Cevrynt is now a Stripe partner. On 22 October 2026, Stripe approved the application from Cevrynt, Inc. to join the Stripe Partner Ecosystem, the program Stripe runs for companies that build on, integrate with and deliver services around Stripe. For teams that run revenue through Stripe, it means one more way to check who you are hiring; it does not change who owns your code, your Stripe account or your data.

This post is an announcement, but most of it is a guide. We explain what the Stripe Partner Ecosystem is in Stripe's own terms, the difference between a company being a partner and individual engineers holding Stripe certifications, how to choose a Stripe integration partner for your project, the questions worth asking and the red flags worth walking away from. At the end we describe, briefly and plainly, how our own engagements start. If you only want the short version: partner status is a useful filter, not a guarantee, and the questions in the middle of this article matter more than any badge.

From here, this article is about Cevrynt

What does it mean that Cevrynt is a Stripe partner?

It means Stripe reviewed Cevrynt, Inc. as a company and accepted it into the Stripe Partner Ecosystem. Stripe's documentation describes the program as one that "provides benefits, incentives and resources" to partners who integrate with, extend and build on Stripe. Partners join through an application, meet the requirements of the track they apply to, and accept Stripe's partner agreement. You can read the full description on Stripe's partner documentation.

Our application was for the services side of the program: we design, build, fix and migrate Stripe integrations for other companies. Being a partner gives us access to Stripe's partner portal, training, partner support and co-branding guidelines, and it lets us use the Stripe Partner badge under those guidelines. It does not make Cevrynt part of Stripe, and Stripe does not endorse any particular project we deliver. We are an independent engineering company that builds on Stripe, which Stripe describes as financial infrastructure for the internet.

Stripe also lists partners publicly in its partner directory. Our profile is now live: you can see Cevrynt in the Stripe Partner Directory, with the areas we work in and examples of our Stripe work. That listing, published by Stripe, is the independent record of the partnership; this post explains what it means.

What is the Stripe Partner Ecosystem?

The Stripe Partner Ecosystem is Stripe's program for third-party companies that help businesses adopt and run Stripe. According to Stripe's documentation, it has four primary tracks, plus a fifth that is available by invitation only:

  • Services — system integrators, software development agencies, digital agencies and similar firms that advise on, implement, deploy or offer services with Stripe. This is the track that matters if you are hiring someone to build your integration.
  • SaaS platforms — software companies that embed Stripe products inside their own platform so their customers can take payments or use other financial services.
  • Apps — companies that build integrations between Stripe and other systems and list them on the Stripe App Marketplace.
  • Payment methods — providers of alternatives to card payments that let businesses support local ways to pay.
  • Technology — software and cloud providers with prebuilt solutions; Stripe lists this track as invitation only.

Stripe's docs describe two tiers: Partner and Premier. All partners go through a vetting process and enter at the Partner tier; Premier is a selective tier that requires nomination by a Stripe partner development manager. Separately, Stripe awards specializations for proven expertise in particular products, industries or solutions, again by nomination and assessment. Cevrynt has joined at the Partner tier. We do not hold Premier status or any specialization, and we will not imply otherwise.

For the services track, Stripe's services partner page sets a concrete baseline: a partner must maintain a minimum of two certified individuals. That requirement is the reason the next section exists. A services partner's status depends on its people holding Stripe certifications, but the two things are still different and worth checking separately.

Stripe partner status vs. Stripe-certified engineers

A Stripe partner is a company. A Stripe certification belongs to a person. The two are easy to blur on a sales page, and the difference matters when you are deciding who to trust with your payment flows.

Stripe's training and certification page describes two types of certification, architect and developer, each at associate or professional level. The professional implementation architect exam, for example, is aimed at people with two or more years of experience designing and managing Stripe implementations, and covers account structures, funds flows, third-party integrations and data migration. Certifications are earned by individuals through an exam or a coding challenge, and they stay with that individual if they change employer.

At Cevrynt, the certifications belong to three named people. Arindam Pradhan, our founder, is a Stripe Certified Professional, Implementation Architect. Anupam Pradhan is a Stripe Certified Professional, Payments Architect; his certification was earned on 5 August 2026 and is valid to 5 August 2028. Subhadip Giri, a full stack developer with more than five years of experience, is also a Stripe Certified Professional, Payments Architect. The partnership belongs to Cevrynt, Inc. We say it this way everywhere because it is accurate: the company is the partner, and these three people hold the certifications.

Partner status belongs to the company. Certifications belong to named people.

Why should a buyer care? Because the two answer different questions. Partner status answers "has Stripe looked at this company and accepted it into its program?" A certification answers "has this specific person passed Stripe's exam on how to design or build a Stripe integration?" Neither answers "will the person assigned to my project be one of the certified people, and have they built something like my integration before?" That last question is the one you have to ask directly.

How to verify both

  • For partner status, ask the company when it was approved and which track it is in. Stripe's partner directory is the place to confirm it.
  • For certifications, ask for the names of the certified people, the exact certification each holds and its validity dates. A firm that says "we are Stripe certified" without naming anyone is describing its people loosely at best.
  • For your project, ask which of those people will design the architecture, who will review the code, and how much of their time your project actually gets.

What changes for our clients, and what does not

We want to be specific here, because announcements like this tend to promise more than they deliver.

What changes

  • A clearer channel to Stripe's partner resources. Partners get a partner portal and partner support from Stripe. When a project raises a question about how a product behaves, we have a defined route to ask, alongside Stripe's public documentation.
  • Access to Stripe's partner training. Stripe's program includes technical training and certifications. We use it to keep our certified people current with how Stripe products change.
  • An easier way to check us. You no longer have to take our word for our Stripe experience alone. Stripe vetted the company, three named people hold Stripe certifications, and our Stripe Partner Directory profile is public.

What does not change

  • You own everything. The code lives in your repository, the Stripe account is yours, and access is set up in your name with least privilege. Partner status does not give Stripe or us any new rights over your account or data.
  • Stripe still decides what Stripe supports. Product availability depends on country, account, device and configuration. We cannot make a Stripe product available where Stripe does not offer it, and partner status does not change Stripe's review of your account.
  • Pricing is still written and scoped. Every Stripe project is scoped and priced in writing after a technical review. We do not publish Stripe project prices and we never quote Stripe's own fees; those are between you and Stripe.
  • The engineering standard. We already ran every flow in Stripe test mode before go-live, including failures and replayed webhooks. That was true before 22 October and remains true now.

What does a Stripe integration actually touch?

Choosing a Stripe integration partner is easier when you know what the work covers. Most teams think of a Stripe integration as the checkout form. In practice, a production integration touches four areas of your business, and problems usually appear where two of them disagree.

Illustrative. The four areas a production Stripe integration reaches into.
  • Product. The pages and screens a customer uses: checkout, plan selection, upgrade and cancel flows, the in-person payment screen on a kiosk. This is the part people see, and usually the smallest part of the work.
  • Backend. The server code that creates and updates Stripe objects and keeps your own database in step. Stripe supports idempotency keys so a request that is retried after a timeout does not create a second object; a backend that does not use them can double-charge or double-create under poor network conditions.
  • Webhooks. Stripe tells your system what happened through events delivered to your webhook endpoint. Stripe's webhook documentation is explicit that delivery order is not guaranteed and that the same event can arrive more than once, so a handler has to verify signatures, deduplicate by event ID and avoid depending on order.
  • Finance records. Invoices, refunds, disputes, payouts and the reports your finance team reconciles against your bank and your own ledger. An integration that takes payments correctly but leaves finance reconciling by hand is not finished.

A good partner asks about all four in the first conversation. If the discussion stays on the checkout page, the hard parts are being left for later, which usually means after launch.

How to choose a Stripe integration partner

Whether you hire a Stripe partner, a freelance Stripe developer or an in-house engineer, the same questions separate people who have shipped production payment systems from people who have followed a quickstart. These are the questions we would ask if we were on your side of the table.

Questions about the people

  1. Who exactly will work on our integration? Get names, not a team description. Ask how much of each person's time your project gets.
  2. Which of those people hold Stripe certifications, and which ones? Architect certifications focus on design decisions; developer certifications focus on building. Both are useful, and neither replaces experience with your specific product.
  3. What have they built that resembles ours? A marketplace paying out to sellers is different from a subscription product, and both are different from an in-person kiosk. Ask for a description of a comparable project and what went wrong in it.

Questions about the design

  1. Will we get a written architecture before you build? It should name the Stripe objects you will use, the webhook events you will handle, where state lives and what happens when each step fails.
  2. Which webhook events will you handle, and how do you deal with duplicates and ordering? A confident, specific answer here is one of the best signals you can get in a first call.
  3. How will our own records stay in step with Stripe? For a subscription product, ask how access is granted and removed. For a marketplace, ask how transfers and payouts reconcile with your orders.
  4. What is the migration plan, if we are moving from another system or another Stripe account? Ask how customers avoid being charged twice or not at all during the switch. Stripe documents its own subscription migration options; a partner should know which applies to you.

Questions about delivery and ownership

  1. Where will the code live, and who owns it? The answer should be your repository, from the first commit.
  2. What access do you need to our Stripe account? The answer should be the least access that does the job, granted to named people, with restricted keys where possible. Stripe's guidance on API key handling is worth reading before anyone asks you for one.
  3. How will you test before go-live? Expect a plan for Stripe test mode or a sandbox that covers failed payments, declined cards, retries and webhooks delivered out of order, not only the happy path.
  4. What does go-live look like, and how do we roll back? A cut-over should be planned, with a way back if something unexpected happens.
  5. What happens after launch? Ask who watches for failed webhooks and payment errors, and for how long.

Red flags when hiring a Stripe developer or partner

Most bad Stripe projects were visible as bad in the first two weeks. These are the warning signs we see most often when we are called in to repair an integration someone else built.

  • They ask for your live secret key by email or chat. Nobody needs a raw production secret sent in a message. Access should be granted inside your Stripe account, to named people, with the least permission that works.
  • They promise a Stripe product will work in your country or on your device without checking. Availability of products such as Connect capabilities or Tap to Pay depends on country, account, device and configuration. The honest answer starts with "let us check Stripe's documentation for your case."
  • They quote a fixed price before seeing anything. A checkout form can be priced from a description. An integration with subscriptions, webhooks and reconciliation cannot, until someone has looked at your code and your account.
  • Webhooks are an afterthought. If the plan treats the redirect after checkout as proof of payment, or has no answer for duplicate and out-of-order events, the integration will drift from Stripe's records.
  • There is no test plan beyond a successful payment. A demo that charges a test card once proves very little. Ask to see a declined card, a failed renewal and a refund flow working before launch.
  • They claim badges they cannot name. Any claim to a Stripe tier, specialization or certification should come with specifics you can check. Vague claims of being "Stripe approved" or "Stripe certified" with no names attached are a reason to ask more questions.
  • The code lives in their account. If the repository, hosting or Stripe account sits in the vendor's name, you do not fully own your payments system.

What a good Stripe engagement looks like

There is no single correct process, but good Stripe engagements share a shape. Work moves from understanding what exists, to a written design, to implementation, to testing that deliberately tries to break things, to a planned launch, to watching what happens afterward. Each step produces something you can read or click, so you can judge progress without taking anyone's word for it.

The path a Stripe engagement should follow, from audit to monitoring.
  1. Audit. Review the current integration, the data model and the Stripe account setup. For a new build, this is a review of the product requirements and the systems Stripe will connect to. The output is a written list of what exists, what is risky and what is missing.
  2. Written architecture. A design document that names the Stripe objects, the webhook events, where state lives in your system and how each failure is handled. This is the document you approve before building starts.
  3. Implementation. Built in your codebase, in your repository, reviewed weekly. You should be able to see working software on a staging environment as it progresses.
  4. Test-mode verification. Every flow exercised in Stripe test mode or a sandbox, including declined cards, failed renewals, refunds, disputes where relevant and webhooks replayed out of order. Stripe's CLI can forward events to a local endpoint and trigger test events, which makes these cases repeatable.
  5. Controlled go-live. A planned cut-over, with a rollback path agreed in advance. For migrations this often means moving customers in batches rather than all at once.
  6. Monitoring. Alerts on failed webhook deliveries and payment errors after launch, so problems are seen by the team before they are seen by customers or by finance.

One small example of what "test the failure cases" means in code. A webhook handler should refuse any request whose signature does not verify, and it needs the raw request body to do that. Many frameworks parse JSON automatically, which breaks verification; it is one of the most common reasons a webhook endpoint fails in production after working in a quick test.

Verifying a Stripe webhook signature in Express
import express from "express";
import Stripe from "stripe";

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY);
const endpointSecret = process.env.STRIPE_WEBHOOK_SECRET; // whsec_...
const app = express();

// Use the raw body: signature verification fails on parsed JSON.
app.post("/webhooks/stripe", express.raw({ type: "application/json" }), (req, res) => {
  let event;
  try {
    event = stripe.webhooks.constructEvent(req.body, req.headers["stripe-signature"], endpointSecret);
  } catch (err) {
    return res.status(400).send(`Webhook signature verification failed: ${err.message}`);
  }

  // Acknowledge quickly; do the real work from a queue, deduplicated by event.id.
  enqueueStripeEvent(event.id, event.type);
  res.sendStatus(200);
});

The handler does three things and nothing else: it verifies the signature, it hands the event to a queue keyed by event ID so duplicates are processed once, and it returns a success status quickly. Stripe's documentation recommends exactly this pattern of returning a 2xx response before any complex logic. We go deeper on the queue, deduplication and ordering in our guide to Stripe webhooks best practices.

Common Stripe projects, and where they usually go wrong

The same few kinds of project make up most Stripe work. Each has a characteristic failure, and knowing it in advance is half of choosing the right partner.

Subscriptions and invoicing with Stripe Billing

Billing projects cover recurring prices, trials, coupons, upgrades and downgrades, invoices and renewals. The common failure is subscription state drift: Stripe says a customer has paid and your app still says unpaid, or a failed renewal never removes access. The fix is almost always in how webhook events update your own records, and in having a clear written rule for what access a customer has in each subscription state. Our Stripe Billing service covers this work.

Marketplaces and platforms with Stripe Connect

Connect projects onboard sellers or service providers, split payments and pay them out. The first decision, which charge type to use, shapes who is responsible for refunds and disputes, whose name appears on the customer's statement and how funds move. Getting it wrong is expensive to undo after launch. The common failure is a funds flow that nobody wrote down, so charges, transfers and payouts stop reconciling with orders. See our Stripe Connect service.

In-person payments with Stripe Terminal and Tap to Pay

Terminal projects take card payments in person through a reader or, where supported, Tap to Pay on a phone or tablet. Tap to Pay availability depends on country, device and account, so the first step is always checking Stripe's documentation for your case. The common failure is architectural: a kiosk or POS app whose interface is a web app, while the payment has to be collected natively on the device. We built exactly that for Megapos Ltd, a point-of-sale company: a Flutter WebView kiosk with a Node.js and Express backend and a native Kotlin bridge to Stripe Terminal Tap to Pay, where the PaymentIntent's client secret passes from the web layer to Flutter to Kotlin so the payment is collected natively without exposing keys in the web app. The case study has the details, and our Stripe Terminal service covers this work.

Webhook repairs and migrations

Some projects are not new features at all. They are integrations that mostly work but miss events, or moves from a legacy billing system or another Stripe account. The common failure in migrations is timing: a customer charged by both systems during the switch, or by neither. The safe pattern is a dry run, a mapping you can inspect, a cut-over in batches and a reconciliation check afterward. Our hub page for Stripe payments engineering covers repairs and migrations.

How Cevrynt starts a Stripe engagement

Cevrynt, Inc. is a Delaware company with an engineering team led by Arindam Pradhan, who has built production software since 2018, and four senior engineers with six or more years each. We work remotely from India with overlap into US and European hours. Our engagements follow the path above: an audit of what exists, a written architecture you approve, implementation in your codebase with weekly reviews, verification of every flow in Stripe test mode, a controlled go-live with a rollback path, and monitoring afterward.

Every Stripe project is scoped and priced in writing after a technical review, so you see the plan and the price before anything is billed. The work happens in your repository and your Stripe account, with least-privilege access. If you want to talk about an integration you have or one you need, book a Stripe consultation, or send the details through our enquiry form.
