Custom software or off-the-shelf: when your own software pays off
Spreadsheets, ready-made industry software or your own system? How to tell when off-the-shelf software holds you back, and how custom software is built step by step.
Most companies start with spreadsheets, email and a ready-made tool. That's the right call. At some point, though, the team works around the programs more than with them. Then the question is: keep adapting, or build your own software?
When off-the-shelf is the right choice
- Your process is standard for your industry and the software covers it well.
- You need accounting, payroll or email: mature products exist, nobody should reinvent them.
- Monthly licence costs are reasonable and the software grows with you.
Warning signs: this is where off-the-shelf holds you back
- Data is copied between programs by hand, every day.
- Important information lives in spreadsheets only one person understands.
- The team says things like “the system can't do that”.
- You pay licences for many features and use few.
- Customers ask for a portal, an app or a status you can't provide.
What custom software typically covers
- Customers, orders and quotes in one place (CRM).
- Inventory, stock levels, reordering and goods receipt.
- Customer or partner portals with their own login.
- Roles and permissions, plus a log of who changed what and when.
- Reports, exports and integrations with accounting, shop or till.
How custom software is built without a mega-project
- 01
Map the processes
I look at how orders, stock and customers really run today.
- 02
Start with the biggest pain
First the part that saves the most time, often usable within weeks.
- 03
Migrate the data
Existing spreadsheets and legacy data are checked and imported.
- 04
Extend step by step
Further modules follow once the system has settled into daily work.
What to look for when you commission it
- The source code and the data belong to you, not the developer.
- There's a fixed price per stage, not just hourly rates.
- You regularly see the real state of the work, not just presentations.
- The software runs on servers you control, in the EU if you prefer.
The “Orders & inventory” live demo shows what such a system feels like: create an order, send it through production, reorder stock and see every change in the audit log.
