Legal billing math for Portuguese matters

What this calculation answers

An attorney billing total in Portugal answers a concrete invoice question: how much the client owes for approved legal work before VAT, how much VAT applies, and what the final invoice amount is in EUR. The starting point is the agreed fee structure. That can be an hourly rate, a fixed fee, or an itemized account of services when there is no prior written fee agreement.

Portuguese bar rules treat time spent as one fee factor, alongside importance, difficulty, urgency, creativity, result, responsibility assumed, and professional usages. That means the calculation is not only a timer total. For an hourly matter, multiply approved hours by the agreed rate. For a fixed-fee matter, use hours to support internal review, profitability, or client explanation rather than to create the fee itself.

Apply rates before VAT

For Portuguese VAT, the taxable amount for services is the value received for the service excluding VAT. In a standard hourly legal invoice, calculate net legal fees first, then add VAT where required. Legal services generally use the standard VAT rate: 23% on mainland Portugal, 22% in Madeira, and 16% in the Azores, unless a specific reduced-rate or exemption rule applies.

For example, a mainland matter includes 14 partner hours at €280 per hour and 9 associate hours at €150 per hour. The partner subtotal is €3,920 and the associate subtotal is €1,350, so net legal fees are €5,270. At 23% VAT, VAT is €1,212.10. The client-facing invoice total is €6,482.10 before any reimbursable expenses, discounts, or write-downs.

Choose increments and fee basis

Portugal does not prescribe a national 6-minute, 15-minute, or other billing increment for private lawyer invoices. The increment comes from the engagement letter, firm policy, or client billing rules. If the agreement says time is billed in tenths of an hour, apply that consistently before multiplying by the rate. If the agreement uses actual time or fixed fees, do not force a different increment into the invoice.

One common mistake is treating captured time, billable time, and invoiced value as the same number. Captured time records work performed. Billable time is the portion allowed under the client agreement. Invoiced value is the amount actually charged after rates, fixed-fee limits, discounts, write-downs, and VAT. Keep those layers separate, especially because a pure quota litis agreement, where the fee depends exclusively on the result and is paid from the client recovery, is prohibited.

Move from totals to invoices

A one-off calculation is enough when you need to price a small hourly matter, check VAT on a draft invoice, or compare an agreed fixed fee against time spent. It is also enough for a quick client estimate when payment terms, rates, and taxable treatment are already clear. For business-to-business commercial transactions in Portugal, payment timing still matters because the default late-payment trigger is tied to invoice receipt.

Use a managed workflow when multiple people enter time, some tasks are non-billable, invoices need client-specific terms, or payment follow-up matters. Everhour Billing & Invoicing converts tracked billable time and expenses into invoices, calculates invoice amounts from rates while excluding non-billable tasks, and exports invoices to QuickBooks Online, Xero, or FreshBooks with status synced back to Everhour.

Frequently Asked Questions

Does Portuguese attorney billing use one required time increment?

No. Portugal's bar rules recognize time spent as one factor in lawyer fee setting, but they do not prescribe a national 6-minute, 15-minute, or other billing increment for private lawyer invoices. Use the increment in the written fee agreement, client billing guidelines, or firm policy. If none is agreed, keep the itemized service account clear and consistent.

When is VAT added to a Portuguese legal invoice?

VAT is added after the net legal fee is calculated. For Portuguese VAT, the taxable base for services is the value received for the service excluding VAT. Legal services generally use the standard rate: 23% on mainland Portugal, 22% in Madeira, and 16% in the Azores, unless a specific reduced-rate or exemption rule applies.

Can a Portuguese lawyer charge only a percentage of the result?

A pure quota litis agreement is prohibited in Portugal. That means the lawyer's fee cannot depend exclusively on the result and be paid as part of the client recovery. A pre-agreed fee or success uplift can exist alongside other fee criteria, but the fee structure must not be exclusively result-based in that prohibited form.

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. For public entities, the payment period generally follows 30 days and cannot exceed 60 days under the specified conditions.

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, without prejudice to proving higher reasonable costs. The supplementary late-payment interest rate for the first half of 2026 is 10.15%.
