ERPs and management systems

Inventory, purchasing, sales and fixed assets in one place, always up to date.

For businesses and institutions with multiple sites

What's included

Inventory, fixed assets, purchasing, sales and management in one place.
Movements between sites (transfers, relocations, loans) with numbered PDF records.
Traceability for every asset or product: where it came from and where it went.
Audit log: who did what, and when.
Audit-ready statistics and reports, exportable to PDF and Excel.
Installed in the cloud or on your company's own server, with no license fees.

You tell me what you need.
A free first conversation, in writing over WhatsApp or email. You only pay once you approve the project.
I show you the solution before writing any code.
You get a written proposal with the scope, timeline and price, plus a mockup so you can see how it will look. What's in the proposal is what gets delivered.
I build it and hand it over.
Every week you see a version you can test. At the end you get the code, the database, the access credentials, the documentation and a user guide.

I work with English-speaking clients in writing — WhatsApp, email and proposals. Calls and meetings are in Spanish.

Commitments

These four points go into the contract for every project.

You talk to the person who writes the code.
No salespeople or middlemen getting what you need lost in translation.
You see progress every week.
A version you can actually test, not just a status report.
The code is yours.
At the end you get the code, the database, the access credentials and the documentation.
A warranty after delivery.
30 days for websites and 90 for systems: I fix any bug in what we agreed on, at no cost. New changes go into a maintenance plan or a separate quote.

Does it work if I have multiple sites?

Yes. The inventory system organizes assets by site and area, and generates reports for each one.

Is there a record of who changed each piece of data?

Yes. Every operation is logged with the user, the action and the date.

Where is it installed?

In the cloud or on your company's own server. The inventory system can run on the client's own server, with no license fees.

A custom web system where every asset is recorded with its site, area and custodian, and every movement leaves a numbered record and an audit trail.
