Monthly, yearly, or your own interval
Free trials on any of them, and tiered plans as variants of a single product.
Recurring revenue without the billing engine
Monthly, yearly, and usage-based plans with trials, proration, and dunning built in. You define the pricing; we run the charges, the invoices, and the tax on every one of them.
What you get
Plans on your terms
Monthly, yearly, or a custom interval. Add free trials, tiered plans, and per-product variants without writing billing logic.
Usage-based metered billing
Charge on consumption from day one. Report usage through the API and we work out what each customer owes.
Upgrades and downgrades with proration
Customers switch plans mid-cycle and the maths is handled. Preview the next renewal before it happens.
Automated payment recovery
Failed charges enter a dunning sequence automatically, so a declined card does not quietly become churn.
Tax on every renewal
As Merchant of Record we calculate, collect, and remit VAT, US sales tax, and GST on the initial charge and every renewal after it, across 27 EU member states and beyond.
Full subscription API
Create, update, pause, cancel, charge one-off amounts, and end trials early — all from the REST API, with webhooks on every state change.
What happens on renewal day
The plan renews, the seats on it are counted, the tax owed where your customer lives is worked out, and a receipt goes out. You set the pricing; the rest of it runs without you.
Seats you can change mid-term
Open an active subscription and edit both the number of seats and the amount per seat.
Upgrades that do the maths
Customers switch plans mid-cycle and the difference is prorated. Preview the next renewal before it charges.
A decline is not a cancellation
Failed charges enter an automated dunning sequence, and a payment.failed webhook fires so your app can react.
Your customers handle the rest themselves
They sign in with a magic link, then change plan, update the card, download invoices, and collect licence keys — without opening a ticket with you.
See it set up, start to finish
Reading about a billing engine only gets you so far. This runs through creating a plan, putting it behind a checkout, and what lands in the dashboard after the first payment.
What sellers say once they have switched
★★★★★ 4.8/5 from 10 reviews on G2 →
Vadim Finayev “We work with quite a few merchants of record, but none comes close to the support and speed of implementation of Fungies. If you want a payment partner that actually gives you the feeling they want to work with you — rather than leaving you on read for three days or randomly restricting your account — you are in the right place.”
David Elliott “I researched the options and Fungies was the best fit for functionality and customisation within a store builder you can connect to your own domain. Taking a small percentage of sales, instead of charging a subscription for every environment and plugin, is refreshing.”
Elnura Abdimanap Kyzy “The platform is user-friendly, integrates easily with APIs and webhooks, and simplifies managing digital products and subscriptions. We were up and running quickly and support has been responsive throughout. Fungies is clearly tailored to the needs of SaaS businesses.”
Francisco Magnone Rienzi “Fungies has been a great partner — fast setup, competitive pricing, and real humans providing quick answers. They are constantly rolling out new features, and I am excited to see what is next.”
