Prices verified 2026-05-15. Key facts: Stripe Billing pay-as-you-go 0.7%, Polar effective rate 6% + $0.40 on international subscriptions, Lemon Squeezy still operating independently at 5% + $0.50, Stripe's $1B Metronome acquisition closed 2026-01-13.
TL;DR — 30-second decision
- US-resident, selling digital products direct, MRR under $10K → Polar — lowest effective rate, fastest setup, VAT handled
- Non-resident (e.g., Korea-based US LLC), don't want to touch VAT/GST → Paddle — Merchant of Record, tax fully handled, 24/7 support
- SaaS subscriptions, team, complex billing logic → Stripe Billing — best API; tax is your problem
- Currently on Lemon Squeezy → Stay, but verify your migration plan to Stripe Managed Payments before any new feature work
- MRR above $50K, optimizing rates → Stripe direct + Avalara or TaxJar is worth modeling

Tool quick intros
Stripe
Founded: 2010 · HQ: San Francisco, CA · Status: Independent (IPO speculation ongoing)
The de facto payments API. Maximum flexibility; tax is your problem.
The industry standard. Acquired Metronome ($1B, Jan 2026) — usage-based billing capabilities leveling up significantly. Stripe Managed Payments (Merchant of Record) is in public preview as a separate product from Lemon Squeezy.
Paddle
Founded: 2012 · HQ: London, UK · Status: Independent
Merchant of Record. VAT, GST, and US sales tax handled and remitted by Paddle.
Strongest 24/7 support among MoR options. Effective rate runs ~7–8% on international sales once the undisclosed FX margin is included — the "no hidden fees" marketing and the reality are not the same thing.
Polar
Founded: 2023 · HQ: Remote (open-source) · Status: Growing fast
Open-source friendly MoR with GitHub-native flows. Headline 4% + $0.40.
Effective rate jumps to 6% + $0.40 on international subscriptions (+0.5% subscription surcharge, +1.5% non-US card pass-through). Smaller team; community has reported support delays in early 2026.
Lemon Squeezy
Founded: 2021 · HQ: Remote · Status: Acquired by Stripe (Jul 2024) — still operating
Indie-friendly MoR, still live at 5% + $0.50. Stripe Managed Payments is the long-term successor but is a separate product, not an automatic migration.
Existing users: fine for now. New entrants should prefer Polar or Paddle until the migration story is settled.
Decision tree
Selling digital products / SaaS globally?
→ Can you handle VAT / GST / US sales tax yourself?
No / non-resident → Use a Merchant of Record:
- MRR under $10K → Polar
- B2B + team + need 24/7 support → Paddle
- Already on it → Lemon Squeezy (only if existing customer)
Yes (or have an accountant) → Choose by MRR:
- Under $50K, no complex billing → Polar
- Under $50K, complex billing logic → Stripe Billing
- Over $50K → Stripe + Stripe Tax or Avalara
Dimension comparison
Tax / compliance automation
| Tool | Rating | Notes |
|---|---|---|
| Stripe | 🟡 Add-on | Stripe Tax (0.5%/tx no-code, $0.50/tx API, or $90/mo Complete) calculates and collects — but you file and remit. US sales tax economic nexus is your problem. VAT registration is your problem. |
| Paddle | ✅ Full MoR | True Merchant of Record. Paddle is the legal seller of record, files and remits VAT, GST, US sales tax. Single strongest reason for non-residents to choose it. |
| Polar | ✅ Full MoR | MoR included. Handles sales tax / VAT. Open-source friendly with GitHub-native flows. |
| Lemon Squeezy | ✅ Full MoR | Equivalent to Paddle in scope. Post-acquisition policy stability is the open question. |
Fee structure transparency
| Tool | Rating | Notes |
|---|---|---|
| Stripe | ✅ Transparent | All add-ons are explicit and additive. 2.9% + $0.30 domestic, +1.5% international, +1% FX, +0.7% Billing, +0.5% Tax. Most transparent vendor in the category. |
| Paddle | 🔴 Misleading | Sticker 5% + $0.50. FX margin NOT disclosed publicly — community estimates 2–3% spread vs mid-market rate → effective rate 7–8.5% on international sales. |
| Polar | 🟡 Buried | 4% + $0.40 headline, but +0.5% subscription and +1.5% non-US card surcharges are in the docs, not the pricing page. |
| Lemon Squeezy | 🟡 Partial | 5% + $0.50 sticker holds. FX margin similarly undisclosed. |
API / billing logic flexibility
| Tool | Rating | Notes |
|---|---|---|
| Stripe | ✅ Best-in-class | Usage-based, per-seat, multi-plan, complex proration — all native. Metronome acquisition expanding usage-based capabilities further. |
| Paddle | 🟡 Capable | Paddle Billing API is capable but not at Stripe's level. Custom proration and multi-tier plans are doable, not effortless. |
| Polar | 🟡 Solid for indie | Strong for digital products and indie SaaS. Complex multi-tier B2B billing is less mature. |
| Lemon Squeezy | 🟡 Indie-friendly | Heavy seat/usage models are awkward. |
Time to first sale
| Tool | Rating | Notes |
|---|---|---|
| Stripe | 🔴 Slowest | Stripe Tax + Billing without a developer takes days. Webhooks, subscription state, and dunning all need glue code. |
| Paddle | 🟡 2–3 days | Checkout embed gets you live quickly. Slower than Polar. |
| Polar | ✅ Same day | GitHub integration ships same-day. Fastest non-LS option. |
| Lemon Squeezy | ✅ 30 minutes | Code-free store fastest path. |
Data portability / migration difficulty
| Tool | Rating | Notes |
|---|---|---|
| Stripe | ✅ Best | Clean data export, largest migration tooling ecosystem, subscription portability via PaymentMethod tokens. |
| Paddle | 🟡 Workable | Standard subscription exports. Active subscription migration requires customer re-consent under MoR rules — expect practical churn on transfer. |
| Polar | 🟡 Open-source upside | Open-source means self-hosting is eventually possible. Migration tooling ecosystem is thin. |
| Lemon Squeezy | 🟡 ⚠️ Uncertain | Standard exports. The eventual Stripe Managed Payments migration path is opaque — affiliate tools, digital download delivery, and storefront builder are NOT in Managed Payments. |
Company stability / risk
| Tool | Rating | Notes |
|---|---|---|
| Stripe | ✅ Effectively zero risk | Industry standard. Sunset risk negligible. |
| Paddle | ✅ Solid | Independent, well-funded, recognized brand in B2B SaaS. |
| Polar | 🔴 Early-stage | Founded 2023. Reasonable for sub-$50K MRR; would not pin a Series A business to it without a backup plan. |
| Lemon Squeezy | 🔴 Roadmap unclear | Stripe's investment is going to Managed Payments, not the LS product. Post-acquisition velocity has slowed visibly. |
Pricing scenarios
Assumptions: Digital products / SaaS, US-primary audience. Average ticket $49. International card share 30%. Monthly transaction count = MRR ÷ $49. Disputes excluded.
These are computed estimates, not invoices. Sticker = headline rate math. Effective = what actually leaves your account with add-ons, FX margin, and surcharges applied.
Early stage — MRR $1,000 (~21 transactions/month)
| Tool | Sticker / mo | Effective / mo | Notes |
|---|---|---|---|
| Stripe | ~$35 | ~$82 (8.2%) | With Billing 0.7% + Tax 0.5% + intl/FX on 30%. Turning on Billing + Tax wipes the headline advantage entirely at this MRR. |
| Paddle | ~$60 | ~$68–72 (6.8–7.2%) | Includes VAT and US sales tax filing. Compare against $200–500/mo for outsourced multi-state filings before judging the fee. |
| Lemon Squeezy | ~$60 | ~$64 (6.4%) | Cost equivalent to Paddle. Support response times have degraded post-acquisition. |
| Polar | ~$48 | ~$56 (5.6%) | Lowest effective rate of the MoR options. Trade-off: company maturity at 2 years old. |
Recommendation: Polar. Lemon Squeezy only if you're already on it.
Growth — MRR $10,000 (~204 transactions/month)
| Tool | Sticker / mo | Effective / mo | Notes |
|---|---|---|---|
| Stripe | ~$685 | ~$805 (8.05%) | Around here, outsourced US sales tax ($100–300/mo) vs MoR premium becomes a real comparison. |
| Paddle | ~$600 | ~$680–750 (6.8–7.5%) | Pricing edge over Stripe shrinks. B2B features (invoicing, ACH) and 24/7 support justify the gap. |
| Lemon Squeezy | ~$600 | ~$640 (6.4%) | Same fee as Paddle, less support certainty. Migration risk to Stripe Managed Payments overhang is real. |
| Polar | ~$480 | ~$560 (5.6%) | Still cheapest in absolute terms. Maturity/support risk is what you're underwriting. |
Recommendation: Polar (cost) / Paddle (B2B + tax certainty) / Stripe (complex billing or team).
Scale — MRR $50,000 (~1,020 transactions/month)
| Tool | Sticker / mo | Effective / mo | Notes |
|---|---|---|---|
| Stripe | ~$3,420 | ~$4,020 | Volume negotiation starts mattering — 20–30% off is achievable. Interchange+ pricing worth requesting. |
| Paddle | ~$3,000 | ~$3,375–3,800 | MoR premium over Stripe shrinks at scale. Time to model Stripe-direct migration seriously. |
| Lemon Squeezy | ~$3,000 | ~$3,200 | Platform-risk cost (Stripe MP transition) starts being real money at this MRR. |
| Polar | ~$2,400 | ~$2,800 | Cost lead intact but pinning a $50K MRR business to a 2-year-old vendor is its own risk category. |
Recommendation: Seriously model Stripe + Avalara/TaxJar. Negotiate Paddle volume in parallel.
2026 updates
Stripe acquires Metronome — $1B, January 2026
Stripe completed its $1B acquisition of usage-based billing platform Metronome on January 13, 2026. Metronome was the metering backbone for OpenAI, Anthropic, and Nvidia. The practical read: if you're building an AI product with metered pricing, Stripe's native capabilities are about to become significantly stronger. Patrick Collison framed it as a bet that "the shift toward usage-based models will be a defining feature of the next decade."
Stripe Managed Payments enters the MoR market
Stripe Managed Payments is in public preview, expanding to 35+ countries. Pricing watch: roughly 5% + $0.50 on top of the standard 2.9% + $0.30 Stripe Payments fee — making it ~3.5% more expensive than the headline suggests. It is currently the most expensive MoR in this comparison. Strategically interesting (MoR built on Stripe infra), economically not yet competitive.
Lemon Squeezy — still independent, migration path TBD
Lemon Squeezy continues to operate at 5% + $0.50. Stripe Managed Payments is a separate product, not an auto-migration target. Features LS merchants depend on — affiliate tools, digital download delivery, storefront builder — are NOT in Managed Payments. Slower support response and reduced product velocity during the integration period have been widely reported. New entrants should look elsewhere; existing merchants are not in crisis but should have a contingency plan.
Polar's growth
Founded 2023, Polar started as a GitHub Sponsors alternative and expanded into SaaS subscriptions and digital products through 2024–2025. Adoption among indie/open-source teams is growing. Caveats: community-reported slow support in early 2026; payout coverage ~120 countries via Stripe Connect Express, narrower than Paddle's 200+.
Pitfalls and gotchas
Polar: headline vs effective rate
⚠️ Trap. Polar's marketing leads with 4% + $0.40, but the fees docs list +0.5% on subscription renewals and +1.5% on non-US cards (Stripe pass-through). On a subscription SaaS with 40–60% international customers, your effective rate is 6% + $0.40 — 50% higher than the sticker. At $25K MRR that's $500–640/month more than the pricing page suggests.
Stripe: the effective rate with everything on
⚠️ Trap. Each Stripe add-on is small; together they stack. Domestic base 2.9% + $0.30, then international +1.5%, FX +1%, Billing +0.7%, Tax (no-code) +0.5% — on an international subscription that's 6.6% + $0.30. The "Stripe is cheap" prior depends on turning add-ons off, which is rarely realistic for a real SaaS.
Paddle: sticker vs effective
⚠️ Trap. Paddle's pricing page reads "5% + $0.50, no hidden fees." The FX margin (~2–3% spread vs mid-market on non-USD payouts) is not on that page but very much in your payout. International-heavy sellers should expect 7–8.5% effective, not 5%. Run the math against your own payout currency before signing.
Stripe: "tax is your problem"
⚠️ Trap. Stripe is best-in-class payments infrastructure, not an MoR. US sales tax — once you trip economic nexus in a state — is on you. EU/UK VAT, AU GST, registration in each jurisdiction: also on you. Stripe Tax (0.5%) helps calculate and collect; filing and remittance remain your obligation. For non-residents, this is a meaningful operational burden.
Lemon Squeezy: acquisition uncertainty
⚠️ Trap. If you're on LS: confirm whether fees, features, or support SLAs are changing, and inventory which LS-specific features (affiliate links, digital download delivery, storefront builder) you rely on — none of those are in Stripe Managed Payments. Switching payments infra mid-life always costs active subscribers; don't let this migration happen reactively.
Subscription migration churn
When you switch providers with active subscribers, customers typically need to re-enter their card. Industry-observed loss rates run 10–30% of active subscriptions in the first month. The bigger your MRR, the more expensive the migration — model it before, not during.
When to switch
Solo founder, US-resident (P1):
- MRR under $5K: optimize for setup speed → Polar (or LS if already on it)
- MRR $5–30K: evaluate Stripe Billing once you need complex plans or a team; trigger is usually per-seat or usage-based pricing
- MRR $30K+: Stripe + Stripe Tax or Avalara; bring in an accountant
Non-resident operating a US LLC (P2):
- Start with an MoR (Paddle or Polar) — multi-state US sales tax registration is impractical for non-residents
- At MRR $30K+, recompute Paddle vs Stripe-direct including accountant cost; the crossover is real but later than intuition suggests
Seed startup, 2–5 people (P3):
- MVP / discovery: Polar or Paddle (fast setup)
- Post-product-market-fit: model the Stripe Billing migration; trigger = usage-based billing, multi-seat plans, or enterprise contracts
- Budget 1–2 engineer-weeks plus expected subscriber churn for the move
