Frequently asked questions

FAQ

Which payment gateway is best for me?

It depends on your market: MercadoPago for LATAM (high local adoption and local payment methods), Stripe for international payments and SaaS, Wise for multi-currency transfers. We often integrate more than one and route payments based on the customer.

Do you handle subscriptions and recurring payments?

Yes. We implement plans, free trials, upgrades/downgrades, and retry logic for failed payments, with billing logic connected to your product.

Does this work for a marketplace with multiple sellers?

Yes. With split payments, we collect from the buyer and automatically distribute to each seller, deducting your commission.

How do you ensure a payment is confirmed correctly?

We use idempotent webhooks: the transaction state is confirmed from the gateway side, not the browser, to avoid lost or duplicate payments.
