Polar charges 4% + $0.40 flat with zero extra fees on international cards.

Step 3: Lemon Squeezy Total Deductions
($10,000 × 5%) + (345 × $0.50) + ($3,500 Int'l × 1.5%) + ($2,000 PayPal × 1.5%) + $1 Payout = $756.00 (7.56% Take Rate)

Merchant Margin Takeaway: Protecting net profit margins requires analyzing the compound drag of marketplace referral commissions and gateway processing fees. Raising Average Order Value (AOV) significantly dilutes fixed transaction fee impact.

  • Payment Gateway Fees: Credit card processing rates (standard 2.9% + $0.30 per successful charge).
  • Fulfillment & Parcel Surcharges: Pick-pack fees, dimensional weight charges, and carrier fuel adjustments.

Frequently Asked Questions

What is the difference between Polar.sh, Lemon Squeezy, and Paddle?

All three are Merchants of Record (MoRs) that act as the legal reseller of your software to handle global sales tax, VAT, and invoices. Polar.sh caters specifically to developers and open-source creators with lower 4% + $0.40 fees and zero international card surcharges. Lemon Squeezy offers rich email marketing and affiliate tools, while Paddle specializes in high-MRR B2B SaaS.

Why does Lemon Squeezy charge a 1.5% international surcharge?

Lemon Squeezy passes along cross-border transaction fees charged by card networks when a customer uses a non-US credit card or checks out through PayPal.

Does Polar.sh support recurring subscriptions and license keys?

Yes. Polar supports monthly/annual subscriptions, usage-based billing, Discord role automation, GitHub benefits, and license key generation.

How much can I save by choosing Polar over Lemon Squeezy?

At $10,000 monthly MRR with 35% international customers, Polar costs $538/month versus Lemon Squeezy's $756/month, saving you $218 per month ($2,616 annually).

Can I use Stripe directly instead of a Merchant of Record?

Yes, but Stripe is a payment gateway, not an MoR. Using Stripe directly requires you to calculate, collect, register for, and remit sales tax and VAT across 40+ countries and US states yourself.
