Stripe or Paddle for an EU-based SaaS?

From the SoleOS answers series — written about our own product space; grounded in published definitions and documented behavior, never invented numbers.

If you're EU-based and selling SaaS, the honest answer is: Paddle if you want someone else to own VAT compliance and don't mind higher fees and less flexibility; Stripe if you want lower fees and full control and are willing to either handle VAT yourself (Stripe Tax) or bolt on a merchant-of-record layer later. There isn't a universally correct answer — it depends on how much of your time is worth spending on tax plumbing versus product.

This isn't a tax-advice post. It's a framework for deciding, based on how the two actually work.

The core structural difference

Stripe is a payment processor. You are the merchant of record. That means you're legally responsible for charging the right VAT rate per EU country, filing it (via VAT MOSS / OSS or local registrations), and keeping up with rate changes. Stripe Tax can calculate and collect the right amount automatically, but it doesn't file returns for you — you still need to remit what it collects, either yourself or through an accountant or a service like Quaderno.

Paddle is a merchant of record (MoR). Paddle buys your product from you at wholesale and resells it to your customer, which means Paddle — not you — is responsible for collecting and remitting VAT across every jurisdiction it supports. You get one net payout; VAT is Paddle's problem. That's the entire pitch, and it's genuinely valuable if you don't want to think about tax residency rules for 27 different countries.

The tradeoff is fees. Paddle's all-in pricing runs noticeably higher than Stripe + Stripe Tax, because you're paying for the compliance layer bundled in. For a solo founder with modest MRR, that spread can be a meaningful chunk of revenue once you're past a few thousand dollars a month.

When Paddle is the right call

• You're selling B2C or prosumer subscriptions across many EU countries and don't want to register for OSS or deal with rate tables.
• You have zero appetite for tax admin and would rather pay a few extra percentage points than hire an accountant or learn VAT rules.
• You're pre-revenue or early and want to ship fast without worrying about compliance edge cases.
• You sell digital products to consumers where VAT obligations kick in from the first sale (there's no small-business threshold for digital services sold cross-border into the EU from most setups).

Paddle also handles invoicing, dunning, and some tax edge cases (like reverse charge for B2B customers) out of the box, which removes several smaller headaches beyond just VAT.

When Stripe is the right call

• You're comfortable using Stripe Tax (it calculates VAT automatically and files-ready reports) and either file your own OSS return or pay an accountant a flat fee to do it quarterly.
• You care about the lower processing fees and want them to compound as you scale across multiple products — the fee gap matters more in aggregate once you're running several apps.
• You want granular control over checkout, subscription logic, metered billing, or custom invoicing that Paddle's more opinionated checkout doesn't support as flexibly.
• You already use Stripe for one product and want billing data to look the same everywhere so you can read your whole portfolio the same way. If you're also pulling in RevenueCat for mobile subscriptions, see tracking Stripe and RevenueCat together for how to keep both consistent.

For a solo founder running more than one product, Stripe's flexibility usually wins once you've validated a product and are optimizing margins — the fee savings scale with your portfolio, while the VAT admin burden, once you set up OSS filing once, doesn't grow much per additional product.

The B2B wrinkle

If most of your customers are EU businesses with a valid VAT number, reverse charge often applies and you may not need to collect VAT at all on those invoices. This simplifies things substantially under either provider, but you still need to validate VAT numbers (VIES) and keep records. Paddle automates this validation; on Stripe you'd configure Stripe Tax or a third-party tool to do it. If your customer base skews B2B, the VAT complexity argument for Paddle weakens considerably — you may be fine with Stripe + Stripe Tax from day one.

What actually changes your decision as you scale

The calculus shifts as you add products. A few things worth checking before you commit:

• Fee delta in dollars, not just percentage. Model your actual MRR through both fee structures. The percentage gap matters less at $500 MRR than at $15,000 MRR.
• Filing cadence you can sustain. OSS returns are typically quarterly. If you're already stretched thin running several apps, that's a recurring task you need to actually do, not just plan to do.
• Consistency across your portfolio. If one product runs on Stripe and another on Paddle (or RevenueCat for mobile), your reporting gets fragmented fast. Decide whether you want one billing provider per product or portfolio-wide consistency — this affects how easily you can compare products side by side later.
• Switching cost. Migrating billing providers mid-flight is painful — customer re-authorization, dunning resets, and historical reporting gaps. Pick with the next 12-18 months in mind, not just this quarter.

Where SoleOS fits (and where it doesn't)

Disclosure: SoleOS is a billing-and-analytics tool for multi-product founders, so take this with the appropriate grain of salt — we're writing about a space we sell into.

SoleOS connects to Stripe directly (OAuth, metrics-only) to pull revenue, MRR, and churn into one dashboard alongside RevenueCat for mobile and your web analytics. It doesn't currently have a native Paddle connector, so if you go the Paddle route, you'd be tracking that product's revenue outside SoleOS for now — worth knowing before you decide, not after. If you run everything on Stripe across several apps, that's where the portfolio view is most useful: one place to see MRR and churn trends across every product instead of logging into each Stripe dashboard separately. You can check the live demo with sample data to see what that looks like, or read the metrics dictionary for exact MRR/churn formulas.

If you only run one product, or you're happy reading Stripe's own dashboard and exporting a CSV monthly, you don't need SoleOS yet — a spreadsheet works fine at that scale, and SoleOS vs a spreadsheet walks through when the switch actually pays off.

Frequently asked questions

Does Paddle completely remove my VAT obligations?

For products Paddle sells as merchant of record, yes — Paddle remits VAT on those transactions. You still need to handle VAT correctly for anything sold outside Paddle (physical goods, other products, consulting), and you should keep your own records for your accountant regardless.

Can I use Stripe Tax without hiring an accountant?

Stripe Tax calculates and collects the correct VAT rate automatically. Filing the return is a separate step — some founders do it themselves through their country's OSS portal, others use a service like Quaderno or Lovat layered on top of Stripe, and some pay an accountant a flat quarterly fee. Stripe Tax alone doesn't file for you.

Is Paddle more expensive for every founder?

Not necessarily in total cost — once you factor in what you'd otherwise pay for a VAT compliance service or accountant hours, the gap narrows. It's most expensive relative to Stripe when your volume is high and your compliance needs are simple (e.g., mostly B2B with reverse charge).

Can I run different products on Stripe and Paddle at the same time?

Yes, plenty of founders do this — Paddle for a consumer app with heavy EU VAT exposure, Stripe for a B2B product with reverse-charge customers. The cost is fragmented reporting: you'll need to pull revenue from both to see true portfolio-wide numbers, which is exactly the kind of gap tools like Baremetrics or SoleOS try to close for Stripe-based products specifically.

What about non-EU customers if I'm EU-based?

Both Stripe Tax and Paddle handle US sales tax and other international VAT/GST regimes to varying degrees. Check current jurisdiction coverage for each before assuming either one is fully global — coverage changes as both companies expand, so verify against your actual customer countries rather than general reputation.
