Odoo project management module is not a standalone task tracker. It connects tasks, timesheets, and billing to sales, accounting, and expenses on one database. This guide explains how a project flows from quotation to invoice, where profitability is tracked, and what you should test before committing to the module.
📋 Key Takeaways
- Odoo project management handles tasks, stages, timesheets, deadlines, and team assignments, and its real value is the live connection to Sales, Accounting, Purchase, and Expenses.
- Three billing models are supported. Bill by hours logged, by milestone completion, or by a fixed contract value.
- Profitability updates in real time. Revenue from invoices minus cost from timesheets, vendor bills, and expenses, shown per project.
- Timesheets drive both billing and cost. Time multiplied by the billing rate is the invoice, and the same time multiplied by an internal rate is project cost.
- For service businesses, the module replaces standalone tools that cannot raise invoices or track profitability.

What Odoo Project Management Covers
Odoo project management brings five capabilities together so delivery, time, and money live in one place.
- Task management. Create, assign, prioritise, and track tasks with deadlines, tags, and subtasks.
- Kanban stages. A visual workflow such as To Do, In Progress, Review, and Done, customisable per project.
- Timesheets. Employees log hours against tasks, and that time feeds both billing and cost.
- Project billing. Invoices are generated from timesheets, milestones, or fixed price contracts.
- Profitability. Revenue against cost per project, per task, and per team member, updated as entries post.
- Integration. Connected to Sales where quotations create projects, to Odoo accounting configuration for invoices and cost entries, to Purchase for vendor costs, and to Expenses for claims.
Projects, Stages, and Task Workflows
How task management works
- Projects. Each project has its own task list, stages, team, and settings. A consulting engagement, a website build, and an implementation are three separate projects.
- Stages. Customisable kanban columns. The default set is New, In Progress, and Done, and you can add Review, Waiting for Client, or QA.
- Tasks. Created manually, from a sales order, or from a template. Each task carries an assignee, deadline, priority, tags, subtasks, and a chatter thread for comments.
- Subtasks. Break complex tasks into smaller steps. Each subtask tracks its own time and assignee but rolls up to the parent task.
- Recurring tasks. Monthly reports, weekly reviews, or quarterly audits are created automatically on a schedule.
Timesheets and Capacity
Time tracking that drives billing and cost
- Logging time. Employees log hours against tasks from the Timesheet module, the task form, or a timer widget, and it works on mobile.
- Approval workflow. Managers approve timesheets weekly. Unapproved time does not flow to billing, which prevents unbilled or unreviewed hours.
- Employee cost rate. Each employee has an internal cost per hour. When they log time, the cost is calculated automatically and feeds the cost report.
- Billing rate. The rate is defined on the sales order line. When the customer is invoiced, Odoo multiplies approved hours by the billing rate.
- Capacity planning. See how many hours each member is allocated across projects, and spot overloaded or underutilised resources.
Linking Projects to Sales Orders
The flow from quotation to project turns a signed deal into delivery work without rekeying, a pattern seen across most Odoo implementation services engagements.
The quotation to project flow
- Step 1. Create a quotation. Add a service product such as Consulting Hours or Implementation Project, then set the billing method as by timesheets, by milestones, or fixed price.
- Step 2. Confirm the sales order. Odoo automatically creates a project, or links to an existing one, and generates tasks based on the service lines.
- Step 3. Work happens. Team members log timesheets against the tasks, and milestones are marked complete as deliverables are accepted.
- Step 4. Invoice. Timesheet billing pulls approved hours at the agreed rate, milestone billing triggers when a milestone is marked done, and fixed price billing follows the payment schedule.
Because the project is born from the sales order, the scope you quoted and the work you deliver stay tied together. A realistic Odoo implementation timeline assumes this link is set up early.
Project Profitability in Real Time
Where project revenue comes from
- Timesheet invoices, calculated as hours multiplied by the billing rate.
- Milestone invoices, a fixed amount per accepted deliverable.
- Fixed price contract invoices, raised on a schedule.
Where project cost comes from
- Timesheets. Employee hours multiplied by the internal cost rate, logged when timesheets are approved.
- Vendor bills. Subcontractor or vendor costs tagged to the project through analytic accounting.
- Expenses. Employee claims such as travel, materials, and subscriptions, allocated to the project.
- Purchase orders. Materials or services bought specifically for this project.
Profitability is revenue minus cost, updated with every posted entry. There is no month end compilation and no spreadsheet aggregation, so the manager sees margin in real time and can act before a project goes over budget.
Billing Models in Odoo Project Management
Model 1. Timesheet based billing
- Employees log hours, and the customer is invoiced for approved hours at the agreed rate.
- This suits consulting, advisory, and support work where scope is fluid and time is the deliverable.
- Revenue is variable because it tracks actual effort. Many Odoo ERP for small business teams start here.
Model 2. Milestone based billing
- Milestones are defined on the sales order, and an invoice is triggered when one is marked complete.
- This suits implementation projects, website builds, and engagements with defined deliverables.
- Revenue is fixed per milestone because scope is locked for each deliverable.
Model 3. Fixed price billing
- The total price is agreed upfront and invoiced on a schedule, for example thirty percent on signing, forty percent mid project, and thirty percent on completion.
- This suits retainer contracts, annual service agreements, and packaged services with predictable scope.
- Revenue is predetermined, so profitability depends on how efficiently the team delivers.
Connecting Projects to Purchase and Expenses
- Purchase orders. When a project needs external resources such as a subcontractor, equipment rental, or a software licence, the purchase order is tagged with the project analytic account so the cost appears in the cost report.
- Employee expenses. Travel, meals, and materials bought by team members are submitted as expense claims, approved, and posted to the project analytic account.
- Vendor bills. Any vendor invoice tagged to the project, including freelancer invoices, hosting, and printing, flows to the project profit and loss view.
- Analytic accounting. Every cost line references the project analytic account, and that is how Odoo aggregates all revenue and cost into one view per project.
Collaboration and Approvals
- Chatter. Every task has a message thread. Comments, attachments, and status updates are logged with timestamps and user attribution.
- Followers. Stakeholders added as followers get email notifications on updates. Clients can join as portal users to see progress without back office access.
- Customer portal. Clients log in to view their project, check task status, download deliverables, and approve milestones, which removes most status emails.
- Timesheet approval. Managers review weekly, unapproved timesheets are flagged, and only approved time flows to billing.
Dashboards for Project Health
What project managers see
- Task status overview. How many tasks sit in each stage across all projects, so bottlenecks are visible at a glance.
- Timesheet analysis. Hours logged per employee per project per week, showing who is overloaded and who has capacity.
- Profitability dashboard. Revenue against cost per project, margin percentage, and the trend over time, with projects near breakeven flagged.
- Burndown view. Remaining work against time remaining, showing whether the project is on track for the deadline.
- Billing status. Hours logged but not yet invoiced, and milestones completed but not billed, so nothing is missed.
Where Standard Project Flows Need Extension
⚠️ Standard configuration limits
- Resource scheduling. Odoo shows capacity but does not optimise scheduling across projects for minimum conflict. Complex allocation across many projects often needs Odoo customization services or a third party tool.
- Gantt dependencies. The Gantt view supports basic task dependencies, but critical path and strict sequencing need extra configuration.
- Client approval workflows. The portal shows task status, yet a structured multi stage client sign off with tracking may need a custom workflow.
- Complex billing rules. Blended rates, where team members bill at different rates on one project, need careful sales order structuring or custom logic.
- Project billing across entities. A project delivered by one company but billed by another needs inter company handling, where Odoo consulting services are recommended.
What to Test in an Odoo Project Management Demo
Five things to validate
- Quotation to project. Create a quotation with a service product, confirm it, and verify a project and tasks appear automatically.
- Timesheet to invoice. Log timesheets, approve them, create an invoice, and verify the amount equals approved hours multiplied by the rate.
- Cost capture. Add a vendor bill and an expense, then check both appear as project costs alongside timesheet cost in the profitability report.
- Milestone billing. Mark a milestone complete, create a milestone invoice, and verify the correct amount is billed.
- Single screen view. Open the dashboard and confirm revenue, cost, margin, unbilled hours, and task status are all in one place.

It manages tasks, stages, timesheets, and billing, and connects to Sales for quotations, Accounting for invoicing, and Purchase and Expenses for cost tracking. Profitability is visible per project in real time on one database.
Yes. Revenue from invoices is compared against cost from timesheets, vendor bills, and expenses. Profitability is shown per project, per task, and per employee, updated with every posted entry.
Employees log hours against tasks. Approved timesheets link to a sales order line that carries a billing rate, and the invoice multiplies approved hours by that rate. Three models are supported, timesheet based, milestone based, and fixed price.
Yes. Invoices post revenue. Employee time posts as project cost through analytic accounting. Vendor bills and expenses tagged to a project appear in the cost report, all on one database.
Yes. Service firms that sell time and deliver projects use it as their operational core. The link to Sales, Timesheets, Invoicing, and Expenses replaces standalone tools that cannot raise invoices or track margin.
Analytic accounting tags every cost and revenue line to a project. Timesheets, vendor bills, purchase orders, and expenses reference the same analytic account, which lets Odoo aggregate them into one view per project.
Common gaps are cross project scheduling, detailed task dependencies and critical path, structured client sign off, blended billing rates, and inter company billing. These usually need configuration or a custom view rather than standard settings.
