Fullyn vs Wello Solutions: which is right for Odoo-first companies?
You run Odoo and want to digitize field operations. Wello Solutions may be on your shortlist. Here is an honest comparison — and why architecture changes everything.
Two opposite philosophies
Wello Solutions is a standalone FSM founded in 2008. It runs field operations independently, then syncs to your ERP via a connector.
Fullyn is a native Odoo platform. No connector, no sync, no second system to maintain. Interventions, work orders, time tracking and operator data live directly in Odoo — instantly available for invoicing, payroll and reporting.
The core question: do you want a tool that 'talks to' Odoo, or do you want Odoo to manage the field natively?
Feature comparison
| Feature | Fullyn | Wello Solutions |
|---|---|---|
| Architecture | Native Odoo | Standalone FSM + Odoo connector |
| Double subscription | No | Yes (Wello + Odoo) |
| Field data in Odoo | Instant, native | Via sync |
| Field license | From €8.25/user/month | From €35/user/month |
| Back-office ERP forced on technicians | No | Yes |
| Belgian time-tracking compliance | ✓ | No |
| Vehicle & equipment management (geoloc, engine hours, fuel) | ✓ hardware-agnostic | No |
| All centralized in Odoo (people + machines) | ✓ | No |
| MCP Server / AI agents | ✓ | No |
| Construction & heavy field sector | Specialized | Generic IMR |
The connector problem
Wello says it openly: 'Odoo runs the business, Wello runs the field.' That works for companies without a unified ERP. But if you already use Odoo, a connector creates three real problems.
Extra cost
You pay both Odoo and Wello. At €35/user/month minimum on Wello, a 20-technician team is €700/month of FSM licenses — on top of Odoo. With Fullyn, your field technicians get a mobile interface tailored to their reality from €8.25/month.
Data latency
Sync is not always instant. A job finished at 4pm may not appear in Odoo until the next day — delaying invoicing and skewing your dashboards.
Integration maintenance
Every Odoo or Wello update can break the connector. Your IT team manages two release cycles instead of one.
With Fullyn, the technician completes the job in the mobile app. The work order is updated instantly in Odoo. The invoice can go out the same evening.
What Fullyn does that Wello cannot
One platform to see everything — people and machines in Odoo
This is the heart of Fullyn: a central platform that pushes all field data into Odoo, whether it's your teams or your equipment.
Today many field companies juggle 3-4 tools that don't talk to each other — one for scheduling, one for the car fleet, one for construction equipment, one for time tracking. Each has its own dashboard. Nobody has the full picture. License bills pile up.
Fullyn centralizes everything in one place — your Odoo — so operations managers, planners and directors see exactly what is happening, in real time, without switching tabs.
Vehicle and equipment management — hardware agnostic
On a jobsite, the fleet is more than technician cars. Trucks, lifts, compactors, forklifts, generators, construction equipment — each machine is a real operational cost that nobody really steers, because data is scattered and never tied back to jobs.
Fullyn centralizes everything in Odoo, regardless of brand or tracking hardware:
- Real-time geolocation for every vehicle and machine
- Engine hours — to trigger preventive maintenance at the right time
- Idle hours — to identify fuel waste
- Consumption — fuel per machine, per jobsite, per period
- Alerts — geofence exit, consumption threshold, upcoming maintenance
- Real cost per jobsite — machine + labor, in the same Odoo view
And crucially: hardware doesn't matter. Teltonika GPS, Webfleet, Samsara, OBD dongles, proprietary CAN bus sensors — Fullyn ingests the data and centralizes it in Odoo. You're not locked to a single telematics vendor, and you no longer pay a dedicated platform per equipment type.
Belgian time-tracking compliance
Fullyn integrates work-time recording compliant with Belgian legal obligations, directly tied to field jobs. Data is ready for payroll export — no re-entry, no spreadsheet. Wello has no equivalent for the Belgian market.
Ready for AI agents
Fullyn exposes an MCP Server. Your AI agents can query intervention status, trigger actions and summarize operational reports in natural language. The next step in field automation — Wello isn't there yet.
Coming soon: native tracking module in Odoo
Fullyn is building a tracking module directly inside Odoo — no third-party app, no external dashboard. All vehicle and equipment data accessible from your usual Odoo, in the same views as your jobs, technicians and work orders.

Honestly: Wello is solid in certain contexts. Choose Wello if you don't use Odoo, if you are in classic IMR (HVAC, elevators, energy) without equipment management needs, or if you need an FSM that integrates with SAP, Business Central or Exact Online.
Who is Fullyn the best alternative for?
Choose Fullyn if you already run Odoo or are adopting it, if your teams work in construction, civil works or heavy field, if you manage a mixed fleet — vehicles and equipment — and are tired of paying for several platforms that don't talk to each other, if you must comply with Belgian time-tracking rules, and if you want a single source of truth, accessible from €8.25/month per technician.
Conclusion
Wello Solutions and Fullyn don't address the same profile. Wello was born as a universal FSM that later added an Odoo connector. Fullyn was born in Odoo, for Odoo — and goes further by centralizing machine data in the same platform.
If your stack is Odoo-centric, the question isn't 'which FSM should I connect to Odoo?' but 'how do I make Odoo manage people and machines natively, at the best cost?'
Dirty hands, clean data. That's what Fullyn does — right inside your Odoo.
Frequently asked questions
Does Fullyn replace Wello Solutions?
For Odoo-first companies (or those migrating to Odoo), yes. Fullyn covers field jobs, time tracking, vehicle and equipment management directly in Odoo, with no connector and no double subscription.
Is Wello a bad solution?
No. Wello is solid for IMR companies (HVAC, elevators, energy) on SAP, Business Central or Exact Online. The question is: is your stack Odoo? If so, a native Odoo FSM avoids the connector.
What is the actual price difference?
Wello starts around €35/user/month and forces a back-office interface on technicians. Fullyn starts at €8.25/user/month with a mobile interface tailored for field technicians.
Does Fullyn really handle equipment, not just cars?
Yes. Trucks, lifts, compactors, forklifts, generators, construction equipment — Fullyn ingests data from any hardware (Teltonika, Webfleet, Samsara, OBD, CAN bus) and centralizes it in Odoo.
Do I need to be in Belgium to use Fullyn?
No. Fullyn is used in France, Belgium, Switzerland and the Netherlands. Belgian time-tracking compliance is a plus for Belgian customers, but the platform supports any field operation in Europe.
Can I trial Fullyn before migrating?
Yes. A free demo and pilot deployment are possible. Contact us to assess the migration effort from Wello (or any standalone FSM).
