FinTech solutions — payments, reconciliation and dashboards
What We Do

Payment systems that balance to the paisa

Most fintech projects fail after the demo — at reconciliation, certification and audit time. We build for those days first: every transaction traceable, every exception surfaced, every regulated step handled by a licensed partner.

Read this first: Addroit Nexus is a technology partner — not a bank, PSP, payment aggregator or NBFC. We never hold settlement funds or float. Every regulated rail (payments, AEPS, BBPS, KYC, lending) runs through licensed partners; we design, integrate and operate the software around those rails.

From tap to bank credit, one traceable line

A customer pays by UPI at your counter or checkout; that rupee then crosses a gateway, a nodal account, a settlement file and your ledger. We build the software that follows it the whole way — checkout and mandate journeys on the front, webhooks, retries and T+1 reconciliation files on the back — so your accounts team sees one clean, matched line.

Built for Bharat-scale operations

Our fintech work leans towards the India that pays in UPI and cash-out at agent counters: kirana-friendly retailer apps, Hindi-first screens, collections apps that print receipts in the field, and dashboards a promoter can read on a phone. Metro-grade engineering, Tier-2 empathy — designed and supported from Lucknow.

FinTech Offerings

Six things we build exceptionally well

UPI & payment-gateway integrations

Checkout, UPI intent and collect, autopay mandates, payment links and dynamic QR — wired to the aggregator or bank PG whose rates and success curves fit your volumes.

Payout & refund automation

Vendor, agent and customer refunds through partner payout APIs — approval queues, automatic retries on failure, and a state machine that never loses a rupee in limbo.

Reconciliation engines & MIS

Three-way matching across PG ↔ bank ↔ ledger with T+1 exception reports, ageing views and drill-downs — MIS your CA and your auditor will both sign off on.

Agent-network stacks

AEPS, micro-ATM and BBPS retailer apps built on licensed API providers — agent onboarding, commission ledgers, float top-ups and settlement views for networks of thousands.

NBFC & co-operative tooling

LOS/LMS-lite for small lenders and co-ops: EMI schedules, field collections app with instant receipts, bucket-wise overdue views and head-office reporting.

KYC & onboarding flows

Aadhaar-based, CKYC and DigiLocker journeys through licensed KYC providers — consent capture, graceful retries and audit-ready logs on every verification.

The Reconciliation Story

Close the day in minutes, not weekends

Reconciliation is where fintech operations quietly bleed hours. A purpose-built engine turns it from a weekly Excel marathon into a T+1 exception queue.

Hours per week spent reconciling payments

Indicative, for a business doing roughly 5,000 transactions a month across two gateways and a bank account.

Dashboards & MIS for founders, ops and auditors

One screen for the promoter (collections, success rate, settlement due), one for operations (exception queue, refund ageing, agent float) and one for the auditor (immutable logs, maker-checker history, downloadable registers). Same data, three honest views — refreshed as settlements land.

Compliance-Aware Engineering

Built as if the auditor is already in the room

We are engineers, not compliance officers — your partners and advisors own the legal view. But we build so that their job is easy: data kept in India-region infrastructure in line with RBI data-localisation expectations, PCI-DSS-aligned practices with no raw card storage (cards stay tokenised at the gateway), and controls that assume every action will one day be questioned.

That mindset costs little on day one and saves the project when a partner audit, investor due diligence or a disputed transaction lands on your desk.

The default control set

  • India-region hosting aligned with RBI data-localisation direction for payment data
  • No raw card numbers stored, ever — tokenisation stays with the licensed gateway
  • Maker-checker approvals on payouts, refunds and master-data changes
  • Append-only audit trails: actor, timestamp, before and after values
  • Role-based access, IP allow-listing and full session logs on back-office tools
  • Encryption in transit and at rest; secrets in vaults, never in code
  • DPDP-aware consent capture and data-retention schedules
FAQ

FinTech questions, answered straight

Is Addroit Nexus RBI-licensed? Are you a bank, PSP or NBFC?
No — and we say this plainly. Addroit Nexus is a technology company. Payments, settlement, AEPS, BBPS, KYC and lending all run through licensed banks, payment aggregators and API providers; you (or we, on your behalf) contract with them for the regulated service, and with us for the software, integration and operations around it.
Which payment gateways and providers do you integrate?
The major Indian aggregators (Razorpay, PayU, Cashfree and peers), bank-provided gateways, and specialist licensed API providers for AEPS, micro-ATM, BBPS and KYC/CKYC/DigiLocker journeys. We are not tied to any one — we shortlist by success rates for your payment mix, pricing, settlement terms and sandbox quality, and we put the comparison in writing.
How long does a UPI integration take?
A hosted-checkout UPI integration is typically live in 2–3 weeks. Deeper builds — autopay mandates, custom flows, agent-network features — usually run 6–10 weeks because partner sandbox access and certification queues sit on the critical path. We publish a week-by-week plan at kickoff, with partner dependencies marked honestly.
Do you handle settlement money or float?
Never. Customer funds move through the licensed partner nodal, escrow or settlement accounts as their licence requires; agent float sits with the licensed provider. We build the software that initiates, tracks, reconciles and reports — the money itself never touches an Addroit account.
How do you keep payment data secure?
No raw card storage (PCI-DSS-aligned by design — tokenisation stays with the gateway), TLS everywhere, encryption at rest, vault-managed secrets, maker-checker on sensitive actions, append-only audit trails and India-region hosting. Access to production data is role-based, logged and reviewed — and we will happily walk your auditor through all of it.
People Also Ask

FinTech Solutions — 20 questions, answered straight

The most-asked questions on the web about this topic, answered honestly by our team.

What is fintech in simple words?
Fintech is technology applied to money — payments, lending, insurance, investments and accounting delivered through apps and APIs instead of branch counters. UPI, payment gateways, khata apps, online insurance and robo-advisors are all fintech. For a business, fintech in practice means collecting money digitally, reconciling it automatically, and plugging financial services into your own software instead of sending customers somewhere else to pay you.
What is a payment gateway and how does it work?
A payment gateway is the service that moves money from your customer to your bank account when they pay on your website or app. It presents payment options (UPI, cards, net banking, wallets), talks securely to banks and card networks, confirms success or failure to your software, and settles collected amounts to your account after its cycle. In India, gateways operate under the RBI payment-aggregator framework.
What are typical payment gateway charges in India?
Published rates commonly sit near 2% plus GST for cards and wallets, 1–2% for net banking, and zero for UPI on most plans under current MDR policy — though gateways may charge platform fees on some UPI flows. Watch the fine print: setup fees, minimum commitments, international card rates (3% and up), and refund fees. Negotiate once you cross a few lakh rupees of monthly volume.
Is UPI really free for merchants?
For person-to-merchant UPI, MDR is currently zero by government policy, so most merchants pay nothing per transaction on standard UPI. Nuances exist: wallet-based UPI above certain amounts carries interchange, some providers charge for value-added flows like AutoPay or one-click checkout, and the zero-MDR policy is debated every budget season. Enjoy it while it lasts, and re-check the rules once a year.
Can a business accept digital payments without a website or app?
Easily. A static QR code on the counter takes UPI. Payment links sent on WhatsApp or SMS collect card and UPI payments with no code at all. A soundbox announces received payments so staff stop checking phones. Invoicing businesses can use hosted payment pages from any gateway. Websites and apps matter when you need payments reconciled automatically against orders — not for merely collecting money.
What is a payment link and when should I use one?
A payment link is a URL that opens a ready payment page for a specific amount — send it on WhatsApp, SMS or email and the customer pays by UPI or card without visiting any website. It is ideal for advances, service invoices, distance sales and customers who will not install anything. Links can carry expiry dates, partial-payment rules and automatic receipts, and settle like any gateway payment.
What is a soundbox and is it worth the rent?
A soundbox is the small speaker that announces each received UPI payment aloud — solving the real problems of fake payment screenshots and staff checking phones mid-rush. Providers charge roughly ₹100–150 per month as rental. It is worth it for busy counters handling many small payments; unnecessary where payments are few and a screen is visible. Some billing systems offer app-based audio confirmation as a free alternative.
What is BBPS (Bharat BillPay)?
BBPS — the Bharat Bill Payment System — is the NPCI-run network behind bill payments: electricity, gas, water, DTH, FASTag, insurance premiums, loan EMIs and more. Apps and agents fetch bills and accept payments through one standard rail with instant confirmation. For retailers, becoming a BBPS agent through an aggregator adds a commission-earning counter service; for billers, joining BBPS places your bills inside every major payment app.
What is UPI AutoPay and how do subscriptions collect automatically?
UPI AutoPay creates an e-mandate: the customer approves once, and recurring charges up to the mandated amount debit automatically on schedule — used for OTT, SIPs, EMIs and software fees. Above RBI-set limits, individual debits need re-authentication. For businesses, AutoPay sharply cuts failed collections versus manual reminders; you integrate it through your payment aggregator. Always provide an easy cancellation path — it is mandatory, and it builds trust.
Why do payment companies ask for so many KYC documents?
RBI obliges them to know exactly who receives money through their rails — to fight fraud, money laundering and terror financing. Expect to provide PAN, business proof (GST, Udyam or registration), bank proof and the owner ID. Mismatched names across PAN, bank account and business records are the top onboarding delay, so fix those first. Tightening rules on personal QRs used for business are part of the same push.
When does money actually reach my account (what is a settlement cycle)?
Gateways settle in cycles: T+1 (next working day) is now standard in India, with same-day or instant settlement offered for a fee by many providers. The clock starts when a transaction completes, and bank holidays pause it. Plan working capital around it — a Saturday sale on T+1 may credit on Monday. Reconcile settlements against orders, because refunds, chargebacks and fees are netted inside each payout.
What is reconciliation and why does it matter?
Reconciliation is matching three records — what your system says was sold, what the gateway says was collected, and what the bank statement shows credited. Mismatches happen daily: dropped webhooks, refunds, double payments and fee deductions. Unreconciled books mean silent leakage and GST filings that do not tie out. Automate it beyond a few dozen transactions a day; a finance person burning evenings on Excel matching is the classic symptom.
What happens in a UPI dispute or chargeback?
The customer raises a dispute with their bank or app; it travels through NPCI rails to your gateway, which asks you for proof of service or delivery within a deadline. Respond with invoices, delivery proof or usage logs — silence usually means an automatic debit of the disputed amount. Card chargebacks work similarly under card-network rules. Keep evidence organised; dispute win rates track documentation quality almost perfectly.
What is a virtual account and why do businesses use them?
A virtual account is a unique account number or UPI ID generated per customer or invoice that routes into your main account. Because each payer has their own number, incoming NEFT, IMPS and UPI credits identify themselves — no more guessing which customer paid ₹18,500 yesterday. They are widely used for B2B collections, fees, rentals and dealer networks. Ask your bank or aggregator for smart-collect or virtual-account APIs.
Do I need an RBI licence to add payments to my app?
Usually no. If you collect through a licensed payment aggregator, the licence burden sits with them and you sign up as a merchant. Your own authorisation becomes necessary when you start handling other people's funds — operating as an aggregator, wallet or third-party payout provider. That line is easy to cross accidentally (a marketplace settling money to sellers, for instance), so take advice before routing anyone else's money through your books.
Is it legal to launch a lending or pay-later app in India?
Only regulated lenders can lend: banks and registered NBFCs. An app without an NBFC licence must partner with one, and the RBI Digital Lending Guidelines govern the whole arrangement — funds must flow directly between lender and borrower, key-fact statements are mandatory, and data collection is restricted. Illegal loan apps face crackdowns and app-store delistings. If you build in this space, budget for compliance first and features second.
What is card tokenisation and why can apps no longer store card numbers?
RBI barred merchants and gateways from storing real card numbers; instead, card networks issue a token — a stand-in number valid only for that merchant. Customers keep the saved-card convenience, while a database leak yields useless tokens. If you build commerce software, integrate token flows through your gateway rather than ever touching card data — that choice also keeps most of the PCI DSS compliance burden off your stack.
What is the Account Aggregator framework?
Account Aggregators are RBI-licensed consent managers: with the customer's explicit digital approval, they fetch financial data — bank statements, deposits, GST returns, insurance — from institutions that hold it and pass it, encrypted, to institutions that need it, typically for loan underwriting. No consent, no data; every consent is purpose-bound and time-bound. For lenders and fintechs, AA replaces PDF statements and screen-scraping with clean, verifiable data rails.
How much does it cost to integrate a payment gateway into a custom app or website?
The gateway itself is usually free to integrate — its costs are per transaction. Development effort is the real line item: a solid integration with order tracking, webhooks, refunds and reconciliation typically takes days to a few weeks of engineering. Indicatively, Addroit Nexus quotes such integrations from about ₹15,000–50,000 depending on platform and flows (indicative, GST extra), including sandbox testing and go-live support.
How does GST e-invoicing connect to payment systems?
Businesses above the e-invoicing turnover threshold (₹5 crore at present) must register B2B invoices on the government IRP, which returns an IRN and QR code. Well-built systems generate the invoice, register it and attach a payment link in one flow — so the same record drives GST returns, receivables and reconciliation. Even below the threshold, structuring invoices this way makes eventual compliance a switch-flip rather than a rebuild.
