Build · Custom Software Development
Custom software built around your business
We turn spreadsheets, email threads and disconnected tools into one system your team actually uses.
What kind of software does Netsta build?
Sales, stock, dispatch, service or HR — we bring the work your team repeats every day into one panel. Where off-the-shelf packages don’t fit, we build a system around the way you work.
You see a working version on a staging environment from the first weeks, so you watch the system take shape instead of waiting for a big reveal. After launch we maintain it and keep improving it as your needs change.

Off-the-shelf, customised package or custom software?
Short version: off-the-shelf SaaS for standard processes, a customised package for small differences, custom software when your edge is in your processes. We help with all three.
| Criteria | Off-the-shelf SaaS | Package + customisation | Custom software |
|---|---|---|---|
| Best for | Standard processes | Processes with small differences | Unique processes, integration-heavy work |
| Time to start | Days | Weeks | Weeks to months, phased releases |
| Fit with your processes | You adapt to the tool | Partial | The tool adapts to you |
| Integrations | Built-in connectors only | Through plugins | Any API or internal system |
| Data ownership | With the vendor | Shared | Fully yours |
| Long-term cost | Per-user subscription | Licence + customisation | Independent of user count |
Standard in every project

Performance

Clean, tested code

Frequently asked questions
How long does custom software take?
A focused first version usually goes live in 8–12 weeks; larger systems are released in phases. Your quote includes a dated plan.
Can you move our existing data into the new system?
Yes. Migrating data from spreadsheets or legacy systems is part of the plan, and we verify it with you before go-live.
Do we own the software?
Yes. The source code, database and documentation are handed over to you on delivery, with no licence lock-in.
Do you support it after launch?
Yes. A monthly maintenance plan covers monitoring, security updates and small improvements.
