SaaS Payment Gateway FAQ

How does MAGNETPAY handle SaaS subscription billing?

MAGNETPAY provides a complete subscription management engine. You define plans with pricing tiers, billing intervals (monthly, quarterly, annual), and trial periods. Our system handles recurring charge attempts, proration for plan changes, and automatic invoice generation. Webhooks notify your application of every billing event so you can provision or deprovision access in real time.

Does MAGNETPAY support usage-based and metered billing?

Yes. Our metered billing API lets you report usage events throughout the billing period. At the end of each cycle, MAGNETPAY calculates the total usage, applies your pricing model (per-unit, tiered, volume, or package), and generates the invoice automatically. This is ideal for API platforms, cloud infrastructure, and any SaaS that charges based on consumption.

What dunning and retry strategies are available?

MAGNETPAY includes intelligent dunning automation. When a payment fails, our system retries at optimized intervals using smart scheduling that considers the failure reason. We support configurable retry cadences, automatic card updater integration, pre-dunning notifications, and graceful degradation flows that let you downgrade access before cancellation.

Can I accept SaaS payments in multiple currencies?

Absolutely. MAGNETPAY supports 30+ currencies with automatic FX conversion. You can price your SaaS plans in local currencies for each market, improving conversion rates by 10-20% compared to forcing customers to pay in USD. Settlement happens in your preferred currency regardless of what your customers pay in.

How do upgrade and downgrade flows work?

Plan changes are handled with automatic proration. When a customer upgrades mid-cycle, we calculate the pro-rated amount for the remaining period and charge the difference immediately or add it to the next invoice. Downgrades generate a credit that is applied to future invoices. You control the behavior via API parameters.
