Features

Manage invoices and documents efficiently

From e-invoices and incoming documents to traceable changes and teamwork: discover how AGYNAMIX® Invoicer supports your desktop invoicing workflow.

Native on Mac, Windows & Linux

Native desktop experience on Windows, macOS, and Linux. Work how you want, wherever you are, with a single, consistent interface.

E-Invoicing and Compliance Support

Depending on the use case, create ZUGFeRD invoices as PDF/A-3 files with embedded structured data or XRechnung invoices as structured XML files. Prepare your workflows for the e-invoicing requirements that apply in Germany.

Pro Incoming Document Workflow

Capture, review, approve, dispute, archive, and track supplier documents with PDFs, XML files, and attachments kept together in one structured workflow.

Ultimate AI-Assisted Document Analysis

Use local or remote AI endpoints to extract invoice data, match suppliers, and suggest expense categories while keeping every suggestion under your control.

Ultimate Client-Server for Teams

Run one host with multiple desktop clients so teams can work across several workplaces while the host database remains authoritative.

Designed for Speed

AGYNAMIX® Invoicer is a native desktop application without a browser runtime, designed for short startup times and responsive interaction.

Built for Privacy-First

In standalone mode, AGYNAMIX® Invoicer stores your business data locally; in client-server mode, it is stored on your self-hosted server. External services are used only when you deliberately configure or trigger them.

Traceable Archive: Local, S3, or SMB/UNC

Archive finalized documents locally with file-system protection, in Pro with S3-compatible Object Lock, or centrally on an SMB/CIFS network share via a UNC path. With SMB, protection against changes is configured through the file server and its permission or retention policies.

Built for GoBD-Friendly Bookkeeping

AGYNAMIX® Invoicer supports GoBD-style record keeping with local standalone storage or a self-hosted server, transparent changes, and exports under your control. Your tax advisor gets clean, well-structured data.
