You pay what your church uses

No subscription and no minimum: each month's bill is the hours your servers ran, by how strong they were, your files by their gigabytes, and a small share of the service itself (sign-in, email, backups). The Costs tab shows the month as it goes, line by line.

Fast mixes a service in half the time and costs a little over twice as much an hour. Prices in euros, before VAT where it applies. A job that fails is never charged.
