Billable-hour math for Portuguese invoices

What this calculation answers

A Portugal billable-hours calculation answers how much approved client work is worth before tax, then what the client pays after the applicable VAT treatment. Portugal uses the euro, so billable-hour amounts are normally calculated and invoiced in EUR unless the parties agree otherwise. Start with approved hours, agreed rates, and any non-billable exclusions before adding VAT.

For legal services, time spent is one fee factor under Portuguese bar rules, alongside importance, difficulty, urgency, creativity, result, responsibility assumed, and professional usages. Private lawyer billing is not tied to a national billing increment. The invoice still needs a clear service account when there is no prior written fee agreement, so your calculation should show the work category, hours, rate, and net fee.

Apply rates before VAT

The core formula is approved billable hours multiplied by the agreed hourly rate. Add each rate category to get the net fee before VAT. For Portuguese VAT, the taxable amount for services is the value received for the service excluding VAT, so VAT comes after the hour-and-rate calculation, not before it.

For example, a Portuguese client matter includes 24 approved strategy hours at €160 per hour and 18 approved drafting hours at €95 per hour. Strategy fees are €3,840, drafting fees are €1,710, and the net fee is €5,550. If mainland Portugal's 23% standard VAT applies, VAT is €1,276.50, making the invoice total €6,826.50.

Choose the billing detail carefully

Portugal does not prescribe a national 6-minute, 15-minute, or other billing increment for private lawyer invoices. The increment is a professional or contractual choice, so decide it before time is recorded. A 10-minute call, a 25-minute review, and a 50-minute drafting session can produce different totals depending on whether the agreement uses exact time, tenths of an hour, or quarter-hour rounding.

Do not treat every fee as purely result-based. A pure quota litis agreement, where the lawyer's fee depends exclusively on the result and is paid as part of the client's recovery, is prohibited. A pre-agreed fee or success uplift can be used alongside other fee criteria, but the billable-hours calculation still needs to support the net fee and the service account.

Move from invoice math to workflow

A one-off calculation is enough when you have a short matter, a single rate, approved hours, and a known VAT treatment. It is also enough for checking whether a draft invoice matches the engagement letter. Once multiple people, billing rates, write-downs, tax treatments, or payment deadlines enter the matter, spreadsheet math starts losing its audit trail.

For ongoing Portuguese client work, use a managed workflow that captures time where work happens, marks billable and non-billable entries, keeps project metadata attached, and hands clean totals to invoicing. Everhour integrates with major project management and accounting tools, embeds tracking controls in supported workflows, and syncs project and task metadata so billing review starts from recorded work rather than reconstructed notes.

Frequently Asked Questions

Should Portuguese billable hours be calculated before or after VAT?

Calculate billable hours before VAT. For Portuguese VAT, the taxable amount for services is the value received for the service excluding VAT, so the net fee comes first. Multiply approved hours by the agreed rate, add rate categories, then apply the relevant VAT rate if the service is taxable.

What VAT rate applies to legal services in Portugal?

Legal services generally use the standard VAT rate unless a specific reduced-rate or exemption rule applies. The standard rate is 23% in mainland Portugal, 22% in Madeira, and 16% in the Azores. Some services by lawyers, legal consultants, or solicitors qualify for the 6% mainland reduced rate when supplied in listed legal-aid or labor-proceeding situations.

Is there a required billing increment in Portugal?

No national statutory increment applies to private lawyer invoices in Portugal. Portuguese bar rules recognize time spent as one fee factor but do not require 6-minute, 15-minute, or hourly increments. The billing increment should come from the written fee agreement, firm policy, or client instruction.

What payment term should a Portuguese business invoice use?

For business-to-business commercial transactions, late-payment interest normally starts 30 days after invoice receipt if no due date is agreed. Agreed payment terms generally may not exceed 60 days unless expressly agreed and not abusive to the creditor. Public-entity debtors generally follow the 30-day rule, with limited extensions never beyond 60 days.

What happens when a Portuguese commercial invoice is paid late?

When late-payment interest becomes due in a commercial transaction covered by Decree-Law 62/2013, the creditor is entitled to at least €40 for debt-collection costs. For the first half of 2026, the supplementary late-payment interest rate for covered commercial transactions is 10.15%.

How does Everhour connect Portuguese billing work to project tools?

Everhour integrates with tools such as Asana, ClickUp, GitHub, Jira, Monday, Notion, Trello, QuickBooks, and Xero. Tracking controls can appear inside supported workflows, while project and task metadata sync into Everhour so billable time stays tied to the work source.
