When is a spreadsheet or standard tool no longer enough?
When limitations create workarounds, duplicated records, unsafe permissions or a missing critical step. I still check whether the current process can be fixed more cheaply first.

A focused custom web application
When spreadsheets or off-the-shelf tools are no longer enough, I build a focused web application around one specific business workflow.
What you will get
A usable application focused on one clearly defined problem, without unnecessary screens or features.
- workflow design
- clear user interface
- connection to the required data
- testing and team hand-over
How the engagement works
- 01
We define the roles, screens and key actions.
- 02
I prepare a simple working concept.
- 03
I build the application in small, reviewable increments.
- 04
After testing, we deploy it and hand it over.
How I decide what to build
I recommend an application when standard software cannot support the decisive part of a workflow or when a critical operation depends on a fragile spreadsheet. The first version covers one role, one data flow and only the screens that are genuinely needed.
Before development I define users, permissions, data, integrations and operations. We review the solution in small increments. Documentation covers deployment, access management, backups and the process for later change.
When to choose what
The categories can be combined, but each should solve a different part of the problem.
| Option | Use it when | Main output |
|---|---|---|
| AI audit | You need to choose a priority | Opportunity map and first step |
| AI agent | The task needs context and tool use | A controlled role with human oversight |
| Automation | The steps follow clear rules | A connected and monitored flow |
| Application | Standard software does not fit | A focused interface and data model |
| Consulting | You face one concrete decision | Independent recommendation |
| AI search visibility | The site needs stronger eligibility and content | Technical and editorial plan |
Price and timing
| Starting price | Included | Timing | What I need from you |
|---|---|---|---|
| A focused custom application starts at approximately €15,000 excluding VAT. The price covers design, development, data connections and testing within the agreed scope. | workflow design, clear user interface, connection to the required data, testing and team hand-over | Timing depends on the number of screens, roles, data sources and integrations. I confirm the initial scope before work begins. | A documented workflow, user roles, sample data and a person responsible for accepting the solution. |
Questions about custom application
Who owns the code and data?
Ownership, access, hosting and hand-over are agreed before work begins. Client data remains isolated from other projects.
Can the application connect to existing systems?
Yes, where a reliable API, webhook or secure export exists. I verify integration limits before confirming scope.
What happens after launch?
We test with real cases, fix issues within the agreed scope, document the system and hand it over. Support and further development can be agreed separately.

A documented workflow, user roles, sample data and a person responsible for accepting the solution.
The application addresses the agreed workflow. New modules and changes to the brief are planned as additional work.
