Custom Software & Internal Platforms
Custom software development is building production-grade software around your process instead of the other way round — client management systems, workforce platforms, admin dashboards, internal tools. Lets Automation, Surat, India, builds on FastAPI and Next.js with proper deployment and monitoring. Fixed scope, fixed price, and you own the code, the server and the data.
Sound familiar?
- You've outgrown spreadsheets, but no off-the-shelf product fits how you actually work.
- You're paying for software you use a fifth of.
- The business runs out of Excel and WhatsApp groups, and only one person understands the sheet.
- A no-code prototype worked for ten users and broke at a hundred.
- Each site or branch keeps its own records, and nobody sees the whole picture.
What we build
Client and project management systems
- What it is:
- Leads, proposals, contracts, projects, invoicing and support in one system — including GST e-invoicing workflows.
- What it replaces:
- Client data scattered across disconnected tools.
- What changes:
- Every team sees the same pipeline, stage and history.
Workforce and attendance platforms
- What it is:
- Biometric attendance, shift and leave rules, salary calculation and approvals, multi-tenant across locations.
- What it replaces:
- Attendance and payroll tracked by hand across sites.
- What changes:
- Payroll runs from the data instead of a reconciliation marathon.
Admin dashboards and internal tools
- What it is:
- One place to configure, manage and monitor products, orders or operations, built for the people who use it daily.
- What it replaces:
- Five screens and a spreadsheet.
- What changes:
- Day-to-day updates take minutes, and management can see status.
Production engineering
- What it is:
- FastAPI backend, Next.js frontend, containerised deployment, CI pipeline, monitoring and backups.
- What it replaces:
- A prototype that nobody can maintain.
- What changes:
- Software you can run — and hand to another team — for years.

Common questions
Why custom software instead of an off-the-shelf product?
Buy when a product fits most of how you work. Build when the process is your edge, or when no product fits and you're either paying for features you don't use or running the business out of spreadsheets. We'll say which in the written plan — sometimes the honest answer is a better spreadsheet.
How much does custom software cost?
We don't publish fixed prices for custom software, because the price depends on scope — how many channels, systems and features you want included changes what we build. What we do fix is the quote: after a free 30-minute call you get a written plan with a fixed scope, fixed price and fixed timeline before any code is written. No hourly billing, and if you add to the scope later, that's quoted separately and in writing.
How long does custom software take to build?
We build in 4–8 week sprints with a working demo every two weeks. Most clients see their first automation live within about 6 weeks. The written plan you receive after the free call includes a fixed timeline for your specific scope.
Do I own the code and data?
Yes. You own the code, the server and the data. We build on tools like n8n and open APIs so there's no licence that scales with your usage, and there's no 12-month lock-in — you can take the system in-house whenever you want, or keep us on for support.
Do you work with businesses outside Surat?
Yes. We're based in Surat, Gujarat, and work with businesses across India and remotely with clients abroad. Scoping, the fortnightly demos and support all run over calls and WhatsApp, so location doesn't change how we work.
