Welcome to the first pre-release of Agynamix Invoicer.
Agynamix Invoicer is a modern desktop invoicing application built for businesses operating under German accounting regulations. This native app combines professional invoicing capabilities with strict GoBD compliance.
Core strengths
🔒 GoBD compliance by design
Agynamix Invoicer is built from the ground up to meet German GoBD requirements. Every published document becomes immutable and is protected by a cryptographic hash chain.
📄 Complete document lifecycle management
From quote to payment, the full sales process is covered: quote, invoice, corrections, and compliant state transitions with audit logs.
⏱️ Integrated time tracking
For service workflows, billable time can be tracked by project/customer and transferred into invoice line items.
🌐 Modern e-invoicing
Support for ZUGFeRD and XRechnung including PDF/A-3 invoices with embedded XML data.
🏢 Multi-tenant architecture
Run multiple business entities in one app, each with independent numbering, tax settings, and banking data.
🖥️ Native desktop experience
Runs locally on Linux, macOS, and Windows with no cloud dependency.

A tamper-evident audit trail with SHA-256 hashing and built-in verification workflows.
