PROBLEMS WE SOLVE
We start from the real context of your business to understand what should be resolved first.
LACE
You adapt your processes to functions that were not designed for your business.
DISPERSION
Each department stores a portion of the information in a different tool.
GROWTH
New users, locations, or lines of business need a more solid foundation.
CONTROL
It's difficult to know which version of a piece of data is correct and who can modify it.
DEPENDENCIES
The customizations of the current tool do not cover what you need.
CONTINUITY
You have your own software, but maintaining it or adding features is becoming increasingly complex.
WHAT WE DO
We agree with you on the priorities and scope so that each delivery responds to a specific need.
Planning equipment, availability, materials and operations in a shared application.
Budgets, orders, and billing workflows tailored to your existing rules and systems.
Private areas to consult information, send requests and track the status of each process.
Web tools that collect your processes, permissions, and needs for each user profile.
We connect the application to your systems and prepare the migration of the necessary data.
We expand or modernize existing applications with a change and continuity plan.
WHY WALLION
We work with you to define how the application should function, build the solution, and support its implementation. Each feature addresses a specific business need.
We understand the context. We review objectives, constraints, and people involved before proposing a solution.
We agreed on the scope. We clearly defined the responsibilities, priorities, and conditions of collaboration.
We support the execution. We share progress, decisions, and next steps with your team.
SCOPE
Objectives, deliverables, and written validation criteria.
DELIVERY
Joint reviews to verify that the work meets the agreed terms.
RESPONSIBLE
Direct communication and shared context during collaboration.

HOW WE WORK
01
We review processes, users, and data to understand what the application needs to solve.
02
We agreed on functionalities, integrations, phases, and acceptance criteria.
03
We build in stages and validate the routes with the people who will use the application.
04
We launch the application and agree on its maintenance and upcoming changes.
WHERE IT FITS
A custom application makes sense when your processes and rules need a fit that standard solutions don't offer.
01
The way you work adds value and needs to be maintained.
02
We know who will use the application and what they need to achieve.
03
We can separate what is essential from subsequent improvements.
