Short answer
An off-the-shelf system is faster and cheaper to start with if your processes are standard. A custom system pays off when your competitiveness rests on how you work, you need integrations with specific systems, or the ready-made product forces you to change your processes and pay for features you don’t need. Often a hybrid is best.
Comparison
| Off-the-shelf system | Custom system | |
|---|---|---|
| Upfront cost | Lower | Higher |
| Speed of rollout | Fast | First version usually within a few months |
| Fit with your processes | You adapt to the software | The software adapts to you |
| Integrations | The ones provided | Any you need |
| Licences | Per user, recurring | Usually none |
| Development | On the vendor’s roadmap | According to your needs |
When to choose off-the-shelf
- The process is standard (accounting, payroll, simple e-mail communication).
- You need a solution tomorrow.
- There are no specific integrations.
When to choose custom
- Your process is your advantage — for example, managing a dealer network or complex planning.
- You need integrations with industry or state systems.
- Licence costs grow with your headcount.
- You’ve tried off-the-shelf tools and they “almost fit”.
The hybrid
Often the best option is to use off-the-shelf accounting and build a custom system for what is unique to you, connecting the two. In our projects the first working version is typically ready in 6–9 months — see what is an MVP.
