— The complete stack

From quote to handover.
Eight apps. One database.

Portuguese architects and construction SMEs juggle Excel, AutoCAD, email and PHC. Odoo replaces the patchwork with a connected platform — every project, drawing, supplier and invoice on the same database.

01 · Plan Win the project. From first lead to signed contract — quote, schedule, contract, all in one flow.
Core

Project

Multi-stage projects, dependencies, milestones, Gantt & Kanban views, real-time progress.

Sales / Quotation

BOQ-style quotes, templates with 3D renderings & CAD attachments, e-sign approval.

Planning

Resource allocation, recurring shifts, role-based scheduling, workload heatmaps.

02 · Build Execute on time, on budget. Procurement, hours and drawings — connected to the live project budget every day.

Purchase

Subcontractor management, RFQs, materials POs linked to projects & budgets.

Documents

DWG, IFC, RVT, BIM PDFs, contracts, permits — versioned next to each project, searchable.

Timesheets

Mobile time tracking by project & phase. Auto-billing for time & materials engagements.

03 · Operate Hand over and keep the relationship. Sign-offs, progress invoicing, warranty interventions — the post-handover phase, organized.

Sign

Native e-signature on contracts, change orders, handover certificates. AT-compliant.

Field Service

Post-handover interventions, snag list, warranty work — all tied back to the project.

Accounting

Progress billing, retention, intercompany invoicing. SAFT-PT & e-Fatura, AT-certified.

— Built for your legal structure

One SPV per project?
Native, not a plugin.

Most Portuguese construction firms run a holding plus one sociedade veículo per major project — for tax, risk, financing. PHC and Primavera charge per company. Odoo Enterprise ships multi-company natively, with auto-consolidation between entities.

Unlimited entities

One SPV per project, one holding. Group structure mirrored 1:1 in Odoo, on the same database.

Auto-consolidation

Intercompany invoices, rules and consolidation reports out of the box. Group P&L always live.

Cost-neutral

No extra license per company. Add an SPV in 5 minutes. Remove it just as fast at project end.

— Spotlight: Project Gantt

Every project. Every dependency. One screen.

Odoo Project's Gantt is the command center for architecture and construction firms. Drag a task to reschedule, see dependencies cascade, spot resource conflicts before they cost you. Every change updates the budget & profitability views in real time.

  • Multi-project GanttDrag-drop tasks across phases. Dependencies enforced. Critical path highlighted automatically.
  • Milestone billingEach milestone triggers an invoice. Progress payments tracked against the contract value.
  • Resource levelingSee who's overbooked. Reassign tasks with a drag. Avoid the 110%-load surprise.
  • Real-time profitabilityTimesheet hours, vendor bills, expenses — all aggregated against the project budget. Live margin per project.
  • Mobile for the siteSite managers update progress, log expenses, scan deliveries from their phone. No paperwork.

— Real capabilities, not buzzwords

What you actually get out of the box.

No construction module sold separately. No add-on for progress billing. Standard Odoo Enterprise covers the whole project lifecycle.

01

Multi-stage projects

Phases, sub-tasks, dependencies, milestones. Nest a renovation under a parent build. Mirror your real workflow.

02

BOQ-style quotation

Templated quotes with 3D renders, floor plans, line items priced from your catalogue. Send. E-sign. Convert to project — automatically.

03

Progress billing

Milestone-based, % completion, retention amounts. Invoice partial work without manual cycles. Cash flow stays predictable.

04

Subcontractor management

Each subcontractor PO linked to a project line. Track payment terms, retention, performance. No more lost POs in email.

05

Timesheets & auto-invoicing

Mobile time logging by project & phase. Hours flow straight into invoices for T&M contracts. Billable vs non-billable separated.

06

Document control · CAD & BIM

DWG, IFC, RVT, BIM PDFs, contracts, permits — versioned next to the project. Odoo doesn't replace AutoCAD or Revit — it organizes everything around them, with e-sign and search built in.

— Now · Odoo AI agent

An AI agent on every project.

Odoo's native AI agent reads project data, timesheets, vendor bills and contracts in the same database. It answers questions in plain Portuguese — no integration project, no separate vendor.

01 · Project margins on demand

Profitability without spreadsheets.

Live data on every open project. The agent crunches it instantly, in your language.

Qual é a margem real do projeto Lisbon Tower até hoje? Mostra-me a evolução semana a semana.
02 · Budget alerts

Catch overruns at 80%, not 100%.

The agent watches timesheets and vendor bills against the project budget. Alerts before you blow the line.

Os timesheets do projeto Vila Nova ultrapassam 80% do orçamento — alertar o gestor?
03 · Resource conflicts

Know who's overbooked.

Looks at planning + timesheets to spot conflicts and propose reallocation across projects.

Estes 3 subcontratados estão sobrecarregados na próxima semana. Sugere realocação?
04 · Contract intelligence

Search clauses across all contracts.

Reads PDFs & signed docs in your Documents app. Surfaces obligations, deadlines, penalties.

Resume os contratos assinados este mês com cláusulas de penalização por atraso.
