What are SaaS Payment Rails?

SaaS決済レールとは、顧客、企業、銀行機関の間でお金を移動させる金融ネットワークです。これらには、ACH、RTP、FedNow、電信送金、SWIFT、SEPA、およびカードネットワークが含まれます。SaaS企業にとって、決済は事業の主要な部分であり、継続課金、国際顧客、自動化された金融ワークフローを処理する必要があるため、決済インフラストラクチャは極めて重要です。決済レールの選択は、顧客体験と業務効率の両方に影響を与える可能性があります。

SaaS payment rails differ from the e-commerce ones because in e-commerce, it’s mostly about purchasing items a single time, while for SaaS, it’s about subscription payments, renewals, and maintaining accounts over time. It’s mainly the subscription-based billing method that makes the difference.

Moreover, B2B SaaS and B2C SaaS have completely different demands. For example, a consumer subscription platform will prioritize convenience and payment methods. On the other hand, B2B software companies will generally be keen on checking lower fees, invoice payments, and bank-based transfers.

Some special attributes of SaaS payment rails are:

• Handle recurring billing and automated payments
• They are connected to billing and accounting systems
• Transaction speeds and settlement times may fluctuate
• Different payment methods have different fee structures
• The platform incorporates functionality for processing domestic and international transactions

There are several rails to choose from, and the optimal one can depend heavily on the specific use case. No single rail can be the best all-around solution for every type of transaction.

• ACH transfers are done through banks and are therefore most suitable for subscription-based recurring payments with B2B SaaS. Transaction fees are often lower than card fees and can affect expired customer accounts and involuntary churn, given the relative consistency of bank account information. 
• RTP and FedNow are real-time payment systems that facilitate rapid fund transfers. They can be utilized by SaaS companies for emergency payment processing, replenishing accounts, or enabling faster customer transactions. The presence of “Open Banking” tools may correlate with reduced customer friction through account verification features.
• Wire payments can be used for business transactions that involve high value or have time constraints. Wire transfers offer accessibility, but their cost could present an issue for small, regular subscription fees.
• SWIFT is mainly for international bank transactions between countries, whereas SEPA is about euro payments. These payment systems are used by SaaS companies to process cross-border subscriptions and pay vendors.
• Credit and debit cards are frequently used payment methods for SaaS onboarding and B2C subscriptions, due in part to customer preference for convenience and relatively fast approval processes. These cards are usable, but transaction fees generally apply, and card loss or expiration can correlate with customer churn.

Choosing​‍​‌‍​‍‌​‍​‌‍​‍‌ a payment rail impacts a lot more than just the way payments are processed. It has the potential to influence revenue streams, customer sentiment, and financial strategies.

• コスト: Transaction fees change in profit margins. Card payments typically have different fee structures than bank transfers, and percentage-based charges may correlate with fluctuations in recurring revenue with increased transaction volumes.
• Speed: Settlement timing impacts cash flow. Faster rails are correlated with changes in liquidity and waiting periods.
• セキュリティ: Different rails involve varying fraud protections and verification methods. Secure payment systems are associated with changes in operational risk and chargeback exposure.
• グローバルなリーチ: International SaaS businesses often require payment systems that support multiple countries and currencies.

Deciding on the right payment infrastructure can be a complex process. However, map out how money actually moves in your business to identify the payment rails that fit your client payment habits.

• Compare the costs of processing fees and the time taken to settle
• Give priority to integrations with billing systems
• If it is possible, use more than one payment method to reduce failures
• Look at the international payment needs early on

In particular:

• Volume of transactions and payment frequency
• Customer location and currency preferences
• Level of integration complexity and availability of technical support

多くのSaaS企業は、一般的に単一の決済方法に依存することを避けています。実際、複数の決済システムを組み合わせたマルチレール戦略を採用しています。このマルチレールアプローチにより、企業はコスト、速度、地域などの要素を考慮して決済システムを選択できます。ACHは定期的な請求書に適している一方、リアルタイム決済は緊急の取引に利用されることがあります。企業の事業展開は、課題発生時の決済オプションと関連し、ネットワーク遅延が発生した場合に備えて代替オプションを維持することがあります。
