How should a Portuguese firm bill projects from Odoo?
A Portuguese firm can plan projects, record timesheets and set billing by milestone, fixed fee or hours in Odoo Projects, but the invoice itself must come from software whose approval status for your exact Odoo setup is confirmed in writing, or from a separate approved program. I design the billing rules and that boundary with your accountant, check edition features, and work remotely as an independent consultant.

Portuguese service firms often sell abroad: software teams working for clients in other EU countries, engineering offices designing for foreign developers, equipment installers commissioning plants outside Portugal. The billing rule in the contract may be milestones, hours or a fixed fee, while the invoice must still meet Portuguese document rules.
I design Odoo Projects so the contract, the hours and the billing trigger line up, and I settle early which program issues the final invoice. Sessions run remotely with project leads and finance, the engagement runs in English, and Portuguese client documents are drafted by your own staff.
Each item links project delivery to billing, with the Portuguese invoice rules kept in view.
Fixed-fee phases, monthly hours and support retainers each become a service product with its own invoicing policy and a project template, so the sale already knows how it will be billed.
Before any billing rule is built, your accountant reviews and the partner answers in writing whether project invoices leave from Odoo or from a separate approved Portuguese program.
Time entry and validation habits that suit developers, engineers and technicians, so hourly billing and margins use complete data and corrections happen before invoices exist.
Projects for clients in other EU countries and further afield, with contract currencies, client portal access and the invoice wording your accountant confirms for cross-border services.
Service visits and recurring maintenance agreements for installers of equipment and energy systems, built on Field Service and subscriptions where those apps belong to your licensed edition.
Analytic accounts per project combining billed revenue, valued hours and purchases, tested on several finished jobs before managers use the result for pricing, staffing and bidding decisions.
Contracts and document rules
Products, templates and hours
First invoicing cycle checked
Odoo Projects decides when and how much to invoice; Odoo Accounting creates the invoice. In Portugal that second step carries a legal condition: invoices, credit notes and some related documents are normally expected to come from a program with approval from the tax authority, with registered series, a code on each document, a QR code and data for the SAF-T file. The status belongs to a specific product, version and setup.
Billing design therefore waits until the partner has put in writing what the edition, release and hosting you will run may issue, and your accountant has read that reply. The project design then follows one of two routes:
Custom modules that change invoice behavior can affect the position, so I ask before anyone builds them. The ledger detail is on Odoo Accounting in Portugal, and the general billing models on my Odoo Projects page.
Portugal has many technology and engineering firms delivering work to clients elsewhere in Europe and beyond. Their contracts are often agreed in English, priced in euro or another currency, and billed monthly on hours or per delivery phase. Clients may want visibility of progress without access to internal discussions.
In Odoo I would set this up as follows:
Services sold to businesses in other EU countries, or outside the EU, raise VAT place-of-supply questions and specific invoice wording. Your accountant confirms the treatment, and I check that the fiscal positions in Odoo, or in the separate invoicing program, apply it. Some firms also need hours for funded innovation projects; the evidence standard comes from your advisor, while Odoo provides the data. See also IT services ERP.
Portuguese firms that install solar panels, heat pumps, industrial lines or building systems carry two kinds of work on the same customer. First a job with a start and an end: site survey, equipment ordered, crews sent, system switched on and handed over. Then an open-ended relationship: inspections, repairs and a service agreement that rolls over. Odoo keeps both attached to the same equipment if the setup is planned that way.
What I would put through the test database:
One Portuguese detail is easy to forget: equipment driven from your warehouse to a roof or a plant is a road movement, so the transport document rules cover it just as they cover a sale. I connect this to the dispatch decision made for inventory and check it with your accountant. Field Service and recurring billing may be Enterprise apps in your release, and the partner states that on paper. Related reading: ERP for field service.
For architects, engineering offices and consultancies in Portugal, profitability depends on hours: how many a phase took, how many were billable and what they cost. Odoo values validated timesheets at a cost rate and compares them with revenue and purchases on each project's analytic account. That view is only as good as the timesheet habit behind it.
Elements I design with the team:
Before relying on the profitability report, I run it on a few finished projects and compare it with what finance knows about them. Differences are explained and the rules adjusted. Project timesheets serve billing and cost; any labor law requirement to record working time is separate, and your labor advisor confirms whether one system can serve both. Broader project costing is covered on ERP for project costing.
Odoo Projects earns its place when work is sold through sales orders and the firm wants hours, purchases and billing to meet in one database. Several Portuguese situations argue against it, and I would rather raise them at the start than after a partner has quoted.
Signs that another setup may serve you better:
Then the useful work is a requirement list and a fair comparison, run through ERP evaluation, or a link between the delivery tool and your Portuguese invoicing program. I hold no Odoo partnership, sell no licenses and accept no referral fees. Sessions are remote and fit easily into Lisbon or Porto office hours; on-site days only by arrangement. The country overview is on my Portuguese ERP consultant page.

Share your business requirements with me and I will help you understand the right process, architecture and platform before implementation.
Projects decides what to bill; invoices are issued by Odoo Accounting or another program. Whether Odoo may issue them depends on the written approval status of your exact edition, version and hosting, reviewed by your accountant. If unclear, a separate approved program issues the invoice from Odoo's billing data.
Yes. Odoo's customer portal can show selected tasks and timesheets to clients, so they can check hours before the monthly invoice. I set access so internal notes stay private and test it with a real client account before go-live. Clients then approve rather than dispute.
Probably, since Field Service has historically shipped with Enterprise, and recurring billing and planning may too. Odoo does move apps between tiers from release to release, so your technicians' requirements go to the partner as a checklist, and their written reply for your edition and hosting is kept on file.
Materials moved by road from your warehouse to a customer site generally need a transport document under Portuguese rules, with exceptions your accountant can explain. I align project material flows with the inventory dispatch design so every movement has the right document.
Every business is different. Share where you are today and what you want to fix, and I’ll tell you honestly whether and how I can help.
