Yes. Price List PRO ships as a single download that runs on Joomla 4, Joomla 5 and Joomla 6. The component follows Joomla's namespacing and service provider patterns, so an update to the next major Joomla version is just a regular extension update for you.

Older versions for Joomla 3 are still available in the customer area for legacy sites, but they no longer receive feature updates.

Yes, that is the entire point. One PRO license covers unlimited installations. Build for ten clients, install on ten sites, get updates on all of them. There is no domain registration, no machine ID check and no email when you migrate a site to a new server.

This is why agencies and freelancers tend to skip the single PRO and go straight for the Bundle: the same logic applies to every other extension in it.

The PRO version uses Joomla's native ACL (Access Control Levels). You set an access level per category, per item or per custom field, and visitors only see the prices that match their user group. 

Everything is configured in the standard Joomla way, so it integrates with whatever login or registration setup you already have.

Yes. Price List uses Joomla's standard language packs, which means each item, category and column header can be translated separately. Ships with Dutch, English, German, French, Spanish, Italian and more out of the box.

You can publish a different price list per language without duplicating items, or run a fully separate price list per language site if that fits your setup better.

The component keeps working. Forever. PRO is not a SaaS, there is no kill switch. After 12 months you simply stop receiving new versions and email support unless you renew.

Renewals are 75% of the original price as a thank-you for sticking around.
