Questions?
How does Flowglad process payments?
Currently, Flowglad partners with Stripe to process payments. We are working to diversify providers.
What billing workflows does Flowglad currently support?
You can see a detailed breakdown of our payment workflow support in our docs.
Is Flowglad a merchant of record?
Not yet. We are eager to add merchant of record support soon. Currently we are focused on building better core infrastructure first.
Is Flowglad free for the first $1,000 in volume?
Flowglad doesn't charge for its billing functionality on the first $1,000 moved each month. For credit card transaction, you'll still see a 2.9% + $0.30 per transaction processing fee deducted from that first $1,000. That's the fixed cost of moving money, charged by the card networks and their partners.
What does billing functionality include?
We don’t separate billing from non-billing payments. Our platform is built for usage-based and recurring pricing models, so billing covers: subscription logic, credit tracking, volume tiers, retries, dunning, and account balance management. After $1,000/month, we charge 0.65% for this layer.
If you're only running one-time payments, we still need to charge 0.7%, since we haven’t yet built our own acquiring rails. All our customers rely on us for billing, so splitting pricing would add complexity for little gain.
