Application development

Custom software development

Bespoke web and mobile applications built around how your business actually works, delivered in production-ready increments.

  • Fixed-scope project or dedicated team
  • From USD 45,000
  • Updated

The short answer

Custom software development means building an application specifically for your business rather than adapting an off-the-shelf product. LDelight designs, builds and runs these systems end to end, shipping working software every two weeks so value arrives before the project finishes.

Key takeaways

  • Working software in production within 6–8 weeks, not at the end of the project
  • Senior engineers only — no junior-heavy delivery pyramid
  • You own the code, the infrastructure and the documentation from day one
  • Fixed-scope or dedicated-team commercial models
Custom software development

Off-the-shelf software is the right answer more often than most agencies will admit. It stops being the right answer when the process it forces on you is the thing that differentiates your business — at which point you are paying a licence fee to be worse at what you are good at.

When custom development is the right call

We recommend building only when at least one of these is true: the workflow is a genuine competitive advantage, the integration surface between existing systems is where the cost actually sits, or licence and per-seat costs have outgrown the cost of ownership. If none of them apply, we will tell you so — usually in the first call.

How we build

Delivery runs in two-week increments against a prioritised backlog you control. Every increment ends with something deployed to a real environment behind a feature flag, so you are judging working software rather than a status report. Automated tests, infrastructure-as-code and CI/CD are part of the first increment, not a later phase — retrofitting them is what makes projects expensive.

What you are left with

At handover you hold the repository, the cloud accounts, the pipeline, the architecture decision records and a runbook. Nothing is hosted on an account we control unless you ask us to run it for you. That is deliberate: an engineering partner you cannot leave is not a partner.

How we deliver

  1. 1

    Discovery and architecture

    A structured workshop with the people who do the work. We leave with a domain model, a prioritised backlog and a costed architecture — delivered as a document you can take to any vendor.

  2. 2

    Design and prototype

    Clickable prototype of the critical paths, tested with real users before a line of production code is written.

  3. 3

    Incremental build

    Two-week increments, each ending in a deployable release behind feature flags. You see progress in an environment, not a slide.

  4. 4

    Hardening and security review

    Load testing, threat modelling and an internal penetration test before the first real user touches it.

  5. 5

    Launch and handover

    Phased rollout, monitoring and alerting configured, runbooks written, and your team walked through the system until they are comfortable owning it.

What you get out of it

  • A system that matches your process instead of constraining it
  • Predictable release cadence your business can plan around
  • No licence ceiling as headcount grows
  • Full ownership of code, data and infrastructure

FAQs about Custom software development

A first production release typically lands 6–8 weeks after kick-off. Full delivery of a departmental system is usually 4–9 months. We deliberately get something real into production early so the remaining scope is decided against evidence rather than assumption.

Yes, unconditionally. The repository sits in your organisation from the first commit, the cloud accounts are yours, and there is no licence or escrow arrangement. If you decide to move to another partner, nothing technical stops you.

Fixed-scope projects start around USD 45,000 for a focused system. A dedicated team is charged monthly against an agreed squad shape. We give a costed range at the end of discovery, before you commit to the build.

Frequently. We start with a two-week technical audit covering architecture, test coverage, dependency risk and security posture, then give you an honest assessment — including when the right answer is a rewrite and when it is not.
