Best Merchant of Record for SaaS in 2026

The only major MoR whose published pricing falls meaningfully below 5% once you have real volume.

Polar wins on the thing that actually compounds: rate. It used to market a flat 4% + 40c and has since restructured into tiers, which reads like a price rise and, for the smallest sellers, is one. The free Starter tier now matches the category at 5% + 50c. But the paid tiers go where nobody else publishes: 3.8% + 40c at $20 per month, 3.6% + 35c at $100, and 3.4% + 30c at $400. Polar's own published breakeven figures put those tiers ahead from roughly $1,379, $5,634, and $19,048 in monthly sales respectively, which means any SaaS past a few thousand dollars a month pays less here than at Paddle or Lemon Squeezy. Read the surcharges before committing: international cards add 1.5%, disputes cost $15, and payouts carry Stripe's own fees on top. It is also the youngest platform in this list and the least battle-tested on enterprise invoicing, which is precisely the trade you are making for the better rate.

The most operationally mature MoR, and the one to pick when the billing edge cases are the hard part.

Paddle is the safest choice in this category and the one we most often see survive an enterprise procurement review. The published rate is a flat 5% + 50c per checkout transaction with no monthly fee, and that price genuinely includes the whole operation: global tax registration, filing and remittance, subscription billing, fraud and chargeback defense, revenue recovery, and migration help. Where it separates from the cheaper options is the unglamorous machinery, invoicing, purchase orders, and a tax function that has been audited in anger. Two things to know before you sign. First, the published 5% is a list price, and volume discounts are negotiated rather than published, so at scale you should be asking for a rate rather than accepting one. Second, products under $10 and anything needing invoicing fall outside standard pricing into a custom quote, which quietly excludes a lot of low-ticket products from the headline number. Disclosure: BearPlex partners with Paddle, which is why it sits at two rather than one.

MoR bolted onto the payment stack you already run, at the highest published price in the category.

Stripe entered its own competitor's category, and priced it like an add-on rather than an alternative. Managed Payments is a genuine merchant-of-record product covering tax compliance, fraud, disputes, and customer support, and it costs 3.5% per transaction in addition to normal Payments fees. Stack that on the standard 2.9% + $0.30 and you are at roughly 6.4% + $0.30 domestically, before the 1.5% international surcharge or 1% currency conversion. That is the most expensive published option here by a clear margin. It buys one thing the others cannot: you do not migrate. If your subscriptions, webhooks, reporting, and finance reconciliation already run on Stripe, adopting MoR becomes a configuration decision rather than a replatforming project, and the engineering cost of moving billing providers is routinely underestimated. Run the arithmetic honestly. At meaningful volume the spread between 6.4% and Polar's 3.4% is not a rounding error, it is a headcount.

Still a good product at the category rate, now owned by a parent that sells a competing one.

Lemon Squeezy earned its reputation as the friendliest MoR for indie and small SaaS: fast setup, clean checkout, licensing and digital-product handling built in, at 5% + 50c with no monthly fee. Nothing about the product has stopped working. The problem is structural. Stripe acquired Lemon Squeezy in 2024 and has since shipped Managed Payments, its own merchant-of-record product. You are now buying a billing relationship from a company whose parent sells the thing it competes with, and reports of slower onboarding and an unclear roadmap since the acquisition are consistent enough to take seriously. That does not make it a bad choice today. It makes it a choice with a strategic question attached that Paddle and Polar do not carry, and billing is the single hardest system to migrate later. If you pick it, pick it knowing that. Note also that we could not read its pricing page directly on the verification date, so treat its rate as corroborated rather than vendor-confirmed.

A capable enterprise MoR that will not tell you what it costs until you talk to sales.

FastSpring is a long-established merchant of record with real enterprise capability, particularly for software publishers selling globally with localized pricing and complex entitlement models. It has been doing this longer than most of the list. The ranking here is not about capability, it is about transparency: in a category where four competitors publish a rate on a public page, FastSpring publishes none. Independent estimates put the blended cost around 5.9% plus roughly $0.95 per transaction once processing and compliance are bundled, which would make it the most expensive non-Stripe option, but we want to be precise that this is an estimate and not a vendor figure. We are not willing to present a number the vendor did not publish as though it were confirmed. If FastSpring's specific capabilities match something you need, get a written quote and compare it against the published rates above. If your requirements are ordinary SaaS billing, the opacity is a real cost in itself, because you cannot model your own margins without a sales conversation.
