The ERP that bends to your business. Not the other way around.
Enterprise-grade ERP on a proven open-source core, a portal for every role and customization that commercial systems charge a fortune for, at a price they simply cannot match. Built around how your company really works.


Spreadsheets, three apps and a whiteboard are running your company.
a week lost to spreadsheets
Ten people losing three hours a week rebuilding, copying and checking the same numbers. An illustrative estimate; your own number comes from your team's answers.
real-time view of profit
You find out a job lost money weeks after it closed, when nothing can be done about it.
logins for one job
Quotes in one tool, calendar in another, photos in a phone, invoices in accounting. Nothing talks to anything.
Everything you expected from an ERP. Nothing you expected to pay.
Commercial ERPs sell you a template and charge you to bend it. We start from your process and build the system around it.
| Typical commercial ERP | Vellron | |
|---|---|---|
| Licensing | Pay per seat, every new hire costs more | Simple size bands: we grow only when you grow |
| Changing a screen or a rule | Change request, consultant, months | Days: built for your process, not a template |
| Field crews on the phone | Extra app, extra subscription | Included: same system, same login |
| Customer and supplier portals | Add-on products or not available | Included and connected to the ERP |
| Training your people | Classroom days or PDF manuals | Videos and quizzes inside the system |
| Your data | Locked in the vendor's cloud format | Open-source ERP core, full export, yours |
| Who you talk to | A ticket queue | The people who built your system |
Every department, one login, one source of truth.

Know a job is losing money while you can still fix it.
Sold, planned cost, executed cost, invoiced and received, live on every job. When a job drifts below target, the right manager is told the same day.

Each person opens on what needs them today.
Approvals waiting, change orders to decide, timesheets to approve: every role sees its own work first, with live numbers per area.

"Most systems fail because they copy a vendor template instead of the way your crews, office and sales team actually work. We start with the work."
Paulo Cangussu, founder
