On specification documents
The framing is deeper than a showcase site: workshops, audit of the existing setup, user journeys, wireframes. Our Odoo web agency does not sign anything without having precisely documented what will be delivered.
Service · Custom Odoo Project · Belgium
Odoo web project, coded to your specifications.
WebNest is the Odoo web agency based in Brussels that handles projects when the standard is no longer sufficient. Custom user journeys, API integrations, dashboards and advanced features coded by hand in QWeb in your instance. Framing by specifications, transparent sprints, recoverable code.
The custom Odoo project, WebNest version
Not just a site, a foundational project.
A custom Odoo web project starts when the standard web module no longer meets the need. As a specialised Odoo web agency in Brussels, we work on specific user journeys, third-party API integrations, live dashboards, and configurators. Three principles guide our approach to custom front-end development.
Advanced Odoo front-end
Scroll animations, interactive configurators, live dashboards, multi-step forms, API integrations: all hand-coded in QWeb, within the web module, without heavy frameworks that hinder performance.
Hybrid front and back
If your project requires custom Odoo backend modules, we collaborate with your integrator or direct you to a trusted partner. The front-end remains the expertise of our agency, in Brussels or elsewhere in Belgium.
Who it is for
Four typical profiles.
Our Odoo web agency supports organisations in Belgium and beyond that have a project too specific to fit into a standard showcase or e-commerce. Here are the four cases we encounter most often.
Complex site with accounts
Registration, login, client area, live dashboards, custom settings. All connected to your Odoo data model, coded in QWeb in the web module.
Custom business journey
Product configurator, price simulator, multi-step quote request, partner area, approval workflow.
Signature experience
Animations, scroll narratives, immersive experiences, mini-games, visual configurator. When the brand demands more than a classic site. For SMEs and brands based in Brussels, Wallonia or Flanders.
ERP plus custom front
Odoo backend workflow connected to a completely rethought front. When the existing ERP needs to open up to the public or clients.
Everything included

Custom project process
Seven steps, no grey areas.
A custom Odoo web project cannot be improvised. The more complex it is, the more important the framing becomes. Here is the 7-step process from our Odoo web agency, punctuated by client validation points at each deliverable.
Discovery and audit
Discovery workshops, audit of the existing Odoo, mapping of user journeys and technical constraints.
Specifications
Detailed document: scope, modules, journeys, integrations, planning, budget. Validated point by point before signing.
Wireframes and UX
Diagrams of key screens, interactive journeys, client validation. We do not code anything until the UX is aligned.
Dev sprints
Development by modules in your Odoo. Each sprint delivers a testable functional block. Code visible 24/7.
Iterative testing
You test each sprint as you go. Adjustments are integrated directly into the next sprint.
Final acceptance
Overall project acceptance, end-to-end journey, performance, accessibility. Zero finish list before delivery.
Delivery and training
Go live, technical documentation provided, 1 to 2 hours of training via video on editable areas. Source code recoverable.

Custom project questions
All about the custom Odoo project.

-
Why choose an Odoo web agency for a custom project?
An Odoo web agency like WebNest mobilises a team specialised solely in Odoo: front-end, design, QWeb integration, client follow-up. For a custom project (configurator, member area, dashboard), this secures deadlines, code quality, and maintainability. A freelancer may suffice for a simple site, but for a business project, the agency provides a proven production framework. -
How long does it take to deliver a custom Odoo web project?
Variable depending on complexity: from 1 month for a simple project to 4 or 5 months for a more ambitious project. The precise duration is fixed in the specifications, after the discovery phase.No duration commitment before signing the specifications. -
Does WebNest support projects outside Brussels?
Yes. WebNest is based in Brussels but delivers custom Odoo web projects all over Belgium, France, Luxembourg, and beyond. Everything is done via video call and through your Odoo instance, so distance does not affect the quality of support. The site can be translated into any language: in the team, we speak FR, NL, and EN. -
Do you work with my Odoo backend developer?
Yes, that is quite common. If you already have an Odoo backend integrator managing your custom modules, we align with the data model and take care of the entire front end. Direct coordination without intermediaries. -
Do you manage third-party API integrations?
Yes, as an option. We code the connectors on the front end (read/write REST API) or assist with the setup of Odoo webhooks. For heavy backend integrations, we collaborate with an Odoo Python developer. -
Do I get the source code at the end of the project?
Absolutely and automatically. Everything is coded inyourOdoo, so everything belongs to you from the first line. Technical documentation is provided upon delivery. If you change agencies one day, the code remains maintainable by any Odoo developer. -
How do sprints and billing work?
40% deposit upon signing the specifications. Development sprints by functional blocks with a client validation point at each deliverable. Balance due at final delivery. If the scope changes during the project, an amendment to the quote, no surprises. -
Do you do purely Odoo back-end projects?
No. WebNest is100% specialised in Odoo front-end.. If your project is solely backend (business modules, Python automations, ETL), we will direct you to a trusted Odoo backend integration partner. No margin on this referral.
Shall we start the framing?
30 minutes, we assess your custom project.
You explain your needs and constraints, and we tell you if Odoo is the right foundation and how we would approach it. No commitment, no sales follow-up afterwards.
