What TreeSolid Systems builds for clients

Processes drawn true, then built to run.

TreeSolid Systems GmbH offers software development, custom digital applications, system integration, and IT consulting for businesses in Germany. Each service can stand alone or combine into a larger programme. This page compares the offerings so you can identify a sensible starting point. If you already know your process problem, the automation and consulting pages give more detail. For a first discussion, contact us at [email protected].

Where to start

Software shaped around your operation

Custom software development

Custom software is built when standard products cannot match your process, data rules, or reporting needs. We develop web applications, internal business tools, and service components that connect to your existing landscape. The build follows your process model, so screens and logic reflect real tasks. Releases are planned in stages, which lets users react before everything is finished. The result is software shaped around your operation rather than your operation reshaped around a product.

Digital applications for daily work

Digital applications serve specific jobs: registering a customer, tracking a delivery, approving an invoice, or preparing a report. We design the screens around those jobs and the people who perform them. Search, validation, and error messages receive the same attention as the main workflow. A tool that is fast and clear gets used. A tool that requires a workaround gets abandoned, and the old spreadsheet returns.

Process modelling and BPMN

Process modelling turns daily work into a diagram that everyone can check. We model tasks, roles, decisions, and system connections in BPMN notation. The model serves as the basis for automation design, testing, and training. It also helps new staff understand how work moves through the company. Modelling is available as a standalone workshop or as the first phase of a build project.

Automation

Business process automation

Hands modelling on the oak bench

Automation services cover workflow automation, RPA, and process orchestration across systems. We identify steps that repeat with stable rules and move those steps into software. Approvals, document checks, data transfers, and notifications are frequent candidates. Human judgement stays where judgement is needed.

The automation page explains the method, the tool choices, and the pitfalls we see most often in German businesses.

Connecting what you already run

Integration

System integration

Integration connects ERP, CRM, accounting, and specialist systems so data flows without manual copying. We build API connections, file exchanges, and database links where those fit. Each interface needs rules for validation, duplicates, and failures, defined with the departments that own the data.

Older systems

Legacy system modernisation

Legacy modernisation covers assessment, wrapping, staged replacement, and data migration. We first record what the legacy system does, including undocumented reports and edge cases. Then we decide what stays behind an interface and what moves to new code, keeping the business running during the change.

Decisions

IT consulting and needs analysis

Consulting starts with a status-quo assessment: systems, data, interfaces, and the process as it actually runs. We compare configuration, low-code, custom build, or process change, each with effort, risk, and maintenance implications. That suits companies facing a vendor decision, or teams whose last project produced software nobody uses.

Low-code delivery, and when custom is better

Low-code delivery uses platforms such as Microsoft Power Platform to build internal apps and workflows quickly. Power Apps handles forms and data entry. Power Automate handles flows between Microsoft 365, Dynamics, and other connected services. Power BI presents the results in reports. We advise on when low-code is enough and when custom software gives better control. That judgement saves money in both directions.

A practical distinction

Low-code is faster for contained internal tools. Custom software gives more control for complex, long-lived, or high-volume logic. The choice depends on how the process will change, how many systems it touches, and who will maintain it after launch.

We make that call with you before a platform is chosen, so the build does not outgrow its foundation in the first year.

Careful use

AI-assisted workflows, used carefully

AI can help with document reading, text classification, and drafting, but only inside a defined process. We examine where a model adds value and where a simple rule works better. Data protection, accuracy checks, and human review are part of the design. AI agents in enterprise processes need clear limits on what they may change. Our consulting work sets those limits before any tool is connected.

Testing, training, and launch support

Delivery includes testing with real data, user training, and support during the first weeks of use. Test cases come from the process model, including error paths and missing data. Training covers daily tasks and the actions to take when something goes wrong. Launch support handles the questions that only appear in live operation. A release is finished when your team can run it, not when code is merged.

Maintenance and further development

Software needs care after launch: bug fixes, small changes, and adaptations when other systems change. We can agree maintenance arrangements that match your release rhythm. Small improvements are easier on a system that was documented well at delivery. A quarterly review of process volumes and user feedback often reveals the next sensible step. Maintenance is planned work, not a surprise.

Finding your entry point

Choosing the right service

If you know the process and the systems, automation or integration may be the right entry. If the process is unclear, start with modelling or consulting. If a standard tool almost fits, a custom application may close the gap. Use the contact page to describe your situation in a few lines. We will suggest the service that matches the problem, and say plainly if none of our services fit.

Questions from clients

Can one project combine several services?

Yes. Consulting, modelling, build, integration, and training often form one engagement, sequenced by the needs of the process.

Do you replace our ERP or CRM?

Normally no. We connect to existing systems and build the missing pieces around them.

What is the difference between low-code and custom software?

Low-code is faster for contained internal tools. Custom software gives more control for complex, long-lived, or high-volume logic.
