Custom software or a standard ERP: which fits your business?
If your processes follow the norm of your sector, a standard ERP is almost always faster and cheaper. If your core process deviates on purpose, custom software earns its money back.
A standard ERP wins when your process is standard.
An off-the-shelf package is built for the processes nearly every company runs the same way: accounting, invoicing, ordinary order processing. Those processes come ready-made.
You pay a predictable licence price, you pick from a large ecosystem of vendors and consultants, and you are up and running quickly. For a business that works the way its sector works, this is the rational choice.
- Your processes follow the norm of your sector, with no deliberate deviation
- You want a fixed, predictable licence price
- You want a large vendor with a broad ecosystem around it
Custom software wins when your deviation is your edge.
Many SMEs make their money precisely with a process nobody else has: their own order flow, an unusual planning method, a warehouse that runs differently. A standard package presses that process into the shape the vendor designed.
That is when the shadow administration appears: Excel alongside the system, lists on the shop floor, steps that happen outside the software. The system fits, except in the place where the money is made.
What custom software at RUAL means in practice.
We build your software on Core, our own no-code platform. A first working version is usually there in 6 to 12 weeks, not after a year.
- A fixed price and schedule after the blueprint in weeks 2 to 3
- The build invoiced by the hour, with project work, SLA work and out-of-hours work itemised separately
- A licence from €515 per month, with hosting, DevOps, security and backups included
- Cancellable monthly, and under our terms the application is yours
The honest comparison at a glance.
Both sides win somewhere. The table sets them side by side; the project cost of custom software depends on scope, which is why you only get it as a fixed figure after the blueprint.
Custom software and standard ERP side by side
| Aspect | Standard ERP | Custom on Core |
|---|---|---|
| Standard processes | Strong: the package is built for them | Possible, but you pay for what the package already has |
| A deviating core process | Adapt to the package, or add Excel beside it | The software follows your process |
| First working version | Fast with a standard setup | Usually 6–12 weeks |
| Price certainty up front | Fixed licence price | Fixed price and schedule after the blueprint (weeks 2–3) |
| Running costs | Predictable licence price | Licence from €515 per month, build billed by the hour |
| Ownership | The package stays the vendor's | The application is yours |
The questions we get most about this choice
Three questions we hear in nearly every advisory call.
Is a standard ERP always cheaper than custom software?
To buy, almost always. The question is what it costs you when your core process does not fit the package: shadow administration in Excel, extra handling per order, staff working around the system. Custom costs more to start and less when the deviation is your edge. With us the licence starts at €515 per month and the build is billed by the hour, with a fixed price after the blueprint.
How quickly is custom software there, compared to a package?
A standard package is faster when your process is standard. Our first working version is usually there in 6 to 12 weeks, and from week 4 you watch working software in your own environment every week.
Are we tied to you after delivery?
No. Under our terms the application is yours, you cancel the licence monthly, and your own people can keep building on Core themselves. We maintain the platform and update it daily.
