RenderAI cut its payment integration from days to minutes.

RenderAI sells usage tokens for image generation across three plans. Before Fungies, the payment side was largely manual, which was slow and error-prone — it delayed revenue and made onboarding new customers harder than it needed to be.

The founder wanted a reliable way to handle subscriptions, a checkout that looked like RenderAI rather than a third party, and an integration that would not take weeks. Building that from scratch is usually a matter of weeks or months.

The two teams worked through what RenderAI actually needed, then configured the checkout from templates with the Start, Monthly Pro, and Professional plans wired in. After a round of testing, the new checkout went live and customers could buy tokens straight away.

Webhooks pass the user ID back into the app, so a purchase immediately becomes usable credit in the right account without anyone reconciling anything by hand.

As Merchant of Record, Fungies handles payments globally and takes on the compliance that comes with them. Our team was available throughout the integration.

RenderAI began collecting payments the same day, which meant meeting demand that already existed rather than asking people to wait. Choosing a plan and paying for it is now a short, clear flow.

Billing cycles and subscription changes are automated, so the administrative load has largely gone and the team is back to working on the product itself.
