Key Takeaways
- Odoo connects project delivery directly to billing for real-time profitability visibility
- Three billing models supported natively: fixed-price, time-and-materials, and retainer
- Resource planning shows consultant availability and utilization across projects
- Approved timesheets flow automatically to both payroll and client invoicing
- Project profitability dashboards flag budget overruns before they become critical
Billing Model Configuration
Professional services firms typically use three billing models, each requiring different revenue recognition and invoicing workflows. Odoo supports all three natively through project type configuration.
| Billing Model | Revenue Recognition | Invoice Trigger | Best For |
|---|---|---|---|
| Fixed Price | Milestone completion | Milestone delivery | Well-defined scope projects |
| Time & Materials | Timesheet approval | Approved timesheets | Advisory, consulting engagements |
| Retainer | Monthly allocation | Monthly cycle | Ongoing support contracts |
Many engagements combine models. A strategy project may have a fixed-price discovery phase followed by T&M implementation. Configure these as separate project phases with different billing rules.
Timesheet Management and Billing
Timesheet accuracy drives both revenue capture and profitability analysis. Configure Odoo to make time entry simple for consultants while maintaining the detail needed for client billing.
- Consultant logs time against specific project tasks with activity descriptions
- Manager reviews and approves timesheets weekly
- Approved billable time generates draft invoices automatically
- Invoices include configurable detail: date, consultant, task, hours, rate
- Approved timesheets also feed payroll for accurate labor costing
Set minimum billing increments (typically 15 or 30 minutes) in the project settings. Configure different billing rates per consultant, project, or activity type. Rate cards ensure consistent pricing across proposals and invoicing.
Resource Planning and Utilization
Resource utilization is the primary profitability driver for professional services firms. Odoo's planning module provides visibility into consultant allocation and availability.
| Utilization Range | Status | Action |
|---|---|---|
| Below 60% | Under-utilized | Assign to new projects or internal initiatives |
| 60-75% | Healthy | Balance maintained for business development |
| 75-85% | Optimal | Target range for most consulting firms |
| Above 85% | Over-utilized | Risk of burnout, consider hiring or rescheduling |
Track non-billable time categories separately: business development, training, internal projects, and administrative. Understanding bench composition helps convert non-billable time into productive activities.
Project Profitability Tracking
Real-time profitability dashboards compare revenue against labor costs and expenses for every active project. Early warning indicators flag projects trending toward budget overrun, enabling corrective action before margins erode.
| Metric | Calculation | Target |
|---|---|---|
| Gross margin | (Revenue - Direct costs) / Revenue | Above 50% |
| Budget burn rate | Actual hours / Budgeted hours | Below 100% |
| Revenue per consultant | Total revenue / FTE count | $150K-250K annually |
| Realization rate | Billed hours / Worked hours | Above 85% |
| Collection period | Average days to payment | Below 45 days |
Configure automated alerts when project profitability drops below threshold. The project manager receives a notification when budget consumption exceeds 80% or margin falls below the firm's target.
Proposals and Knowledge Management
Streamline the sales-to-delivery handoff by converting won proposals directly into pre-configured projects with tasks, budgets, and team assignments.
- Create proposal templates with standard scope, deliverables, and pricing for common engagement types
- Won proposals auto-generate projects with pre-defined task structures and milestones
- Internal knowledge bases store methodology documents, templates, and best practices
- New team members reference standardized delivery frameworks for consistent quality
- Post-project retrospectives feed lessons learned back into the knowledge base
Build a library of 5-10 project templates covering your most common engagement types. Templates should include standard task lists, typical timelines, and resource profiles. This reduces project setup time from hours to minutes.
