Who this is for

Custom software development for startups and growing companies.

Almost every custom software development project we take on starts from one of these three situations. Recognise yours and the rest of this page gets more useful.

  • A startup with customers before a product

    You have a waiting list, a deck and a deadline. What you need is a first release small enough to ship and real enough to sell.

    Scope one journey, build it, put it in front of users.

  • A growing company running on spreadsheets

    It worked at ten people. At forty it costs hours a week, and one wrong cell costs a customer.

    Replace the process with software that enforces it.

  • A build that stalled

    A previous team left you with something half-finished, undocumented and slower every month.

    Audit, stabilise, then ship again.

Old tools on one side, the software that replaced them on the other

What you get

What our custom software development services include.

Anyone can list frameworks. These are the six artefacts that land in your hands, and roughly when.

  1. A written scope, before anything is built

    Goal, constraints, what we are building first and, just as important, what we are deliberately not building yet.

  2. A clickable prototype in week one

    Real screens you can put in front of users and investors before a line of production code exists.

  3. Working software every two weeks

    A demo you attend and a written report of what shipped, what slipped and what is next.

  4. Code in your repositories from day one

    Your GitHub, your cloud accounts, your IP under NDA, with commit access from the first sprint.

  5. Tests on the paths that matter

    Automated coverage on the flows where a failure costs you money, not a coverage percentage for its own sake.

  6. Documentation and a handover

    Release notes, architecture notes and a walkthrough so your team can carry the system without us.

What it costs

How much does custom software development cost?

Ranges, not single numbers, because custom software development cost is driven by integrations and migration scope rather than screen count. The two ways to pay for it, fixed-scope and monthly pricing, are set out in full. You get the exact number in writing after one call.

    Start with Platform

These ranges reflect work delivered in 2025–26. Custom software development rates move with integration count, data migration and compliance scope, so every engagement starts with a written scope listing exactly what is included and what is not.

How it runs

How a custom software development project runs, week by week.

The same process on every engagement, whichever package you start from; it is our delivery process applied to your build, not a variant invented for this page.

  1. Scoping call

    A working call about the outcome and the constraints. Not a pitch.

    Day 1–3

  2. Written scope and price

    Architecture options, timeline and a price range you can take to your board. If you want a number before that call, the cost calculator gives you one in a minute.

    Within 48 hours

  3. Prototype and build

    Clickable prototype, then working software in fortnightly sprints.

    Week 1 onward

  4. Launch and operate

    Deployment to your cloud, monitoring in place, then the next slice.

    Launch week

Proof

Custom software development projects we scoped, built and still support.

Different sectors, one process, and in each case the client owns the code.

How we work

A product engineering culture built on ownership and clarity.

The habits that decide whether software still works in year three. Here is the honest comparison: what most outsourced engagements look like, and what changes when you work with us.

How an engagement with QalbIT compares
The questionThe usual answerAt QalbIT
Who scopes itA salesperson, then a handover docThe founder and the engineer who will build it
Who writes the codeWhoever is on the bench that monthNamed senior engineers, in our office, no subcontractors
What you see weeklyA status deck and a percentageA working demo and the board it came from
When something breaksA ticket queue and an account managerThe engineer who wrote it, in your timezone overlap
If you want to leaveA migration project and a licence conversationThirty days notice · repos and IP were always yours

  • Principle 01

    Ownership over ticket-taking

    Engineers who ask why before they ask which framework. Scope questions come back before code goes out.

  • Principle 02

    Written over remembered

    Scope, estimates and architecture decisions are written down with the trade-off stated. Nobody relies on what was said on a call.

  • Principle 03

    Small over staffed

    Senior pods that hold the whole system in their heads beat large mixed teams that need a coordinator to function.

Engagement models

Flexible engagement models.

Choose how you want to work with us based on where your product is today. We help you validate, ship and then scale without forcing you into a one-size-fits-all model, and how we price projects follows the model you pick.

  • Best for defined scope

    Fixed-scope projects

    Best when requirements are clear and we can estimate precisely.

    • Clearly defined scope, milestones and deliverables.
    • Predictable budget with upfront estimates.
    • Ideal for MVPs and discrete feature releases.

    Works well with good documentation or a short discovery

  • Most chosen

    Dedicated product squad

    A cross-functional team that behaves like your in-house product team.

    • Stable team for long-term ownership and roadmaps.
    • Capacity planned monthly with clear velocity.
    • Founder involvement on architecture and key decisions.

    When software is core to your business

  • Best for ongoing work

    Time & material / Agile

    Ideal for ongoing iterations, R&D and integrations.

    • Pay for actual engineering and design time used.
    • Flexible backlog and scope, prioritised every sprint.
    • Perfect for experiments and proof-of-concepts.

    When agility matters more than fixed scope

FAQs · Custom Software Development

Custom software development questions, answered

Cost, timelines, ownership, technology choices and what happens after launch.

Ask us directly →
Custom software development cost is driven by integrations, data migration and compliance scope rather than screen count. Our Launch band starts from mid four figures USD for one core journey in production, and Scale from low five figures USD for a full product with the integrations around it. You get a firm range in writing within 48 hours of the scoping call.
A first release usually lands in 6–14 weeks: 6–8 weeks for one core journey, 10–14 weeks for a fuller product with two to four integrations. You see a clickable prototype in week one and working software every two weeks after that, so the timeline stays visible from the start instead of being confirmed at the end.
You do, from day one. Repositories, cloud accounts and intellectual property sit in your name under NDA, and your team has commit access from the first sprint. There is no licence to renew and nothing to negotiate if you decide to carry the system on in-house or hand it to another team later.
Buy when your process is ordinary and the product genuinely fits it. Build when the part that makes you money is the part no product will hold, or when per-seat fees climb faster than your revenue does. We will say plainly when a commercial tool is the better answer, because a build you resent is not a reference.
Yes, and it is a large share of what we do. The usual shape is one core journey scoped, prototyped and shipped to real users, with the rest of the roadmap deliberately left out of the first release. You hold the repositories and the cloud accounts throughout, which matters the first time an investor asks what the company owns.
React, Next.js, Node.js, NestJS and TypeScript on most new builds, Laravel where your team already works in PHP, PostgreSQL or MySQL for data, and AWS with Docker for hosting. We choose what you can hire for and maintain rather than what is interesting this year, and the written scope names the stack before anything is built.
Launch is a release, not an ending. Most clients keep a small standing team for support, iteration and infrastructure, with monitoring and uptime targets in place from the first deployment. That is optional, and it ends or scales down on 30 days notice. If you would rather run it yourselves, you get documentation and a walkthrough handover.
Send us the problem in two lines. We book a working scoping call rather than a pitch, and within 48 hours you have a written scope, a timeline and a price range, including what we would deliberately leave out of the first release. It is free and yours to keep whether or not you hire us.
