The question every company should ask itself before purchasing software
Generic software has a clear value proposition: it is ready to use, has proven support, and is cheaper in the short term. Custom software has another proposal: it adapts exactly to how your company works, and can be a competitive advantage that no competitor can replicate by purchasing the same tool.
The decision is not simple and does not have a single answer. It depends on the type of process, the size of your company, your speed of change and how much current inefficiencies represent in specific costs.
When generic software is the correct answer
There are scenarios where hiring a third-party tool is clearly the smart move. If the process you want to cover is standard in your industry (accounting, electronic invoicing, basic project management), mature generic software solves it without having to reinvent the wheel.
Generic software also makes sense when the company does not yet have clear processes. Building custom software on immature processes is very expensive because you will have to change it constantly.
- Industry standard processes without differentiation.
- Company in early phase with processes still being defined.
- Investment budget less than S/ 15,000.
- There is no integration with other proprietary systems.
- The internal technical team does not have the capacity to manage custom software.
When custom software is the right decision
If your company has processes that are part of your competitive differentiation—how you quote, how you manage clients, how you control your operation—and those processes do not fit into any generic software without major adaptations, you have a clear case for custom software.
Also when you have existing systems (ERP, CRM, your own payment platforms) that need to be integrated, and no generic software connects correctly with all of them.
- Own operating processes that are a source of competitive advantage.
- Multiple existing systems that need to be integrated.
- Medium or large company with complex and variable operations.
- The cost of current inefficiencies exceeds S/ 5,000 per month.
- You need completely customized reports and dashboards.

The comparison table that no one wants you to see
Generic software vendors typically present only the initial cost. Those with custom software usually present only the potential for savings. Here the complete comparison.
| Criterion | Generic software (Odoo/SAP) | Custom software |
|---|---|---|
| Initial cost | S/ 0 – 5,000 (licenses) | S/ 15,000 – 100,000+ |
| Monthly cost | S/ 500 – 5,000 (subscription) | S/ 300 – 2,000 (maintenance) |
| Time until first version | 1–4 weeks | 2–6 months |
| Adaptation to your processes | Partial (you adapt to the software) | Total (the software adapts to you) |
| Customization cost | S/ 5,000 – 30,000 extra | Included in development |
| Dependency risk | High (vendor lock-in) | Low (own code) |
| Scalability | Limited by provider | Total (you define the roadmap) |
The hybrid scenario that works for many Peruvian companies
Most companies do not need to choose between one or the other absolutely. The smartest combination for many medium-sized companies is: use mature tools for standard functions (accounting, electronic invoicing with SUNAT, human resources) and custom build only the modules that are specific to the business.
This approach reduces costs without sacrificing differentiation where it matters.
