Teams that look beyond FastSpring tend to want a number they can read before a sales call, or a different split of tasks: some want the tax filing handed over under a published rate, some want direct debit, some want to run the billing engine themselves. The list below mixes merchants of record, European collection tools and engines you configure.
Short answer: Looking for a replacement for FastSpring? Paddle, Twikey and Kill Bill come first in our billing ranking. Ranking order favours the challenger over the household name, so the best-known vendors begin at place 4 where the category allows it. Start with Paddle if you want a merchant of record whose rate you can calculate before you talk to anyone. Each of the 11 alternatives sits in Best Billing Software in 2026 and is described against FastSpring.
Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. How that works.
Built for: Software vendors selling worldwide with local payment methods
Not for: Companies wanting a published price before a sales call

Why buyers look past FastSpring
01
The rate sits behind a quote form
FastSpring's pricing page describes flat-rate pricing set by its team from transaction type and volume, with a quote form that asks for monthly gross volume, transaction count and regional revenue split. It lists no percentage, no per-transaction fee and no plan tiers, and says discounted rates exist for ACH and wire transfers without giving them. Comparing it with a competitor that prints its rate means waiting for an answer first.
02
Tax paperwork follows the product type
The documentation index lists W-8 and W-9 forms, 1099-K reporting and US withholding for downloadable subscription software next to the VAT guide. A seller of desktop software with subscriptions should read those pages before switching, because the withholding rules attach to how the product is delivered and the vendor's own guide is where the detail sits.
03
Your buyer buys from FastSpring
FastSpring's front page says it sells on your behalf, and the checkout, the receipt and the tax invoice come from its side of the relationship. That is the point for a team that wants no VAT filing. It also means the checkout choices (web, popup, embedded, with a component checkout in beta) are the ones listed in its documentation, and any customer relationship you want beyond that has to be arranged through its API and webhooks.

What each one does differently

Paddle
United Kingdom · Published
Paddle prints its price: 5% plus 50 cents per checkout transaction, with no monthly fee, and custom pricing for high volume or products under $10. One platform covers checkout, subscriptions, sales tax and VAT filing, fraud handling, chargebacks and buyer support, and it offers a migration service for sellers arriving from another provider. The pages read give no payout schedule.
Switch from FastSpring if you want a merchant of record whose rate you can calculate before you talk to anyone.
Twikey, a Belgian company, starts at €78 a month for Lite, €145 for Professional and €305 for Premium, with transaction packs of €22.64, €135.90 or €248.48 a month added on top. Lite signs SEPA Core mandates and takes payment links; Professional adds subscriptions, payment plans, recurring cards and PayPal. It collects money on your own account and does not file your VAT.
Switch from FastSpring if your customers are European businesses who pay by direct debit and you are prepared to handle tax yourself.
Kill Bill is Apache 2.0 licensed and can be run free on your own infrastructure through Docker or AWS, with an admin interface called Kaui and plugins for gateways such as Stripe, Adyen, PayPal, Braintree and GoCardless. The managed Aviate edition has a fixed price rather than a percentage of revenue, though the home page gives no amount. Your engineers carry the operations.
Switch from FastSpring if a percentage of every sale is the cost you want gone and you have engineers to run the billing system.
Lemon Squeezy states it is the merchant of record at 5% plus 50 cents per transaction, with no monthly fee on ecommerce. Its pricing page lists 16 payment methods out of the box, VAT and sales tax collection and filing, fraud protection and failed payment recovery. A banner announces a 2026 update with Stripe Managed Payments, so ask what that changes for your account.
Switch from FastSpring if a small product needs a hosted checkout with tax covered, and a fee that fits on one line.
ChargeOver is a Minneapolis recurring billing product that starts at $229 a month, a flat fee and not a share of revenue, moving you up a tier when paying customers exceed your plan. All plans include unlimited invoices, QuickBooks and Xero, HubSpot and Salesforce, an API and a customer portal. Payment methods listed are cards, PayPal and ACH.
Switch from FastSpring if you invoice business customers on a schedule and want a fee that stays put as volume grows.
Zoho Billing publishes two entry plans: Standard at $50 a month ($39 billed annually) and Premium at $100 ($79), each with a 14-day trial. Both cap at 100,000 invoices a year and $1M in annual billed revenue, with 3 or 10 users. That makes it cheap for a small subscription business, and a poor fit once volumes pass those lines.
Switch from FastSpring if a small company wants billing software at a fixed monthly fee and may already use other Zoho products.
Ordway is priced per organisation on request and is configured by finance staff rather than developers. It handles contracts, amendments and the revenue schedules auditors ask for, with pre-built connectors to NetSuite, Sage Intacct, QuickBooks Online and Xero. Expect an implementation project and a named internal owner.
Switch from FastSpring if auditors want revenue schedules and amendments, and a finance team will own the system.
Stripe Billing charges 0.7% of Billing volume pay-as-you-go, or monthly plans on a one-year contract from €500 (up to €80,000 volume) to €4,900 (up to €850,000). Card processing is a separate line, 1.5% plus €0.25 for standard European cards. Basic usage-based features run through the Meters API, up to 100 million events a month.
Switch from FastSpring if you already take payments with Stripe and want invoices and retries in the same system.
BillingPlatform is sold as an enterprise project, quoted per organisation and usually delivered with a partner. Tiered, metered and contract-specific pricing is handled by configuration instead of code. The trade is documentation: a setup nobody wrote down becomes as hard to leave as bespoke software.
Switch from FastSpring if your pricing differs per customer and you have the budget for a proper implementation.
Comarch BSS, from Poland, is a European billing suite built for telecoms and utilities and one of the few here that can be deployed on your own infrastructure. Pricing is quoted, and delivery is consultancy-led with Comarch engineers on the project. The billing module arrives alongside other parts of the suite.
Switch from FastSpring if a regulator or a utility-style business requires billing on infrastructure you control, from a European supplier.
SAP BRIM, from Germany, puts billing and revenue management inside the same ledger as SAP finance. Nothing is self-service: quotes come per organisation and an implementation partner is part of the plan. Module names change between releases.
Switch from FastSpring if SAP already runs your finance and billing should post into it directly.
Paddle: It charges 5% plus 50 cents per checkout transaction with no monthly fee, and covers VAT and sales tax filing.
02
Your customers pay European businesses by direct debit
Twikey: Lite at €78 a month signs SEPA Core mandates, and Professional at €145 adds subscriptions and recurring cards.
03
You would rather run the billing engine yourself
Kill Bill: The core is Apache 2.0 and can be self-hosted free, with gateway plugins for Stripe, Adyen, PayPal and GoCardless.
04
You invoice business customers and want a fee that does not grow with sales
ChargeOver: Plans start at $229 a month, flat, with unlimited invoices on every plan.
05
You already take payments through Stripe
Stripe Billing: Billing is 0.7% pay-as-you-go, with card processing priced separately at 1.5% plus €0.25 for standard European cards.
04
When FastSpring is still the right choice
FastSpring remains a sound choice for a seller of software, games or digital products who wants the tax and the checkout taken off its desk. The pricing page says checkout, subscription management, B2B invoicing and quotes, dashboards, fraud prevention and VAT and sales tax collection and remittance are all inside the flat rate, with no minimum transaction volume. The front page cites 200+ regions, 35+ currencies, 21+ languages and 3,200+ customers, and the documentation covers local methods such as SEPA, Pix, UPI, Alipay and WeChat Pay. If that coverage matches where your buyers are, the quote form is a small price for it.
05
What moving off FastSpring involves
01
Ask for the numbers before you leave
Your FastSpring rate was agreed in conversation, so find the contract and the latest payout statement first. Then set it against the rate printed by a replacement, on your own mix of countries and payment methods.
02
Export subscriptions and licence data
Subscription state, licence keys and customer records live partly in FastSpring's system. Pull them through the REST API and webhooks you already use, and agree how renewals of existing subscribers will be handled, because a new provider usually needs fresh payment authorisation.
03
Rebuild the store, then move in stages
Checkout pages, tax settings, coupons and webhooks all have to be recreated. Put new customers on the new checkout first and let existing subscribers renew on the old one until you trust the reports.

Questions about replacing FastSpring
6 answers
What is the best alternative to FastSpring?
Paddle comes first in our list. It is a merchant of record like FastSpring, and it publishes its price: 5% plus 50 cents per checkout transaction with no monthly fee. Twikey, Kill Bill and Lemon Squeezy follow, each answering a different reason for leaving.
Does FastSpring publish its fees?
Not on the pricing page we read. It describes flat-rate pricing set by its team, says there is no minimum transaction volume, and sends you to a quote form asking for volume, transaction count and regional split.
Which FastSpring alternative is a merchant of record?
Paddle and Lemon Squeezy both describe themselves as taking over tax collection and filing, each at 5% plus 50 cents per transaction. Check the details of each against your product type and your payout needs.
Is there a European alternative to FastSpring?
Twikey is Belgian and Comarch BSS is Polish. Twikey collects by SEPA direct debit from €78 a month and leaves VAT to you, while Comarch is a quoted suite for telecoms and utilities. Paddle is based in the United Kingdom.
Can I stop paying a percentage of every sale?
Yes, with flat-fee products. ChargeOver starts at $229 a month, Zoho Billing at $50 a month ($39 billed annually), and Kill Bill is free to self-host. You then own the tax filing and the payment relationship, which a merchant of record would have carried.
What do I lose when I leave a merchant of record?
The tax filing returns to you or to a new provider. FastSpring's documentation lists W-8, W-9, 1099-K and US withholding topics, so ask an accountant which of those still apply under the new set-up.
