Key Takeaways

  • First decide: processor or merchant of record. A processor (Stripe Billing) is cheaper per charge but leaves tax compliance to you. A merchant of record (Paddle, Lemon Squeezy, Polar, Stripe Managed Payments) handles it for a higher fee.
  • On a $20 US card charge, fees range from about $1.02 to $1.72. That is Stripe Billing at the low end and Stripe Managed Payments with Billing at the high end, by our arithmetic from published rates.
  • Stripe Billing is the default for most. Low published fees, Smart Retries on by default for new accounts, and add-on tax calculation through Stripe Tax.
  • Merchants of record trade margin for time. If you sell to consumers in many countries and don’t want VAT registrations, the extra few percent can be worth it.
  • Chargebee is a billing layer, not a processor. It sits on top of payment gateways and suits businesses whose billing rules have outgrown the basics.

Every subscription app needs something to charge cards every month, retry the ones that fail, send receipts and let customers cancel. The bigger decision hiding inside that choice is tax: with a standard payment processor, your business is the seller and handles sales tax and VAT; with a merchant of record, the provider is the seller and handles it for you, for a higher fee. This list compares six options a small software business is likely to consider in 2026, using each provider’s own pricing page and documentation. We rank them for one reader: a small team or solo founder selling a web subscription, mostly to individuals and small businesses, in more than one country.

Processor or merchant of record: the decision that matters most

Before comparing brands, decide which model you want. It affects fees, tax and who your customer sees on their statement.

Payment processor

You are the seller. The processor moves money, runs subscriptions and may calculate tax, but registering and filing sales tax or VAT is your responsibility. Fees are lower. Stripe Billing is the common example.

Merchant of record (MoR)

The provider buys from you and resells to your customer, so it is the legal seller and takes on tax collection and filing, and usually fraud and disputes. Fees are higher, and the provider’s name or yours may appear on statements depending on the product. Paddle, Lemon Squeezy, Polar and Stripe Managed Payments work this way.

A rule of thumb

If most customers are in one country and you understand its tax rules, a processor is usually enough. If you sell to consumers in many countries, an MoR can save registrations and filings. Our sales tax and VAT guide explains the rules in more detail. This is general information, not tax advice.

1. Stripe Billing

Best for: most small subscription businesses, particularly those selling mainly in the US or to businesses.

What it does well

Stripe Billing runs subscriptions, invoices, trials and upgrades on top of Stripe Payments. Revenue recovery is strong out of the box: Stripe’s docs say Smart Retries is enabled by default for new accounts with up to 8 retries within 2 weeks, and you can turn on emails for failed payments, expiring cards, renewals and trial endings. The customer portal lets subscribers update cards, switch plans, pause, cancel and download invoices. Payment Links let you sell a subscription without code.

What to watch

You are the seller, so tax is yours. Stripe Tax can calculate and collect it (0.5% per transaction where you’re registered on no-code integrations), but registration and filing remain your job unless you buy a Tax Complete plan, from $90 a month on a one-year contract. Integrating subscriptions into your own app means handling webhooks or using a builder that does.

Price

2.9% + 30¢ per successful domestic card charge in the US, +1.5% for international cards, +1% for currency conversion, and 0.7% of billing volume for Billing on pay-as-you-go. A $20 US card charge costs about $1.02 in total.

2. Paddle

Best for: software sellers with many consumer customers abroad who want one fee that covers tax compliance.

What it does well

Paddle positions itself as your merchant of record. Its pricing page says it collects the applicable tax, tracks filing deadlines and submits sales tax returns and payments for you, and includes checkout, subscription billing, fraud protection, chargeback handling and buyer support, with no monthly fees.

What to watch

The fee is higher than a processor’s, and Paddle directs sellers of products under $10 to contact it for bespoke pricing. As with any merchant of record, check that it accepts your type of product before you build checkout around it.

Price

5% + 50¢ per checkout transaction on pay-as-you-go. A $20 charge costs $1.50.

3. Stripe Managed Payments

Best for: eligible digital product sellers who like Stripe’s tools but want Stripe to be the merchant of record.

What it does well

Stripe’s docs describe Managed Payments as its merchant of record solution for digital products such as SaaS, software and digital content. It handles sales tax, VAT and GST compliance in more than 80 countries, plus fraud prevention, dispute management and transaction-level customer support. Subscriptions run on Stripe Billing, and it works with Checkout and Payment Links.

What to watch

Eligibility is narrower than standard Stripe. Your business must be in a supported location (the docs list the US, Canada, much of Europe, Australia, Hong Kong, Japan and Singapore), products must be fully automated digital goods with an eligible tax code, and Stripe runs an eligibility review. It doesn’t support Connect, embedded payment components, or creating subscriptions outside Checkout or Payment Links. Lemon Squeezy’s January 2026 update describes Managed Payments as the path it intends to offer its users.

Price

Stripe’s pricing page lists 3.5% per successful Managed Payments transaction, in addition to payments fees. By our arithmetic, a $20 US card charge costs $0.88 + $0.70 = $1.58, or about $1.72 with Billing’s 0.7% if that applies to your subscriptions.

4. Polar

Best for: developers and small software businesses who want a merchant of record with a choice between per-transaction and monthly-plan pricing.

What it does well

Polar acts as merchant of record and says it handles international tax compliance, fraud and dispute prevention. Its pricing lets you swap part of the per-transaction premium for a monthly fee as you grow, which can lower the effective rate at higher volumes.

What to watch

Non-US cards add 1.5%. Organizations created before May 27, 2026 may be on an Early Member plan with a separate 0.5% subscription fee. Compare the monthly plan fees against your volume before switching tiers.

Price

Per transaction: Starter 5% + 50¢, Pro 3.8% + 40¢, Growth 3.6% + 35¢, Scale 3.4% + 30¢, plus each paid plan’s monthly fee shown on Polar’s pricing page. A $20 US charge on Starter costs $1.50.

5. Lemon Squeezy

Best for: existing Lemon Squeezy sellers and creators of simple digital products.

What it does well

Lemon Squeezy is a merchant of record that handles tax calculation, collection and filing, with checkout, subscriptions (weekly, monthly, yearly) and a range of payment methods including PayPal.

What to watch

Its pricing FAQ says small additional fees may apply in some cases, and transactions outside the US may carry extra fees. Lemon Squeezy is part of Stripe, and its January 2026 update from the CEO says the team has been building Stripe Managed Payments and aims to give users an easy way to migrate there; it sets no deadline. If you are starting fresh, weigh that direction.

Price

5% + 50¢ per transaction, with possible additional fees. A $20 charge costs at least $1.50.

6. Chargebee

Best for: businesses with billing rules that have outgrown a processor’s defaults, such as complex usage pricing, many plans or several payment gateways.

What it does well

Chargebee is subscription billing software that connects to more than 40 payment gateways, so you can keep Stripe (or another gateway) for payments and use Chargebee for plans, invoicing, usage and revenue operations.

What to watch

It is not a payment processor or merchant of record, so you pay gateway fees on top and tax remains yours (or your gateway’s tax tool’s). For a solo founder with one or two plans, it adds a layer you may not need yet.

Price

Chargebee’s pricing page shows a self-serve Billing plan called Flow, with a calculator based on monthly invoicing volume that displays $0 + 0.80% and $99 + 0.65% options, and custom Enterprise pricing. Check the calculator for your volume.

How to choose

Four questions settle it for most small businesses.

  • Where are your customers? Mostly one country: start with Stripe Billing. Consumers in many countries: consider an MoR.
  • Are your customers businesses? B2B sales often have simpler VAT handling with a valid tax ID, which favors a processor.
  • How much time will you spend on tax? If the honest answer is “none”, the MoR premium buys that.
  • Is your product eligible? MoRs accept only certain digital products; check before you build checkout around one.

Common mistakes

These come up most with first subscription businesses.

  • Comparing only the headline rate and ignoring tax compliance, which an MoR includes.
  • Choosing an MoR, then building a product it won’t accept (services with human work, physical goods).
  • Forgetting international card and currency conversion fees when modelling margin.
  • Leaving failed-payment emails and retries switched off.
  • Building a custom billing layer before you have more than a couple of plans.
  • Picking a platform without checking how you would migrate subscribers away later.

A note for people building on Floot

Floot is an app builder, not a payment processor. If you build your subscription app on Floot, Floot Payments handles checkout and subscriptions inside the app and pays out via Stripe, so you don’t set up Stripe products or webhooks yourself. It does not handle sales tax or VAT, so the processor-versus-MoR questions above still apply to your tax planning.

Frequently Asked Questions

What is the best payment platform for a small SaaS?

For most small subscription businesses, Stripe Billing: low published fees, built-in retries and reminder emails, and optional tax calculation. If you sell to consumers in many countries and want tax handled for you, a merchant of record such as Paddle or Stripe Managed Payments is worth the higher fee.

What is a merchant of record?

A company that legally sells your product to the customer on your behalf, taking on sales tax and VAT collection and filing, and usually fraud and disputes. You receive the proceeds minus its fee.

Is Paddle cheaper than Stripe?

Per charge, no: on $20, Paddle’s listed 5% + 50¢ is $1.50 against about $1.02 for Stripe Billing. Paddle includes tax compliance, which Stripe Billing leaves to you, so compare total cost including your time and any tax software.

Is Lemon Squeezy shutting down?

Its January 2026 update doesn’t announce a shutdown. It says the team has been building Stripe Managed Payments and intends to give Lemon Squeezy users an easy way to migrate, without setting a deadline.

Can I switch payment platforms later?

Yes, but moving active subscriptions means moving saved payment details, which depends on both providers’ migration support. It is easier early, with few subscribers, than later.

Do I need Chargebee if I use Stripe?

Usually not at the start. Stripe Billing covers standard plans, trials, upgrades and dunning. Chargebee adds value when billing rules get complex or you use several gateways.
