India no longer treats digital payments as a trend. It treats them as plumbing. UPI alone now processes more than 20 billion transactions every month, and it accounts for well over three-quarters of all retail digital payment volume in the country. Wallets, tokenised cards, instalment credit, cross-border transfers and embedded checkout have followed, so almost every business that sells something is now asking how money should move through its own app.
Bangalore sits at the centre of that shift. The city has deep engineering talent, a long banking-technology heritage and a dense network of payment startups that keep raising the bar for speed and reliability. Founders looking for a build partner here face a crowded field, though, and most lists never explain who suits which kind of job.
This guide covers fifteen companies with genuine payment, banking or fintech engineering exposure. Each entry states where the company fits best and gives a short overview, so you can narrow your shortlist in a few minutes.
Why Bangalore Leads in Payment Engineering
Payment software is unforgiving. A checkout that fails at peak traffic costs money within seconds, and a security gap can cost a licence. Bangalore offers three things that reduce those risks: engineers who understand distributed systems, product teams that have already run at national transaction scale, and easy access to the technology arms of banks and fintech firms.
The numbers explain the demand. India has more than 700 million smartphone users, and digital payments there have been growing at double-digit rates year after year. Globally, annual digital payment value is already well past ten trillion dollars. Businesses that once treated an in-app payment flow as a nice extra now treat it as the core of the customer journey.
What to Check Before You Hire a Payment App Partner
A polished portfolio is not enough. Payment products carry regulatory and security obligations that ordinary apps never face, so ask pointed questions before signing anything.
Compliance knowledge: Does the team understand RBI guidelines, PCI DSS requirements, data-localisation rules and KYC norms?
Security practice: Look for encryption standards, tokenisation, penetration testing and a clear incident process.
Integration experience: Past work with UPI, card networks, payment gateways and banking APIs matters more than generic app credentials.
Scalability proof: Ask how a past product handled festival-season traffic or a sudden promotional spike.
Post-launch support: Payment systems need monitoring, patching and reconciliation help long after release.
On cost, rough market ranges put a basic wallet or UPI-style app at around ₹8 lakh to ₹15 lakh, while fuller products with lending, rewards or multi-bank support commonly run from ₹20 lakh to ₹50 lakh or more. Basic builds often take three to six months, and larger platforms can need nine to twelve.
The 15 Companies
1. Dev Technosys
Best for: Startups and mid-sized businesses that want a fully custom wallet, UPI or peer-to-peer payment app built end to end.
Overview: Dev Technosys is a mobile and web development company that has spent years building fintech products, including digital wallets, payment gateways, lending apps and money-transfer platforms. Its teams work across Android, iOS and cross-platform frameworks, and they usually handle design, development, testing and release support under one roof. Clients tend to value the flexible engagement models, from fixed-scope builds to dedicated teams. Encryption, tokenisation and compliance-minded architecture form part of its standard payment-project approach.
2. Infosys
Best for: Banks and large financial institutions modernising core payment systems at national scale.
Overview: Infosys, headquartered in Bangalore, is one of India's largest technology services firms, and its banking software sits inside many lenders' payment operations. The Finacle platform is widely used for core banking, digital channels and payment processing. The company brings deep experience in real-time payment rails, regulatory reporting and system migration, which makes it a natural fit when a project touches legacy infrastructure. Smaller product teams may find the engagement model heavier than they need, so it suits well-funded programmes more than lean launches. It also serves overseas banks.
3. Wipro
Best for: Enterprises that need payment modernisation tied to wider cloud, security and digital transformation programmes.
Overview: Wipro is a Bangalore-headquartered IT services major with a long record in banking, capital markets and insurance technology. Its payments work covers transaction platform upgrades, API-led integration, fraud analytics and cloud migration for financial clients across several continents. The firm is strongest where payments form one piece of a larger transformation, since it can bundle infrastructure, cybersecurity and application engineering. Early-stage founders building a single app may find its scale more than necessary, while corporate buyers often value the breadth and process maturity.
4. Mphasis
Best for: Card, lending and payment-processing programmes at banks that want an experienced engineering and operations partner.
Overview: Mphasis is a Bangalore-based services company with a large share of its revenue coming from banking and financial services. It has worked on card-processing systems, digital onboarding, loan origination and payment operations for global lenders. The company combines engineering with business-process capabilities, so it can support both the software and the day-to-day handling around it. Its focus on applied technology and automation also appeals to institutions trying to cut manual reconciliation. It is typically engaged for sizeable, multi-year initiatives rather than quick prototypes.
5. LTIMindtree
Best for: Digital banking and payment platforms that require large, well-governed delivery teams and cloud expertise.
Overview: LTIMindtree was formed by the merger of L&T Infotech and Mindtree, whose roots lie in Bangalore. The combined business serves banks, insurers and payment providers with application development, data engineering and cloud services. Its financial services practice covers areas such as digital payments, open banking interfaces and customer-experience redesign. Clients often turn to it for programmes that need strong governance, security reviews and steady delivery across time zones. As with other large integrators, it works best for substantial scopes where compliance matters most.
6. Happiest Minds Technologies
Best for: Mid-market lenders and fintech firms seeking digital product engineering with a modern, agile approach.
Overview: Happiest Minds is a Bangalore-headquartered company built around digital-first services, including product engineering, cloud, security and analytics. Its banking and financial services group builds mobile banking experiences, payment integrations and customer journeys for lenders and fintech businesses. The company sits between boutique studios and giant integrators, offering more structure than the former and more flexibility than the latter. Teams are comfortable with microservices, API gateways and cloud-native designs, which suits payment products that must scale during sudden traffic spikes. Senior engineers stay close to client projects.
7. Thoughtworks
Best for: Companies that care about clean architecture, test-driven engineering and long-term maintainability of payment systems.
Overview: Thoughtworks is a global technology consultancy with a large engineering presence in Bangalore. It is known for agile delivery, continuous integration practices and a disciplined approach to software quality. Its financial services clients have included banks and payment businesses that wanted to replace brittle legacy systems with modular platforms. The consultancy often works as an embedded partner, pairing with in-house engineers and passing on practices. Pricing tends to sit at the premium end, which suits products where reliability is a core risk.
8. Sasken Technologies
Best for: Payment products that depend on mobile, embedded or device-level engineering rather than software alone.
Overview: Sasken is a Bangalore-based engineering services company with a heritage in telecom, semiconductors and connected devices. That background gives it an unusual edge for payment experiences that touch hardware, such as point-of-sale terminals, secure elements and mobile handsets. It also offers digital engineering and quality assurance services that apply to payment app testing across wide device ranges. Businesses building pure software wallets may look elsewhere first, whereas teams working at the boundary of device and transaction often find its depth useful. Long product lifecycles are familiar territory.
9. ThoughtFocus
Best for: Fintech startups and financial institutions needing specialised teams for payments, compliance and operations.
Overview: ThoughtFocus is a technology and operations firm serving the financial sector, with a significant delivery base in Bangalore. Its work spans payment systems, trade and treasury technology, regulatory solutions and process automation. The company positions itself around financial services rather than general software, so its teams tend to understand settlement cycles, reconciliation and sanctions screening without lengthy briefing. That domain familiarity can shorten discovery and reduce rework, particularly on projects where operations and engineering must change together. Dedicated teams are available for both build and run phases.
10. Juspay
Best for: Businesses that want to improve checkout success rates and manage several payment providers through one layer.
Overview: Juspay is a Bangalore-born payments technology company best known for checkout and orchestration products used by major Indian consumer brands. Rather than building a bespoke app from scratch, it supplies infrastructure that routes transactions across gateways, improves success rates and supports UPI, cards and wallets. Merchants with heavy traffic often adopt such a layer to cut failed payments. It is a product company first, so it fits teams that prefer to integrate proven components over commissioning fully custom engineering.
11. Razorpay
Best for: Online businesses and startups that need a ready payment gateway with banking, payroll and subscription tools.
Overview: Razorpay is a Bengaluru fintech company that lets businesses collect, process and pay out money online. Its range covers gateway services, subscription billing, payment links, business banking and lending. Developers value the documentation and SDKs, which shorten integration time for web and mobile apps. Like Juspay, it is a platform provider rather than a custom development agency, so it works well alongside an app development partner who handles the product experience while Razorpay handles the underlying money movement and settlement.
12. iJeeva Software Solutions
Best for: Banks and mid-sized organisations wanting a dedicated payment platform or gateway built around their own rules.
Overview: iJeeva is a Bangalore-based software company that has built a reputation around enterprise payment platforms and gateways. Its customers have ranged from small businesses to banks, which suggests flexibility across different scales and compliance needs. The firm concentrates on payment-specific architecture, including switching, routing and merchant management modules. Because it serves a narrow slice of the market, it can be a sensible option for organisations that want a specialist rather than a generalist and are prepared to define their requirements carefully.
13. Innoviti Payment Solutions
Best for: Retailers and banks that need in-store payment, EMI and merchant acquiring technology.
Overview: Innoviti is a Bangalore-headquartered payments company that develops payment processing and credit distribution software. It is associated with in-store technology, including terminal integration and instalment payment options at retail checkout. That makes it relevant for businesses connecting physical outlets with digital payment flows. Its offerings are product-led, so engagement usually centres on integrating and configuring existing solutions with a client's systems. Retail chains wanting consistent EMI and card experiences across many stores often find this area useful. Its terminal and acquiring experience is relatively rare among app-focused vendors.
14. Tarams Software Technologies
Best for: Startups wanting a mid-sized product engineering team with strong mobile and cloud skills at a moderate cost.
Overview: Tarams is a Bangalore-based product engineering company that builds mobile, web and cloud applications for clients in India, the United States and Europe. Its teams are used to taking an idea through design, development and scaling, which suits early fintech products that need an app, a backend and an admin console together. The company operates at a size that allows closer founder access than large integrators usually offer. Payment compliance work should be scoped early, since requirements vary by product type.
15. Aalpha Information Systems
Best for: Small and growing businesses seeking affordable custom mobile apps with payment integrations built in.
Overview: Aalpha Information Systems is a custom software and mobile app development company serving clients across several regions. It builds apps for sectors such as healthcare, logistics, retail and finance, often including gateway integration, wallets and subscription billing. The company's breadth means payments rarely appear in isolation but as a feature inside a broader product. That approach helps businesses where checkout is one component of the whole experience. Buyers should review recent fintech case work and security practices directly before committing to any engagement.
How to Narrow Down Your Shortlist
Start with the type of problem you actually have. A bank replacing a core system and a startup launching a wallet need entirely different partners. Large integrators bring governance and scale, boutique engineering firms bring speed and founder access, and platform providers such as gateway and orchestration companies remove the need to build certain layers at all.
Many successful products combine these. A startup might commission a custom app from a development company while relying on a gateway provider for settlement. Ask each candidate for references from projects with similar transaction volumes, and request a short technical discussion with the engineers, not only the sales team.
Briefs in 2026 also look different from those of a few years ago. Buyers increasingly ask for UPI on credit lines, card tokenisation, account-aggregator data flows and machine-learning fraud scoring as standard requirements rather than optional extras. Regulators have tightened expectations around grievance handling and data storage, and users now abandon apps that fail twice in a row. A partner who raises these points unprompted, and explains how they would be handled in your architecture, is usually thinking about your product and not only about the contract.
Frequently Asked Questions
How long does it take to build a payment app? A basic wallet or UPI-style app commonly takes three to six months, while multi-bank platforms with lending or rewards can take nine months or longer.
Do I need a licence to launch a payment app in India? It depends on the model. Apps that hold customer funds or issue prepaid instruments generally require authorisation from the Reserve Bank of India, whereas apps built on a licensed partner's rails may not. Always confirm with a legal advisor.
Should I build a custom gateway or integrate an existing one? Most new products integrate an existing gateway, since it reduces compliance burden and launch time. Custom gateways make sense mainly for banks and very high-volume businesses.
