Since 2017
Consulting and development for companies in every industry in Peru.
How we work
Scope, timeline and price in writing before a line of code.
Five phases, the same for a custom system as for an ERP. If the scope changes along the way we say so and requote — it doesn't turn up on the final invoice.
1. Assessment
We start by looking at how you work today, spreadsheets included. That's where the scope comes from — and also what we shouldn't build, because something you already own solves it.
2. Fixed proposal
Scope, timeline and price in writing before a line of code is written. If the scope changes later we say so and requote; it doesn't show up on the final invoice.
3. Phased delivery
Working software arrives in parts, not all at the end. What goes live first is whatever hurts most today, so the system starts paying off before it's finished.
4. Go-live and training
We migrate the data you already have and train the people who will use it. A system the team can't use is a system that's back in Excel within three weeks.
5. Support
We stay on after handover: fixing issues, making changes and adding features as the operation evolves.
API platform
Public bodies don't publish APIs. We do.
Validating a tax ID, a plate or a REINFO record means opening each authority's portal and reading it by hand. Here it is one HTTP request, with the same authentication and the same response shape for every source.
Sources integrated today
- SUNAT tax ID, taxpayer status and exchange rate
- MTC carrier registry, certificates and plates
- MINEM REINFO, mining formalisation

One integration, every source
The same authentication and the same response shape for every lookup. Integrate once and add sources without touching your code.
-
We deal with the paperwork
Public bodies don't publish APIs: their portals have to be read. When they change the HTML, we fix it and your integration keeps working.
-
You don't pay twice for the same data
Lookups whose data doesn't change daily are served from cache. Repeating a recent lookup doesn't count against your plan.
-
Usage control and audit trail
Per-application tokens, per-plan quota and a record of every lookup: what was asked, when, and what came back.
-
Missing the one you need?
We integrate new sources on request. If your process depends on a public portal, we can turn it into an endpoint.
-
We run on it too
Our own ERP uses this platform to validate tax IDs, plates and registrations. It isn't a product we sell without using.
From the coast to the jungle
We work across all of Peru.
Pesu crosses the coast, the highlands and the jungle. The system gets installed, maintained and supported wherever your company is.
More than a lookup
We build the whole system too.
The API answers one question. When what's missing is the ERP that data feeds, the invoicing that issues it or the app it's queried from, we build that too.
