Spanish billable-hour math and invoice checks

What this calculation answers

The calculation answers one practical question: how much approved client work should appear on a Spanish invoice before taxes, withholding, expenses, discounts, or collections. Start with hours that the client agreement treats as billable, not every hour worked. Internal meetings, training, rework outside scope, and admin time belong outside the billable total unless the contract says otherwise.

For Spain, keep the output in EUR because billable-hour rates, invoices, VAT, withholding, and statutory late-payment amounts are normally expressed in euros. Spanish attorney fees are freely agreed between the client and the legal professional, and the invoice must detail fee concepts and expense items, so the calculation should preserve the categories behind the final number.

Build the invoice subtotal

Use this formula: approved billable hours multiplied by the agreed hourly rate, summed across each role, person, or work category. If a matter has more than one rate, calculate each line separately before adding the subtotal. Do not average rates first unless the client agreement uses one blended rate for the whole engagement.

For example, a Spanish client advisory file includes 28 approved legal review hours at €150 per hour and 19 approved drafting hours at €110 per hour. Legal review equals €4,200, drafting equals €2,090, and the invoice subtotal is €6,290 before VAT, withholding, expenses, discounts, or late-payment charges. The line detail matters because Spanish professional invoices must itemize fee concepts and expenses.

Check Spain-specific billing rules

Spain's general VAT rate is 21%, which is the default rate for taxable professional services unless a specific reduced rate, exemption, or non-taxable place-of-supply rule applies. VAT applies to paid supplies of services by businesses or professionals in Spanish VAT territory, covering mainland Spain and the Balearic Islands, but excluding the Canary Islands, Ceuta, and Melilla.

On the €6,290 subtotal above, 21% VAT adds €1,320.90, producing a €7,610.90 invoice total when Spanish VAT applies. Payment timing is separate from the hours math: for commercial operations, the default term is 30 calendar days after services are provided if no date is set, and agreed terms cannot exceed 60 calendar days. Suppliers must deliver the invoice within 15 calendar days after service provision.

Calculator versus managed workflow

A one-off calculation is enough when the time record is clean, the rate table is simple, and you only need a subtotal for one invoice. It works for a small advisory file with one client, two rates, and no disputed time. Before sending, confirm the VAT place-of-supply treatment, any Spanish withholding, the payment term, and whether each invoice line matches the client agreement.

A managed workflow is better when several people log time, some tasks are non-billable, rates vary by project or person, and invoices need approval before accounting. Everhour supports billable and non-billable time through project billing status, task-level non-billable controls, custom task rates, member-rate exceptions, and admin reports showing billable time, non-billable time, billable amount, and cost.

Frequently Asked Questions

Which hours belong in a Spanish client invoice?

Include hours that were worked, approved, and billable under the client agreement. Exclude internal admin, training, write-offs, and non-billable client support unless the contract or engagement letter allows them. For Spanish attorney-fee work, keep the line categories clear because the invoice must detail the different fee concepts and expense items.

Is Spanish VAT added before or after multiplying hours by rates?

Multiply approved billable hours by agreed hourly rates first, then apply VAT to the taxable invoice base when Spanish VAT applies. Spain's general VAT rate is 21% for taxable professional services unless a reduced rate, exemption, or place-of-supply rule changes the treatment. Do not add VAT to hours; add it to the taxable EUR amount.

Do Spanish billing increments have a statutory formula?

Spanish attorney-fee rules leave the billing method and increments to the client-lawyer agreement, so there is no countrywide statutory rounding formula for every invoice. Use the increment in the engagement terms or firm policy, such as 0.1 hour or 15 minutes, and apply it consistently before multiplying by the agreed rate.

What payment term should a Spanish commercial invoice use?

For commercial operations between businesses or with the public sector, Spain sets a 30-calendar-day default payment term when the contract does not set a payment date. The parties can agree on a term, but it cannot exceed 60 calendar days. The supplier must deliver the invoice or payment request within 15 calendar days after the services are provided.

What happens when a Spanish business invoice is paid late?

When a debtor falls into late payment under Spain's commercial late-payment law, the creditor is entitled to statutory late-payment interest unless a contractual rate applies. The statutory rate is the European Central Bank main refinancing rate before the semester plus eight percentage points, fixed for the following six months, plus a fixed €40 recovery-cost charge.

How does Everhour separate billable and non-billable Spanish client work?

Everhour supports billable and non-billable time through project billing status, task-level non-billable controls, custom task rates, and member-rate exceptions. Admin reports can show billable time, non-billable time, billable amount, and cost, so Spanish invoice preparation starts from approved categorized time instead of a flat timesheet total.

How does Everhour help prepare invoice handoff after the hours are approved?

Everhour Billing & Invoicing turns tracked billable time and expenses into invoices, calculates amounts from rates while excluding non-billable work, and can group line items by project, task, person, or date. Invoices can be exported to QuickBooks Online, Xero, or FreshBooks as drafts.
