Built for

Your workflow lives in spreadsheets, inboxes, paper, or disconnected tools.
Office, field, customer, or vendor handoffs create rework and missed details.
Your current software almost fits, but requires constant workarounds.
You want to use AI, but need clarity on cost, risk, quality, and governance.

Services

Consulting first, with the ability to build and host the system.

The work starts by understanding the business workflow. When custom software is the right answer, Arnhem Advies can design, build, and host it.

Business Technology Consulting

Map the workflow, clarify the real problem, and decide whether the answer is a process change, a better tool, custom software, or AI.

- Workflow and requirements discovery
- Process cleanup and system selection
- Vendor, tool, and architecture decisions
- AI use-case evaluation

Custom Systems, Web Apps, Websites, and Hosting

Build practical software for the parts of the business where generic tools are too loose, too rigid, or too disconnected.

- Internal tools, dashboards, and portals
- Scheduling, reporting, and field/office workflows
- Service websites with contact or quote flows
- Cloudflare, Vercel, Supabase, DNS, and deployment setup

Responsible AI Adoption

Use AI where it creates real leverage, with operating practices for token cost, model choice, review gates, and verification.

- Token-cost planning
- Model tiering
- Change control and review gates
- Verifiable workflows with tests, types, and reproducible checks

Proof

TradesTrack proof: full systems, not slide decks

The flagship proof is a mobile, web, and backend field-operations system with offline-first workflows, Supabase/Postgres, auth, row-level security, generated database types, testing, UAT coverage, and change-control discipline.

Engineering range

The underlying work spans edge apps, internal tools, data-backed systems, automation services, websites, and hardware-adjacent operational utilities. The point is not the subject matter of each build; it is the ability to choose the right architecture, ship the workflow, and verify that it works.

Responsible AI Adoption

Use AI where it creates leverage, with practices that manage cost and risk.

Estimate token costs

Treat AI usage as a visible project cost line instead of a vague tooling expense.

Choose the right model tier

Route work by risk and complexity instead of overspending on every task or underpowering critical work.

Gate risky changes

Use review and verification where AI output can affect data, money, permissions, compliance, or customer trust.

Verify the workflow

Prefer stacks and processes where tests, types, reproducible environments, and acceptance checks can prove the work.
