Cost

Web platforms become expensive when they model real business processes: roles, data flows, approvals, integrations, reporting, security, and operations.

Orientation

B2B web platforms usually start from €20k

A simple interface is not the benchmark. What matters is whether the platform can reliably carry workflows, data quality, permissions, approvals, and evidence.

  • €20k+ for bounded portals or internal platforms
  • €50k+ with several roles, data sources, and reporting
  • €100k+ for product platforms, tenancy, or regulated operations
Architecture

Platform cost follows system boundaries

The more existing systems are connected, the more API contracts, data model, error paths, and handover matter. These decisions need to be visible before the build.

  • ERP, CRM, SQL, or cloud data sources
  • Auth, role model, and admin interfaces
  • Deployment, backup, monitoring, and technical documentation
Risk

Standard software often fails on proprietary logic

When processes, calculations, or approvals are unique, workarounds appear in spreadsheets, email, or old tools. A web platform makes sense when this friction becomes more expensive than clean system development.

  • Reduce manual coordination
  • Traceable approval and change history
  • Move business logic from individual knowledge into maintainable software
Included

A platform needs more than login and pages

In B2B platforms, cost comes from roles, states, data quality, error cases, and admin functions. These foundations are less visible than UI, but decide whether the platform works in operation.

  • Auth, roles, permissions, and admin interfaces
  • Data imports, validation, exports, and reporting
  • Deployment, backups, monitoring, and technical documentation by scope
Not included

What often needs separate budgeting

Not every platform scope automatically includes tenancy, complex migration, SLA operations, or data-warehouse integration. These points should be explicitly decided instead of silently assumed.

  • Large historical data migrations or duplicate cleanup
  • Multi-tenant operation, inherited roles, or fine-grained audit trail
  • 24/7 operations, support model, or extensive BI/warehouse layer

FAQ

Common questions on this topic

Web platforms become expensive when they model real business processes: roles, data flows, approvals, integrations, reporting, security, and operations.

01

Can a web platform really start from €20k?

Yes, when scope is clearly bounded: one core workflow, few roles, manageable data sources, and no large migration. Once tenancy, external users, complex approvals, or reporting are added, the corridor rises significantly.

02

What makes a web platform more expensive than a normal website?

A website presents content. A web platform controls processes, data, roles, approvals, error paths, and operations. The effort is therefore in system logic and responsibility, not only the interface.

03

Should operations and hosting be included in the project budget?

Not always fully, but the decision needs to happen early. Deployment, backups, monitoring, access, and handover influence architecture and cost even when ongoing operations later happen internally.
