A commercial CMS and portal platform widely used in the CIS, valued mainly for its native integration with 1C accounting and its built-in CRM.
Where the business already runs on 1C, that integration is the deciding factor and usually outweighs technical preferences about the platform itself.
We work with Bitrix where the 1C link is the requirement, and we keep the storefront fast by treating the platform as a back office rather than making it responsible for every rendered page.
