Odoo ERP for Professional Services: one system for the whole operation
Brainvire configures Odoo the way a firm actually runs: an opportunity that opens a project when the quote is accepted, hours that become invoice lines, retainers that draw down in the system, and profitability you can read while the job runs.
CRM, Project, Timesheets, Planning, Sales, Subscriptions and Accounting on one database, so the hour worked, the hour sold and the hour invoiced are one record.
Consultancies, agencies, IT and engineering firms and staffing businesses that sell people’s time against contracts.
Small implementations 8 to 12 weeks. Mid-market 12 to 24 weeks. Multi-entity firms 6 to 12 months. Brainvire’s estimates, not Odoo’s.
An Odoo functional consultant, a resourcing lead, an integration engineer, a data lead and a solution architect.
/ Before you change anything
Does your firm run on any of this?
Patterns we see where pipeline, schedule and ledger are separate documents.
You sell work you cannot staff
The proposal goes out before anyone checks who is free, so the win becomes a scramble.
Nobody is sure what is left on the retainer
Prepaid hours sit in a workbook that is accurate until somebody forgets. The argument arrives at renewal.
Work leaves the building unbilled
Expenses, subcontractor hours and out-of-scope requests get absorbed, because nothing recorded them against the job.
Partner numbers are assembled by hand
Each office keeps its own view, and the firm-wide picture is an export that is already a month old.

/ The work itself
What does Brainvire actually configure in Odoo for a services firm?
Odoo ships a working suite. The value is in the configuration. Feature detail lives on Odoo Project and Timesheets, the ledger on Odoo Accounting and the people records on HR and Payroll.
| Odoo default | What Brainvire changes | Why it matters |
|---|---|---|
| Opportunities and delivery live apart | CRM stages mapped to your pursuit process, with the project and its analytic account opened when the quote is accepted | Delivery starts from the scope that was sold, as built for AMASCO |
| One service product, one way of billing | A service product per way you sell: Prepaid/Fixed Price for fixed fees, Based on Timesheets for time and materials, milestone lines for staged fees | How a job was sold decides how it bills |
| Retainers kept outside the system | Prepaid hours sold as a service product priced in Hours on the Prepaid/Fixed Price policy, so timesheets draw the balance down; renewing retainers run in Subscriptions (Enterprise only) on a recurring plan with a renewal date, and deferred revenue models spread a fee across the periods it covers | What is left on a retainer is a number, and revenue lands in the right period |
| No analytic structure | Analytic accounts per client, engagement and practice, with cost rates on the employee record | Margin is answerable at the level you manage the firm |
| Profitability reviewed after the invoice | The profitability report on every billable project, so expected, to invoice and invoiced sit beside cost | A job going wrong surfaces while it can still be fixed |
| Shifts assigned from memory | Planning (Enterprise only) roles defined against the services you sell, shifts dedicated to projects, and Auto Plan filling an open shift | Resourcing uses the same records the work is delivered against |
| Costs claimed late and absorbed | Expenses linked to the project with re-billable costs flagged, and subcontractor invoices digitized into draft bills against that project | Recoverable spend reaches the invoice, not the write-off |
Feature names and behavior follow the Odoo 18 documentation. Planning, Subscriptions, Studio and Accounting are Odoo Enterprise applications and are not in Odoo Community.
/ AI where it touches the engagement
Where does AI earn its place in a services firm?
Four places automation pays for itself. The rest comes from configuration.
Client documents turned into records
For a US lighting manufacturer we built an agentic workflow that finds the purchase order among ticket attachments, reads it across PDF, Excel and text, and creates a validated draft order.
Subcontractor invoices read, not typed
Odoo document digitization turns associate and subcontractor invoices into draft bills with vendor, dates, taxes and lines populated, then routes them for approval against the project.
Conversations that stay with the work
For AmiViz, a cyber-security distributor, we built a chat module across web portal and mobile app, using AI and ML to engage users across departments.
Open shifts filled by role and availability
Roles, resources and the services they deliver are configured together in Odoo Planning, so Auto Plan proposes who covers an open shift.
What has to connect to a services firm’s ERP?
Odoo does not replace every system a firm runs. It has to agree with them.E-commerce
Firms that productize sell fixed-scope packages, prepaid blocks of work and training seats online. Whether the storefront is Shopify, WooCommerce or Odoo’s own web shop, the order should land as a subscription or a project.
and moreERP Systems
Leaving QuickBooks, Sage or an older ERP need not lose history. We map accounts, clients and open engagements record by record, then reconcile before cut-over, as we did for Skyetel across eight entities.
and moreEDI & Marketplace
Large clients pay through their own procurement portals and want their own invoice format. Odoo’s electronic invoicing covers the common structured formats.
and moreShipping Gateways
Services firms still ship: hardware for an installed project, printed deliverables, sample kits. Rates and labels belong on the delivery order.
and moreTaxation
Bill across states or countries and the treatment follows the client and where the work was performed. A tax engine wired to Odoo applies it at invoice time.
and morePayment Gateways
Retainers collect on a schedule and project invoices settle on terms, both against one receivable. A gateway on the subscription means the renewal charges itself.
and moreOther Integrations
Single sign-on, e-signature, BI dashboards and payroll all touch the operation. Each gets a defined interface, so a utilization figure traces back to a timesheet line.
and more/ Delivery
How does an Odoo rollout run in a services firm?
Small implementations 8 to 12 weeks, mid-market 12 to 24 weeks, multi-entity firms 6 to 12 months. A named owner and a working demo at each stage.
Discovery
We walk one pursuit end to end, from first conversation to cash, and list every system holding a client, a contract or an hour.
Design
Service catalog and invoicing policies, analytic structure, planning roles and the integration map are agreed in writing first.
Build and data
Configuration, integrations and any Studio work, then clients, contracts, open projects, unbilled time and balances into a test database.
Pilot and go-live
One office runs a full cycle first, proven with a real invoice run. The rest follow on a period boundary, with hypercare through the first close.
/ Scope
What makes a services scope bigger or smaller?
A typical engagement covers CRM, Project, Timesheets, Sales and Accounting for one entity and one way of selling work.
How many people record time
Every group that books hours brings its own approval path and its own billable week.
How the work is sold
Time and materials, fixed fee, milestones, prepaid hours and retainers are five products with five invoicing behaviors.
Companies, countries, currencies
Each legal entity adds a fiscal localization, a statutory report and intercompany rules for people lent across borders.
What the firm keeps
A CRM, HR system or practice tool you will not give up is an integration and a reconciliation, scoped as its own work.
/ Odoo, on the record
Where have we done this for services firms before?
Each card is one client, on the record.
Abu Dhabi Recruitment Group
A staffing business established in 1993, placing people into oil and gas, real estate, transport and finance roles. Project records, timesheets and leave lived in Excel. Brainvire built a customized Odoo solution across recruitment, projects, contracts, leave, payroll and invoicing.

AmiViz
A Middle East cyber-security enterprise associated with the Spectrami Group, a value-added distributor of cyber-security services. Brainvire used Odoo roles for reseller-specific access, rebate tracking, a read-only vendor portal, subscription renewals and timesheet-based services.

Skyetel
Skyetel delivers cloud VoIP to other businesses: calls, messaging, faxing, SMS and virtual numbers on one portal. It wanted stronger accounting than QuickBooks offered, so Brainvire built the multi-company architecture, migrated the data across sandbox and live, and closed with reconciliation and user testing.

/ Comparison
Odoo, or a practice tool plus separate accounting?
Plenty of firms run a specialist practice tool well. The question is what the join between it and the ledger costs when a contract type changes.
| Criterion | Practice tool plus accounting | Odoo |
|---|---|---|
| The billable hour | Recorded in the practice tool, then exported to the ledger | Recorded once; the invoice line reads it |
| Retainer balances | Maintained in one system, invoiced from another | Prepaid hours draw down on the order that raised the invoice |
| Job profitability | Revenue in one system, cost in another, joined in a report | Revenue and cost on one analytic account |
| Adding an entity | Configured again in every system that holds money | A company record with its own localization |
| Cost of a change | Regression-tested across every interface | Configuration in one place, custom code only where needed |
Keep the specialist tool if it does something your firm competes on. Choose Odoo if the integration work exists only to keep two systems agreeing about an hour. See Odoo ERP migration, Odoo 18 Enterprise, or the same approach in wholesale distribution.
/ Questions services firms ask
Odoo for professional services FAQs.
Is Odoo a good fit for a professional services firm?
Yes, when the firm sells people’s time against contracts. Odoo puts CRM, Project, Timesheets, Planning, Sales, Subscriptions and Accounting on one database, so the hour worked, the hour sold and the hour invoiced are the same record, rather than three numbers that have to agree.
How does Odoo handle a retainer?
Through Sales, not a separate retainer module. Prepaid hours are a service product with the invoicing policy set to Prepaid/Fixed Price and the unit of measure set to Hours, invoiced up front while timesheets draw the balance down. Renewing retainers run in Subscriptions, which is Enterprise only.
How does Odoo work out what a job earned?
Every billable project carries an analytic account, and the profitability report on the project dashboard reads every record linked to it. Revenue and cost appear in three columns: expected, to invoice or to bill, and invoiced or billed. A timesheet appears on both sides of that report.
Can one Odoo database run several practices, offices or legal entities?
Yes. Each legal entity is its own company record with its own fiscal localization, and shared people or costs move through intercompany rules. Practices inside one entity are better handled as analytic accounts, because a practice rarely files its own accounts.
How do subcontractors and associates get handled?
As vendors, with a purchase side and a delivery side. Their hours arrive as vendor bills against the project, so cost sits on the same analytic account as revenue. Where the contract allows, that cost reaches the client invoice instead of the write-off.
Does Odoo replace our CRM as well?
It can, and on this kind of build it usually should. Keeping the pipeline in Odoo CRM is what lets an accepted quote open the project and its analytic account. A CRM you will not give up becomes an integration, and a permanent mapping cost.
What do clients see, and how?
Whatever you invite them to see. Portal access is granted per contact, so a client signs in to read their own projects, documents, quotations and invoices rather than emailing for status. Signed proposals and change orders sit against the work they govern, so scope is not an email thread.
What happens to work in progress at cut-over?
Open jobs move as open jobs. We load clients, contracts, open projects, unbilled time and opening balances into a test database, reconcile the unbilled position against the old system, then agree a cut-over date. Closed history usually stays readable where it is.
