About FastSpring

FastSpring is a merchant of record (MoR) for SaaS and digital product companies, handling global payments, tax compliance, and subscription management. Popular with software companies selling internationally, FastSpring manages the entire billing relationship including dunning communications.

Built-in dunning: As the merchant of record, FastSpring handles dunning internally with automatic retries and email notifications. They manage the customer communication from their platform, sending payment failure emails under the FastSpring billing brand. Merchants have limited ability to customize the recovery process.

Why FastSpring's Native Dunning Falls Short

MoR controls the dunning experience

FastSpring owns the billing relationship and controls what recovery emails say, when they're sent, and how the customer experience feels. Your input is limited.

FastSpring-branded communication

Recovery emails come from FastSpring, not your brand. For SaaS companies building a direct customer relationship, this creates a disconnect.

No voice or SMS recovery

FastSpring's recovery is email and retry only. For high-value software subscriptions, the lack of voice outreach is a missed opportunity.

Limited customization

You can't A/B test recovery messaging, segment customers by value, or create custom escalation paths within FastSpring's dunning system.

How Rezoki Supercharges FastSpring

Branded recovery alongside FastSpring

While FastSpring handles the transactional billing emails, Rezoki sends branded recovery messages from your company — emails and calls your customers actually recognize.

AI voice for SaaS subscriptions

For software subscriptions with high annual value, Rezoki's AI voice calls resolve payment issues that FastSpring's automated emails miss.

Customer intelligence

Understand why your FastSpring payments fail, which customer segments are most at risk, and optimize your approach based on real recovery data.

Global SaaS optimization

FastSpring serves global SaaS sellers. Rezoki optimizes recovery per region, timezone, and customer locale — sending communications when and how they'll be most effective.

Frequently Asked Questions

Can I do my own dunning if FastSpring is my MoR?+
Yes. While FastSpring handles the official billing communication, you can always communicate with your own customers about their subscription status. Rezoki makes this easy with AI-powered branded outreach.
Won't it confuse customers to hear from both FastSpring and Rezoki?+
Rezoki sends emails from your company, not from "Rezoki." Customers get a helpful message from the software they use, separate from FastSpring's billing notifications. It feels natural and helpful.
Is the FastSpring integration available now?+
Stripe integration is available now. FastSpring integration is coming soon — join the waitlist to be notified when it launches and get early access.
Does Rezoki work with FastSpring's popup storefront?+
Yes. Rezoki can include links to FastSpring's account management page in recovery emails, letting customers update their payment method through FastSpring's existing infrastructure.
How does pricing work for AI recovery on top of FastSpring's MoR fees?+
Rezoki charges a percentage of successfully recovered revenue only. Combined with FastSpring's MoR fees, the math still works strongly in your favor since recovered revenue would otherwise be completely lost.
