SaaS payment processing

SaaS companies have very specific and unique needs when it comes to payment processing.

As many tend to run on a subscription model, payment processors need to be able to handle recurring billing. And if the company operates internationally, it’ll also need to offer multi-currency payments and global tax compliance.

Ideally, SaaS businesses need their payment processors to do three specific things:

1. Provide a payment gateway
2. Offer efficient subscription management
3. Give users a front-end interface to interact with their subscription.

It’s also critical to have processes that are as streamlined as possible, making use of automation tools to save time and reduce the risk of human error.

Below, we’ll take a look at SaaS payment systems that do most if not all of these things. This includes big names such as:

• Braintree
• ChargeBee
• Stripe
• GoCardless
• Worldpay
• Paddle.

Comparing SaaS payment processing services: criteria

When searching for the best SaaS payment gateways and processors, it’s tempting to focus solely on price. But while cost is important, there are other things you should be looking at.

Below, we’ll compare providers based on these key criteria:

• Essential features
• Cost (including monthly subscription costs and fees for add-ons)
• Integrations with other business tools and solutions.

It’s all to help you find a good fit for your business.

Braintree

Owned by payments giant PayPal, Braintree is aimed primarily at mobile users and offers both hosted and integrated payment gateway solutions.

Crucially for SaaS companies, it has subscription functionality.

Other key features include:

• Drop-in or customised user interface (UI)
• Recurring billing, including Account Updater tool
• Standard and advanced levels of fraud protection
• Huge choice of payment methods, including cards, PayPal, Apple Pay, Google Pay, Venmo and more.

Braintree can be integrated with lots of third-party apps and tools. This includes ecommerce platforms and billing applications, including WooCommerce, Salesforce, Recurly and Chargebee.

The platform has a per-transaction pricing model, where you’ll pay 1.9% + £0.20 for every payment and no monthly fees.¹

Braintree has a ‘Bad’ rating of 1.1 on Trustpilot, although it’s worth pointing out that this is from just over 200 reviews and the profile is unclaimed by the company.²

Chargebee

Chargebee is a US company which provides a payment platform specifically aimed at subscription businesses. This makes it ideal for SaaS companies, although it also serves utilities companies and other businesses which charge customers on a recurring basis.

Its main features include:

• Billing - managing subscriptions and invoicing at scale
• RevRec - automated, compliant revenue recognition
• Receivables - including tools to create a proactive collection strategy

• Performance - £499 a month up to £80,000 of cumulative billing, 0.75% above that
• Enterprise - custom pricing on request

An important thing to note is that Chargebee isn’t a payment gateway in itself. This means you’ll need to link it with another payment processor, which will mean you’ll have to pay its per-transaction fees too.

Chargebee has a ‘Average’ rating of 3.5 on Trustpilot, although it’s worth bearing in mind that this is only based on over 80 reviews.⁴

FAQs - SaaS payment processing

What is SaaS payment processing?

SaaS payment processing refers to the systems and services that enable Software as a Service (SaaS) companies to accept and manage payments from their customers. This often involves handling recurring subscriptions, one-time purchases, and various payment methods, ensuring a seamless experience for both the business and its users.

Why do SaaS businesses need specialized payment processing?

SaaS businesses often have unique billing models, such as recurring subscriptions, tiered pricing, and usage-based billing, which standard payment processors might not fully support. Specialized SaaS payment processors are built to handle these complexities, offering features like automated recurring billing, dunning management, and robust reporting tailored to subscription-based revenue.

What are the key features to look for in a SaaS payment processing provider?

When choosing a SaaS payment processing provider, look for features like recurring billing automation, support for multiple payment methods (credit cards, bank transfers, digital wallets), global payment capabilities, dunning management (for failed payments), robust reporting and analytics, and seamless integration with your existing CRM and accounting software. Security compliance (like PCI DSS) is also paramount.

How does a SaaS payment gateway differ from a traditional payment gateway?

While both facilitate online transactions, a SaaS payment gateway is specifically designed to handle the nuances of a subscription-based business model. It goes beyond simply authorizing transactions to include features like managing customer subscriptions, handling upgrades and downgrades, and automating recurring invoices, which are less common in traditional ecommerce gateways.

What security measures do SaaS payment processing providers implement?

Reputable SaaS payment processing providers adhere to strict security standards like PCI DSS compliance. They utilize advanced encryption, tokenization, and fraud detection systems (e.g., 3D Secure) to protect sensitive payment information and prevent fraudulent transactions. This helps safeguard both the business and its customers.

How can a good SaaS payment processor improve customer retention?

A robust SaaS payment processor contributes to customer retention by ensuring a smooth and reliable billing experience. Features like automated billing, clear communication about payments, and flexible payment options minimize payment-related issues, reduce churn due to failed transactions, and ultimately enhance overall customer satisfaction.
