What started in 1996 as the foundation for an electronic tax return is today a standard application used by millions – and still evolving. For many years, mgm technology partners has supported the Bavarian State Office for Taxes in developing and maintaining key ELSTER components, including the "Mein ELSTER" portal. With A12, tax administration experts can model and update validation rules across more than 1,000 tax models themselves – without developer involvement.
The result: faster response to regulatory changes, lower maintenance effort, and a platform that stays reliable at massive scale.
A12 is going open source in May 2026 – in close coordination with the Bavarian State Tax Office.

“In the implementation of ELSTER we opted for a lean project approach with controllable implementation steps. In small teams our experts of fiscal and taxation matters cooperate directly with the technical experts."

Chefs Culinar Enterprice
Pricing at scale. Sales keeps moving.
10 million individual prices, complex contract structures – and a migration running in parallel with daily business.
Chefs Culinar built its market position on customer-specific pricing. To manage that complexity without slowing down sales, mgm technology partners developed Enterprice – a dedicated price management platform built on the A12 enterprise low-code framework. The application handles around 10 million individual prices through a guided workflow, offloads complex pricing logic from the core ERP, and serves as the central data hub between the legacy system and the new SAP S/4 HANA environment throughout the ongoing migration. The SAP-integrated successor application, EnterpriceSAP, is in its final development phase and is set to go live later this year.
The bottom line:
Highly complex pricing processes become fully manageable – without compromising customer-specific conditions, without disrupting day-to-day operations, and with complete readiness for the future SAP landscape.
