END-TO-END DIGITAL TRANSFORMATION

ERP Pulpo

How I moved a company with no technology, coordinated by phone and WhatsApp, into a custom system that reveals the real profitability of each job and manages operations with far fewer steps.

Management system developed around a real operation.
01 — THE STARTING POINT

A company that worked
without knowing exactly how.

There was no website, database or management tooling. Activity was coordinated through calls and messages, reports ended up in a binder and the numbers were calculated by eye.

The company had knowledge, experience and an established way of working. What it did not have was a way to turn all that activity into reliable information. After a service, it was very hard to answer a question as basic as it was important:did this bar make or lose money?

I decided to get involved and build a system from the inside. Before programming, I had to understand the jargon, product conversions, shrinkage, costs, commissions, routes and exceptions that only the people in the business knew.

01Paper reports

Information was filed away, but it could not be analyzed.

02Phone and WhatsApp

Coordination depended on scattered conversations.

03Back-of-the-envelope calculations

There was no consistent calculation of revenue, expenses and profit.

04Personal knowledge

Business rules lived in the experience of a few people.

FIRST VERSION

Digitize first.
Never make it complicated.

The first solution had to be usable by anyone without technical training. That is why I built the whole flow on familiar Google tools: simple on the outside, with substantial business logic inside.

FULL FLOWFrom paper report to data-based decision
First-version flow: a paper report is entered into Google Forms, goes to Google Sheets, is normalized and feeds automations, an operations dashboard and Looker Studio.
01

Structured capture

Google Forms replaced free transcription with a guided process. Responses always arrived with the same structure and could be connected to clients, teams, vehicles and dates.

02

A truly useful base

The input sheet fed a second normalized base. There, data was cleaned, equivalences were applied and only the information needed to calculate and decide was gathered.

03

Business rules

The system incorporated the specific formulas for product, shrinkage, portions, revenue, expenses, wages, fuel and commissions. It also detected inconsistent data so it could be reviewed.

04

Control by job

From the dashboard, each digitized report could be opened, checked and summarized with the estimated profit or loss of that service.

05

CRM and routes

The same structure evolved to store commercial information about bars and prepare routes for the pulperos, connecting dates, teams, vehicles and destinations.

06

Executive view

Looker Studio turned all that information into an executive view. For the first time, the company could work with consistent figures instead of approximations.

WHAT CHANGED

The company went from not knowing precisely how much each job earned or cost to having a shared base, digitized reports and an economic reading of the activity.

SECOND VERSION · CURRENT

A custom ERP.
The same simplicity.

With the growth of artificial intelligence and assisted-development tools, I decided to rebuild the system. The new architecture expands what the business can do while reducing the effort required to use it.

NEW REPORTING FLOWA photo starts the whole process
Current-system flow: a photo sent through WhatsApp reaches OpenClaw, goes through OCR and human review, then is processed in Django, stored in PostgreSQL and generates operational outputs.
ONE SINGLE INPUT FEEDS
Financial control

Revenue, expenses and profit by job.

CRM

History and real context for each client.

Budgets

Scenarios and break-even point before accepting.

Operations

Teams, vehicles, product and resources.

Coordination

Calendar, sales activity and connected communication.

A COMPLETE INTERFACE

Power when needed.

The web app makes it possible to review reports, consult dashboards, manage clients, prepare budgets, administer people, vehicles, products and costs, and keep a reliable history of every change.

WHATSAPP AS THE ENTRY POINT

Simplicity for everyday use.

Most common queries and tasks can start from WhatsApp: sending a report, checking information, making an estimate or coordinating. The system processes the request and returns the answer through the same channel.

A CONNECTED ECOSYSTEM

Information that flows.

The ERP connects with the calendar and coordination systems to share information between management, sales and teams, as well as supporting tasks such as posters and communications.

03 — THE RESULT

From one hour each weekend
to a few seconds per report.

10–12usual reports each weekend
4 minper report in the previous form
20 sto photograph and send now
≈92%less time spent recording each report

Before, reports were filed away without creating a shared view. Later, entering them in Google Forms took around four minutes per document: nearly an hour of work every weekend. Now it is enough to take a photo and send it through WhatsApp.

The time saving matters, but the most valuable change is something else: every report feeds a system that helps understand the economic reality of the company, anticipate decisions and coordinate people better.

04 — WHAT THIS PROJECT PROVES

I did not start by choosing technology.
I started by understanding the business.

01

Consulting

Entering an unfamiliar operation, listening, asking questions and discovering where time and information are lost.

02

Process design

Turning conversations, exceptions and manual calculations into a flow the whole team can understand.

03

Engineering

Choosing a solution proportional to the moment and evolving it from Google Sheets to Django, PostgreSQL and agents.

04

Adoption

Building around people, integrating the system with tools as everyday as WhatsApp.

DO YOU HAVE A SIMILAR PROCESS?

You may not need “more software”.
You need the right system.

If your company depends on scattered sheets, messages or manual calculations, I can help you understand the problem and build a solution the team will actually use.
