Payment Gateway Integration in Kolkata
e10 Infotech handles payment gateway integration in Kolkata with Razorpay, PayU, Cashfree, Stripe and PayPal, including UPI.
Payment gateway integration that reconciles at the end of the month
e10 Infotech Private Limited integrates payments into websites, stores and applications. Taking the first payment is the easy part. The work that matters is what happens afterwards: failed transactions that actually succeeded, refunds, partial captures, disputed charges, settlement reports that must match your books, and customers who close the browser mid payment. Businesses in Kolkata come to us when they want this handled properly.
What we implement
- Indian gateways: Razorpay, PayU, Cashfree, CCAvenue, Instamojo and bank gateways
- International: Stripe and PayPal for cross border and subscription billing
- Methods: UPI intent and collect, cards, netbanking, wallets, EMI and pay later
- Recurring billing with mandates, retries, dunning and customer portals
- Reconciliation exports that match settlement files to orders and invoices
Reliability and compliance
We use server side verification of every payment signature, webhooks as the source of truth rather than browser redirects, idempotent order handling so one payment can never create two orders, and audit logs for every state change. Card data never touches your server, which keeps your compliance burden where it belongs.
Works well with
Payment work supports Ecommerce Development, WooCommerce Development and Shopify Development. It is often part of Web Application Development and Mobile App Development, and connects to accounting through API Integration.
Working with businesses in Kolkata
Work for clients in Kolkata runs remote first: a named team, a scope agreed in writing before anything starts, and regular demos you can hold us to. Working hours are arranged to overlap your day, and everything is delivered in English.
Commercial context changes from one city to the next, so we start by looking at what comparable businesses in Kolkata already do, what they charge and where the gaps sit. That research shapes scope before production work begins.
You get one point of contact, senior people on the delivery, and reporting tied to enquiries and revenue rather than activity. Businesses in Kolkata and across the wider region are supported on the same terms.

Answers before you ask
Everything worth knowing about Payment Gateway Integration in Kolkata.
Which payment gateway should we choose?
It depends on your settlement needs, transaction mix, chargeback profile and pricing. We compare two or three against your actual volumes.
How long does integration take?
A standard checkout integration takes three to five working days. Subscriptions, split payments or marketplace payouts take longer.
Can you add UPI as a payment option?
Yes, both intent based flows on mobile and collect requests, which usually improve conversion in India.
Do you handle recurring subscriptions?
Yes, with mandates, automatic retries, dunning emails and a portal where customers can pause or cancel.
What happens if a payment fails but money is deducted?
We reconcile against webhook and settlement data, then either capture the order or trigger a refund automatically, with the case logged.
Is our checkout PCI compliant?
Card details are entered on the gateway side, so your servers never store them. We follow the gateway integration requirements exactly.
Can you integrate cash on delivery rules?
Yes, with pincode serviceability, order value limits, partial prepayment and verification steps to reduce fake orders.
Do you support international payments?
Yes, with multi currency pricing, Stripe or PayPal, and the documentation your bank requires for inward remittance.
How do refunds work?
Refunds are triggered from your admin or store, tracked to completion through webhooks, and reflected in reports and invoices.
Can payments be split between vendors?
Yes, using route or split settlement features for marketplaces, with commission rules and payout reporting.
Will settlement reports match our accounting?
That is the goal. We build exports that map settlements, fees and taxes to orders so reconciliation is a check rather than an investigation.
How do we start?
Tell us your platform, expected volume and preferred gateway. We confirm the integration approach and quote it.
Do you offer Payment Gateway Integration in Kolkata?
Yes. e10 Infotech delivers Payment Gateway Integration for businesses in Kolkata and across the wider region, remote first with a named team and a scope agreed before work starts.
How do you run Payment Gateway Integration projects for clients in Kolkata?
Working hours overlap the Kolkata business day, communication is in English, and you get one point of contact with reporting tied to enquiries and revenue rather than activity.
