Stripe processes over $1 trillion in payments annually. But if you’re using it to sell SaaS globally, there’s a cost Stripe’s pricing page doesn’t mention: the hidden compliance tax you’re paying with your own time and money.
There are two fundamentally different ways to handle payments for your SaaS: a payment processor (like Stripe, Braintree, or PayPal) and a merchant of record (like Fungies.io, Paddle, or FastSpring). They’re not interchangeable. One handles money movement. The other handles money movement and the legal, tax, and compliance burden that comes with it.
This guide breaks down exactly what each does, what it costs you (really), and which one your SaaS actually needs right now.
What Is a Payment Processor?
A payment processor does one thing: it moves money from your customer’s bank account to yours. That’s it.
Stripe, the most popular example, gives you APIs to build checkout flows, accept credit cards, manage subscriptions, and receive payouts. It’s developer-friendly, well-documented, and genuinely excellent at what it does. The base rate is 2.9% + $0.30 per transaction for US cards.
But here’s what a payment processor doesn’t do:
- Register for VAT, GST, or sales tax on your behalf
- Calculate and collect the right tax rate for each country/state
- File tax returns in 13,000+ jurisdictions
- Accept legal liability for the transaction
- Handle chargebacks (you fight those yourself)
- Ensure compliance with EU consumer protection laws, GDPR data requirements, or local invoicing rules
With a payment processor, you are the merchant of record. You’re the legal seller. Everything that implies — tax obligations, fraud liability, dispute management — is yours to own.
What Is a Merchant of Record?
A merchant of record (MoR) is a company that legally becomes the seller of your product to your customers. When a customer in Germany buys your SaaS, they’re technically buying from Fungies.io (or Paddle, or FastSpring) — not from you directly. The MoR then passes the revenue to you after taking their fee.
This single structural difference changes everything. Because the MoR is the seller of record, they own:
- Tax registration and remittance in every jurisdiction
- VAT/GST collection and filing (EU, UK, Australia, Canada, and more)
- US state sales tax compliance across 45 taxing states
- Chargeback management and fraud prevention
- PCI DSS compliance
- Consumer protection and refund obligations
- Invoicing compliance (EU B2B invoicing rules, etc.)
You get a clean revenue share. They handle the legal complexity of global selling.
The Real Fee Comparison (It’s Not 2.9% vs 5%)
Most people compare Stripe’s 2.9% + $0.30 to Fungies.io’s 5% + $0.50 and conclude the processor is cheaper. That math is wrong.
When you use a payment processor to sell SaaS globally, here’s what compliance actually costs:
| Cost Item | Payment Processor (DIY) | Merchant of Record |
|---|---|---|
| Transaction fee | 2.9% + $0.30 | 5% + $0.50 (all-in) |
| Stripe Tax (if enabled) | +0.5% per transaction | Included |
| TaxJar / Avalara (annual) | $600–$2,400/year | Included |
| Accountant / tax advisor | $2,000–$10,000/year | Included |
| VAT registration (EU OSS) | 1–3 months + legal fees | Handled on day 1 |
| Chargeback management time | 2–5 hrs/month | MoR handles disputes |
| Finance team overhead | 20+ hrs/month | ~2 hrs/month |
At around $30,000 MRR with global customers, the hidden costs of a payment processor typically equal or exceed an MoR’s all-in pricing. Above that, the calculation only gets worse for DIY compliance.
And that’s before counting the one-time cost of getting it wrong — tax penalties, fines, or back-filing across multiple countries can run into five figures.
What Each Model Looks Like in Practice
Here’s a concrete scenario. You’re a solo founder with a SaaS at $15K MRR. Customers in the US, Germany, UK, and Australia.
With a payment processor (Stripe):
- You collect payments fine in the US
- Germany: you need EU VAT registration via OSS (One-Stop Shop)
- UK: separate UK VAT registration required post-Brexit
- Australia: GST registration required above AUD 75,000 threshold
- You need to file quarterly/annual returns in each jurisdiction
- If you miss any of this, you’re liable for back taxes + penalties
With Fungies.io (MoR):
- You embed the checkout, set your pricing
- Fungies automatically calculates the right VAT/GST per customer location
- Taxes are collected, filed, and remitted by Fungies in every country
- You never register for VAT in Germany, the UK, or Australia
- You just watch the revenue land in your account

When a Payment Processor Makes Sense
Don’t get me wrong — payment processors aren’t wrong. There are legitimate scenarios where they’re the right call:
- You sell exclusively in the US and have the sales tax handled via Stripe Tax or a service like TaxJar. One jurisdiction is manageable.
- You’re a platform building embedded payments. If payments are your product — you’re a vertical SaaS platform helping merchants get paid — you need the control that payment processors give you. An MoR sitting between you and your merchants doesn’t work.
- You have a finance team. If you’ve got 3+ people in finance who can handle tax filings, chargeback disputes, and compliance audits, you might save money at very high volume.
- You want maximum API flexibility. Stripe’s APIs are the industry benchmark. If you’re building complex custom billing logic, processor-level access gives you more control.
When a Merchant of Record Makes Sense
For most SaaS founders selling internationally, an MoR is the right default. Specifically:
- You’re selling to customers in 3+ countries. Multi-jurisdiction tax compliance becomes genuinely complex and time-consuming.
- You’re early-stage and don’t have a finance team. An MoR effectively gives you a compliance department for 5% per transaction.
- Speed to market matters. With Fungies.io, you can be live globally in under an hour. Setting up proper tax compliance with a processor takes months.
- You’re a solo founder or small team. Every hour you spend on VAT filings is an hour not spent on product. MoRs buy that time back.
- You’ve hit $5K–$30K MRR and are starting to go global. This is the exact inflection point where MoR economics make the most sense.
Key Takeaways
- A payment processor moves money. A merchant of record moves money AND takes legal/tax responsibility. These are categorically different products.
- Stripe’s 2.9% isn’t the full cost when you factor in tax software, accountant fees, and compliance overhead — especially above $10K MRR with international customers.
- At ~$30K MRR with global customers, total cost of ownership flips — an MoR’s all-in 5% often beats the DIY approach on pure economics, not just convenience.
- The global compliance burden is real: 13,000+ tax jurisdictions, separate UK/EU VAT registrations, Australian GST thresholds — an MoR eliminates all of it.
- If you’re building embedded payments as a product feature, a processor wins. If you’re selling SaaS or digital products, start with an MoR and reconsider when you have a compliance team.
FAQ
Is Stripe a merchant of record?
No, Stripe is not a merchant of record by default. You remain the legal seller when using Stripe. In April 2025, Stripe launched a beta “Stripe Managed Payments” feature that moves toward MoR-style tax handling, but it’s not universally available and doesn’t fully replace dedicated MoR platforms. With standard Stripe, you’re responsible for all tax collection, filing, and remittance.
Can I use both a payment processor and a merchant of record?
Yes. Some founders use Stripe for US-only domestic transactions (where a single tax jurisdiction is manageable) and a merchant of record like Fungies.io for all international transactions. This hybrid approach captures Stripe’s lower fees domestically while using an MoR’s compliance coverage globally. It does add integration complexity, so weigh that tradeoff.
What does a merchant of record cost vs a payment processor for a $20K MRR SaaS?
At $20K MRR with a 50% international customer mix: Stripe costs ~$580/month in transaction fees plus $600–$1,200/year in tax software, potentially $3,000+ in accountant fees, and 10+ hours per month in compliance overhead. Fungies.io at 5% + $0.50 costs roughly $1,050–$1,200/month all-in — with zero compliance overhead. The gap narrows fast when you account for the full picture.
Do I need a merchant of record if I only sell in the US?
Not necessarily. If you sell exclusively to US customers, you can manage sales tax with a processor + Stripe Tax or TaxJar. You’d still need to handle economic nexus across states if you cross thresholds, but it’s more manageable than multi-country compliance. If you have any international customers — even 10% — an MoR starts making sense immediately.
Conclusion
The merchant of record vs payment processor choice isn’t about which is “better.” It’s about which one matches your situation right now.
If you’re selling to global customers without a compliance team, an MoR isn’t just more convenient — it’s genuinely cheaper and dramatically lower risk when you count everything. The 2.1% price difference disappears the moment you factor in what DIY compliance actually costs.
Fungies.io is a merchant of record built specifically for SaaS founders who want to sell globally without building a finance department. 5% + $0.50, no monthly fees, tax handled in 180+ countries, and you can be live in under an hour.
