Retainers, hourly rates and fixed fees: how US firms sell services

Most American service businesses I meet sell in more than one way at once. A digital agency runs monthly retainers alongside one-off campaign builds. An IT consultancy bills implementation work hourly but sells support as a block of prepaid hours. An engineering or architecture practice quotes a fixed fee per phase and bills extra services by the hour once the scope moves.

In Odoo each of those becomes a separate service product, because the product decides whether invoicing follows ordered quantity, delivered timesheet hours or reached milestones. A single sales order can carry several of them, which is how a fixed-fee build and an hourly change request live side by side without anyone splitting invoices by hand.

Two US habits need deliberate design:

• Role-based rates. Clients often expect a senior consultant and an analyst to bill at different rates. Odoo can price this through separate products per role or rate rules tied to employees on a project, depending on your version, so I test which one your invoices can live with.
• Not-to-exceed caps. Odoo does not generally stop people logging hours at a contract ceiling. I build a budget view and an alert routine so a project manager raises a change order before the cap, not after.

The Odoo Projects overview explains the underlying billing types; this page is about applying them to how American firms write contracts.

Timesheets for employees, exempt staff and contractors

In the US, the hours that drive client billing and the hours that drive payroll are often different records. Salaried exempt staff may never clock in for pay purposes, yet every billable hour they work still needs to reach a project. Hourly nonexempt employees have overtime rules that belong in your payroll provider, not in project billing. I keep the two apart so a timesheet policy for invoicing does not become an accidental payroll record.

Contractors are the other common gap. Many US firms rely on independent contractors for design, development or specialist work. There are two workable patterns in Odoo:

• Contractors get a user and log timesheets directly, which gives task-level detail but adds licensing cost per person.
• Contractors invoice you, and the vendor bill lines carry hours and post to the project's analytic account, with billable time re-invoiced to the client where the contract allows.

Whichever route you choose, the weekly rhythm matters more than the tool. I agree a cut-off that suits your spread of time zones, a manager review step, and a report of missing hours that runs before the invoice batch. Timesheet validation and grid entry sit in Enterprise in most setups, so I check your edition before promising that workflow.

Sales tax on services, several LLCs and margin in dollars

Many states do not tax professional services at all, while others tax specific categories such as certain digital, data or repair services. Where that applies to you, each service product needs a classification your sales tax setup can act on, whether you rely on Odoo's own tax rules or a tax calculation connector such as Avalara, whose availability you should check for your edition and version. I configure what your tax advisor decides; I do not decide taxability.

Entity structure is the other American pattern. It is common to see an operating LLC per state or service line, plus a separate company that employs the staff. Project profitability then needs:

• Analytic plans for client, practice and entity, so a project can be read in more than one dimension.
• Intercompany labor recharges where people employed by one company deliver work sold by another, agreed with your accountant.
• Realistic hourly costs loaded with benefits and payroll taxes, so margin in dollars is not flattered.

The ledger side of this, including sales tax reporting and bank feeds, is covered on my Odoo Accounting page for the US. For project costing as a business problem rather than a product, see ERP for project costing.

Managed service providers, helpdesks and field technicians

A large group of American Odoo projects users are not classic project firms at all. Managed service providers, AV integrators, security installers and commercial HVAC or electrical contractors sell recurring support plus occasional install projects, and their hours are split between tickets, scheduled visits and project tasks.

Odoo can bring those together when the edition supports it:

• Helpdesk tickets that log time against a prepaid hours product or a support contract, so a client can see what remains.
• Field Service tasks with scheduling, on-site worksheets and customer sign-off that feed timesheets and materials into the invoice.
• Subscriptions for the monthly managed-service fee, kept separate from billable project work.

Helpdesk, Field Service and Subscriptions are generally Enterprise apps, and their exact features shift between versions, so I confirm what your edition actually includes before designing around them. Where technicians already live in a dedicated dispatch tool that works, I would rather integrate than replace it.

For the wider service picture, see ERP for field service and my page on IT services.

When you need construction project accounting instead

Some US firms that ask about Odoo projects are really general contractors or specialty subcontractors. Their billing runs on AIA-style pay applications against a schedule of values, with retainage withheld on each application, lien waivers exchanged with every payment, certified payroll on prevailing wage jobs, and WIP schedules that a surety or lender reviews. Odoo can hold the projects, purchases and timesheets, and milestone billing can approximate a simple progress claim, but pay applications, retainage tracking and over-and-under billing schedules are not native in most setups and would need add-ons or significant customization.

If that describes your business, I would assess construction-focused accounting alongside Odoo before you commit, and you can read how I approach that on my construction ERP page for the US.

For firms that sell expertise, Odoo is usually a strong fit. My role is independent: I map how you sell and deliver, write the billing and timesheet rules, and either guide the setup or review the implementer's work. You can see how this sits within my wider Odoo consulting in the US, my ERP consulting for American businesses and the US hub. Process work starts with process mapping.
