FAQ

Answers to common questions about NVCARIA, pricing, and how it works.

What is NVCARIA?

Focused SaaS for two audiences: sellers on eBay and content creators building on YouTube. You connect the accounts you already own and manage the day-to-day work behind them from one console.

Can I subscribe to just one platform?

Yes. Accountant Management is $10 per month and YouTube Operations is $20 per month, billed separately. Subscribe to either or both — each plan unlocks only its own workspace.

Is my data secure?

Access is scoped to the permissions your workflows require, and you control the underlying developer projects. You can disconnect NVCARIA through the original platform whenever you choose.

Can I cancel anytime?

Yes. You can cancel a subscription at any time from your account billing settings. Access continues through the end of the current billing period.
