Paddle vs Polar 2026: Polar.sh MoR Fees + Calculator

Compare Paddle vs Polar.sh when you want merchant-of-record coverage for a SaaS, developer tool, open-source project, or digital product. Check public fees, tax coverage, checkout fit, and billing workflow before you choose.

Paddle fit

Paddle is often considered by SaaS companies that want an established MoR workflow, subscription handling, global tax operations, buyer support, and a broader SaaS billing surface.

Polar fit

Polar is often considered by developer-focused products, open-source maintainers, and smaller teams that want a simple MoR-style path with developer-friendly positioning.

Compare beyond fees

Look at supported payment methods, subscription tools, invoices, tax handling, payout timing, refund handling, disputes, customer portal features, and migration risk.

Run scenarios

A low-ticket developer tool and a B2B SaaS with annual contracts can point to different providers. Model monthly orders, AOV, and international mix first.

Current public fee snapshot

Paddle's public pay-as-you-go checkout rate is 5% + $0.50 per Checkout transaction. Polar's public Starter plan is also listed at 5% + $0.50, while its paid Pro, Growth, and Scale plans trade a monthly fee for lower transaction rates.

Why the same headline fee can differ

If both providers start near the same public transaction fee, the real decision moves to product fit: developer workflow, support expectations, subscription features, buyer communication, payout handling, and how much billing depth your SaaS needs.

When Paddle can win

Paddle can be the stronger choice when the team wants fewer moving parts around global tax, invoices, buyer emails, failed payments, and subscription administration. The fee may look high, but it can replace finance and support work.

When Polar can win

Polar can be the stronger choice when the product is developer-led, simple to buy, and close to an open-source or creator audience. In that case, workflow fit and speed can matter more than a broad enterprise billing surface.

Compare the account lifecycle

The first checkout is only one step. Compare how each provider handles upgrades, downgrades, subscription pauses, failed renewals, customer portal access, invoice requests, refunds, and chargebacks. SaaS teams often discover the real difference after the first renewal cycle, not during launch week.

If you expect many plan changes, this workflow check matters as much as the base transaction rate.

Pick the simpler operating model

If both options produce similar net revenue, choose the provider that leaves fewer awkward manual processes. A small team benefits from fewer billing exceptions, clearer buyer receipts, and predictable payout workflows more than from a small modeled fee advantage.

Paddle vs Polar FAQ

Is Paddle cheaper than Polar.sh?

Not always. Compare the actual plan, order value, international mix, refunds, and the operational work each provider removes from the team.

Is Polar only for open-source projects?

No, but Polar is often evaluated by developer-first and open-source-adjacent products, so audience fit is part of the decision.

Should I choose a merchant of record for a small SaaS?

It can make sense when global tax and buyer operations would slow you down more than the extra bundled fee.
