Custom Software vs. Off-the-Shelf | FAMC Tech

The €50,000 question

"Should we build our own application or use something off the shelf?" It's perhaps the most common question we receive. And the correct answer is almost always: it depends.

We've seen companies spend significant amounts on custom software they didn't need — a generic CRM would have solved 90% of the problem. But we've also seen companies try for years to force their processes into generic applications, losing time, money, and patience.

When an off-the-shelf solution is enough

If your problem is standard — client management, invoicing, email marketing, project management — there are mature solutions tested by millions of users at reasonable monthly costs. Don't reinvent the wheel.

We had a client who wanted a "custom project management application." After a 2-hour analysis, we concluded that Trello with a few Zapier automations would solve everything they needed. Cost: under €50/month vs. the initial estimate of €15,000 for custom development.

When you need custom software

Your process is unique

If the way you operate is a competitive advantage, a generic solution will dilute it. We worked with a logistics company whose routing system was specific to their type of cargo. No off-the-shelf application covered the requirements. We built a solution that reduced their transport costs by 22%.

Integrations are critical

When you have 4-5 systems that need to communicate perfectly — ERP, CRM, e-commerce platform, WMS — and no standard integration works properly, custom middleware or an integrated platform is the only viable long-term solution.

Scalability matters

If you're growing rapidly and the generic solution limits you — either through cost (paying per user with 200 employees) or functionality — custom software becomes more economical long-term.

How we make the decision together

We never directly propose "let's build." Our process is:

Needs audit — What problem are we solving? Who uses it? What data is involved?
Existing solutions search — Does something already exist on the market? What does it cost? What compromises does it involve?
Cost-benefit analysis — Custom vs. off-the-shelf over 3 years. Including implementation, maintenance, training, and opportunity costs.
Rapid prototype — If we go custom, we first build a functional prototype in 2-4 weeks. Test with the real team. Adjust. Then build the final product.

Common mistakes

"I want exactly like X, but with a few changes." Often, those "few changes" represent 80% of development effort. If X already does 90% of what you need, use X and adapt your process for the remaining 10%.
Underestimating maintenance. Custom software doesn't end at launch. Bugs, security updates, new requirements — budget 15-20% of the initial cost annually for maintenance.
Vague specifications. "I want an app that does everything" is not a specification. The clearer the requirements from the start, the closer the result will be to what you need.

Conclusion

The decision between custom and off-the-shelf isn't a technical one — it's a business one. Sometimes the best advice we can give is "don't build, buy." Other times, the right solution doesn't exist on the market and needs to be created. What matters is making the decision based on data, not impulse.
