Polar vs Stripe vs LemonSqueezy in 2026: which one to actually pick

You have a product and a price, and now you need a way to actually take money. The three options most founders end up comparing right now are Polar, Stripe, and LemonSqueezy. Stripe also has a newer option called Stripe Managed Payment (now public out of private beta) that changes the calculation a little.

I have shipped products on all of these, and goilerplate ships both Polar and Stripe wired up out of the box so I have to keep up with both APIs. This is the comparison I wish someone had handed me the first time.

TL;DR

	Polar	Stripe (Classic)	Stripe Managed Payment	LemonSqueezy
Type	Merchant of Record	Payment Processor	Merchant of Record	Merchant of Record
Handles your VAT/sales tax	yes	no (you do, or pay Stripe Tax)	yes	yes
Base fee	4% + $0.40 (US)	2.9% + $0.30 (US)	3.5% on top of standard processing	5% + $0.50
Effective fee	~4% + $0.40 baseline	~3.4% with Tax add-on	~6.4% + $0.30 (US), ~5.0% + €0.25 (EEA)	~5% + $0.50
Surcharges to expect	+1.5% intl cards, +0.5% subs	+0.5% Stripe Tax, +1.5% intl	already factored above	rolled into base
Subscription support	yes	yes (best in class)	yes	yes
One-time payments	yes	yes	yes	yes
Payout speed	4 to 7 business days (manual trigger)	2 days (US established)	similar to Classic	13-day rolling, paid 1st/15th
Developer experience	excellent, modern	the industry standard	Stripe API plus MoR	good
Webhook reliability	excellent	excellent	excellent	excellent
Best for	indie SaaS and small teams that want MoR	scale, complex billing, US-only or with a tax team	teams that want Stripe API and MoR	digital products with license keys

The short version: Polar is the default for new indie SaaS in 2026. Stripe (Classic) when you have a tax team or sell US-only. Stripe Managed Payment if you want the Stripe API but also want someone else to handle tax. LemonSqueezy if you sell license keys or you are already on it.

Read on for the why.

Merchant of Record vs Payment Processor

This is the most important distinction and the one most founders skip past.

A payment processor (Stripe Classic) charges the customer and gives you the money. The legal merchant is you. You are responsible for VAT in the EU, GST in the UK and Australia, sales tax in the US, and so on. You file the returns, you handle the audits.

A Merchant of Record (Polar, LemonSqueezy, Paddle, and now Stripe Managed Payment) charges the customer in their own name. They collect VAT and sales tax, they remit it to the right tax authority, they handle audits. You receive a clean payout net of fees and taxes.

The interesting development in 2026 is that Stripe now sits on both sides of this line. Classic Stripe is still a payment processor. Stripe Managed Payment is their newer MoR offering, now public out of private beta, designed to compete directly with Polar, LemonSqueezy, and Paddle.

If you are selling to a global audience, the MoR model saves you genuinely staggering amounts of accounting time. EU VAT rules alone are a research project of their own.

If you are selling only in the US, Stripe Classic with Stripe Tax is a fine option. If you have any meaningful international traffic, MoR (any flavor) is what you want.

Polar

Polar is the newcomer that grew up fast. Their MoR billing product opened to general SaaS use in the 2024-2025 window and they have been shipping aggressively since.

What is good:

Modern API, excellent SDKs (TypeScript, Python, Go).
Merchant of Record. They handle VAT, GST, sales tax.
Generous free tier (no monthly minimums).
Excellent customer support. You actually talk to humans.
Built by people who themselves run indie SaaS.
Webhook signatures, idempotency keys, retries, all done right.
Subscriptions, one-time payments, license keys, customer portal.
Cheaper than LemonSqueezy on most price points.

What is not great:

Newer than Stripe and LemonSqueezy. Less battle-tested on edge cases.
Payouts are manually triggered and typically arrive in 4 to 7 business days. Not as fast as Stripe’s 2-day automatic payouts.
Some advanced billing features (deep metered billing, complex usage tiers) are simpler than Stripe’s.
Smaller ecosystem of third-party integrations.

Pricing: 4% + $0.40 per transaction is the headline. International cards add 1.5%, subscriptions add 0.5%. Check the Polar fees page for the current schedule before you build a financial model around it.

Verdict: the default choice for new indie SaaS in 2026. Best balance of MoR convenience, modern API, and indie-friendly pricing.

Stripe (Classic)

Stripe is the giant. The default payment processor for serious SaaS since 2014. The API is the industry standard. Every developer has touched it at some point. This section is about Classic Stripe (the payment processor). Stripe Managed Payment (the MoR offering) gets its own section below.

What is good:

The best developer experience in the payments world. Probably the best API of any company, full stop.
Massive feature surface: subscriptions, metered billing, tiered pricing, invoicing, payment links, ACH, SEPA, BNPL, gift cards, you name it.
Excellent webhook reliability and idempotency.
2-day payouts for established US accounts.
The brand. “We pay with Stripe” is a trust signal.
Stripe Tax (paid add-on) handles tax calculation, though you still file returns.
Stripe Atlas if you need to incorporate.

What is not great:

Classic Stripe is not a Merchant of Record. You are. International tax is your problem unless you pay Stripe Tax (0.5% surcharge), and even then, you still file the returns.
Fees are 2.9% + $0.30 (US). Cheap on processing alone, but add Stripe Tax and an international card surcharge and you are at roughly 4 to 5% all-in for global checkouts.
Complex price book. Stripe has a feature for every billing model under the sun, which means the API surface is huge.
Strong incentive to lock you in (Atlas, Capital, Issuing, and adjacent products).

Pricing: 2.9% + $0.30 standard US. Stripe Tax adds 0.5%. International cards currently add 1.5%. ACH is 0.8% capped at $5. Always check the current Stripe pricing page before you budget.

Verdict: the right choice when you have international tax help (an accountant or Avalara) or when you sell B2B in a single country. Past a certain MRR, the savings on fees vs Polar can fund the tax overhead. If you want the Stripe API but also want MoR, skip this section and look at Stripe Managed Payment below.

Stripe Managed Payment

Stripe Managed Payment is the most interesting payments development of 2026 for indie founders. It moved out of private beta into public availability, which means anyone can now use Stripe with Merchant of Record handling on top.

What is good:

Same Stripe API everyone already knows.
Merchant of Record. Stripe handles VAT, sales tax, GST.
One vendor for both processing and MoR if you are already on Stripe.
All the Stripe webhook reliability and tooling you already trust.

What is not great:

Newer than Polar’s MoR product. Fewer real-world reports in the wild.
Stripe’s incentive to keep you in the Stripe ecosystem is unchanged, just now with MoR added.
Pricing model is closer to Polar than to Classic Stripe, so the “Stripe is cheaper” assumption from the Classic comparison does not hold here.

Pricing: Stripe Managed Payment charges 3.5% on top of standard Stripe payment processing fees. That means for a US card transaction you are paying 2.9% + $0.30 (standard processing) plus 3.5% (Managed Payments) for an effective rate of around 6.4% + $0.30. For an EU/EEA card you are looking at roughly 5.0% + €0.25. Verify on the current Stripe pricing page before you commit, but that is the structure as of writing.

Verdict: great option if you already have Stripe Classic wired up, want MoR without switching vendors, and the fee math works for your geography and price point. For US-heavy projects, Stripe Managed Payment can come out meaningfully more expensive than Polar. For EU-heavy projects on EEA cards, the gap is much smaller. Run the math on your own pricing and volume mix before picking.

LemonSqueezy

LemonSqueezy launched as the indie-friendly MoR alternative to Paddle. Stripe acquired it in July 2024. It still operates as a separate brand and product, and so far the buying experience has not changed for sellers.

What is good:

Merchant of Record. Tax handled.
Great for digital products (ebooks, templates, themes, software licenses).
Clean checkout UI.
License key management built in (huge for selling code).
Affiliate program built in.

What is not great:

5% + $0.50 fees are higher than Polar.
Payouts run on a 13-day rolling schedule, processed on the 1st and 15th of each month. So a sale on day 1 might wait until the 15th, then take 13 more days to land. Plan around it.
Stripe acquisition means strategic direction is now Stripe’s. So far no breakage, but the long-term roadmap is theirs.
Subscription features are less rich than Stripe or even Polar.

Pricing: 5% + $0.50 per transaction. Confirm on the LemonSqueezy pricing page.

Verdict: still a fine choice if you are already on it or you are selling digital products with license keys. For new projects in 2026, Polar is cheaper and the developer experience is at least as good.

What this looks like in code

A quick taste of each provider’s Go API for the most common operation: creating a checkout session. These are simplified for readability and align with the SDK structures as of writing. Always check the current SDK docs for exact types.

Polar (polarsource/polar-go)

res, err := client.Checkouts.Create(ctx, components.CheckoutCreate{
    Products:      []string{productID},
    SuccessURL:    polargo.String(successURL),
    CustomerEmail: polargo.String(customerEmail),
    Metadata:      metadata,
})
// ...
http.Redirect(w, r, res.Checkout.URL, http.StatusSeeOther)

Pointer wrapper helpers (polargo.String, polargo.Bool) for nullable fields, same idea as Stripe’s *string pattern. The SDK is generated, which keeps the types honest.

Stripe (stripe/stripe-go)

params := &stripe.CheckoutSessionParams{
    Mode:          stripe.String(string(stripe.CheckoutSessionModeSubscription)),
    SuccessURL:    stripe.String(successURL),
    CustomerEmail: stripe.String(email),
    LineItems: []*stripe.CheckoutSessionLineItemParams{
        {Price: stripe.String(priceID), Quantity: stripe.Int64(1)},
    },
    Metadata: map[string]string{"user_id": strconv.FormatInt(userID, 10)},
}
session, err := session.New(params)
// ...
http.Redirect(w, r, session.URL, http.StatusSeeOther)

For Stripe Managed Payment, you add a ManagedPayments block to the checkout session params (stripe.CheckoutSessionManagedPaymentsParams{...}). Same SDK, MoR semantics on top.

LemonSqueezy

LemonSqueezy does not ship an official Go SDK at time of writing. You either use the JSON API directly or one of the community libraries. The rough shape of a JSON-API checkout call:

// Direct REST call via http.Client, or a community SDK wrapping the
// JSON:API response structure that LemonSqueezy returns. The checkout
// URL you redirect the user to lives at data.attributes.url in the
// response payload.

Less ergonomic than the other three, but workable.

Webhooks

All three providers send webhooks. All three sign them. Verify the signature. Reject anything that does not validate.

The three patterns to nail:

Idempotency. A webhook can fire twice. Your handler must produce the same result.
Out-of-order delivery. Newer events can arrive before older ones. Use created_at to detect.
Replay safety. Store the event ID for 30 days. Reject duplicates.

All three providers retry failed webhooks with exponential backoff. Take advantage. If your handler can fail safely, return 500 and let them retry.

Currency, locale, and customer experience

Polar and LemonSqueezy auto-detect customer country and show prices in their local currency. Both convert at the time of payment. Both display the correct VAT label.

Stripe does this too if you use Stripe Tax + Adaptive Pricing. Without those, your checkout shows USD to a customer in Germany, which is a small but real conversion hit.

For checkout conversion in a global B2C SaaS, the MoR providers have a small but real edge.

Pricing for refunds and disputes

Polar: no extra fees for refunds, except the original processing fee is non-refundable (industry standard).

Stripe: same as Polar.

LemonSqueezy: same.

Disputes: all three charge $15 to $25 per dispute. Most disputes can be auto-evidenced (Polar and Stripe both have good support for this). Some will go against you. Build dispute monitoring into your admin UI.

Country availability

In 2026:

Polar accepts merchants from most of North America, Europe, and APAC. Check their list.
Stripe is in 47+ countries.
LemonSqueezy is in 30+ countries.

For most indie founders this is a non-issue. If you are in a smaller market, check the merchant onboarding list for each.

My recommendation

If you are starting a new project in 2026 and you are not sure which to pick: Polar.

The MoR model alone saves you weeks of accounting research. The fees are reasonable. The API is modern. The team is responsive. It is the best default for the indie use case.

If you are already on Classic Stripe and shipping, and your business is mostly domestic or you have an accountant: stay on Stripe Classic. The migration cost is real, and Stripe is excellent.

If you are on Stripe and want MoR without changing vendors: Stripe Managed Payment is the new natural answer. Same API, plus MoR. The honest tradeoff is the fee stack: Stripe Managed Payment is 3.5% on top of standard processing, so on US cards it lands around 6.4% + $0.30 effective, which is meaningfully higher than Polar’s 4% baseline. On EU/EEA cards the gap is much smaller. Do the math on your real volume before picking.

If you are LemonSqueezy-pilled or you sell digital downloads with license keys: LemonSqueezy is fine. Just know that Polar does the same job for less money.

In goilerplate

goilerplate ships two Merchant of Record options out of the box: Polar and Stripe Managed Payment. A single env variable, PAYMENT_PROVIDER=polar (default) or PAYMENT_PROVIDER=stripe (which uses Stripe Managed Payment), flips between them. The provider interface lives under internal/service/payment/ so the rest of your app talks to a stable abstraction. You are never locked in.

Both options handle VAT and sales tax for you. Both have signed, idempotent webhooks. Both are wired into the same subscription lifecycle. You pick based on your geography, your fee preferences, and which API you already trust.

More providers are on the roadmap (likely LemonSqueezy, Paddle, and others) via the same provider-interface pattern. Lifetime updates means every new provider integration lands in your copy too.

Starting at $99 launch (regular $199), one-time. Same code I run for my own products. New features and fixes ship into goilerplate every week.

For the broader stack reasoning, see the best Go SaaS stack in 2026. For the head-to-head with the Next.js boilerplate options, see goilerplate vs supastarter vs ShipFast. For the cost math on building everything yourself, see boilerplate saves you 200 hours.

Whichever payment provider you pick, the principles are the same. Charge the customer, verify the webhook, fulfill the order, log enough that you can answer support tickets six months from now.

Now go build a product worth paying for.
