How to Build a Subscription Payment Connector: Basic vs Advanced Setup

Written by Maciej Stempniak | Oct 8, 2025 10:24:28 AM

For any D2C subscription business, the journey begins with a simple goal: selling a digital product online. It seems straightforward enough. You choose a payment provider, embed a form, and add a 'Buy Now' button. Payments start coming in. Job done, right?

Not quite. While a basic setup can process a simple, one-time transaction, it's merely the tip of the iceberg. For businesses serious about growth – especially those built on subscriptions and recurring revenue – that simple button hides a universe of complexity. What lies beneath the surface is what separates stagnant businesses from those that achieve high conversion rates, maximize customer lifetime value, and scale globally.

As we prepared to launch one of our latest connectors through Primer, it served as a powerful reminder of what it truly takes and how to build a robust D2C subscription payment solution.

Let's compare the "basic" setup with the "advanced" architecture required for D2C success.

 

The basic setup: the 10% you can see in subscription setups

A basic payment integration offers only the bare essentials for processing transactions. Typically, it includes:

  • A simple checkout form designed for one-time purchases.

  • Processing support for major credit cards, usually in a single currency.

  • Basic success or failure messages to confirm or reject payments.

While this might be sufficient for a hobbyist or a small-scale operation, it won't support the broader needs of modern subscriptions, such as recurring payments, multi-currency transactions, or subscription lifecycle management. 

As a result, it can create costly roadblocks, leading to lost revenue, frustrated customers, and increased operational burdens as your team struggles to patch together workarounds. For a thriving brand, a more robust payment solution is essential to effectively manage the entire customer lifecycle and scale without limitations.

 

 

The advanced payment architecture: the 90% that drives growth for subscription brands

An advanced subscription payment connector is a strategic asset designed for retention and conversion. It handles the intricate edge cases that are not just possibilities, but certainties in the world of recurring billing.

 

Here’s how a robust payment architecture empowers subscription brand growth: 

 

1. Supporting a flexible product catalog: managing trials and gifting

Your business model isn't static, so why should your payment system be? A robust subscription payment connector must seamlessly handle:

  • Diverse product types: One-time purchases, live event access, non-renewing passes, and tiered subscriptions.

  • Customer acquisition models: Effortlessly manage free trials (authorizing a card without charging) and 100% discounts, tokenizing payment details for future renewals.

  • Gifting: Allow users to purchase any of these products as a gift for someone else, a crucial revenue stream for media and entertainment, health and fitness, and edtech. 

A flexible payment system that can adapt to these different scenarios is essential for maximizing revenue and customer satisfaction.

 

2. Mastering the subscription lifecycle for maximum retention

The real value in D2C subscriptions is in recurring revenue, and protecting it is crucial. Building an advanced connector helps you strategically protect and optimize this recurring revenue through every stage of the customer journey.

  • Smart dunning and attempt maximization: Failed payments are an inevitable part of any subscription business. A basic system simply fails to recover payments once they fail. However, an advanced system employs smart dunning logic – an intelligent payment retry logic based on specific failure codes – to maximize the chances of successful payment recovery. Aggressive, naive retries can lead to being blocked by Payment Service Providers (PSPs); a smart approach thoughtfully salvages revenue that would otherwise be lost.

  • Lifecycle events: Customers today expect flexibility and control over their subscriptions. A robust payment system seamlessly manages critical lifecycle events such as pauses, subscription resumes, plan switches, and even complex mid-cycle upgrades. For instance, an upgrade might involve charging a user for a new plan while instantly refunding a prorated amount for their old one. Handling these intricate scenarios automatically is critical for both a smooth user experience and efficient operations.

  • Automatic payment data storage, such as Network Tokens and Account Updater, to keep processing recurring payments even when the cardholder’s card details have expired or been lost

By intelligently managing these crucial points, you not only improve customer satisfaction but also significantly boost your overall subscription retention rates, ensuring a stable and growing revenue stream.

 

3. Optimizing for global conversion

Getting a customer to the checkout page is only half the battle. Winning the conversion is what matters.

  • Multi-currency and localization: Displaying prices in a customer's local currency is essential for building trust, reducing friction, and boosting conversion rates. The checkout experience should be fully localized in their language. 

  • Local payment methods: Offering customers their preferred local payment methods (for example, PIX in Brazil) is crucial. It builds trust, offers familiarity, and significantly reduces cart abandonment by allowing customers to pay with methods they know and use daily.

  • Intelligent payment routing: Different payment providers excel in different regions. An advanced setup can intelligently route transactions to the best PSP based on the customer's country, currency, or card type, maximizing success rates. It can also seamlessly offer local payment methods alongside global options.

  • Express wallets: Support for Google Pay and Apple Pay is non-negotiable. These methods dramatically reduce friction and can boost conversion rates by simplifying the payment process to a single tap.

 

4. Automating financial operations

The work doesn't stop after the payment is made. A scalable business needs automated back-office operations.

  • Unified refund and dispute management: Refunds can be initiated by your support team, the customer, or even as part of an automated plan switch. Chargebacks are initiated by the customer's bank. An advanced connector centralizes these events, ensuring your data is always accurate and manual reconciliation is eliminated, no matter the origin of the dispute.

  • Accuracy and security: From handling partial refunds to securely logging every transaction for troubleshooting, a robust system provides an auditable, reliable source of truth. It’s built on a scalable, monitored infrastructure that you can trust during peak demand, like a special promotion or a live event streaming.



 

The real solution for robust payment connectors: technology first, service on top

As you can see, building and maintaining a truly effective payment infrastructure is a monumental task. It requires deep, ongoing expertise that can distract your team from focusing on your core product. This is where a D2C subscription payment solution comes in, offering two distinct but complementary solutions.

 

1. The technology solution: an advanced payment platform for subscription businesses

First and foremost, the problem of complexity requires a powerful technology solution. Instead of building all this logic from scratch, you can integrate with a platform like Cleeng that has already solved the problem of complex technical challenges.

Our platform provides the advanced payment architecture, the connectors, the lifecycle logic, and the automation as a ready-to-use solution. By integrating with Cleeng, your team is freed from the enormous engineering challenge of building and maintaining this infrastructure. You get all the benefits of a world-class system (from smart dunning to lifecycle management) while focusing on what you do best: creating great content and products.

 

 

2. The complementary service: the Merchant of Record (MoR)

But what about the complexity beyond the code? Managing global sales taxes, currency conversions, fraud liability, and navigating intricate payment regulations is an entirely different operational challenge.

This is why opting for a payment solution with a built-in Merchant of Record (MOR) is great strategic move. 

When you operate under a MOR model, the solution provider becomes the legal entity selling to your subscribers, taking on the full financial and legal responsibility for every transaction. This includes:

  • Calculating, collecting, and remitting global sales taxes (VAT/GST).

  • Managing fraud and chargeback liability.

  • Handling currency conversion and relationships with banks.

  • Ensuring full payment compliance in all the regions you sell in.

The advanced payment connector is the engine that makes all this possible, but the MoR service is what allows you to hand over the keys and let someone else do all the driving. It transforms the immense operational burden of running a global D2C business into a simple, predictable revenue stream.

Conclusion: build or grow?

For any ambitious D2C brand, the choice becomes clear. Do you want to spend your resources building a complex, non-core function like a payments system? Or do you want to integrate with a specialist who provides not only the best-in-class technology but also the option to offload the entire operational headache?

At Cleeng, this is our world. Our platform and our optional MoR service are designed to handle every one of these challenges, enabling you to launch faster, scale globally, and maximize your revenue from day one.
