portal. RBI publishes a public list of these DLAs so borrowers can check whether an app really works with a regulated lender. Give your lending partners the data they need for that filing and keep it up to date.
Compliance-by-design checklist
Requirement | Feature to build |
Need-based data, explicit consent, audit trail | Consent manager with versioned consent records |
No access to contacts, files, call logs, telephony | Restricted Android/iOS permissions; automated permission checks in CI |
LSP stores only basic data | Split data stores; tokenised references to lender-held data |
KFS with APR before signing | KFS generator tied to the lender's pricing; e-sign flow |
Cooling-off exit | Prepayment flow during the cooling-off window, priced per the KFS |
Direct fund flows | Disbursement to borrower's account and collection into the RE's account (e-NACH/UPI AutoPay mandates) |
Multi-lender display | Offer comparison screen with all matching offers and non-matching lenders listed |
Grievance redressal | Complaint intake, tracking and escalation with SLAs |
CIMS reporting | DLA metadata export for each RE |
Reference architecture
A typical LSP platform has these layers:
Borrower apps: Android, iOS and web, with onboarding, offers, KFS, e-sign, repayments and support
Onboarding and KYC: Aadhaar-based eKYC or offline verification, PAN checks, video KYC where the RE requires it, and CKYC
Underwriting data: credit bureau pulls through the RE, bank-statement analysis, and Account Aggregator consent flows
Lender gateway: one integration layer for all REs, with each lender's products, rules and APIs mapped to a common model
Offer engine: collects and displays offers in line with the multi-lender rules
Loan servicing view: schedules, repayments, foreclosure and statements, read from the lender's LMS
Collections: reminders and recovery workflows that follow the RE's instructions
Compliance layer: consent records, audit logs, grievance management and DLA reporting data

Integrations and APIs
Lender APIs: loan application, decisioning, sanction, disbursement and repayment status from each RE
KYC: Aadhaar eKYC, PAN, CKYC, video KYC
Account Aggregator: consented bank-statement data through an AA such as Finvu
Credit bureaus: usually through the RE
Mandates: e-NACH and UPI AutoPay for repayments
e-Sign and e-Stamp for loan documents
Communications: SMS, email and WhatsApp with lender-branded templates

Common mistakes that delay lender go-live
Lenders run enhanced due diligence on every LSP before signing, and they keep reviewing you afterwards. These are the issues that most often hold up that review.
Over-broad app permissions. An Android build that still declares contacts or call-log permissions from an old SDK will fail review even if the code never uses them. Audit every third-party SDK in the app, not just your own code.
Personal data in the wrong place. Analytics tools, CRM systems and support desks often end up holding PAN numbers, bank statements or KYC images. Map every system that touches borrower data and cut it back to the basic minimum the Directions allow the LSP to keep.
Static KFS documents. A PDF template that does not match the lender's actual pricing creates mismatches between the KFS, the loan agreement and the repayment schedule. Generate the KFS from the same data that books the loan.
Hidden ranking logic. On multi-lender platforms, offer ranking that quietly favours the lender paying the highest commission is exactly what the Directions target. Disclose the metric and log every offer you showed.
No consent history. If a borrower revokes consent, you need to show when it was given, what it covered and when it stopped. Store consent as versioned events, not a single flag.
Lender logic hard-coded in the app. Each new lender then means a new app release. Keep lender products, eligibility rules and documents in configuration behind a lender gateway.
Collections without guardrails. If you act as a recovery agent for the RE, your reminders and calls must follow the lender's instructions and RBI's conduct rules. Build call-time limits, approved scripts and recording into the collections tool.
Fixing these before your first lender review usually saves weeks of back-and-forth.
Cost and timeline drivers
We do not publish fixed prices without a scope. These factors move the estimate most:
Number of lenders: each RE has its own APIs, products and due-diligence process
Products: personal loans, BNPL-style credit, business loans and gold loans need different journeys
Multi-lender display: the comparison flow and its documentation add design and testing work
KYC depth: video KYC and offline verification add vendors and edge cases
Security and audits: your lenders will ask for security testing and policy evidence before go-live

1. What is a Lending Service Provider (LSP) in digital lending?
An LSP is a company that works with a regulated lender, such as a bank or NBFC, to provide digital lending services like loan applications, customer onboarding, and borrower support.
2. Do I need RBI approval to start an LSP business in India?
An LSP generally does not need a separate RBI licence just for its LSP role. However, it must partner with an RBI-regulated lender and follow applicable digital lending requirements.
3. What features should a digital lending app include?
Key features include digital KYC, loan applications, credit assessment support, loan offers, e-signatures, repayment tracking, grievance support, and secure document management.
4. How much does it cost to build a digital lending app in India?
The cost depends on app complexity, lender integrations, security, and compliance workflows. A basic lending app costs less than a platform with automated underwriting and advanced analytics.
5. What are the key RBI compliance requirements for an LSP?
LSPs must follow applicable RBI digital lending rules, including transparent loan disclosures, Key Fact Statements, direct fund flows between borrower and lender, data privacy, and grievance redressal requirements. The regulated lender remains responsible for its LSP's activities.
