Best payments stack for global SaaS subscriptions?

For a global SaaS subscription business, I’d choose the stack based mainly on whether you want to own the tax/compliance layer or outsource it.

My practical shortlist

If I were designing it today

For a startup/scale-up:

Paddle → your SaaS → accounting/ERP

Paddle is a Merchant of Record, so it handles payments, subscription billing, sales tax/VAT/GST, fraud and compliance. It currently advertises support across 300+ markets and 100+ tax jurisdictions.

That is particularly attractive if your biggest concern is "I want customers anywhere without building a tax department."

For a larger SaaS where payments are strategically important:

Stripe Billing + Stripe Tax + Stripe Radar → accounting/ERP

Stripe supports 100+ payment methods and 135+ currencies, with Billing handling subscriptions and automated revenue-recovery features. Stripe Tax covers sales tax/VAT/GST in 90+ countries.

I'd favor this architecture when you want maximum control over checkout, pricing, payment methods, customer data, and payment economics.

For enterprise/global optimization:

Chargebee + multiple PSPs (Stripe + Adyen, for example)

Chargebee can sit above multiple payment processors: it advertises 40+ gateways, 50+ payment methods and 150+ countries, with routing capabilities that reduce dependence on a single gateway.

Adyen is particularly interesting once payment optimization becomes material: it supports 200+ payment methods and 150+ currencies for its subscription offering.

The key architectural decision

I'd actually make Merchant of Record vs. Merchant of Record not the first decision:

• Want minimum operational burden: Paddle.
• Want maximum control and flexibility: Stripe Billing + Stripe Tax.
• Need sophisticated billing plus payment orchestration: Chargebee + multiple PSPs.
• Already doing significant global enterprise volume: consider Adyen as a primary/secondary processor.

One important distinction: Chargebee is not equivalent to Paddle's MoR model. Chargebee can automate tax calculation and connect to tax/payment infrastructure, but your company still has substantially more responsibility for the underlying tax/compliance architecture.

If you tell me your ARR, average subscription price, B2B vs B2C, countries you sell into, and whether you're usage-based or fixed-price, I can map out the exact stack I'd use—including Stripe vs Paddle economics, tax, invoicing, dunning, local payment methods, and accounting/reconciliation.

Paddle → your SaaS → accounting/ERP

Paddle is a Merchant of Record, so it handles payments, subscription billing, sales tax/VAT/GST, fraud and compliance. It currently advertises support across 300+ markets and 100+ tax jurisdictions.

That is particularly attractive if your biggest concern is "I want customers anywhere without building a tax department."

For a larger SaaS where payments are strategically important:

Stripe Billing + Stripe Tax + Stripe Radar → accounting/ERP

Stripe supports 100+ payment methods and 135+ currencies, with Billing handling subscriptions and automated revenue-recovery features. Stripe Tax covers sales tax/VAT/GST in 90+ countries.

I'd favor this architecture when you want maximum control over checkout, pricing, payment methods, customer data, and payment economics.

For enterprise/global optimization:

Chargebee + multiple PSPs (Stripe + Adyen, for example)

Chargebee can sit above multiple payment processors: it advertises 40+ gateways, 50+ payment methods and 150+ countries, with routing capabilities that reduce dependence on a single gateway.

Building the best payments stack for a global SaaS subscription business comes down to one core architectural choice: Do you want to act as the Merchant of Record (MoR), or do you want to use a modular payment processor/billing engine?

The optimal stack depends heavily on your company stage, engineering capacity, and how much global tax liability you want to shoulder.

Option 1: The "Zero Headache" Stack (Merchant of Record)

Best for: Early to mid-stage SaaS ($0 to $5M ARR), solo founders, or lean teams that want to sell globally on day one without dealing with international tax compliance, VAT/GST collection, or local entity setups.

• The Engine / MoR: Paddle or Lemon Squeezy
• How it works: They act legally as the reseller of your software. Your customer buys from them, and they handle global sales tax, VAT, GST, fraud prevention, chargebacks, and localized payment methods across 180+ countries. You receive a clean payout.
• Pros: Complete offloading of tax compliance liability; incredibly fast global expansion; built-in checkout UI.
• Cons: Higher per-transaction fees (around 5% + $0.50); less granular control over the raw payment routing layer.

Option 2: The Developer-First / Native Stack

Best for: Seed to scale-up SaaS with dedicated engineering resources who want deep customization, usage-based/metered billing, and direct merchant control.

• The Processor & Billing Layer: Stripe (Stripe Billing + Stripe Radar)
• Add-on for Tax (Crucial for Global): Stripe Tax or Anrok / TaxJar
• How it works: Stripe handles the raw credit card processing, subscription life cycles, and localized pricing, while Stripe Tax automatically calculates and tracks global tax thresholds.
• Pros: Unmatched developer documentation and API flexibility; highly modular; excellent native support for usage-based/metered billing.
• Cons: You are still legally the merchant, meaning you are responsible for monitoring and registering for global tax nexus, managing complex dunning (failed payment recovery), and handling localized compliance.

Option 3: The Enterprise / Multi-Gateway RevOps Stack

Best for: High-growth or enterprise SaaS ($5M+ ARR) looking to optimize authorization rates, eliminate single-processor dependency, and tie in complex finance workflows.

• The Subscription/Billing Layer: Chargebee or Recurly
• The Underlying Processors: Stripe + Adyen (routed dynamically)
• How it works: Chargebee/Recurly sits on top as the revenue operations and subscription brain, letting you orchestrate multiple payment gateways underneath to maximize successful payments and failover routing.
• Pros: Advanced dunning management (recovering failed payments), deep ERP/accounting integrations, and multi-gateway redundancy.
• Cons: Expensive base subscription fees; multi-layered setup requiring tight coordination between engineering and finance teams.

To help narrow down the ideal stack for your product, could you share:

• Your current or projected ARR range
• Your primary pricing model (flat-rate monthly/annual vs. usage-based/metered)
• Where your target audience is geographically located (US-centric vs. heavily international/EU)

For a global SaaS subscription business, I’d choose based on how much payments/tax infrastructure you want to own.

My default recommendation: Stripe + Stripe Billing

Stripe is the best all-around choice if you expect to build a sophisticated SaaS business rather than outsource the entire payments function.

• Stripe Billing — subscriptions, usage-based billing, prorations, trials, coupons, invoices, customer portal.
• Stripe Payments — cards + 100+ payment methods, 135+ currencies, localized payment experiences.
• Stripe Tax — automated sales-tax/VAT/GST calculation across 90+ countries.
• Stripe Radar — fraud prevention.
• Your own application remains the source of truth for entitlements, plans, usage, and customer state.

Stack:

Your app → Stripe Checkout/Payment Element → Stripe Billing → Stripe Tax → Stripe Radar → your DB/webhooks

This is what I'd pick for most VC-backed or technically sophisticated SaaS companies.

If you want maximum simplicity: Paddle

Paddle is particularly compelling for an early-stage SaaS selling internationally.

Paddle is a Merchant of Record, meaning it handles payment processing, subscription billing, tax collection/compliance, fraud and related responsibilities rather than leaving you to assemble those pieces. It supports recurring billing across 300+ markets.

Stack:

Your app → Paddle → customer

I'd strongly consider Paddle if you have a small finance/legal team and don't want to deal with global VAT/GST/sales-tax registrations and remittance yourself.

The tradeoff is less control and potentially higher economics than operating your own payment stack.

If you're already large: Chargebee + multiple PSPs

Chargebee becomes interesting when payment optimization itself becomes a major revenue lever.

Chargebee can sit above multiple payment processors, with 40+ gateway integrations and smart routing based on things like currency, payment method, geography and other transaction context.

A sophisticated stack might be:

Your app → Chargebee → Stripe / Adyen / Checkout.com / local PSPs

This gives you PSP redundancy and routing optimization, which can matter considerably at high volume.

Where Adyen fits

Adyen is my choice when you're operating at significant scale and want deep control over global acquiring/payment optimization.

Adyen offers 200+ payment methods and 150+ currencies, and is designed around optimizing recurring payments and authorization across markets.

I'd generally not start a new SaaS with Adyen unless you have a specific reason. Stripe is usually faster to launch.

My ranking

One important architectural point: don't make Stripe/Paddle your application's subscription state. Keep your own customer → subscription → entitlement model and use provider webhooks as the payment-system events. That makes migration between Stripe/Paddle/Adyen dramatically less painful.

If you tell me your ARPU, expected ARR, B2B vs B2C, countries, and whether you're usage-based, I can recommend the exact stack and estimate the all-in payment/tax cost for each option.

For global SaaS subscriptions, the "best" payment stack depends heavily on your stage, engineering capacity , and appetite for tax compliance . Global scale introduces multi-currency pricing, localized payment methods (like iDEAL, SEPA, or Pix), and the nightmare of international sales tax/VAT compliance.

The top global SaaS payment stacks fall into three distinct architectures:

• The Merchant of Record (MoR) Stack (Best for early-stage to $1M ARR / Solopreneurs)
• The Modern All-in-One Engine (Best for growth-stage / scaling B2B SaaS)
• The Enterprise Composite Stack (Best for high-volume / complex usage-based pricing)

1. The Merchant of Record (MoR) Stack

Ideal if you want to completely outsource global sales tax, VAT, fraud liability, and compliance.

• The Provider: Paddle or Lemon Squeezy
• How it works: They don't just process your payments; they act as the legal reseller of your software. When a customer in Germany buys your SaaS, they are technically buying it from Paddle/Lemon Squeezy, and Paddle remits the VAT.
• Pros: Zero global tax nexus headaches, built-in dunning/localization, and simplified compliance.
• Cons: Higher flat percentage fees (usually around 5% + $0.50 per transaction), and your customer sees Paddle on their bank statement instead of your brand name.

Stripe is the gold standard for developer experience. Their API is poetry, and Stripe Billing is the most robust subscription engine on the planet. But for micro-SaaS, the “standard” 2.9% + 30¢ fee is a lie.

2. The Modern All-in-One Engine (Stripe Ecosystem)

Ideal if you want complete brand control and have basic-to-moderate dev resources.

• The Stack: Stripe + Stripe Billing + Stripe Tax
• How it works: You use Stripe as your direct payment processor and turn on their native modules for recurring billing, automated dunning (smart retries), and global tax calculation.
• Pros: Unmatched developer documentation, seamless UI integration, high authorization rates globally, and modular tools that scale from $0 to enterprise.
• Cons: You are responsible for global tax compliance (you have to monitor thresholds and register/file in states/countries via Stripe Tax or manual oversight), and cross-border currency conversion fees add up.

3. The Enterprise Composite Stack

Ideal for scaling or usage-based B2B SaaS with high volume ($2M+ ARR).

• The Stack: Adyen or Checkout.com + Chargebee or Recurly
• How it works: A specialized recurring billing layer (Chargebee/Recurly) sits on top of an enterprise-grade global payment gateway (Adyen/Checkout.com) to optimize local acquiring banks and reduce failed payments.
• Pros: Lowest interchange fees at scale, robust multi-gateway failover (if one processor goes down, it flips to another), and advanced revenue recovery/retention analytics.
• Cons: Complex, multi-vendor setup requiring dedicated engineering or finance operations oversight.

To help narrow down the ideal recommendation, tell me:

• What is your current or projected ARR?
• Are you using flat-tier subscriptions or a usage-based/metered model?
• Do you have an in-house developer to maintain the integration?

For a global SaaS subscription business, my default recommendation in 2026 is:

Best overall: Stripe Billing + Stripe Tax

stripe.com is the best fit if you want maximum control, a strong developer ecosystem, and the ability to optimize payments yourself. Stripe supports 100+ payment methods, 135+ currencies, localized checkout, recurring billing, and tax tooling across 90+ countries.

A good stack would be:

• Payments: Stripe Payments
• Subscriptions: Stripe Billing
• Tax: Stripe Tax
• Fraud: Stripe Radar
• Checkout: Stripe Checkout or Elements
• Revenue recovery: Stripe's automated recovery tools
• Accounting: Stripe → your accounting/ERP
• Analytics: your warehouse + Stripe webhooks/events

Best if you want to avoid global tax/compliance: Paddle

paddle.com is compelling if your priority is "I want to sell worldwide without building a payments/tax operation."

Paddle is the Merchant of Record, so it handles payment processing, subscription billing, sales tax/VAT/GST collection and remittance, fraud, and related compliance. It says it supports recurring billing across 300+ markets and handles tax obligations in 100+ jurisdictions.

That's particularly attractive for a small/medium SaaS company where finance/legal engineering time is expensive.

Best for very large/global enterprise: Adyen

adyen.com becomes more interesting when you're doing large transaction volumes, many countries, and sophisticated payment optimization.

Adyen offers 200+ payment methods, 150+ currencies, local acquiring, and intelligent routing for recurring payments.

The tradeoff is that you generally have to build/operate more of the billing and tax architecture around it than with Paddle.

My decision rule

If I were building a new global SaaS today: I'd start with Stripe Billing + Stripe Tax, unless minimizing tax/compliance operations was more important than payment/billing flexibility—in which case I'd choose Paddle.

One important architectural point: don't make your application depend directly on the payment provider's customer/subscription objects. Keep your own canonical customer, subscription, entitlement, and invoice models, and treat Stripe/Paddle webhooks as the payment-system events that synchronize them. That makes a future Stripe → Adyen/Paddle migration dramatically less painful.

Choosing the best payments stack for global SaaS subscriptions depends heavily on your stage of growth, engineering bandwidth , and geographic footprint . Global compliance (VAT/GST), local payment methods, multi-currency pricing, and dunning management add layers of complexity that a simple Stripe integration handles well early on, but often require specialized orchestration or Merchant of Record (MoR) setups at scale.

The top configurations are categorized below by business stage and model:

1. The "Zero-Ops" Fast-Track: Merchant of Record (MoR)

Best for: Early-stage startups, bootstrapped founders, and indie hackers who want to launch globally on day one without hiring a tax attorney or setting up foreign entities.

• The Stack: Paddle or Lemon Squeezy (or FastSpring for enterprise-leaning digital goods).
• How it works: They don't just process payments—they resell your software. They become the Merchant of Record, meaning they legally take on global sales tax, VAT, GST collection and remittance, fraud liability, and compliance worldwide.
• Pros: Instant global tax compliance in 100+ countries, built-in localized checkouts, and zero headache with chargebacks or local acquiring.
• Cons: Higher take-rate/fees (usually around 5% + fixed fee), less brand control over the exact checkout, and payouts are handled via their payout schedule.

2. The Gold Standard: The "All-in-One" Developer Stack

Best for: Seed to Series B SaaS companies with developer resources that want complete control over the user experience and pricing logic.

• The Stack: Stripe (Stripe Billing + Stripe Checkout/Elements + Stripe Tax).
• How it works: Stripe handles everything from the front-end payment elements and multi-currency pricing tables to advanced subscription mechanics (usage-based billing, seat-based tiering, proration) and automated dunning.
• Pros: Unmatched API flexibility, native support for 135+ currencies, smart localization, and an enormous ecosystem of pre-built integrations. Adding Stripe Tax minimizes cross-border tax calculation burdens.
• Cons: You are still the Merchant of Record—meaning you are responsible for managing economic nexus, tax registration, and handling local failed-payment drops if your authorization rates dip in specific regions.

3. The Enterprise & High-Volume Orchestration Stack

Best for: Scaling or enterprise SaaS ($5M+ ARR) looking to optimize authorization rates, reduce processor fees, and prevent single-vendor lock-in.

• The Stack: Chargebee or Maxio (Subscription Management & Billing Engine) + Adyen / Stripe / GoCardless (Multi-Gateway Layer).
• How it works: Decouples your billing/catalog logic from the actual credit card processors. You use a billing orchestrator like Chargebee to handle complex contracts, invoicing, and revenue recognition (GAAP/ASC 606), while dynamically routing transactions through regional gateways (like Adyen in Europe or local acquirers) to maximize successful payments.
• Pros: Processor independence, lower blended processing fees at high volume, superior local acquiring rates in international markets, and deep revenue management/metrics.
• Cons: High implementation overhead, multiple vendor contracts to manage, and complex initial engineering configuration.

Community Perspectives

When building a global stack, developers and founders frequently weigh the administrative nightmare of taxes versus the flexibility of owning the infrastructure:

I switched to a Merchant of Record early on because dealing with international VAT rules and global tax collection was eating up all my development time. It's expensive fee-wise, but worth the peace of mind.

Stripe Billing is unmatched if you have custom usage-based or hybrid seat pricing. Once you turn on Stripe Tax, it bridges a lot of the global compliance gap without forcing you into an MoR setup.

To help narrow down the ideal architecture for you, tell me:

• What is your current or projected ARR?
• Are you selling primarily B2B, B2C, or a mix?
• Do you need usage-based / metered billing or standard flat/tiered seats?

The best overall payments stack for global SaaS subscriptions is Stripe Billing + Stripe Payments + Stripe Tax for product-led growth (PLG) or a Merchant of Record (MoR) like Paddle if you want to completely outsource global tax compliance, VAT collection, and liability.

For a truly global SaaS business, your choice depends heavily on your company stage, engineering resources, and how much you want to handle international tax compliance yourself.

Core Payment Stack Options by SaaS Stage

Key Components of a Global Stack

• Payment Processor / Gateway (PSP): Captures the money via global credit cards, local wallets (Alipay, WeChat Pay), and regional schemes. Stripe or Adyen lead here.
• Subscription & Billing Engine: Handles proration, trials, seat-based scaling, invoicing, and dunning (failed payment recovery). Handled natively via Stripe Billing or dedicated layers like Chargebee or Recurly.
• Tax Compliance Layer: Calculates, collects, and remits global sales tax, VAT, and GST. Handled automatically if you use a Merchant of Record (MoR) like Paddle, or via Stripe Tax.

If you share your expected monthly recurring revenue (MRR), primary customer locations (B2B vs B2C) , and pricing model (flat vs usage-based) , I can recommend the exact stack components you need.

For a global SaaS subscription business, the best payments stack is usually not just a payment processor — it is a combination of:

1. Payment acceptance
2. Subscription billing
3. Tax/compliance handling
4. Revenue operations
5. Fraud + payment recovery

The “best” stack depends heavily on your stage and pricing model. The common choices are Stripe, Paddle, and Chargebee, but they solve different problems.

My default recommendations

Dezen Technology Chargebee## Stack option 1: The “startup default”

Stripe

• Stripe Payments
• Stripe Billing
• Stripe Tax
• Stripe Radar
• Your own entitlement service

Best when:

• You want maximum control
• You have engineers
• Pricing is relatively simple

Example architecture:

Customer
   |
Stripe Checkout
   |
Stripe Billing
   |
Webhooks
   |
Your Billing Service
   |
Entitlements / Product Access

Pros:

• Excellent APIs
• Huge ecosystem
• Flexible checkout
• Easy experimentation

Cons:

• You remain responsible for much of the tax/compliance burden unless you use additional services.

---

Stack option 2: The “sell globally without tax headaches” stack

Paddle

Paddle acts as a Merchant of Record (MoR) — meaning it becomes the seller handling many tax and compliance obligations rather than you doing it directly.

Architecture:

Customer
   |
Paddle Checkout
   |
Paddle Billing
   |
Your App
   |
Entitlements

Best for:

• Indie SaaS
• Small teams
• Global B2C/self-serve SaaS
• Selling into many countries early

Trade-off:

• Higher fees
• Less control over some billing flows

---

Stack option 3: The “serious B2B SaaS” stack

Chargebee + payment gateway

Typical setup:

Customer
   |
Your App
   |
Chargebee
   |
Stripe / Adyen / Checkout.com
   |
Banks

Best for:

• Multiple plans
• Annual contracts
• Sales-assisted deals
• Coupons/promotions
• Complex invoicing
• Revenue operations

Chargebee is especially useful when billing becomes a business process involving finance, sales, and customer success.

Things I would build yourself (even if using a provider)

Do not make Stripe/Paddle/Chargebee your source of truth.

Keep your own:

• Customer table
• Subscription state
• Entitlements
• Invoice history
• Payment event log
• Revenue analytics model

Your payment provider should be the system of record for money movement, not your entire product database.

---

My short answer

For most global SaaS startups today:

• Default choice: Stripe Billing
• If you hate tax/compliance: Paddle
• If you have complex B2B billing: Chargebee + Stripe
• If you are building AI/usage pricing: Stripe or Chargebee with a proper metering layer

The biggest mistake is choosing based only on transaction fees. The expensive part of SaaS billing is usually operational complexity, failed payments, tax compliance, and migrations later.

My short answer

For most global SaaS startups today:

Building a global payments stack for SaaS subscriptions means solving three distinct challenges: recurring billing logic (trials, upgrades, prorations), global acquiring and payment methods (local cards, SEPA, ACH, iDEAL), and indirect tax/compliance (VAT, GST, sales tax).

Depending on your engineering resources and scale, the modern landscape offers a few battle-tested architectural patterns.

Phase 1: The Modern Stack Archetypes

1. The Lean & Fast Route: Stripe + Stripe Billing

Best for early-to-mid stage SaaS looking for rapid implementation with minimal overhead.

• The Setup: Stripe handles both the gateway/processing layer and the subscription lifecycle logic via Stripe Billing.
• Why it works: It natively supports 135+ currencies, smart retries, localized payment methods, and automated dunning.
• The Catch: As you scale globally, international card authorization rates can dip compared to local acquirers, and you are still on the hook for managing global tax compliance (though tools like Stripe Tax help bridge the gap).

2. The Scale-Up Standard: Dedicated Billing Engine + Multi-Processor Gateway

Best for growing SaaS companies that need robust revenue recovery, multi-currency optimization, and zero vendor lock-in.

• The Setup: A subscription management layer like Chargebee or Recurly sitting on top of enterprise processors like Adyen, Checkout.com , or Braintree.
• Why it works: Dedicated billing engines offer superior dunning, complex entitlements management, and multi-gateway routing (if one processor goes down or fails an authorization, it smartly reroutes). Adyen or Checkout.com provide high local-acquiring authorization rates across Europe, APAC, and Latin America.

3. The Hands-Off Compliance Route: Merchant of Record (MoR)

Best for global-first software and SaaS companies that want to completely outsource tax collection, liability, fraud, and local compliance.

• The Setup: Paddle, Lemon Squeezy, or PayPro Global.
• Why it works: Technically, the MoR resells your software globally. They become the entity-of-record on the transaction, meaning they assume responsibility for global sales tax, VAT, compliance, and chargebacks. You just get a clean payout.
• The Catch: You lose some granular control over the checkout experience and customer data relationship, and their take-rates/fees are typically higher than a direct processor stack.

Core Components Checklist

1. Subscription & Dunning Management: Essential for automated retries on expired or failed cards. Look for tools that feature customizable smart-retries and pre-dunning email triggers to minimize involuntary churn.
2. Local Payment Method (LPM) Support: Credit cards aren't king everywhere. Ensure your stack supports regional preferences—like SEPA Direct Debit in the EU, iDEAL in the Netherlands, Pix in Brazil, or ACH/RTP in the US.
3. Tax Automation Layer: If you aren't using an MoR, pair your stack with dedicated compliance software like Anrok, TaxJar, or Avalara to handle economic nexus tracking and invoice generation worldwide.

To help narrow down the ideal architecture for you, tell me:

• What is your estimated Monthly Recurring Revenue (MRR) or transaction volume?
• What percentage of your customers are international vs. domestic?
• Do you have the engineering capacity to maintain custom billing logic, or do you prefer a fully managed solution?

For a global SaaS subscription business, the best payments stack is usually not a single provider. The right stack depends on whether you want maximum control + lower fees or outsourced global compliance.

Recommended default stack (most SaaS companies)

1. Payments + subscriptions

Stripe

• Stripe Payments → cards, wallets, local payment methods
• Stripe Billing → recurring subscriptions, trials, proration, upgrades/downgrades, usage billing
• Stripe Customer Portal → self-service subscription management
• Stripe Radar → fraud controls

Best fit:

• B2B SaaS
• Developer-led companies
• Companies expecting custom pricing models
• Teams that can handle tax/compliance work

Tradeoff:

• You remain the merchant of record, so VAT/GST/sales tax obligations are your responsibility unless you add services like Stripe Tax.

---

2. Merchant of Record layer (if you want global simplicity)

Paddle or similar MoR providers

Use this if you sell globally and do not want to manage:

• VAT/GST registration
• tax collection/remittance
• invoicing rules
• some compliance obligations

Tradeoff:

• Higher take rate, but you are buying operational simplicity.

---

3. Enterprise payments

Add:

• Adyen for large-scale international acquiring
• ACH/wire transfers for enterprise contracts
• Net-30/Net-60 invoicing

Adyen tends to make more sense when payment optimization and local acquiring become a major revenue lever rather than when you are just launching.

My picks by stage

Don't forget the "boring" pieces

A mature SaaS payments stack also needs:

• Dunning/revenue recovery

• failed payment retries

• card updater

• cancellation flows

• Subscription data model

• product catalog

• entitlements

• usage metering

• billing events

• Finance

• revenue recognition

• invoice exports

• reconciliation

• Backup payment rails

• secondary processor

• bank transfer option for large customers

---

If I were building a new global B2B SaaS today, I would typically start with:

Stripe Billing + Stripe Payments + Stripe Tax + Chargebee/Orb/Metronome (only if pricing complexity requires it) + ACH invoicing for enterprise.

I would switch to or add a Merchant of Record model when international tax operations become a distraction rather than a competitive advantage.
