GrandNode lets you run one shop, a dozen regional storefronts, or a full marketplace from a single installation, with a back office for every role involved. Each store gets its own domain, theme, currencies, languages, and settings, and a store manager panel limits staff to the catalog, orders, and customers of their own store. Outside sellers join through a vendor panel where they manage their own products and orders. The catalog handles attributes and combinations, bundles, grouped items, downloads, date-based reservations, and auctions. B2B selling adds customer groups, tier prices, sales employees, and approvals. Checkout accepts payments through plugins such as Stripe Checkout, Braintree, and cash on delivery, with shipping by fixed rate, weight, or pickup point and tax rules by country, state, or zip code. Marketing tools include coupon codes, discount rules, loyalty points, gift vouchers, customer segments, newsletter campaigns, and push notifications. Clean URLs, sitemaps, and structured data with price and availability help search engines read your products. Pages, blog posts, news, and sliders cover content, and a REST API serves headless storefronts and ERP or CRM integrations. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GPL-3.0 licensed.
