Professional ServicesBill More Hours. Spend Less on Admin.
Consultants, agencies, and law firms lose revenue not because they lack clients -but because billable hours slip through the cracks. We configure Odoo so time tracking flows directly into invoices, projects show real profitability, and nobody spends Friday afternoon chasing timesheets.

The Odoo Solution

Why Odoo for Professional Services
Professional services billing breaks at the same place every time: between the moment the consultant did the work and the moment the invoice reaches the client. In between sits a chain of timesheet entry, manager approval, rate matching, project-stage attribution and invoice generation. Each step is an opportunity to lose an hour or introduce an error. Odoo closes that chain inside one application. Project, Timesheets, Sale and Invoicing share a single data model with no integrations between systems.
The second bottleneck is project profitability. Most agencies discover a project is unprofitable only when they close the month in Excel. Odoo shows actual vs planned by hours, rate and margin at the moment the work happens, not 30 days later. The project manager sees on the dashboard that actual effort is already 80% of budget at 60% completion and acts immediately, before the client gets a surprise invoice.
The third layer is resource planning. Who do we staff on next week's project, who has free hours, who is overloaded? Resource Planning in Odoo shows team availability visually, by day, factoring in leave and locked allocations. It removes the classic agency pain: two seniors assigned to the same task while another project drowns understaffed.
On top, Odoo solves the admin wrap-around of professional services for free: contracts via Sign, expenses via Expenses, recurring invoicing via Subscriptions for retainer models, knowledge base via Knowledge for team handover. This is all built in. You do not buy a separate SaaS tool per function.
How we ship it
A standard project for a 10-50 person agency or consultancy takes 8-12 weeks. The phases are fixed, and so are the deliverables at the end of each one.
Discovery (1-2 weeks)
Interviews with CEO, project managers and CFO. We capture the current process: how clients are onboarded, how projects are sold, how time is tracked, how invoices go out. We document 5-10 typical scenarios and agree on the target model.
Setup and migration (2-3 weeks)
We configure project structures, stages, task types, role-based rates and expense categories. Import customers, open projects and the last quarter of timesheet history. Invoice templates, branding, tax setup.
UAT with key users (2-3 weeks)
Parallel run: the team continues in the old system and duplicates key operations into Odoo. We collect feedback, fix gaps, adjust configuration, and add custom fields and automations where they provide real leverage.
Go-live and stabilization (1-2 weeks)
Cutover at the start of a new period, usually month or quarter. The old system goes read-only. For the first two weeks we are on hand daily: helping the team push the first 10 invoices, resolving timesheet edge cases, calibrating reports to actual CFO questions.
Metrics we move
Not marketing claims. These are the ranges we see at clients in the first year after go-live.
Because timesheets are filled daily on mobile and flow automatically into invoices, instead of getting lost between Excel and Outlook.
Month-close drops from 7-10 days to 2-3 days. Hours are already attached to projects and stages, so the invoice is one click.
Margin per project is visible while the work is happening, not at quarter-close. Resourcing and scope decisions get made before the project burns.
What professional services directors ask
Will Odoo work for a 15-person agency? Is it overkill?+
No. For a 10-50 person team, Odoo Enterprise hits the right point: enough functionality for professional services (Project, Timesheets, Sale, Invoicing, Subscriptions) without enterprise-ERP complexity. A typical installation runs 80-120k USD in year one including licenses, implementation and customization. Alternatives like Harvest + Xero + Notion give 70% of the functionality but require integrations and lose data coherence. Odoo is one source of truth.
What about billing on time and materials vs fixed-fee vs retainer?+
All three models are supported natively. Time and materials: timesheets flow into invoices at role-based rates with discounts and taxes applied. Fixed-fee: milestone billing per project stage, optionally with overage rebilling. Retainer: recurring subscriptions via the Subscriptions module, with auto-generated monthly invoices and a client-facing hour consumption dashboard.
How does it integrate with Slack, Teams and Google Calendar?+
Calendar syncs via CalDAV natively. Slack and Teams plug in through the Discuss module with two-way channel mapping, plus notifications for new tasks, mentions and overdue timesheets. Email uses the built-in mail server plus an inbound gateway, so client emails create tickets automatically.
Can clients see their project and hours in real time?+
Yes. Customer Portal gives each client secure access to their projects, tasks, hours logged and invoices. Detail level is configurable per client: some see only a stage total, others see every timesheet line. This kills 80% of the 'what were you working on last Thursday' questions.
What about GDPR and contracts for EU clients?+
Odoo.sh hosting in the EU is GDPR compliant. The Sign module provides legally binding electronic signature (eIDAS-compatible). DPAs with Odoo SA are signed on request. For client and contractor contracts we use templates with auto-fill from CRM plus an audit log of changes. This covers baseline compliance for EU professional services.
How long does Rteam typically take to go live with Odoo for a professional services firm?+
For a professional services firm with standard requirements, such as project tracking, timesheets, invoicing, and a basic CRM, Rteam typically delivers a go-live in 6 to 10 weeks. That window covers a discovery workshop, configuration, data migration for active projects and contacts, user acceptance testing, and two rounds of staff training. Firms with complex multi-entity billing or custom approval workflows should plan for 12 to 16 weeks. We use a fixed-scope starter package to keep the first phase predictable, then layer in additional modules after your team is comfortable with core operations. Scope creep is the main driver of delays, so we document every requirement before development begins.
Can Rteam configure Odoo to automate invoice generation from approved timesheets?+
Yes. Odoo's invoicing engine can be set to pull approved timesheet lines automatically and generate a draft invoice on a schedule you define, weekly, bi-weekly, or at project milestone. Rteam configures the approval chain first, so only hours signed off by a project manager flow through. We also set up invoice templates per billing type, showing narrative descriptions rather than raw task names, which reduces client queries. Firms that move to this workflow typically cut invoice preparation time by 60 to 70 percent and shorten payment cycles because invoices go out faster and with fewer errors.
