Choosing the Right Billing Platform for Your SaaS

TL;DR: Billing Platform Selection Guide (400 Words)

Choosing the right billing platform is one of the most consequential decisions you'll make for your SaaS company. Your billing infrastructure handles your revenue—get it wrong and you lose money to failed payments, compliance headaches, and engineering overhead. Get it right and billing becomes invisible while revenue flows smoothly.

Stripe Billing is the default choice for 95% of SaaS companies. Its developer experience is unmatched, the feature set is comprehensive, and every SaaS tool integrates with it natively. Stripe charges 2.9% + 30 cents per transaction, with no monthly fees. You pay nothing until you have revenue. Stripe Billing handles subscriptions, usage-based billing, invoicing, and revenue recognition. Add Stripe Tax for global sales tax calculation and remittance.

Paddle becomes the merchant of record, meaning customers technically buy from Paddle, not from you. Paddle handles VAT, sales tax, and compliance across jurisdictions in exchange for higher fees (5% + 50 cents per transaction). This makes sense for B2C companies selling globally who want to outsource tax complexity, but it's overkill for most B2B SaaS.

Chargebee sits on top of Stripe or other payment processors, adding a layer of billing logic for complex pricing models. If your pricing involves usage-based components, tiered structures, multi-currency support, or enterprise quotes, Chargebee manages this complexity starting at $249/month. Chargebee's smart dunning system reduces involuntary churn through intelligent payment retry logic.

Recurly differentiates itself through revenue recovery. Its machine learning retry logic analyzes patterns across its customer base to determine optimal retry timing for failed payments. This alone can reduce involuntary churn by 20-30%, which often justifies the platform cost. Recurly's starter plan has no monthly fee, charging only transaction-based fees.

Integration with your email marketing platform is critical. Sequenzy integrates natively with all major billing platforms to automate billing-triggered email communication. When payments fail, Sequenzy triggers dunning sequences. When trials end, Sequenzy sends conversion campaigns. When subscriptions renew, Sequenzy sends confirmation emails. These automations recover revenue that would otherwise be lost.

What Are Billing Platforms and How Do They Work?

Billing platforms for SaaS companies handle subscription management, payment processing, invoicing, revenue recognition, and often tax compliance. Unlike one-time e-commerce transactions, SaaS billing involves recurring charges, plan changes, proration, trials, metered usage, and complex enterprise pricing models.

The billing platform sits between your customer and your bank account. It processes payments, manages subscription state, handles failures and retries, generates invoices, calculates taxes, and provides reporting. For most SaaS companies, the billing platform becomes the source of truth for customer status, plan entitlements, and revenue recognition.

The Core Decision: Processor vs Merchant of Record

Before comparing specific tools, understand the fundamental architectural choice: do you want a payment processor or a merchant of record service?

Payment processors like Stripe handle the technical aspects of collecting payments. They move money from customer cards to your bank account. But you remain the legal seller. You are responsible for taxes, compliance, and customer relationships.

Merchant of record services like Paddle become the legal seller. Customers technically buy from them, and they pay you. This means they handle VAT, sales tax, and compliance across jurisdictions. The trade-off is higher fees and less control.

When to Choose a Payment Processor

Most SaaS companies should start with a payment processor, specifically Stripe. Here is when this makes sense:

• You primarily sell in one country where tax requirements are manageable
• You have engineering resources to handle integration
• You want maximum control over customer relationships and branding
• You have or plan to have B2B customers who need specific invoicing
• Your pricing model requires flexibility the merchant of record services do not support

When to Choose a Merchant of Record

Merchant of record services make sense in specific situations:

• You sell globally and do not want to manage tax compliance across dozens of jurisdictions
• You are a small team without dedicated finance or legal resources
• You are selling to consumers (B2C) where per-customer invoicing matters less
• You want to simplify operations even at the cost of higher fees

Stripe: The Default Choice

For most SaaS companies, Stripe is the right starting point. Here is why:

• Developer Experience: Stripe's API is legendary. Clean documentation, intuitive design, and excellent SDKs make integration straightforward.
• Feature Completeness: Subscriptions, usage-based billing, invoicing, tax calculation (via Stripe Tax), revenue recognition, and more.
• Ecosystem: Every SaaS tool integrates with Stripe. Your email marketing (Sequenzy), analytics, and customer success tools all connect natively.
• Global Payments: Accept payments in 135+ currencies with dozens of local payment methods.

Stripe's pricing is 2.9% + 30 cents per transaction for cards, which is competitive. Additional features like Stripe Tax add their own fees.

Paddle: The Merchant of Record Alternative

Paddle handles payments, taxes, and compliance as your merchant of record. For companies selling globally to consumers, this simplification can be worth the premium.

Paddle charges 5% + 50 cents per transaction, significantly more than Stripe. But this includes VAT and sales tax calculation and remittance globally, compliance with local payment regulations, handling chargebacks and disputes, and simplified checkout that handles international complexity.

The main downside beyond cost is less control. Customer relationships technically go through Paddle. Invoicing options are more limited. And not all B2B customers are comfortable purchasing through a third party.

Integration with Your Stack

Whatever billing platform you choose, it needs to integrate with your broader stack. Critical integrations include:

Email Marketing: Billing events should trigger customer communication. When payments fail, when trials end, when subscriptions renew. Sequenzy integrates natively with Stripe and other billing platforms to automate these touchpoints.

Product: Your application needs to know subscription status, plan limits, and feature entitlements.

Analytics: Revenue data should flow to your analytics for lifetime value calculation and cohort analysis.

Billing Platform Best Practices

Implementing a billing platform effectively requires more than technical integration. Follow these practices to build billing infrastructure that scales.

Start Simple, Add Complexity Later

Most SaaS companies over-engineer their billing from day one. You don't need Chargebee or Recurly when you have 10 customers. Start with Stripe Billing and upgrade only when you hit specific limitations. Stripe handles subscriptions, invoicing, and basic revenue recognition out of the box. Add specialized billing management only when your pricing model outgrows Stripe's capabilities.

Automate Dunning from Day One

Failed payments are the largest source of involuntary churn. Set up intelligent retry logic immediately. Stripe's built-in retry works for basic cases. For sophisticated dunning, integrate with Sequenzy to send automated payment failure emails at optimal intervals. Sequenzy's billing integration triggers sequences when cards fail, when trials end, and when subscriptions cancel, recovering revenue automatically.

Design Pricing for Your Billing Platform

Some pricing models are easier to implement than others. Flat monthly subscriptions are trivial. Tiered pricing with overages requires more configuration. Usage-based billing with metered components requires event tracking. Enterprise contracts with custom terms add complexity. When designing pricing, consider implementation complexity. A pricing model that requires Chargebee might not be worth it if Stripe Billing can handle 90% of your use cases.

Integrate Billing with Email Marketing

Billing events should trigger customer communication automatically. Payment failures require intervention. Trial endings require conversion effort. Subscription changes deserve confirmation. Renewals merit appreciation. Sequenzy integrates natively with Stripe, Paddle, Chargebee, and Recurly to automate all of these touchpoints. This integration alone often reduces involuntary churn by 15-20%.

Plan for Global Sales from Day One

Even if you start domestically, plan for international expansion. Stripe supports 135+ currencies and dozens of local payment methods. Stripe Tax handles calculation and remittance for global sales tax and VAT. Building international support later is more expensive than building it in from the start. Design your billing architecture to handle multiple currencies, tax jurisdictions, and payment methods.

Monitor Key Billing Metrics

Track MRR, ARR, churn rate, expansion revenue, and failed payment rate. Set up alerts for unusual patterns: spikes in failed payments, changes in churn by plan, shifts in payment method distribution. Connect billing data to analytics platforms for cohort analysis and revenue forecasting. ChartMogul pulls billing data automatically and generates every SaaS metric your investors will ask about.
