Understanding Per-Site Model

The Per-Site Model is a subscription pricing approach commonly used by documentation platforms, where organizations are billed based on the number of separate documentation sites or projects they maintain. Unlike per-user or per-seat pricing, this model ties costs directly to the documentation infrastructure itself, making it particularly relevant for teams managing multiple products, clients, or documentation portals simultaneously.

Key Features

  • Flat recurring fee applied to each individual documentation site or project
  • Unlimited users or contributors may be allowed within each site, depending on the platform
  • Each site operates as an independent entity with its own settings, branding, and content
  • Costs scale horizontally as new documentation projects are created
  • Often includes tiered pricing where additional sites cost less as volume increases

Benefits for Documentation Teams

  • Predictable budgeting since costs are directly linked to the number of active projects
  • Encourages clean separation of documentation for different products, audiences, or clients
  • Allows large teams to collaborate without per-seat cost penalties
  • Simplifies cost allocation across departments or client accounts
  • Scales naturally with business growth without requiring complex license management
  • Enables agencies and consultancies to pass costs directly to clients on a per-project basis

Common Misconceptions

  • Per-site does not always mean unlimited features — each site may still have content or traffic limits
  • A single site is not always equivalent to a single product; some teams use one site for multiple related products
  • Lower site counts do not necessarily mean lower overall costs if per-site fees are high
  • This model is not always cheaper than per-user pricing for small teams managing many sites
  • Archiving or deactivating a site may still incur charges depending on the platform's billing policies

Real-World Documentation Use Cases

SaaS Company Managing Multiple Product Documentation Portals

Problem

A growing SaaS company has launched three separate products, each requiring distinct documentation with unique branding, navigation, and content. Managing them under a single portal creates confusion for users and makes version control difficult.

Solution

Adopt a Per-Site Model to create isolated documentation environments for each product, ensuring clean separation of content, branding, and access controls without paying extra per contributor.

Implementation

1. Audit existing documentation to identify logical site boundaries per product. 2. Create a dedicated site for each product on the platform. 3. Assign product-specific writers and editors to each site. 4. Configure unique domains or subdomains per site (e.g., docs-productA.company.com). 5. Set up separate analytics tracking per site to monitor engagement. 6. Review monthly costs as new products launch and budget accordingly.

Expected Outcome

Each product team owns their documentation portal, user confusion is reduced, and the company pays a predictable flat fee per site regardless of how many writers contribute to each project.

Documentation Agency Billing Clients Per Project

Problem

A documentation consultancy manages documentation for 10 different clients. Sharing a single platform account creates privacy risks, makes client-specific branding impossible, and complicates invoicing.

Solution

Use the Per-Site Model to create one site per client, enabling isolated environments that can be white-labeled and directly billed back to each client as a line item.

Implementation

1. Create a new documentation site for each client onboarded. 2. Apply client-specific branding, logos, and domain configurations per site. 3. Invite only the relevant client stakeholders to each site. 4. Calculate per-site platform costs into client project quotes. 5. Archive or delete sites when client contracts end to control costs. 6. Maintain a master account dashboard to monitor all active client sites.

Expected Outcome

Clients receive fully isolated, branded documentation portals, the agency maintains clean separation of work, and costs are transparently passed through to clients on a per-project basis.

Enterprise Team Separating Internal and External Documentation

Problem

An enterprise organization needs to maintain both customer-facing product documentation and internal employee knowledge bases. Mixing these in one site creates access control challenges and inappropriate content exposure.

Solution

Leverage the Per-Site Model to create separate sites for external documentation and internal wikis, each with distinct access permissions, authentication methods, and content strategies.

Implementation

1. Define the content categories requiring separation (public docs, internal SOPs, partner portals). 2. Provision a dedicated site for each category. 3. Configure public access for customer-facing sites and SSO/private access for internal sites. 4. Assign dedicated content owners and editors per site. 5. Establish a governance policy for when new sites should be created versus extending existing ones. 6. Review site usage quarterly to consolidate or expand as needed.

Expected Outcome

Sensitive internal documentation remains secure and separate from public content, access management is simplified, and the organization gains clear cost visibility per documentation function.

Open Source Project Maintaining Versioned Documentation Sites

Problem

An open source project needs to maintain active documentation for three major software versions simultaneously. Keeping all versions in one site creates navigation complexity and risks outdated content being served to users on older versions.

Solution

Use the Per-Site Model to host each major version as a standalone documentation site, allowing independent update cycles and clear URL structures per version.

Implementation

1. Identify the active software versions requiring dedicated documentation. 2. Create a separate site per major version (e.g., v1-docs, v2-docs, v3-docs). 3. Migrate or clone existing documentation into the appropriate versioned site. 4. Set up a landing page that routes users to the correct version based on their selection. 5. Assign maintainers responsible for keeping each version's docs current. 6. Deprecate and archive older version sites when support ends to reduce costs.

Expected Outcome

Users always access accurate, version-specific documentation without confusion, maintainers can update each version independently, and the project controls costs by retiring old sites as versions are deprecated.

Best Practices

✓ Audit and Define Clear Site Boundaries Before Provisioning

Before creating new documentation sites under a Per-Site Model, establish clear criteria for what constitutes a separate site. Without defined boundaries, teams often create redundant sites that inflate costs unnecessarily or, conversely, cram too much content into one site causing navigation problems.

✓ Do: Create a site governance document that defines when a new site is warranted — such as distinct product lines, separate audiences, unique branding requirements, or isolated access controls. Review this policy quarterly.
✗ Don't: Avoid creating a new site for every minor documentation project or sub-feature. Overprovisioning sites without clear justification leads to uncontrolled cost growth and fragmented content that is hard to maintain.

✓ Build a Site Cost Allocation Model for Budget Transparency

Since the Per-Site Model ties costs directly to the number of active sites, organizations should map each site to a cost center, team, or client account. This ensures documentation costs are visible and accountable across the business rather than buried in a single IT or marketing budget line.

✓ Do: Maintain a spreadsheet or internal dashboard that lists every active site, its owner, its business purpose, and its monthly cost contribution. Share this with finance and department heads during budget cycles.
✗ Don't: Do not allow documentation sites to be created without an assigned owner and cost center. Orphaned sites with no clear owner continue to accrue costs without delivering value.

✓ Regularly Review and Archive Inactive Sites

Documentation sites for discontinued products, completed projects, or deprecated software versions can accumulate over time, silently driving up monthly costs under a Per-Site Model. Establishing a regular review cycle ensures you only pay for sites that are actively serving users.

✓ Do: Schedule a quarterly site audit to review traffic analytics, last-edit dates, and business relevance for each site. Archive or delete sites that have had no meaningful traffic or updates in 90+ days.
✗ Don't: Do not keep legacy sites active indefinitely out of convenience. Even low-traffic sites carry the same per-site fee, and outdated documentation can mislead users who stumble upon it.

✓ Negotiate Volume Discounts as Your Site Portfolio Grows

Many documentation platforms offering a Per-Site Model provide volume-based pricing tiers where the per-site cost decreases as the number of sites increases. Organizations managing five or more sites should proactively negotiate these discounts rather than waiting for the platform to offer them.

✓ Do: Track your total site count and projected growth. When approaching a new pricing tier, contact the platform vendor to negotiate a volume discount or annual commitment deal that reduces the effective per-site rate.
✗ Don't: Do not assume the listed per-site price is fixed. Vendors are typically willing to negotiate custom pricing for customers with large site portfolios or long-term commitments, but you must initiate the conversation.

✓ Standardize Site Templates to Reduce Setup Time and Costs

Under a Per-Site Model, teams frequently create new sites as products or clients are added. Without standardized templates, each new site requires significant setup time for navigation structure, branding, and boilerplate content, which indirectly increases the cost of provisioning each site.

✓ Do: Develop a master site template that includes pre-configured navigation structures, branded themes, standard page templates (Getting Started, API Reference, Changelog), and placeholder content. Clone this template whenever a new site is provisioned.
✗ Don't: Do not build each new documentation site from scratch. Inconsistent site structures across your portfolio make cross-site maintenance harder and create a disjointed user experience for customers who interact with multiple products.
