India’s microfinance sector serves <\/span>75 million borrowers<\/span><\/a> across 700 million in the eligible population. Gross loan portfolio crossed \u20b94 lakh crore in 2025.<\/span><\/p>\n

The sector has matured, NBFC-MFIs are regulated entities under RBI, the Credit Bureau links have eliminated the ghost borrower problem at scale, and digital collections have replaced physical cash handling for most urban MFIs.<\/span><\/p>\n

What has not changed: <\/b>the operational complexity of microfinance. Group lending requires tracking 20 borrowers in each group across weekly meeting cycles, calculating repayments that include principal, interest, and insurance premiums, managing collections from borrowers who have no smartphone and prefer cash, reporting to credit bureaus in real time, and satisfying RBI’s NBFC-MFI reporting requirements on a monthly basis.<\/span><\/p>\n

Building a microfinance platform that handles this complexity, for a group lender or an individual lending MFI, is a specialised engineering challenge. Generic NBFC software does not understand the group lending model. This guide covers how to build a platform that does.<\/span><\/p>\n

Module 1 – Branch, Centre, and Group Management<\/b><\/h2>\n

The microfinance geographic hierarchy:<\/b><\/p>\n

MFI (Head Office)<\/span><\/p>\n

\u2502<\/span><\/p>\n

\u251c\u2500 State \/ Zone<\/span><\/p>\n

\u2502\u00a0 \u2514\u2500 District<\/span><\/p>\n

\u2502 \u00a0 \u00a0 \u2514\u2500 Branch (physical office)<\/span><\/p>\n

\u2502\u00a0 \u00a0 \u00a0 \u00a0 \u2514\u2500 Centre (meeting location, school, community hall)<\/span><\/p>\n

\u2502 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u2514\u2500 Group (JLG, Joint Liability Group, 5\u201320 members)<\/span><\/p>\n

\u2502\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u2514\u2500 Member (individual borrower)<\/span><\/p>\n

 <\/p>\n

The centre meeting schedule:<\/b><\/p>\n

Every centre meets at a fixed time and location, every week or every fortnight, for <\/span>loan collection<\/span><\/a>, new loan disbursement, and group business. The platform manages the meeting schedule for every centre, generates the attendance register for the field officer, and tracks whether meetings happened as scheduled.<\/span><\/p>\n

Group formation rules (RBI NBFC-MFI guidelines):<\/b><\/p>\n\n\n\n\n\n\n\n\n
Rule<\/b><\/td>\nRequirement<\/b><\/td>\n<\/tr>\n
Group size<\/span><\/td>\nMinimum 5, maximum 20 members<\/span><\/td>\n<\/tr>\n
Member eligibility<\/span><\/td>\nAnnual household income \u2264 \u20b93 lakh (rural) or \u2264 \u20b93.6 lakh (urban\/semi-urban)<\/span><\/td>\n<\/tr>\n
Existing indebtedness<\/span><\/td>\nMember cannot have more than 2 MFI loans outstanding<\/span><\/td>\n<\/tr>\n
FOIR<\/span><\/td>\nFixed obligation to income ratio \u2264 50%<\/span><\/td>\n<\/tr>\n
Group guarantee<\/span><\/td>\nJLG, joint liability, all members guarantee each other<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The platform enforces these rules at the group formation stage, credit bureau checks run automatically, household income is captured in the appraisal form, and the FOIR is calculated before loan approval.<\/span><\/p>\n

\"\"<\/p>\n

Module 2 – Member KYC and Credit Appraisal<\/b><\/h2>\n

Digital KYC:<\/b><\/p>\n\n\n\n\n\n\n\n\n
Document<\/b><\/td>\nVerification<\/b><\/td>\n<\/tr>\n
Aadhaar<\/span><\/td>\nUIDAI OTP-based verification<\/span><\/td>\n<\/tr>\n
PAN<\/span><\/td>\nNSDL API verification<\/span><\/td>\n<\/tr>\n
Voter ID \/ Driving licence<\/span><\/td>\nDigilocker API<\/span><\/td>\n<\/tr>\n

Bank account<\/span><\/td>\nPenny drop verification<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Credit bureau integration:<\/b><\/p>\n

Before any loan is sanctioned, the platform mandatorily checks all four credit bureaus, CIBIL, Equifax, Experian, and CRIF High Mark, for the member’s credit history. The bureau check returns:<\/span><\/p>\n

Current active MFI loans (count and outstanding), RBI limits to 2 concurrent MFI loans. Total outstanding debt across all lenders. Overdue history and DPD (days past due) buckets. CIBIL MFI Score.<\/span><\/p>\n

The household income assessment:<\/b><\/p>\n

For low-income borrowers without formal income documentation, the field officer conducts a household income assessment, capturing income from all sources (agriculture, labour, business, remittances) and all fixed obligations (rent, existing EMIs, school fees). The platform calculates the FOIR and flags the application if it exceeds the RBI limit.<\/span><\/p>\n

\"\"<\/p>\n

Module 3 – Loan Origination and Disbursement<\/b><\/h2>\n

The loan product configuration:<\/b><\/p>\n\n\n\n\n\n\n\n\n\n\n
Parameter<\/b><\/td>\nDetails<\/b><\/td>\n<\/tr>\n
Loan amount<\/span><\/td>\n\u20b910,000 to \u20b91,50,000 (RBI NBFC-MFI limit)<\/span><\/td>\n<\/tr>\n
Tenure<\/span><\/td>\n12, 18, 24 months, weekly or monthly repayment<\/span><\/td>\n<\/tr>\n
Interest rate<\/span><\/td>\nRBI cap: lower of 22% per annum or cost of funds + 12%<\/span><\/td>\n<\/tr>\n
Processing fee<\/span><\/td>\nRBI cap: 1% of loan amount + GST<\/span><\/td>\n<\/tr>\n
Insurance premium<\/span><\/td>\nLife insurance mandatory, credit life, optional health<\/span><\/td>\n<\/tr>\n
Repayment frequency<\/span><\/td>\nWeekly (most common) or monthly<\/span><\/td>\n<\/tr>\n
Moratorium<\/span><\/td>\n0 or 1 repayment cycle moratorium after disbursement<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The EMI calculation:<\/b><\/p>\n

For a weekly repayment loan at 22% annual rate:<\/span><\/p>\n

Reducing balance EMI:<\/span><\/p>\n

Weekly interest rate = 22% \/ 52 = 0.4231%<\/span><\/p>\n

EMI = P \u00d7 r \u00d7 (1+r)^n \/ ((1+r)^n – 1)<\/span><\/p>\n

 <\/p>\n

For P = \u20b930,000, n = 52 weeks:<\/span><\/p>\n

EMI = \u20b930,000 \u00d7 0.004231 \u00d7 (1.004231)^52 \/ ((1.004231)^52 – 1)<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0= \u20b930,000 \u00d7 0.004231 \u00d7 1.2458 \/ 0.2458<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0= \u20b9644.78 per week<\/span><\/p>\n

 <\/p>\n

The platform calculates this precisely and generates the full amortisation schedule, showing the principal and interest component of every instalment, the outstanding balance after each payment, and the insurance premium collected each instalment.<\/span><\/p>\n

Disbursement methods:<\/b><\/p>\n\n\n\n\n\n\n\n
Method<\/b><\/td>\nUse Case<\/b><\/td>\n<\/tr>\n
Direct bank transfer (IMPS\/NEFT)<\/span><\/td>\nBorrowers with bank accounts<\/span><\/td>\n<\/tr>\n
Aadhaar-enabled Payment System (AePS)<\/span><\/td>\nBorrowers in areas with BC network<\/span><\/td>\n<\/tr>\n
Cash disbursement<\/span><\/td>\nRural areas without banking access<\/span><\/td>\n<\/tr>\n
Pre-paid card<\/span><\/td>\nAlternative for unbanked borrowers<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Module 4 – Field Collection App<\/b><\/h2>\n

The field collection app is the most critical module for daily operations. Field officers collect repayments from 200 to 400 members per day across 15 to 20 centre meetings. The app must work offline, rural connectivity is unreliable, and must be fast enough to process an entire centre meeting of 20 members in under 15 minutes.<\/span><\/p>\n

The collection workflow:<\/b><\/p>\n\n\n\n\n\n\n\n\n\n
Step<\/b><\/td>\nAction<\/b><\/td>\nTime<\/b><\/td>\n<\/tr>\n
Centre meeting start<\/span><\/td>\nField officer marks meeting started, GPS-verified<\/span><\/td>\n1 minute<\/span><\/td>\n<\/tr>\n
Attendance<\/span><\/td>\nMark each member present or absent<\/span><\/td>\n2 minutes for 20 members<\/span><\/td>\n<\/tr>\n
Collections<\/span><\/td>\nFor each member, enter amount collected<\/span><\/td>\n30 seconds per member<\/span><\/td>\n<\/tr>\n
Exceptions<\/span><\/td>\nRecord prepayments, part-payments, skips<\/span><\/td>\nAs needed<\/span><\/td>\n<\/tr>\n
Meeting close<\/span><\/td>\nSummarise total collected, print\/share receipt<\/span><\/td>\n2 minutes<\/span><\/td>\n<\/tr>\n
Sync<\/span><\/td>\nUpload all transactions when connectivity available<\/span><\/td>\nBackground<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Cash denomination tracking:<\/b><\/p>\n

For centres where cash collection is mandatory, the app includes denomination tracking, the field officer enters the denomination mix of the collected cash. This enables vault management at the branch, counting the day’s collection and matching it against the app’s total without manual reconciliation.<\/span><\/p>\n

Pre-payment and part-payment handling:<\/b><\/p>\n

Members sometimes pay more than their due instalment (pre-payment) or less (part-payment). The platform handles both:<\/span><\/p>\n

Pre-payment:<\/b> Excess applied to reduce the principal outstanding, shortening the loan tenure. <\/span>Part-payment: <\/b>Shortfall recorded as overdue, triggers reminder and escalation if not cleared by next meeting.<\/span><\/p>\n

\"\"<\/p>\n

Module 5 – Delinquency Management<\/b><\/h2>\n

The PAR (Portfolio at Risk) framework:<\/b><\/p>\n\n\n\n\n\n\n\n\n
Bucket<\/b><\/td>\nDefinition<\/b><\/td>\nAction<\/b><\/td>\n<\/tr>\n
PAR 0<\/span><\/td>\nCurrent, no overdue<\/span><\/td>\nNone<\/span><\/td>\n<\/tr>\n
PAR 1\u201330<\/span><\/td>\n1 to 30 days overdue<\/span><\/td>\nField officer contact, group pressure<\/span><\/td>\n<\/tr>\n
PAR 31\u201360<\/span><\/td>\n31 to 60 days overdue<\/span><\/td>\nBranch manager visit, recovery plan<\/span><\/td>\n<\/tr>\n
PAR 61\u201390<\/span><\/td>\n61 to 90 days overdue<\/span><\/td>\nSenior management, group guarantee invocation<\/span><\/td>\n<\/tr>\n
PAR 90+<\/span><\/td>\n90+ days overdue<\/span><\/td>\nNPA classification, legal, write-off consideration<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The escalation engine:<\/b><\/p>\n

When a member misses a payment, the escalation engine:<\/span><\/p>\n

Day 1 after due: Field officer receives an alert, member missed payment. Day 3: Branch manager notified if not resolved. Day 7: Area manager alert, group guarantee discussion initiated. Day 30: Credit bureau reported as overdue (SMA-1 classification). Day 60: NPA classification triggered if not resolved.<\/span><\/p>\n

The group guarantee mechanism:<\/b><\/p>\n

In JLG lending, all members of the group are jointly liable. When one member defaults, the platform activates the group guarantee workflow, the field officer facilitates a group meeting where members collectively decide how to handle the defaulting member’s obligation. This social pressure mechanism is the primary credit risk management tool in JLG microfinance.<\/span><\/p>\n

Module 6 – RBI Regulatory Reporting<\/b><\/h2>\n

NBFC-MFI returns (NBS-7):<\/b><\/p>\n

The platform generates the monthly NBS-7 return, the primary regulatory filing for NBFC-MFIs, automatically from operational data:<\/span><\/p>\n\n\n\n\n\n\n\n\n\n
NBS-7 Component<\/b><\/td>\nData Source<\/b><\/td>\n<\/tr>\n

Capital adequacy<\/span><\/td>\nCapital structure + risk-weighted assets<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

CRILC reporting:<\/b><\/p>\n

The Credit Repository of Information on Large Credits (CRILC) requires reporting of all borrowers with exposure above \u20b95 crore, typically not relevant for individual MFI borrowers but relevant for the MFI’s own borrowings. The platform generates CRILC data in the required format.<\/span><\/p>\n

Credit bureau reporting (real-time):<\/b><\/p>\n

Every loan disbursement, repayment, and delinquency event is reported to CIBIL, Equifax, Experian, and CRIF High Mark in real time through their respective APIs. This real-time bureau reporting is the foundation of the sector’s ghost borrower prevention mechanism.<\/span><\/p>\n

FAQs about Microfinance Software Development<\/b><\/h2>\n
    \n
  • \n

    What is a Joint Liability Group (JLG) in microfinance and how does a platform model it?<\/b><\/h3>\n<\/li>\n<\/ul>\n

    A Joint Liability Group (JLG) is a group of 5 to 20 individuals, typically women in India’s NBFC-MFI sector, who take individual loans but provide mutual guarantee for each other’s repayment. If one member defaults, the group is responsible for covering the shortfall before the MFI takes recovery action. The JLG model eliminates the need for collateral, the social collateral of the group replaces physical assets as the credit guarantee. A microfinance platform models JLG by maintaining a group entity that links individual member records, tracks the group’s aggregate delinquency, enforces RBI rules on maximum concurrent loans per member and income eligibility, and manages the group guarantee workflow when a member defaults.<\/span><\/p>\n

      \n

      What are the RBI NBFC-MFI loan limits and how does a platform enforce them?<\/b><\/h3>\n<\/li>\n<\/ul>\n

      RBI regulations (2022 Master Direction) set the following limits for NBFC-MFIs: maximum annual household income of the borrower, \u20b93 lakh for rural areas and \u20b93.6 lakh for urban\/semi-urban; maximum outstanding loan across all MFIs cannot exceed \u20b92 lakh at any point; maximum 2 NBFC-MFIs can lend to the same borrower simultaneously; fixed obligation to income ratio (FOIR), total loan repayments of the household cannot exceed 50% of household income; and maximum loan size is \u20b91.5 lakh for the first cycle, increasing in subsequent cycles. A microfinance platform enforces these limits at the loan appraisal stage, running mandatory credit bureau checks for current outstanding, calculating FOIR from the household income assessment, and blocking the loan sanction automatically if any limit is exceeded.<\/span><\/p>\n

        How does offline capability work in a field collection app for rural microfinance?<\/b><\/h3>\n<\/li>\n<\/ul>\n

        A field collection app for rural microfinance must function offline because most meeting locations, village schools, community halls, fields, have no reliable cellular data. The offline capability works as follows: at the start of each day, the app syncs the full data set for the field officer’s centres, member details, outstanding instalments due, payment history, and centre meeting schedules, to local device storage. During the day’s operations, all transactions are written to local storage. When the field officer returns to an area with connectivity, the branch, a town, or a highway, the app syncs all the day’s transactions to the central server automatically. The server validates the transactions against the master data and flags any discrepancies for manual review. The critical design requirement is that the field officer cannot tell the difference between online and offline mode, the app behaves identically in both states.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
