How to Run One Knowledge Base Across Multiple Brands
To run one knowledge base across multiple brands, use a platform that separates your content library from your portal presentation: create one account, add a branded portal per brand with its own domain and theme, decide which articles are shared versus brand-specific, and manage all portals from a single admin panel. Multibase supports this natively with flat pricing — a right-sized admin count and per-portal custom domains on every paid plan, with no per-brand tax.
Step 1: Start from one account, not one account per brand
The foundation is a platform where the account and the brand are separate concepts. Sign up once, and treat each brand as a portal within that account rather than a new subscription. This is what makes centralized administration possible — one team, one billing relationship, one set of user permissions governing every portal.
Step 2: Create a portal per brand with its own domain and theme
For each brand, create a portal and configure its custom domain (help.brandname.com via CNAME), logo, color scheme, and fonts. Because portals are independent, readers never see cross-brand branding or a shared 'powered by' footer — each portal looks like a standalone product built for that brand alone.
Step 3: Decide what content is shared versus brand-specific
Not everything needs to be duplicated. Policies, integrations, or platform-wide features that apply across brands can be written once and published to multiple portals; brand-specific product differences get their own articles. This is where a real multi-brand platform saves the most time versus running fully separate tools — updates to shared content apply everywhere at once instead of requiring manual edits per brand.
Step 4: Manage access and analytics centrally
Add team members once at the account level and assign portal-level permissions as needed, rather than provisioning separate logins per brand. Track article performance, search gaps, and AI answer accuracy per portal from one dashboard, so a documentation lead overseeing ten brands isn't logging into ten separate tools to see how each one is performing.
Frequently asked questions
Do I need a separate account for each brand?
No. Platforms built for multi-brand documentation, like Multibase, let one account manage multiple branded portals — each with its own domain and theme — without a separate subscription per brand.
Can I reuse the same articles across brands?
Yes. Content that applies to every brand can be published to multiple portals from a single source, while brand-specific content stays scoped to its own portal.
How many brands can one knowledge base support?
It depends on the plan: Multibase includes 3 portals on Growth ($49/mo), 10 on Scale ($149/mo), and unlimited portals on Enterprise ($399/mo), so the practical limit is your subscription tier, not the platform itself.
