To budget 2027, custom software in Peru costs between S/ 3,000 and S/ 150,000 to build depending on the project type: a landing page with a quote form, S/ 3,000 – 8,000; a web platform, S/ 15,000 – 50,000; a mobile app, S/ 25,000 – 80,000; and a custom ERP, S/ 40,000 – 150,000. Add 15% to 25% of the build cost per year for maintenance, plus infrastructure and, if the system uses AI, model usage.
Why you should budget 2027 software now
Most companies in Peru close next year's budget between October and December. If the system you need is not in that line item, the project slips by half a year: first you ask for more budget, then you get quotes, and only then you start.
The problem is that almost nobody has a reliable figure at that point. This guide gives you reference ranges by project type, what changes compared with 2026, and a simple way to turn those ranges into an annual budget line your management can approve.
Price ranges by project type for 2027
The ranges assume an experienced development team in Peru and include requirements gathering, design, development, testing and deployment. They do not include maintenance or infrastructure, which are separate lines (see below).
We do not expect these ranges to drop in 2027. AI speeds up part of the coding, but most of the cost is in understanding the process, integrating systems and testing with real users, and none of that has become cheaper.
For a range tailored to your case, use the software budget calculator or book a call and we will give you a reference range within 48 hours.
| Project type | Build (S/) | Typical timeline | What it includes |
|---|---|---|---|
| Landing page + quote form | 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 | App in both stores, own API, notifications |
| Custom ERP (own modules) | S/ 40,000 – 150,000 | 4–9 months | Inventory, purchasing, sales and finance integrated |
| Chatbot or AI agent | S/ 8,000 – 40,000 | 4–10 weeks | WhatsApp or web, generative AI, CRM connection |
| Systems integration | S/ 5,000 – 25,000 | 3–8 weeks | APIs, data sync, automations |
What changes in 2027 compared with 2026
Build costs stay the same, but the makeup of the budget is changing. These are the changes we see in the projects we are quoting for next year.
- AI goes from extra to requirement: more and more projects include an assistant, automatic classification or an agent that answers on WhatsApp. That adds build cost and, above all, a monthly model usage cost.
- More costs in dollars: cloud, AI models and the WhatsApp API are billed in dollars. Budget those lines in dollars or with an exchange-rate margin.
- Integrations weigh more than screens: connecting to SUNAT, payment gateways, the existing ERP or CRM is usually the most uncertain part of the project. Ask for the quote to list them one by one.
- First-release timelines get shorter: with AI-assisted development tools, a well-scoped MVP ships sooner. Use that to launch with less scope and expand with real data, not to cram more into phase 1.

How much to set aside beyond the build
The most common budgeting mistake is approving only the build. The system starts costing money the day it goes live, and those lines must be in the annual budget from the start.
| Budget line | Annual reference | What it covers |
|---|---|---|
| Maintenance and support | 15% – 25% of the build | Bug fixes, adjustments, security updates |
| Infrastructure | S/ 1,200 – 12,000 | Servers or cloud, database, domain, backups |
| AI usage (if applicable) | Depends on volume | Calls to the AI model; grows with the number of conversations |
| Evolution | 10% – 20% of the build | Improvements users will ask for once they use the system |
How to build the software line in your 2027 budget
Management approves a figure that explains itself faster. With these five steps you reach a defensible number before getting a detailed quote.
- Write in one line the process the system must solve and what doing it by hand costs today (team hours, errors, lost sales).
- Place the project in the range table and take the midpoint, not the minimum.
- Add 15% to 25% annual maintenance, infrastructure and, if it uses AI, an estimate of usage.
- Split the investment into phases: MVP in the first half and evolution in the second. That way spending follows results.
- Keep a 10% to 15% contingency for integrations that turn out more complex than expected.
Example: annual budget for a web platform
A services company wants to replace its order spreadsheets with a web platform with roles, reports and a connection to its electronic invoicing. The amounts are illustrative: each vendor must give you the real ones in writing.
MVP build in the first half: S/ 30,000. Evolution in the second half: S/ 6,000. Maintenance from go-live, six months at S/ 600: S/ 3,600. Infrastructure for the year: S/ 3,000. 10% contingency: S/ 4,260. Total line for 2027: S/ 46,860.
That is the number to bring to the budget meeting, not the S/ 30,000 build. From 2028 the recurring cost is only maintenance, infrastructure and whatever evolution you decide on.
When to ask for a quote to be on time
If you want to start in the first quarter of 2027, ask for the quote before your budget closes. A serious vendor needs one or two meetings to give you a reliable range, and that range is what you need to get the line approved.
Bring to that meeting the process as it happens today, who will use it, which systems it must connect to and what must work in the first release.

Frequently asked questions
- How much does custom software cost in Peru in 2027?
- Between S/ 3,000 and S/ 150,000 to build depending on the project type: a landing page with a quote form, S/ 3,000 – 8,000; a web platform, S/ 15,000 – 50,000; a mobile app, S/ 25,000 – 80,000; a custom ERP, S/ 40,000 – 150,000. Add 15% to 25% per year for maintenance, plus infrastructure.
- Will software prices drop in 2027 because of AI?
- Not significantly. AI speeds up part of the coding and shortens MVP timelines, but most of the cost is in understanding the process, integrating systems and testing with users, and that stays the same. Where you can save is by launching sooner with less scope.
- How much should I set aside for maintenance?
- Between 15% and 25% of the build cost per year, plus infrastructure. If the system uses AI or WhatsApp, add the monthly usage of those services, which is billed in dollars and grows with use.
- How do I present the project to get the budget approved?
- With the current cost of the process (hours, errors, lost sales), the total first-year cost — build, maintenance, infrastructure and contingency — and a phased plan: MVP in the first half and evolution in the second.
- How do I get a figure for my 2027 budget?
