Key takeaways
- Standard PSP (like Stripe or Adyen): You’re still the official seller. Yes, these tools are easy to hook up to your app, but at the end of the day, you're the one on the hook for registering, figuring out, and paying sales tax wherever your customers live.
- Merchant of Record (like Paddle or Lemon Squeezy): They sell the software *for* you. Because they act as a middleman, they take over the boring legal stuff—like dealing with international taxes, fighting credit card chargebacks, and sending out invoices.
- Pros: The documentation is incredible—seriously, it's the gold standard. Plus, you can easily accept almost any payment method under the sun, from credit cards and Apple Pay to wire transfers.

The Best B2B Payment Gateways for Global SaaS in 2024
Let’s be honest: picking a payment gateway is a massive headache.
Once your SaaS starts growing outside your home country, you run straight into a wall of annoying problems. We're talking foreign currencies, local payment habits, subscription tracking, and—worst of all—international tax nightmares like VAT. (Who actually wants to spend their weekends reading tax code? Definitely not you.)
So, what are your options? This quick guide breaks down the top B2B payment gateways for global SaaS in 2024. We'll look at what they charge, what they actually do, and why you need to choose between a basic payment provider and a Merchant of Record.

Standard Payment Gateway vs. Merchant of Record (MoR)
First things first: you have a big decision to make. Before you write a single line of code or sign any contracts, you need to decide how you want to handle money internationally. This comes down to two very different setups:
Comparison Table: PSP vs. MoR
| Feature | Standard Gateway (PSP) | Merchant of Record (MoR) |
|---|---|---|
| Who handles taxes? | You do (using tools like TaxJar or Stripe Tax) | They do it automatically |
| Who deals with chargebacks? | You | They do |
| Invoices & Receipts | You have to build this or buy other tools | They handle it automatically |
| Average Cost | Lower (usually around 2.9% + $0.30) | Higher (usually around 5% + $0.50) |
| How fast do you get paid? | Almost instantly | Slower (usually once a month) |

Stripe is pretty much the default choice these days. Developers love it because the code is beautiful, and it plays incredibly well with other tools. You can build basically whatever checkout experience you want.
2. Paddle (The Tax-Saver MoR)
Paddle is built specifically for software companies. Because they act as your Merchant of Record, they take the tax target off your back. No more worrying about weird European tax laws or customer service emails asking for updated invoices.
3. Adyen (For the Big Leagues)
Adyen is built for massive, established brands. It’s a financial powerhouse that plugs your software directly into global banking networks.

Frequently Asked Questions (FAQ)
Which payment gateway is best for early-stage SaaS startups?
Honestly? Go with a Merchant of Record like Paddle. When you're just starting out, you need to focus on building a product people actually want—not spending weeks studying international tax law.
What is the difference between a payment gateway and a payment processor?
Think of the gateway as the digital card reader that grabs the customer's info at checkout. The processor is the engine under the hood that actually talks to the banks and moves the money.
How does sales tax work for SaaS products?
It’s a giant mess, to be blunt. Every country (and even different US states) has its own weird rules for taxing digital products. To stay out of trouble, you'll either need to pay for extra tools like Stripe Tax or just let a Merchant of Record handle the whole headache for you.
