Luminous builds internal tools, customer portals and integrations that replace spreadsheet workarounds. Get a free quote today!
Discuss Your Project
Build software for the process your current tools cannot hold. Luminous designs and develops internal tools, customer portals and the integrations between the systems your team already uses.
The usual starting point is a workaround: data copied between tools, a spreadsheet that has become the system of record, or an old application nobody wants to touch. We map that work first, then scope the smallest build that removes it.
For related delivery work, explore the That's Right Coaching platform and Pindrop, an internal research tool we built for our own work. Each case study describes its own scope. Yours depends on your users, data and systems.
Signs a workflow has outgrown its tools
| What happens today | What we can build |
|---|---|
| Staff retype the same details into two or three systems | An integration that moves agreed fields between systems when a record changes, with failed updates shown to a person. |
| A shared spreadsheet runs a core process | An internal tool with a proper database, user permissions, a change history and the views each role needs. |
| Customers email documents and ask for status updates | A customer portal for uploads, requests and status, connected to the records your team works from. |
| Reports take days to assemble by hand | A data pipeline and dashboard built on agreed definitions, so the numbers mean the same thing to everyone. |
| An old application blocks every change | A staged replacement, one module at a time, while the existing system keeps running. |
Build, configure or buy
Custom software is the right answer less often than it first appears. Before proposing a build, we check whether a product you already pay for can be configured to do the job, or whether an established tool covers most of it. We recommend building when the process is specific to how you work, when licence costs grow with every user, or when the data has to stay under your control.
How a build runs
- Map the process and the data. Who does what, which systems hold which records, and where errors appear today.
- Define the first release. Agree the users, screens, integrations and the checks that decide when it is done. Leave the rest for later releases.
- Design the data model and permissions. Decide what is stored, who can see and change it, and how changes are logged.
- Build in reviewable steps. Share working versions with the people who will use the tool, tested against real examples from their work.
- Move the data. Map, clean and test-import existing records before switching over, with a rollback plan.
- Launch and hand over. Hosting, monitoring, documentation and the support arrangement, agreed in writing.
Modernize without a risky rewrite
Replacing an old system in one move puts the whole operation at risk on launch day. We prefer to put a new service or interface in front of the part causing the most trouble, move users across, and retire the old code in stages. Each stage can be tested and reversed on its own.
Technology and ownership
We commonly build with TypeScript, Next.js, Go and PostgreSQL, and choose differently when your team, hosting or existing systems point elsewhere. The code repository, hosting accounts and domain should belong to your organization. Documentation covers how to run, deploy and change the system, so another developer could pick it up.
If the software also needs a phone or tablet client, see our mobile app development service. For a public website or booking experience, see web development. Where the tool should read documents or draft work with AI, see AI automation and workflow integration. For pipelines and follow-up inside an existing CRM, see CRM setup and automation.
Questions about custom software
What does custom software cost?
The number of user roles, screens, integrations and data sources, plus any migration work, set the cost. We price the first release after discovery, when those inputs are known, and scope later releases separately.
Can you work with our existing code?
Yes. We review it first, including dependencies, tests and hosting. Some codebases are worth extending; others cost less to replace in stages. The review explains which, and why.
How do you handle security and access?
We design permissions with the data model, keep credentials out of the code, log changes to important records and review access before launch. Regulated data brings its own requirements, which we agree with you before building.
What happens after launch?
Software needs dependency updates, monitoring and small changes as the process evolves. We agree maintenance cover and response times, or hand everything to your own team with documentation.
