Custom software development for the workflow your business already runs.
Custom software development is the design and engineering of a system around a workflow your business already runs: the records, the people who touch them, and the hand-off that currently lives in a spreadsheet or a chat thread. It is the right project when that work is frequent, specific, and costly when it fails.
Sunbeam is a software engineering company in Lucknow, Uttar Pradesh. We build these systems with teams across India and with clients in the Gulf, the United Kingdom and the United States. The first release should remove one bottleneck. When a product you can subscribe to already matches the way you work, we say so and help you start there.
The business case
What better looks like.
- One record of the work, with a status the team agrees on
- Fewer hand-offs that depend on memory or duplicate entry
- A codebase and handover your team can keep
What it is
Software shaped around one operational job
A marketing website helps a stranger understand the business and take a next step. Custom software helps a known group of people finish the same job again and again: raise a booking, move a case forward, see which orders are late, or show a customer the true state of their account. The projects can share a visual language. They need different scopes.
The useful test is whether the screen changes Monday morning. A dashboard nobody opens, or a portal that still needs a parallel spreadsheet, has not finished the job. We scope the release around the hand-off that hurts, and we write down what that release leaves for later. The record lives in one place, with a status the team agrees on, permissions that follow the organisation, and the awkward weekly cases included or explicitly deferred.
Who it is for
Teams that can point at the workflow
This fits owner-led companies, professional firms, operators and product teams. Some have no engineers and need a partner to own delivery. Some have an internal team and want help with one system. The shared requirement is a process that has outgrown inboxes and spreadsheets, plus a person who can make decisions while the work is underway.
It is a weak fit when the process changes every fortnight, when nobody owns the data, or when the goal is a simple brochure site. In those conversations we narrow the problem, suggest a smaller pilot, or recommend a product you can configure. A build goes ahead when the workflow, the users and the definition of a good week are clear enough to design against.
The work happens most days
Errors, delays or missed follow-ups already have a cost you can describe. A process that runs twice a year rarely justifies its own system.
A standard product would bend the business
You have tried, or seriously considered, an existing tool, and the workarounds would become the new process.
The first users are known
You can name the team, the customer group or the partner who will use the first release.
Someone can decide
A decision-maker can answer scope questions within a few days. Projects stall when every screen waits on a monthly committee.
How we work
The business problem comes before the stack
The early work is a map of the steps, the tools you already pay for, and the places information is copied by hand. We interview the people who do the work, not only the sponsor. The written recommendation includes what we suggest you leave unbuilt. During delivery you review a working slice. You own the source code, the data and the cloud accounts, unless a written agreement says otherwise.
Where does the time go?
Which step is slow, which step produces errors, and what a mistake costs in rework or in a customer waiting.
Who may see this record?
We separate viewing, editing and approving before we design screens. Retrofitting permissions is how simple tools become fragile.
What has to stay?
Accounting, identity, inboxes and industry platforms usually stay. We check for a reliable API before promising an integration.
What is true after launch?
We write the outcome in operational language: fewer status meetings, a customer who can see progress, a queue that is visible.
Typical stack
Next.js, Go, Postgres and AWS, unless the problem asks for less
For most custom business software we use Next.js, Go, Postgres and AWS. They are widely understood, which matters when another team has to own the system. We leave a piece out when the problem does not need it. A small internal tool may be Next.js and Postgres alone. A company already running on Azure should stay there if moving clouds would add risk without helping the workflow.
Interface
Next.js
Authenticated screens, forms and server-rendered pages. This is the part staff and customers touch, on a phone as well as a desk.
Services
Go
APIs, imports, scheduled jobs and integrations. A separate service earns its place when background work should not live inside the page render.
Records
Postgres
The system of record. Constraints and transactions suit bookings, cases, orders and permissions better than files that can disagree.
Operations
AWS
Hosting, file storage, queues and backups in an account you control, sized to the workload, with the release path documented.
Timeline ranges
Ranges you can plan around, with the assumptions visible
These ranges assume a stable scope after discovery, and access to the people who do the work. Cleaning years of spreadsheet history, waiting on a vendor with no API, or changing the workflow mid-build moves the date. We publish the range and the assumptions in the proposal. Discovery can stand alone, and it can end in a build, a configured product, or a smaller pilot.
1 to 3 weeks
Discovery
The workflow, the users, the data, the risks and a written scope for a first release. You should be able to decide, including a decision to stop.
6 to 10 weeks
One team, one process
An internal tool with a small set of roles. Typical when a single spreadsheet or inbox is the thing being replaced.
8 to 14 weeks
A portal or booking system
Permissions, notifications and one or two integrations. The extra time is usually the edge cases and the existing system.
3 to 6 months
Several teams
A broader platform, shipped in slices so the first workflow is live before the last one is designed.
Process
From the first conversation to a system you can run
The sequence stays the same from a focused tool to a larger platform. A booking tool for one team does not need the same discovery as a system that crosses departments.
01
Understand
You describe the work and what you have already tried. We listen for the constraint. A feature list is welcome, and it is not the starting point.
02
Diagnose
We map the steps, the data and the exceptions, then name the bottleneck in writing.
03
Design
We propose the smallest release, the stack, what sits outside that release, and a timeline range. You approve it before engineering starts.
04
Build
Engineering proceeds in slices. You review a working path on sample data you provide, while change is still cheap.
05
Launch
We test the real journey, deploy to an environment you can access, and document how it runs, how it is backed up, and who to call.
06
Improve
The first weeks of use show the next change. Maintenance or a second workflow is agreed as its own scope.
Who this is for
For teams ready to improve an important part of the business.
- Teams whose daily workflow has outgrown spreadsheets
- Companies a standard product would force into workarounds
- Sponsors who can decide during the build
Frequently asked questions
Useful questions before you begin.
Can you improve software we already have?
Yes. We can audit an existing application, stabilise what fails, and extend it when a rebuild would throw away working value. The recommendation comes after we have seen the code, the hosting and the workflow.
Who owns the code and the data?
You do, along with the cloud accounts, unless a written agreement says otherwise. Handover includes the repository, how a release is deployed, and where configuration lives.
What do you need from us to start?
A person who can walk through the workflow, examples of the real records, and access to any system we must integrate with. Discovery can begin before every credential is ready.
Do you work only with companies in Lucknow?
The studio is in Lucknow, Uttar Pradesh. We work with teams across India and with clients in the Gulf, the UK and the US. Calls are arranged around those time zones.
