Autonomous backend systems, server deployment and e-invoicing

Palks Studio builds backend systems from scratch — complete Factur-X EN16931 invoicing, workflow automation and deployment on standard hosting. Server troubleshooting, PHP bug fixes, Apache configuration and site recovery after incidents. No framework, no CMS, no SaaS subscription. PHP, JavaScript, Python. Bilingual FR/EN.

Palks Studio designs and deploys technical systems on your server, built to simplify real operational processes while remaining simple, understandable and maintainable over time.

A different approach, more reliable and more robust: no SaaS, no external dependencies, no subscription.
Result: less maintenance, fewer risks and controlled long-term costs.

• Server integrations and adjustments
• Complete e-invoicing system (quotes, invoices, payments, exports)
• Factur-X EN16931 engine (integration into your existing system)
• Factur-X batch service (monthly generation from CSV)
• Recruitment system with automatic scoring and recruiter dashboard

No imposed framework, no CMS, no database. Native PHP, JavaScript, Python. Apache, o2switch or equivalent.

Once deployed, the system runs autonomously.

Who is it for?

• Independent professionals and small businesses
• SMBs and growing companies
• Business software publishers
• Companies needing to design, stabilize or evolve a backend system

500 errors, unresponsive scripts, unstable automations, difficult-to-maintain dependencies or repeated manual processing: these issues often appear at the level of tools, integrations or the backend system structure itself.

Over time, some architectures become difficult to evolve: accumulation of patches, external dependencies, scattered critical processes or fragile business logic.

Understanding these situations often makes it possible to stabilize an existing system, simplify certain workflows or reduce technical complexity without starting from scratch. See backend problems.

Complete e-invoicing system: deployed on your hosting, no subscription

A complete system to manage quotes, invoices, payments and archiving without external software or subscription.

Installed directly on your hosting, it runs independently with a clear structure, controlled data and full traceability.

Designed for freelancers, artisans and small businesses looking to keep full control over their invoicing with a system deployed directly on their own hosting.

Structured application form, automatic candidate scoring, recruiter dashboard and multi-campaign management, directly deployed on your hosting environment.

View the system

Create a clean, complete and structured quote, ready to send in seconds. Automatic legal mentions based on the client country, with no account, no server and no transmitted data.

Access the tool

Test the generation of a Factur-X EN16931 compliant invoice from a simple form.
The generated PDF includes a compliant structured XML (XSD, Schematron and PDF/A-3), identical to the one used in production.
This demonstration makes it possible to verify Factur-X EN16931 compliance using the real engine deployed in production.
Automatic legal mentions based on the client country, structured generation and integrated tax logic.
A level of transparency rarely offered: no hidden processing.

Test the demo

Every system presented here has been designed, tested and used in real conditions before being offered. No prototype, no fictional demo — tools that run and have been proven in practice.

The approach is the same for every project: defined scope, documented delivery, readable and maintainable code.
