These features make Stripe an efficient choice for managing recurring billing and payment flows.
Recurring Billing Support
Stripe Billing offers tools to handle subscription revenue with flexible pricing options, including flat-rate, usage-based, and tiered models.
One of its standout features is Smart Retries, which uses AI to optimize retry times for failed payments. This feature has been shown to recover 11% more revenue. In 2023 alone, Stripe's recovery tools helped businesses reclaim over $3.4 billion in lost revenue.
The platform also includes a customizable customer portal, enabling users to manage their subscriptions independently. This reduces the support burden for SaaS companies. Additionally, Stripe automates revenue recognition and offers detailed financial reports, making it easier to track key metrics and streamline operations.
For example, Postmates partnered with Stripe to address involuntary churn, resulting in an added $63 million in revenue. Stripe's card account updater automatically refreshed over two million expired or replaced cards, recovering $60 million in revenue. Meanwhile, Smart Retries helped recover more than 200,000 failed payments, contributing an additional $3 million.
These features make Stripe a reliable choice for managing subscription-based revenue streams.

A standout feature is Transparent Redirect, which helps developers handle PCI compliance more easily. By sending payment details directly to PayPal's servers, this feature reduces the compliance burden.
Important Note: Website Payments Pro is no longer available to new users. Instead, they must use the Advanced Debit and Credit solution.
These integration options also provide the groundwork for seamless recurring billing capabilities.
Recurring Billing Support
For SaaS businesses with subscription models, PayPal Payments Pro supports recurring billing, enabling automatic payments for subscriptions or other scheduled charges. Developers can use the CreateRecurringPaymentsProfile API, which requires credit card details, billing information, and a start date. Once set up, PayPal handles payments automatically according to the schedule until the profile is canceled, expires, or hits the maximum number of allowed failures.

Final Thoughts
Picking the right payment API isn't just another item on your to-do list - it’s a cornerstone of scalable growth. A payment provider is more than a way to process transactions; the wrong choice can cost you customers, revenue, and valuable time. On the flip side, the right partner brings automation, reliability, and the flexibility to grow with your business.
For developers in the U.S., three factors should guide your decision: ease of integration, documentation quality, and transparent pricing.
Ease of Integration
When you’re building and iterating quickly, integration capabilities matter. Look for APIs with strong SDKs and clear error feedback. Stripe, for example, is well-regarded for its developer-friendly tools, which can save you significant time during implementation. Before committing, test integrations in a sandbox environment to catch potential issues early.
Quality Documentation
Good documentation can make your development process smoother, while bad documentation can slow you down. Stripe has set the bar high with its clean design, practical examples, and detailed guides. In fact, clear and thorough documentation can boost developer productivity by 55%. Focus on APIs that provide well-organized troubleshooting guides, detailed parameter descriptions, and clear authentication examples.
Transparent Pricing
As your business scales, pricing transparency becomes critical. Stripe’s core rate of 2.9% + $0.30 per transaction is straightforward, but additional features can push costs above 5%. Paddle, on the other hand, charges 5% + $0.50 but includes tax compliance and merchant-of-record services, which can be worth the higher cost for global operations. Knowing exactly what you’re paying for helps you manage expenses and avoid surprises.
Subscription management is another key area to prioritize if you rely on recurring revenue. With the growing adoption of digital wallets, ensure your API supports modern payment methods like Apple Pay and Google Pay, along with traditional credit cards. APIs that simplify subscription management can help you maintain steady revenue streams.
At the end of the day, choosing the right payment gateway - alongside a reliable SaaS billing system - isn’t just about processing payments. It’s about scaling your business, entering new markets, and keeping your customers happy. Take the time to evaluate your needs, test thoroughly, and think long-term. Your future self - and your customers - will appreciate the effort you put in now.
