Each paid license can be activated on up to 3 different WordPress installations. This is ideal if you run multiple restaurant locations or manage client websites. Need more than 3 sites? Simply purchase additional licenses.

After payment is confirmed, your license key is automatically generated and emailed within seconds — no manual processing. You’ll receive the plugin ZIP file, your license key (format: RBP-1Y-XXXXXX-XXXXXXXX), and a link to the full setup guide in one email.

Yes. You can upgrade to a higher-tier plan at any time by purchasing the new plan. The new license key replaces the old one on your site. Contact support@digitalzila.com if you need help with the transition.

If you’re not satisfied within 30 days of purchase, email us at support@digitalzila.com for a full refund — no questions asked. The guarantee applies to all paid plans: Starter, Professional, Business, and Annual.

You can purchase JavisTab using Stripe (Visa / Mastercard / international cards), PayPal, or VietQR bank transfer (Vietnam). All transactions are processed securely.

Yes — all plans include automatic updates for the full license duration. Updates appear directly in your WordPress admin under Plugins, exactly like any other WordPress plugin. No manual ZIP uploads needed.

Absolutely. JavisTab was built specifically with Vietnamese restaurants in mind: VietQR bank transfer, Zalo OA messaging, ZNS notifications, OnePay Vietnam, full Vietnamese language, and VND currency support — features no generic booking plugin provides.

Yes. Switch the capacity mode to by_guests to limit total guests per slot instead of counting by tables. Create buffet-tier service packages (e.g. “Buffet Standard 350,000đ/person”) selectable at booking time — price is automatically calculated by guest count.

Zalo OA messaging, Zalo Chat Widget, and SMS via Twilio are included from the Starter plan ($19.9/30 days) and above. The Free Trial includes email confirmations only. You’ll need a free Zalo Official Account and an OA Access Token from the Zalo developer portal.

REST API access (available in Professional plan and above) lets you connect JavisTab to your POS system, custom management dashboard, or third-party integrations. You can read and manage bookings, customer data, and table availability via standard HTTP endpoints — no plugin dependency on your front end.

JavisTab requires WordPress 5.8+, PHP 7.4+, and MySQL 5.7+, plus an active internet connection for license verification. It works with any WordPress theme and does not require WooCommerce or any page builders.
