Pros & Cons
Lemon Squeezy
Pros
No monthly fee, only pay a percentage on actual sales
Removes the burden of registering for sales tax and VAT in multiple countries
Fast setup, popular with solo developers and small SaaS teams
Now backed by Stripe's payments infrastructure post-acquisition
Built-in licensing and affiliate tools reduce the need for extra integrations
Cons
The flat $0.50 per-transaction fee hurts margins on low-priced products
Less checkout customization than building directly on Stripe
Long-term roadmap is uncertain as Stripe develops its own Stripe Managed Payments product
Extra surcharges stack for PayPal, international sales, subscriptions and affiliates
Payout schedules and reserve holds can feel restrictive for new sellers
invoice-api
Pros
Covers a wide range of EU e-invoice formats (XRechnung, ZUGFeRD, Factur-X, FatturaPA, Peppol) from a single API
Free tier with no credit card required, plus a live API playground for testing before committing
Pre-built integrations for major shop platforms (Shopify, WooCommerce, Shopware, Magento, PrestaShop, JTL-Shop) and automation tools (n8n, Zapier, Make, Airtable, HubSpot)
Includes GoBD-compliant archiving with 10-year retention, addressing a compliance need many teams would otherwise build separately
Transparent, published self-serve pricing with a 14-day trial on paid tiers
Cons
Free tier is limited to 20 API calls total, which only covers basic evaluation, not real usage
Paid tiers are metered by API call volume, so cost can scale quickly for high-volume invoicing
Site content is presented primarily in German with an English toggle, and depth of English documentation may lag the German version
As a developer API rather than an end-user application, it requires engineering effort to integrate rather than being usable out of the box by non-technical teams
