Complete PHP e-invoicing system: quotes, e-signature, Factur-X invoices and exports

PHP e-invoicing system built from scratch and deployed on your own hosting. Available as a complete solution or standalone modules, it includes quotes with online signature, compliant invoicing, one-click paid invoice generation, expense management, deposit tracking, and structured ZIP and CSV exports. No framework, no SaaS, no subscription.

Available as either a complete solution or standalone modules, this system covers the entire billing lifecycle, from quote creation and online signature to invoicing, payment confirmation, deposit tracking, expense management, and exports.

Deployed on your server, for a simple, stable and controlled workflow, and directly compliant with the electronic invoicing reform.

Once deployed, the system runs autonomously.

Automatic compliance (France, EU, international)

All invoices are generated directly in Factur-X format (EN16931), with no option or additional configuration required.

The system automatically distinguishes between types of operations, including the sale of goods and the provision of services, as well as the nature of the client (individual or business), in order to apply the appropriate tax rules and legal notices.

The system automatically covers the following cases:

  • France: standard VAT or micro regime (article 293B)
  • European Union: reverse charge if a valid VAT number is provided
  • International (outside EU): invoicing without VAT with export mentions
  • Operation types: sale of goods and provision of services with appropriate tax handling
  • Client type: individual or business with applicable tax rules

These rules are built into the system to prevent errors, missing information and inconsistencies between amounts, VAT and legal mentions.

Exports reflect the applied tax treatment for each transaction, ensuring direct consistency with invoicing rules.

Issuer configured for French regulations

The system is configured for a France-based issuer, ensuring consistency in tax rules and legal mentions.

More complex cases (non-French issuer) require specific adaptations and are handled as custom implementations.

Who this system is for

This system is for freelancers, independents and SMEs who want to manage their invoicing without depending on an external platform, without paying a monthly subscription and without sharing their data with third parties.

The system runs directly on your server, without relying on external platforms.

You keep full control over your data, your structure and how the system evolves.

Deployed on your hosting

The system is installed directly on your server, your data stays with you, with no intermediary platform, no subscription.

Delivered with documentation

Every component comes with clear documentation, designed for autonomous onboarding and straightforward evolution over time.

Available modules

Regulatory updates

The system includes ongoing regulatory compliance assistance, limited to updates related to electronic invoicing regulations (Factur-X, XML standards, tax obligations, and exchange formats).

These adjustments apply to the invoicing module, ensuring long-term compliance of the system with legal requirements, without adding new functionalities or extending the original scope.

Demo

Six-video demonstration covering the complete system: platform overview, quote creation with online signature, invoice generation, payment confirmation, payment and invoice exports, deposit tracking, and expense management.

Setup

Before deployment, a configuration questionnaire is used to prepare your environment: company details, invoicing settings, emails, visual identity, banking information, insurance details, and operating parameters.

Access the configuration form

This step reduces installation time and allows the system to be delivered preconfigured for your business.

The system is then installed and configured directly on your hosting environment.

Once deployed, you have access to a complete electronic invoicing environment, with no subscription fees and no dependency on external services.
