Information Security Management System (ISMS) procedures following ISO 27001 best practices.
Infrastructure supports deployment in accordance with applicable regulatory requirements.
We provide a developer-friendly payment infrastructure layer that allows businesses, startups, and marketplaces in India to accept digital payments seamlessly through a single unified API. Our platform aggregates and orchestrates multiple leading payment providers, enabling full support for popular transactional methods including UPI routing, secure card processing, major netbanking channels, and digital wallets.
Integration takes only a few minutes due to our developer-first REST APIs, comprehensive documentation, and sandbox testing systems. While standard merchant accounts can be configured rapidly using secure API keys, complex production environments requiring advanced cloud microservices, tailored smart retry rules, or custom webhook notifications may take slightly longer for full data validation and operational alignment.
Yes, our architecture features a native UPI-ready infrastructure and tokenized routing engine. To safeguard user data and maintain compliance, all sensitive information is encrypted during communication and never stored in plain text. This allows local Indian enterprises, online marketplaces, and retail shops to manage complex checkouts safely while utilizing tokenized storage to optimize card processing flows.
Our orchestration engine relies on dynamic real-time criteria to maximize payment success rates and limit failures. Factors such as current gateway response times, historical provider uptime, and smart failure detection determine the automatic routing pathways. If an unexpected gateway failover occurs, our integrated logic reroutes the transaction to secondary banking partners without breaking the customer checkout workflow.
Yes, Paisly coordinates closely with payment networks and major banking infrastructure partners regulated by the Reserve Bank of India (RBI). As an established Technology Service Provider (TSP), we manage the technical compliance layers, cloud security requirements, and auditing frameworks, making it easier for your platform to achieve standard merchant verification and initiate automated settlement distributions.
The centralized portal provides full visibility into your transactional environment out of the box. Merchants have access to real-time payment monitoring, immediate refund management controls, detailed settlement reports, and automated ledger reconciliation systems. Additionally, developers can configure live webhook events within the dashboard settings to receive automated notifications regarding status changes.
Our flexible payment models accommodate an extensive array of industries and corporate operational scales. Key business sectors include SaaS platforms requiring monthly subscription billing, marketplaces setting up split seller settlements, e-commerce stores launching digital checkouts with EMI options, as well as healthcare and educational systems needing robust fee collection, insurance payout mechanisms, and institutional ledger auditing.
Our enterprise-ready framework is engineered as a highly scalable microservices ecosystem using cutting-edge, cloud-native technologies. The core backend relies on Java Spring Boot, while Kafka handles streaming data lines, Redis optimizes in-memory caching performance, and MongoDB manages document data storage. The entire infrastructure is orchestrated within Kubernetes clusters deployed over secure Google Cloud Platform environments.
We help payment providers, financial institutions and enterprise businesses build secure, scalable and reliable payment infrastructure through modern technology.
