What we do

Custom software

We design and deliver practical web, backend and business-system software around the way your organisation actually works.

ERP and business systems

Our highlighted area is Dolibarr ERP/CRM: implementation, custom modules, integrations, migration and ongoing improvement.

IT support and operations

We support systems after delivery, including upgrades, monitoring, troubleshooting and practical operational improvements.

DevOps and infrastructure

Docker, Linux, deployment, monitoring and high-availability architecture where the project genuinely requires it.

AI-assisted delivery

We use modern AI tools selectively for analysis, development, documentation, testing, automation and day-to-day operations, with human review.

Selected complex-systems experience

Our earlier projects include GIS, IoT, smart-city, public-sector and route-optimisation systems. New work in these areas is scoped with the appropriate independent partners.

Agile project management

From α to ω: preparation, planning and management.

Mobile applications

Mobile delivery is available with the right independent partner team when the project requires it.

Dolibarr ERP/CRM

Dolibarr is one of our highlighted areas: implementation, custom modules, integrations, data migration, training and operations.

What these projects involved

ERP and logistics

Raorg TransLog and other ERP projects involved complex shipment organisation, business workflows and operational data in one system.

Public-sector workflows

Projects for Békéscsaba Municipality, FKF, FODISZ and Budapest involved citizen services, route optimisation, spatial data and process management.

Health and monitoring

MedicalEvolution work combined monitoring, sensors, data flows and reliable web or backend components.

Fleet and infrastructure

Fleet management, toll-system and smart-city projects required integrations, mapping, operational data and infrastructure that can be maintained after delivery.

Online ordering

Restaurant and webshop projects such as kerekcsarda.hu, piccadillypizzeria.hu and szoszicafe.hu focused on practical online ordering and business workflows.

ERP implementation lessons

The OnSize Kft. project reinforced a practical lesson: an ERP system cannot replace client-side ownership, clean data, realistic scope and active user participation.

Full technical background and tools

Our wider partner network has hands-on experience across these technologies. We bring together the right independent team for the project instead of presenting every capability as an in-house service.

We start with process discovery, define ownership and scope, and document the decisions before implementation.

How we workClear scope

We use AI tools where they add practical value, while keeping human review and responsibility for the delivered result.

How we workPractical AI

Projects are delivered by T.A.Cs. with a stable network of independent professional partners selected for the work.

How we workRight-sized team

About T.A.Cs.

T.A.Cs. is led by Ferenc Deák, an independent software developer with experience in ERP, GIS, IoT, infrastructure and complex business systems.

Projects are delivered with a stable network of independent professional partners. This lets us bring together the right skills for a project without pretending to be a large in-house organisation.

We use modern AI tools where they provide practical value in analysis, development, documentation, testing, automation and operations. The delivered result remains subject to human review and responsibility.

How we work

  1. Discover: Understand the business process, constraints and desired outcome.
  2. Define: Agree scope, responsibilities, priorities and a realistic first delivery.
  3. Build: Configure, integrate or develop the smallest maintainable solution that fits.
  4. Verify: Test with realistic data and involve the people who will use the system.
  5. Operate: Document the result and support upgrades, monitoring and further improvement.

A successful implementation needs both technical delivery and active ownership on the client side.

Selected capabilities

  • ERP and integrations: Dolibarr, business workflows, APIs and data migration.
  • Complex systems: GIS, IoT, monitoring, logistics and high-availability infrastructure.
  • Practical AI: AI-assisted analysis, coding, documentation, testing and workflow automation.
  • Right-sized delivery: direct communication and an independent partner network.
