Custom web systems
We build custom web systems for Peruvian companies that have outgrown spreadsheets or off-the-shelf software that doesn't fit how they actually operate.

Custom software that actually reaches production
We build web systems and integrations for Peruvian companies. And we don't just say it: Invoicing Data and Mi Tiendita are our own platforms, with real customers invoicing every single day.

What we do
Four ways to work with us
Integrations and APIs
We connect your system to SUNAT, payment gateways, or other software you already use through integrations and APIs, so you stop moving data by hand between platforms.
Technology consulting
We give you a second technical opinion on a system, a vendor proposal, or an architecture decision, based on what we've actually built and operated, not theory.
AI and automation
We automate manual processes, build assistants that answer from your own documents, and create agents that carry out tasks: classify, log, reply, and escalate.
Our products
Proof that we know how to build software

How we work
From first conversation to production
- 01
Diagnosis
A session to understand your operation and what hurts today. We come out with the problem written down and prioritized, not a feature list.
- 02
Fixed-price proposal
Scope, timeline and price in writing before we write a line of code. No "it depends" and no open-ended budgets.
- 03
Development in increments
Deliveries every two weeks that you can use and comment on. You watch the system progress instead of waiting months for a launch.
- 04
Production and support
We put it into production, train your team, and stay on to support the first months of real-world use.
Why us
Four verifiable reasons
We run what we build
We don't hand off a system and disappear. Our own platforms have been in production for years with customers invoicing every day, so we know exactly what it costs to keep software alive — and we plan for that from day one of your project.
We know Peruvian regulation from the inside
SUNAT, SIRE, RVIE, RCE, electronic invoicing. We didn't just read the documentation: we implemented it and keep it current every time the regulation changes.
Small team, direct contact
There are four of us. You talk to the person writing the code, not an account manager relaying what you said.
No black boxes
The code, the documentation and the access credentials are yours from the start. If you ever decide to work with another provider, you can.
Frequently asked questions
What people ask us most
How much does a custom system cost?
It depends on the scope, but we always agree on a fixed price before starting. A small internal system starts at a few weeks of work; an ERP with SUNAT integration takes several months. In the diagnosis session we give you a realistic range with no commitment.
Do you work with companies outside Tacna?
Yes. We're based in Tacna and serve customers across Peru remotely. Our products also operate in ten Latin American countries.
Is the code mine?
Yes. The code, the documentation and every access credential are yours from day one. We don't use licenses that lock you in or withhold credentials.
Can you integrate my current system with SUNAT?
Yes, it's one of the things we do most. We already run electronic invoicing and SIRE in production with Invoicing Data, so we know the edge cases the official documentation doesn't cover.
What happens if I need changes after delivery?
We offer ongoing support and evolution. You can contract it by the hour or with a monthly agreement, depending on how often your system changes.
Why should I trust a four-person team?
Because you can verify what we do. Invoicing Data and Mi Tiendita are our own products, public and in production, with more than a hundred companies and two hundred thousand documents a year. It's not a portfolio: it's software running right now.
