Custom software development

Custom software development

Off-the-shelf tools rarely fit the way your company actually works. ATA Technology builds custom software around your processes: business applications, customer portals, integrations and internal tools that save time and remove manual work.

01What we build

  • 01

    Business applications

    Planning, operations, quoting and administration systems tailored to your workflow.

  • 02

    Customer and partner portals

    Secure self-service environments with accounts, roles and document sharing.

  • 03

    Integrations & APIs

    Connecting your ERP, CRM, accounting software and external services so data flows automatically.

  • 04

    Process automation

    Replacing spreadsheets, e-mail chains and copy-paste work with reliable software.

  • 05

    Legacy modernisation

    Rebuilding outdated systems step by step without disrupting daily operations.

02Built to last

We choose proven, widely used technology so your software stays maintainable and other developers can work on it too. Every project includes automated tests, documentation and a deployment pipeline, and you own the source code.

03What you get

  • Process and data analysis

    A clear map of your current workflow, data and bottlenecks before anything is built.

  • Clickable prototype

    Screens and flows your team can test with real scenarios from daily work.

  • Web application with roles

    A secure application with accounts, roles and permissions that match your organisation.

  • Integrations with your systems

    Connections to your ERP, CRM, accounting or other tools, so data is entered only once.

  • Data migration

    Existing data from spreadsheets or legacy systems cleaned up and moved into the new application.

  • Documentation and handover

    Technical documentation, user guides and a deployment pipeline that your team or ours can maintain.

04Who it's for

  • 01

    Planning in shared spreadsheets

    An operations team plans people, jobs or materials in spreadsheets and keeps losing track of versions and changes.

  • 02

    Too many disconnected tools

    Data is copied by hand between the webshop, accounting software and CRM, which causes errors and double work.

  • 03

    Customers asking for status updates

    Clients e-mail and call for updates on orders, files or projects that a self-service portal could show them directly.

  • 04

    A legacy system nobody dares to touch

    A business-critical application runs on outdated technology and has to be replaced without stopping daily work.

05How we work

  1. Walk through the work

    We sit with the people who do the work and map every step, exception and handover in the current process.

  2. Model the data

    We define the core entities, statuses and rules first, because they decide how flexible the software will be later on.

  3. Prototype the key flows

    The most frequent and most error-prone tasks are prototyped first and tested with the people who will use them.

  4. Build and migrate in phases

    We deliver module by module and migrate data per phase, so old and new can run side by side when needed.

  5. Train and hand over

    Users get clear guidance, administrators get control, and we stay available for support and further development.

09Frequently asked questions

When is custom software better than an off-the-shelf package?

When your process is a competitive advantage, when you combine several tools with manual work in between, or when licence costs grow with every user. Custom software fits your workflow exactly and grows with you.

Can you integrate with our existing systems?

Yes. We connect to ERP, CRM, accounting and e-commerce systems through their APIs, or build a custom integration layer when no API exists.

How do you estimate a custom software project?

We start with a short discovery phase to define scope and priorities. Based on that we give a clear estimate and plan, often starting with a first version that delivers value quickly.

Can the old and new system run in parallel?

Yes. When the risk calls for it, we migrate in phases and keep both systems in sync until the new one has fully taken over.

Can the software grow with our company?

Yes. We design the data model and architecture so new modules, users and integrations can be added later without starting over.

Will our employees need training?

We design the screens around tasks your team already knows, so they feel familiar, and we provide guides or sessions for users and administrators.
