A summary of what exists, what we have built over the past 40 years, and what we are now handing over to artificial intelligence (AI), step by step.
ERP — Our Core System
Developed in DataFlex and evolving since 1983. All source code and associated rights are held by us.
| Area | Description |
|---|---|
| Core framework | Menu system with user controls, permissions, utilities, program launcher, multi-company management, and archive |
| Master data | Customer and prospect management, customer contacts, web interface, territory allocation, sales representative commissions, as well as suppliers, products, and prices |
| Inventory management | Everything a merchandise management system needs: from point of sale to high-bay warehouse control, from quotations to invoices, from reorder proposals to incoming invoices, as well as stocktaking, storage locations, and repairs |
| Accounting | Everything an accounting system needs: several million journal entries, automatic postings using transaction codes, open items, advance VAT returns, foreign currencies, recapitulative statements, international workflows, year-end rollover, and more |
| Reports and lists | Custom reports, export to PDF, Excel, the web, and dashboards, as well as automated emails, XML invoices, and ZUGFeRD |
The system is used every day by several customers, including larger installations with 20 to 50 workstations. Some deployments use IBM Db2 Community Edition as the backend. The core framework is the same, while custom extensions are developed to meet each customer’s needs. External solutions such as warehouse management systems or portatour for field sales are also integrated.
In-House Tools and Utilities
Developed in C/C++ using Microsoft Visual Studio.
Numerous utilities have been created over the years, usually in response to a specific need. They can be grouped broadly as follows:
| Group | Examples |
|---|---|
| Documents and printing | Text-to-PDF conversion, form-driven output, and direct reading and writing of Excel files |
| Development tools | Text editors, utilities, and payment-terminal control |
| Web communication | REST API scripting tools, email, fax, and SMS communication, as well as a cURL interface |
Project Data
Since September 2026, all project information has been version-controlled in a public repository at github.com/dai-guru.
The complete source code and related information are also version-controlled; however, these repositories are not publicly accessible.
