2. Frequently Asked Questions (FAQs)
Answers to the most common questions from eCommerce store owners:
Does ZeroRTO charge per WhatsApp message?
No! ZeroRTO uses a pure "Bring Your Own Key" (BYOK) architecture. You connect your official Meta Cloud API directly. Meta provides 1,000 free service conversations every month, and beyond that, Meta bills you at their standard wholesale rate with zero markup from ZeroRTO.
What happens after the 90-Day VIP Pass ends?
Zero risk! If you choose not to upgrade to an extended enterprise plan, your store smoothly rolls over to the Basic Community Edition automatically. Your store is never locked out, and no hidden credit card charges occur.
Can I switch couriers on the Basic Plan?
On the Basic Community plan, you are entitled to 1 permanently locked courier. If you need multi-carrier failover routing (e.g. running Shiprocket and Delhivery simultaneously), Connected Pro is required.
Will ZeroRTO slow down my WooCommerce admin?
Never. ZeroRTO was architected specifically for speed: database queries use lightweight index lookups, license checks run asynchronously in background cron tasks, and full compatibility with WooCommerce HPOS custom order tables is declared natively.
