Pricing
Holnix does not publish pricing on its website; prospective publishers and bookstores must contact the company directly for plan and cost details.
Holnix is a metadata management platform built for book publishers and the bookstores and distributors that sell their titles. Publishers upload their catalog data as ONIX files, and Holnix automatically processes and distributes that metadata to every connected retail channel, keeping titles, pricing, and availability synchronized in real time. Bookstores and distributors can browse and filter the resulting catalog by publisher, ISBN, or publication date instead of re-entering data by hand. Holnix also ships plugins for Shopify, WooCommerce, and Magento (plus a standalone Holnix App) so retailers can pull publisher catalogs directly into their existing e-commerce storefronts. The company is based in Miami, Florida, and its site and customer base skew toward Spanish-language and Christian/religious publishers such as Unilit, Portavoz, and CLIE, alongside other publishing houses.
