Overview

Payment website design for gateways, PSPs and payment platforms

Raqbash is a payment gateway website development company in India, handling payment website design and development for aggregators, PSPs and platforms that collect money on behalf of other businesses. We design the pricing, product and docs pages merchants compare, and we build the checkout, onboarding and dashboard code behind them. Processing, settlement and your licences sit on your side; our work is the part merchants see and touch.

A payment gateway is sold to two audiences at once: a finance lead comparing pricing, settlement and uptime, and a developer scanning your docs and sandbox to see how hard integration will be. If either hits friction, the merchant picks a competitor. We engineer both journeys, and we keep raw card data off your servers so your PCI-DSS scope stays as small as it reasonably can.

One team

Payment gateway website development and design, one team

Merchants judge a gateway on its pricing page and its docs. We design both and build both, so the sales story matches the sandbox.

Design

  • Pricing pages that show MDR, settlement cycles and international card fees in one comparable layout, using the rates you publish.
  • Docs information architecture: quick-start first, then guides, API reference and webhook events, each one click from search.
  • Checkout screens for cards, UPI intent and collect, netbanking, wallets and EMI, with failure states that tell the buyer what to do next.
  • Merchant dashboard flows for keys, refunds, disputes and settlement reports, tested with the finance users who reconcile them.
  • Status and trust pages laid out so an enterprise buyer finds incident history and security practices without emailing sales.

Development

  • Hosted fields and redirect patterns that keep raw card numbers off your servers and off your merchants' servers too.
  • A docs site generated from your OpenAPI spec, with versioned references, copyable samples and a self-serve test key flow.
  • Webhook delivery with signatures, retries and a replay tool in the dashboard, so merchants can recover events they missed.
  • Merchant sign-up with document upload, verification-provider calls and progress kept across sessions and devices.
  • Monitoring on checkout latency and error rates, with alerts sent to your on-call team before merchants raise tickets.

With payment website design and engineering in one team, the checkout your sales page describes is the checkout a developer actually integrates.

What we build

Payment Gateway Website Development Services We Offer

Six capabilities cover almost every payments brief we take on, from wiring a gateway into an existing site to building the full merchant-facing product an aggregator sells against.

  • Hosted & Drop-In Checkout

    Checkout built with hosted fields and drop-in elements so card data goes straight to the acquirer, keeping you at SAQ-A scope wherever possible.

  • Tokenization & Card-On-File

    Tokenized flows for saved cards and recurring billing, aligned with RBI's card-on-file approach, so you store tokens rather than PANs.

  • Merchant Onboarding & Dashboards

    Multi-step onboarding with document upload and verification-provider integration, plus an authenticated dashboard for keys, settlements and history.

  • Developer Docs & Sandbox

    A fast, searchable docs site with copy-paste snippets, a live sandbox and clear webhook references: the surface that shortens time-to-integration.

  • Webhooks & Reconciliation

    Idempotent APIs, signed webhooks with retries, and reconciliation views matching captures, refunds and settlements against your ledger.

  • Uptime, Status & Trust Signals

    A public status page and verifiable security signals: the proof enterprise merchants ask for before switching provider.

Scope, onboarding & docs

Checkout Scope, Merchant Onboarding & Developer Surface

Fintech checkout website design starts with hosted checkout that sends card data straight to your acquirer, plus tokenized card-on-file flows, merchant onboarding and dashboards, and the docs and sandbox a developer integrates against, then a money path that survives retries and reconciliation.

Hosted Checkout, Small PCI Scope

Hosted fields and drop-in elements send card data straight to the acquirer, with card-on-file tokenization aligned to RBI's framework so you hold tokens rather than PANs. That typically keeps you at SAQ-A, though your scope, SAQ level and attestation always remain yours to establish with your acquirer.

Merchant Onboarding & Dashboards

Multi-step onboarding with document upload and verification-provider integration, then an authenticated dashboard where merchants manage keys, watch settlements and pull transaction history without emailing your support team.

The Developer Surface

Fast searchable docs, copy-paste snippets, a live sandbox and clear webhook references. Time-to-first-successful-charge is the metric that decides adoption, and thin docs stall a developer at step one.

Reliability & Reconciliation

Idempotent APIs, signed webhooks with retries and replay handling, and reconciliation views that match captures, refunds and settlements against your ledger, so a finance team can trust the numbers.
  • PCI-DSS scope kept to SAQ-A/A-EP by never handling raw card data on your servers
  • Tokenization approach aligned with RBI's card-on-file (CoF) tokenization framework
  • Built with RBI Payment Aggregator / Payment Gateway guidelines in mind (no card storage, data localisation)
  • TLS everywhere, signed webhooks and audit logging on sensitive actions
  • Consent-gated analytics and data minimisation in line with India's DPDP Act

Why Raqbash

Choosing a Payment Gateway Website Development Company in India

Payments teams pick a payment gateway website design agency on proof: we build for both people evaluating you, the finance lead comparing settlement and the developer deciding how hard you are to integrate.

4.9 rated on Google Reviews

  • Built For Two Buyers

    A finance lead compares pricing and settlement while a developer reads your docs, at the same time. We design both journeys, because either one stalling loses the merchant.

  • PCI Scope Kept Small

    Raw card data never reaches your servers. Keeping scope minimal is a commercial argument here, not a compliance footnote: scope creep is what gets expensive.

  • Docs Developers Don't Fight

    Searchable reference, working snippets and a sandbox that behaves like production, because the integration experience is the product demo on this vertical.

  • Idempotent By Design

    Retries that don't double-charge, webhooks verified and replay-safe, and reconciliation that matches the ledger: the failure modes payments teams actually lose sleep over.

  • Fast Time-To-First-Charge

    We treat the path from landing page to a developer's first successful sandbox charge as a conversion funnel, and remove the friction in it.

  • Engineers Who Stay On Call

    The senior in-house team that built your checkout stays on it in IST, on a shared Slack or WhatsApp channel, accountable long after your payments product goes live.

Payments businesses

Payments Businesses We Build For

Payment startup web design stretches from an aggregator selling to enterprises to a shop wiring in checkout. These six sit at genuinely different scales, and the right build for one would be badly wrong for another.

How we work

How We Build Your Payments Product, Step by Step

Six transparent phases take your payments product from first conversation to live and supported, including a dedicated pass over the money path, where we run failure modes, retries, webhook replay and reconciliation before a single real charge.

    Discover

    We map your methods, acquirer, settlement cycles, merchant segments and developer audience.

  2. Step 02

    Design

    We design two journeys at once: a finance lead comparing, and a developer integrating.

  3. Step 03

    Develop

    We build checkout, onboarding, the merchant dashboard, and the docs and sandbox.

  4. Step 04

    Test The Money Path

    We run sandbox charges, failure modes, retries, webhook replay and reconciliation against the ledger.

  5. Step 05

    Launch

    We migrate carefully, verify Core Web Vitals and the status page, and go live with monitoring.

  6. Step 06

    Support

    We add methods, keep docs current, patch dependencies and watch webhook and error rates.

FAQ

Payment Gateway Website Development FAQs

Common questions from payments teams and merchants across India: integration, PCI scope, which gateways we work with, failed payments and reconciliation, what we do and don't build, cost and timelines.

How do you integrate a payment gateway into a website?

We integrate using hosted fields or a drop-in checkout so card data goes straight to the acquirer, then wire server-side capture, signed webhooks and reconciliation. This keeps raw card data off your servers and your PCI scope small.

Which payment gateways do you work with?

We work with Razorpay, Cashfree, Stripe, PayU and UPI, plus direct acquirer integrations. We choose based on your settlement needs, pricing, supported methods and the markets you sell into.

Does a payment gateway website need to be PCI-DSS compliant?

If your site touches cardholder data it falls in PCI-DSS scope. We build with hosted fields and tokenization so card data never reaches your servers, which typically keeps you at the lightest SAQ-A level. Your attestation still remains your responsibility.

How do you handle failed payments and reconciliation?

We build idempotent payment APIs, retry failed charges safely, verify signed webhooks, and provide reconciliation views that match captures, refunds and settlements against your ledger so finance teams can trust the numbers.

Do you build the payment gateway itself?

No. We build the merchant-facing product: checkout, onboarding, dashboards, docs and reconciliation views. The switch, the acquiring relationship and RBI Payment Aggregator authorisation are yours; we are not a payment institution and hold no such licence.

How much does payment gateway integration cost in India?

It depends on scope. Adding checkout to an existing site is a small engagement; a full merchant product with onboarding, KYC, a dashboard, docs and reconciliation is much larger. We quote a fixed scope after a short discovery call rather than a headline figure.

How long does a payment gateway website take?

Wiring checkout into an existing site takes days to a couple of weeks. A full merchant product with onboarding, dashboards, docs and reconciliation typically runs 10–16 weeks, delivered in phases with a working sandbox early.

Do you do both payment website design and development?

Yes. Our designers lay out pricing, docs and dashboard screens, and the same team handles the payment gateway website development: hosted checkout, webhooks, merchant onboarding and the docs build. Keeping both in one team means the integration steps a page describes are the steps the code supports. One quote covers the whole job.

Can you build a checkout component that merchants embed on their own sites?

Yes. We design and build embeddable checkout components that merchants theme with their own colours and fonts, plus the SDK snippets that load them. Card fields stay hosted by you, so a merchant's page never sees a card number. We test on low-end phones and inside in-app browsers, where most checkout bugs surface.
