Business application

Custom Business Software — SME internal application

I design and develop business software tailored to your internal processes, to replace scattered tools and spreadsheets.

Your current tools can no longer keep up with your business growth

Your team uses multiple disconnected tools, complex Excel spreadsheets or manual processes that take time and generate errors. You need an internal application that centralizes your data and automates your workflows. Custom business software is designed exactly for your processes, not for generic use cases that only half match your needs.

Who this service is for

Suitable if

  • You use Excel or Google Sheets for critical and complex processes
  • Your teams juggle between 3 to 5 disconnected tools for the same workflow
  • You have specific needs that market SaaS solutions don't cover
  • You want to centralize your data for decision-making

Not suitable if

  • An existing SaaS solution already covers 80% of your needs
  • Your need can be solved by simple automation without a dedicated interface

Expected results

  • An internal application designed for your exact processes
  • Centralization of your data in a single reference
  • Automation of repetitive tasks and error reduction
  • Interface accessible to the entire team, without complex training

Deliverables

  • Business process analysis and workflow modeling
  • Responsive web interface adapted to your teams
  • Data management, import/export and reporting
  • Access rights and user role management
  • Deployment and user documentation
  • Post-delivery support

Scope examples

Excel spreadsheet replacement

Project management, order tracking or scheduling application that replaces an unmanageable Excel file.

Internal workflow tool

Validation pipeline, progress tracking or request processing between multiple services.

Pilot dashboard

Consolidated dashboard with real-time data, charts and alerts for management.

Work method

I start with a framing workshop to understand your processes, pain points and priorities. Then I design the application and develop it through iterations, with regular demos to validate alignment with your needs.

Pricing

Starting at €5,000

Fixed price after framing

The rate depends on process complexity, number of roles and necessary integrations.

Frequently asked questions

How long does development take?

Between 4 and 10 weeks depending on process complexity and number of modules. Prior framing provides a precise timeline.

Can I migrate my existing data?

Yes. I generally plan a migration phase to import your data from Excel, CSV or other sources.

Will my team be able to use the application without training?

The interface is designed to be intuitive. User documentation and a presentation session are included.
