Understand the no-subscription model

An issue with your system?

Most systems don’t break by chance. They become unstable over time due to accumulated technical decisions.

  • 500, 403, 404 errors
  • Broken or inconsistent redirects
  • PHP bugs or unstable behavior
  • .htaccess conflicts or incorrect routing
  • Permissions issues or server structure problems

My role is not just to fix the symptom, but to identify the root cause and stabilize the system.

Factur-X Invoice Generation (Comfort Profile)

The service enables automated generation of structured invoices from standardized CSV files, producing PDF documents that embed XML data compliant with the Factur-X format (Comfort profile, EN16931 structured standard).

Palks Studio provides the technical processing infrastructure, data structuring, document generation and organization of deliverables as structured archives, ready to be sent, uploaded to platforms or stored by the client according to their own processes.

Billing and the service relationship are handled directly by Palks Studio.

The transmission of invoices to submission portals or e-invoicing platforms remains the responsibility of the client, in accordance with their own obligations and internal tools.

Factur-X EN16931 engine integration for existing systems

Integration of a Factur-X EN16931 generation engine directly into your existing invoicing system (ERP, business software, internal tools).

The goal is not to replace your system, but to make it compliant with the Factur-X format, with generation of PDF/A-3 invoices including structured XML data.

The integration is deployed on your infrastructure, without SaaS or external dependencies, using your existing data and workflows.

Designed for companies, software vendors and organizations requiring compliance or integration within an existing system.

Indicative pricing

Services are billed in three ways: indicative daily rate of €500 / day, fixed-price scope or project-based pricing depending on the mission.

Each mission — invoicing, technical systems, server work or deployment — is reviewed through a short written analysis to clearly define the scope and associated estimate.
