What we build

Custom Web Application Development: what we build

Browser-based software built around your exact workflows. Here are the six kinds of custom web application development work we are asked for most often.

From spreadsheet to software

What changes when a spreadsheet becomes a web application

Most custom web applications start life as a spreadsheet that the business has outgrown. These are the problems a web application removes.

Today, in the spreadsheet In the web application
One file emailed around, with several versions One source of truth, with access by role
Copying data between sheets by hand Automated workflows that move data for you
Approvals by email, hard to trace In-app approvals with a full audit trail
Formulas that break when someone edits them Validated business rules that cannot be overwritten
No record of who changed what Every change logged with user and time
Reports built by hand every week Live dashboards and scheduled exports

Straight answers

Is Custom Web Application Development right for you?

We would rather recommend less than sell you more. Here is how we judge it.

A good fit when

  • A key process runs on spreadsheets or email
  • Several roles need different access
  • You need an audit trail or approvals
  • Off-the-shelf tools force workarounds

  • A mature SaaS tool already fits

    If a product covers most of the process, configuring it is quicker than building.

  • Only one person uses it

    A well-structured spreadsheet or low-code tool may be enough.

  • The process is not yet settled

    Map and agree the process first, or start with a prototype.

FAQ

Custom Web Application Development FAQ

What is the difference between a website and a web application?

A website mainly presents information to visitors, while a web application lets users log in and get work done, such as submitting requests, managing records or approving tasks. Web applications need backend logic, a database and user management.

When should we build a custom web application?

Build one when a core process runs on spreadsheets or email, when several roles need controlled access, or when off-the-shelf tools force workarounds. If a mature product already fits most of the process, configuring it is usually the better choice.

Can a web application work on mobile phones?

Yes. We build responsive web applications that work on phones, tablets and desktops, and can add offline support or a companion mobile app where field use demands it.

Can you move our spreadsheet data into the new application?

Yes. We map spreadsheet columns to the new data model, clean and validate the data, migrate it, and check the results with your team before go-live.

How do you secure a custom web application?

We use role-based access, secure authentication with single sign-on where needed, encryption in transit and at rest, input validation and audit logging, and test against common web vulnerabilities before release.

Who maintains the application after launch?

We can provide ongoing support and improvements, or hand over documentation and code to your team. Most clients keep us involved for updates, monitoring and new features.
