Payment Gateway Integration — Website & eCommerce Launch

Overview

Payment Gateway Setup — Link is ITNS-Global's entry-level payment enablement service — a fully managed configuration of a payment link solution that allows your business to accept online payments instantly, without requiring a full eCommerce store or custom checkout integration.

For millions of Indian businesses — service providers, consultants, coaches, agencies, event organisers, and small retailers — the need to accept digital payments does not require a full eCommerce infrastructure. It requires a simple, reliable, professional mechanism to send a payment request to a customer and receive funds securely. That is precisely what this product delivers.

ITNS-Global configures your chosen payment gateway — Razorpay, PayU, Cashfree, or equivalent — sets up your branded payment page, creates your payment link workflow, embeds a payment button on your existing website, configures UPI and QR code payment options, and sets up automated payment confirmation and receipt emails. From setup to receiving your first payment typically takes fewer than 3 business days.

The Link variant is the ideal first step for businesses not yet ready for a full API-integrated checkout (P.16) — it provides immediate payment capability with minimal technical overhead, and can be upgraded to full API integration at any time without disruption.

What it includes

Payment Gateway Account Setup

ITNS-Global manages the complete gateway registration and KYC process with your chosen provider — Razorpay, PayU, Cashfree, or Instamojo. Business verification, bank account linking, settlement configuration, and test mode validation are all handled before your first live payment is processed.

Branded Payment Link & Page

A professionally branded payment page configured with your business name, logo, and service descriptions. Generate single-use or reusable payment links for specific amounts or open-ended payments — shareable via email, WhatsApp, SMS, or embedded directly on your website as a pay button.

UPI & QR Code Payments

UPI payment configuration covering all major apps — Google Pay, PhonePe, Paytm, BHIM, and bank UPI. A dedicated QR code generated for your business can be printed for in-person use, embedded in email signatures, or displayed on your website — covering both online and offline payment scenarios.

WhatsApp & Multi-Channel Link Sharing

Payment links configured for seamless sharing via WhatsApp Business, email, and SMS. Customers click the link, land on your branded payment page, complete payment in under 60 seconds, and receive an instant confirmation — the entire experience is professional, frictionless, and mobile-optimised.

Automated Confirmations & Receipts

Every successful payment triggers an automatic confirmation email to the customer with a payment receipt and invoice. Your business also receives an instant payment notification. No manual follow-up, no chasing confirmations — the entire post-payment communication is automated from day one.

Payment Dashboard & Reporting

Gateway dashboard configured and handed over so your team can track all transactions, view payment statuses, manage refunds, download settlement reports, and monitor payment success rates — all without involving ITNS-Global for day-to-day payment operations after handover.

Gateway API Setup & Secure Configuration

Complete gateway API credentials configuration in your server environment — API keys, secret keys, and webhook signing secrets stored securely using environment variables and server-side credential management. No sensitive keys exposed in front-end code. Sandbox environment configured first for testing, followed by production credential deployment after full QA sign-off.

Native Embedded Checkout UI

A branded, native checkout experience embedded directly within your website or application — no redirects to third-party payment pages, no loss of brand context at the most critical conversion moment. The checkout UI is styled to match your existing design system, with responsive layout optimised for mobile completion on every device.

Where it has been used

Professional Services

Consulting Firm — Invoice-to-Payment in One Click

A management consulting firm was chasing clients for bank transfer payments after issuing invoices — a process taking 7–14 days on average. After ITNS-Global set up their payment link solution, every invoice now includes a branded pay-now link. Clients pay within minutes of receiving the invoice, and the firm's average payment collection time dropped from 11 days to under 2.

11→2 days average payment collection time

Education & Training

Coaching Institute — WhatsApp Enrolments

A coaching institute running batches via WhatsApp used the payment link setup to collect course fees directly within their WhatsApp communication flow. Students received a payment link, paid via UPI or card in under a minute, and received automatic confirmation — replacing a manual NEFT process that required admin follow-up for every enrolment.

85% of enrolments now paid within 10 minutes of link receipt

Events & Hospitality

Event Organiser — Pre-Event Ticketing

An events management company required a fast way to collect ticket payments for corporate events without building a full ticketing platform. ITNS-Global configured fixed-amount and variable-amount payment links for different ticket categories — allowing the team to share links via email campaigns and collect fully reconciled payments before each event.

₹6.8L collected via payment links for a single event

Retail & Home Services

Home Services Provider — Field Payment Collection

A home services business (plumbing, electrical, cleaning) needed its field technicians to collect payment on-site without handling cash. ITNS-Global set up a QR code for each technician and a shared payment dashboard — customers scanned and paid via UPI on the spot, and all collections were visible in real time to the operations team.

100% digital payment collection — zero cash handling

Questions people ask

What is the difference between payment links and API integration?

Payment links require no development — you generate a link or QR code and send it to the customer. API integration embeds checkout inside your own website or app, so the customer never leaves your brand and payment status flows back into your systems automatically.

Do you handle the merchant account application?

We support the application and supply the technical documentation gateways request, but the merchant account is issued in your business name and the underwriting decision rests with the gateway.

Is card data stored on our servers?

No. Card details are captured by the gateway on PCI-compliant infrastructure and never touch your servers, which keeps your PCI scope minimal.

Can you set up recurring billing?

Yes — subscriptions, mandates and auto-debit are covered under API integration, including handling of failed payments and retry logic.

How long does integration take?

Payment links are usually live within two working days of merchant approval. API integration typically takes five to seven working days including sandbox testing.
