Why it is difficult to give a custom software price
If you ask ten development companies in Peru how much a custom web platform costs, you will receive answers ranging from S/ 5,000 to S/ 200,000. That is not misinformation: it reflects that the cost of software depends on variables that can only be estimated after understanding the project.
But there are reference ranges by type of project that allow you to gauge whether a proposal is reasonable or completely out of place. That's what you will find in this article.
Price ranges by project type in Peru (2026)
The following ranks assume development teams in Peru with proven experience, not freelancers without support or offshore companies with limited communication. They include requirements gathering, design, development, testing and initial deployment.
| Project type | Rank (S/) | Average time | What's included |
|---|---|---|---|
| Landing page + quote | S/ 3,000 – 8,000 | 2–4 weeks | Design, form, basic integration |
| Web platform with users and dashboard | S/ 15,000 – 50,000 | 2–4 months | Authentication, custom modules, reports |
| Mobile app (iOS + Android) | S/ 25,000 – 80,000 | 3–6 months | Native UI, proprietary API, push notifications |
| Customized ERP (own modules) | S/ 40,000 – 150,000 | 4–9 months | Integrated inventory, purchasing, sales, finance |
| Chatbot / AI Agent | S/ 8,000 – 40,000 | 4–10 weeks | Flows, generative AI, CRM/WhatsApp integrations |
| Integration between systems | S/ 5,000 – 25,000 | 3–8 weeks | APIs, data synchronization, automation |
Factors that increase the cost
Two projects of the same type can have very different costs depending on these variables. If your project has more than three of these factors, the reference price can be 50–100% higher.
- Integrations with external systems without documented API.
- Strict security and compliance requirements (health, financial sector).
- Complex business algorithms or highly variable pricing logic.
- Multiple user roles with differentiated permissions.
- Advanced analytical reports with large volumes of data.
- Multi-language or multi-currency support.
- Projects where requirements will change during development.

We validate scope, complexity, and integrations to separate a serious estimate from a random number.
Factors that reduce cost
On the contrary, these factors can significantly reduce the investment.
- Very well documented requirements before starting.
- Use already developed libraries or modules (reusable components).
- Start with an MVP instead of the full product.
- Internal team with testing and validation capabilities.
- No integrations with external systems in the first version.
How to read an economic development proposal
A serious proposal distinguishes between development cost (one-time investment), monthly maintenance cost (support, bugs, updates) and infrastructure cost (servers, domain, cloud services). If the proposal does not make that distinction, ask for it before signing.
3-year TCO is the correct metric to compare: initial development + monthly maintenance × 36 + infrastructure × 36.
