Stripe, PayPal, and Square integrations built for how your business actually collects money.
Most payment problems are not gateway problems. They are integration problems. We build the connection between your platform and your payment processor so transactions go through, webhooks fire correctly, and your team stops debugging checkout errors at 11 PM.

A SaaS founder came to us because her subscription platform was processing payments through a third-party plugin that broke every time Stripe pushed an update. Her developers had patched it four times in six months. Each patch took a weekend and held up two other features. The plugin was not the problem. The problem was that no one had ever built a proper, direct integration that she actually owned and could maintain.
Payment gateway integration is the work of connecting your application to a processor like Stripe, PayPal, or Square through their APIs in a way that handles the real complexity: failed charges, partial refunds, webhook verification, subscription billing cycles, currency conversion, and PCI compliance scope. A working checkout button is not enough. The integration has to hold up when a card is declined mid-subscription, when a customer disputes a charge, or when your business model adds a new pricing tier.
We have been building these integrations since 2015 across subscription platforms, marketplaces, booking systems, and e-commerce applications. We work entirely remotely with US-based businesses, using Laravel and Node.js on the backend and REST APIs to connect cleanly to whichever processor your business requires. You own every line of code when we are done. One honest limitation worth stating upfront: if your platform needs to process payments in more than a dozen countries with local payment methods (bank transfers, wallets, regional schemes), the scoping conversation gets significantly more involved, and we will tell you that before we quote anything.
For a standard Stripe or PayPal integration on an existing platform, you see a functional checkout flow in the staging environment within 2 to 3 weeks, not 2 to 3 months. We scope tightly before we write a line of code so the build phase has no ambiguity.
Every project is quoted at a fixed price based on a documented scope. You know the total cost before we start. If the scope changes, we discuss it openly and adjust the contract before doing additional work.
Most integration failures happen not at checkout but in the event layer. We build verified webhook handlers for every event your business cares about, including failed payments, subscription renewals, and refund confirmations, so your database and your processor stay in sync.
Whether your customers pay through a browser, an iOS app, or an Android app, we build the integration to match the platform. Stripe Elements for web, Stripe iOS/Android SDKs for mobile, and Square's in-person SDK if you have a physical component.
We build integrations that keep your application out of direct card data handling by using tokenization correctly. That keeps your PCI compliance scope at SAQ-A or SAQ-A-EP rather than the full SAQ-D, which saves you significant compliance overhead.
All code, all API keys structure, all documentation transfer to you at project completion. We sign an NDA on day one and a work-for-hire agreement that confirms IP ownership. There is no lock-in to us as an ongoing vendor unless you choose to keep us.
One-time payments, subscription billing, Stripe Connect for marketplace payouts, and Stripe Billing with usage-based pricing. We have built Stripe integrations for SaaS platforms, booking systems, and donation tools since Stripe's API was at version 2017-08-15.
PayPal Checkout, PayPal Subscriptions, and Venmo support for consumer-facing applications where PayPal is still the preferred option for a meaningful share of your customer base. We implement the Orders API, not the deprecated Payments API.
Square's Web Payments SDK for online checkout, Square Invoices for service businesses, and Square's in-person hardware SDK if your business takes payments at a counter or event. Particularly useful for retail and food service applications that need unified online and offline reporting.
We build the full subscription lifecycle: trial periods, upgrades, downgrades, proration, dunning for failed renewals, and cancellation flows. The business logic lives in your application, not inside the gateway, so you can change processors later without rebuilding your billing model.
If your platform connects buyers to sellers and takes a platform fee, we build the split payment and payout logic using Stripe Connect or PayPal's partner APIs. This includes KYC flow for onboarding sellers, payout scheduling, and 1099 data collection.
If you have an existing integration that is dropping webhooks, failing silently on certain card types, or not reconciling correctly with your accounting records, we audit the implementation and document exactly what is broken before proposing a fix. No guesswork, no unnecessary rebuilds.
No 47-slide proposal deck. No three-month discovery phase. Here is how a project moves from your idea to working software.
Start Your ProjectWe spend the first phase mapping your payment flows in detail: what triggers a charge, what happens on failure, how refunds are initiated, and how your accounting system reconciles. Most clients discover two or three edge cases during this conversation that their current setup handles incorrectly. That mapping becomes the spec we build against.
For customer-facing checkout flows, we design the payment UI to minimize drop-off at the payment step. That means clear error messaging (not just 'your card was declined'), logical field ordering, and mobile-friendly input handling. We present mockups for your review before writing any frontend code.
We build the integration in a staging environment that mirrors your production setup, using the gateway's test mode so every edge case can be triggered safely. We use Laravel or Node.js on the backend depending on your existing stack, and we structure the payment logic as a service layer so it is not tangled into your application controllers.
We test against every card scenario the gateway provides: successful charge, insufficient funds, expired card, disputed transaction, and webhook retry behavior. We also verify that your database state and the gateway's records match after each scenario, because silent mismatches are what cause reconciliation headaches in production.
We migrate from test mode to live keys in a controlled sequence, monitor the first 48 hours of live transactions closely, and stay available over Slack during your first live business day. If anything behaves unexpectedly, we catch it before it compounds.
After launch, we offer a structured support retainer that covers webhook failures, gateway API version upgrades, and new payment method additions. Most clients stay on a monthly retainer of 8 to 12 hours for the first few months, then scale down once the integration is stable. Response time on payment issues is within 4 business hours.
Our team is based in Gandhinagar, India, which means development work happens during your off-hours. You review progress in the morning rather than waiting for a same-timezone team to start their day. For time-sensitive integrations, that time zone difference is a genuine speed advantage.
The developer who maps your payment flows in the first week is the same person who writes the webhook handlers and fixes the edge case found in QA. We do not hand projects between teams or rotate staff mid-project, so context never gets lost.
We have been building software for US businesses since 2015, across more than 500 projects ranging from single-gateway checkouts to multi-currency marketplace platforms. That track record means we have already seen most of the failure modes before they appear in your project.
We use Slack for daily updates, Loom for recorded walkthrough videos so you can review progress asynchronously, and Zoom for scheduled calls that overlap with US Eastern and Pacific business hours. You are never waiting on a reply until the next morning.
Most of our clients are US-based businesses, but we have delivered payment integrations for companies in the UK, Canada, Australia, and across Southeast Asia. That breadth means we handle multi-currency and cross-border payment requirements without treating them as exotic edge cases.
We sign a mutual NDA before any scoping conversation, and the project contract explicitly assigns all intellectual property to you at delivery. Your payment integration code, your API key structure, and your webhook logic belong to you, not to us.
Common questions about payment gateway integration.
If your checkout has open questions around failed payments, webhook reliability, or a gateway migration, we will map the gaps and give you a clear picture of what a proper integration looks like for your platform.
