Use this page to prepare invoices for customers in Spain, especially when billable hours, project fees, expenses, discounts, and IVA need to appear in a clean document. A Spanish full invoice is regulated mainly by Royal Decree 1619/2012, so the output needs more than a client name and total due.
The practical goal is a document a customer can approve, pay, and keep for accounting records. That means sequential invoice numbering, clear supplier and customer identification, dates, line items, tax bases, IVA rates, IVA amounts, payment terms, and any required wording for exemptions, reverse charge, cash accounting, or a special regime.
A Spanish full invoice must include an invoice number and, where applicable, a series. Numbering within each series must be sequential, with separate series required for rectifying invoices and certain other cases. The invoice also needs an issue date, plus the supply date or advance payment date when that date differs from the issue date.
Supplier and customer details matter. A full invoice must identify both parties by full name or business name and address, and it must include the supplier's NIF. The customer's NIF is required for domestic taxable operations and specified cross-border or reverse-charge cases. Line items need enough detail to determine the IVA taxable base, including unit price before tax and discounts not already included.
Spain's indirect tax is IVA. The VAT law sets a 21% general rate, a 10% reduced rate, and a 4% super-reduced rate. The invoice must separately show the IVA rate and IVA amount charged. Spain's VAT territory excludes the Canary Islands, Ceuta, and Melilla from the harmonized VAT area, so those locations require extra care.
Invoice amounts may appear in any currency, but any VAT charged must be expressed in euros. Invoices may be issued in any language, although the tax administration can require translation into Spanish or another official language in Spain during an audit. For B2B customers, invoices generally must be issued before the 16th day of the month after the VAT accrual month.
A one-off invoice tool works for a simple client, a single project, or a document you need to issue today. It gives you structure, totals, IVA fields, and payment terms without building a full billing process. For commercial transactions between businesses or with public administrations, the default payment period is 30 calendar days after receipt of goods or services if the contract does not set a date, and agreed payment terms cannot exceed 60 calendar days.
A managed workflow becomes necessary when tracked time, per-person rates, project overrides, expenses, approvals, and accounting exports need to stay consistent month after month. Everhour separates cost and billable rates, supports per-person defaults and per-project overrides, preserves dated rate history, and can price billable work by project, member, or task before the invoice is created.

Royal Decree 1619/2012 regulates Spanish full invoices. A compliant full invoice needs sequential numbering, issue and supply dates when different, supplier and customer identification, line-level taxable-base details, IVA rate, and separately stated IVA amount. Special wording applies when the transaction uses an exemption, reverse charge, cash accounting, customer self-billing, or another covered special regime.
The customer's NIF is required for domestic taxable operations and specified cross-border or reverse-charge cases. Supplier NIF belongs on a full invoice. Client records should separate full legal name, business address, NIF, tax treatment, and billing contact so the invoice does not mix payment routing details with tax identification.
Spanish invoice amounts may be expressed in any currency, but any VAT charged must be expressed in euros. A practical invoice should show the transaction currency, the euro VAT amount, the exchange-rate basis used for accounting, and the payment currency the customer must use.
Spain uses IVA with a 21% general rate, a 10% reduced rate, and a 4% super-reduced rate. The correct rate comes from the goods or services supplied and the transaction's tax treatment. A mixed invoice should separate lines by IVA rate so each taxable base and VAT amount stays clear.
Spain is phasing in mandatory B2B e-invoicing for recipients that are businesses or professionals established or resident in Spain, except most simplified invoices. Effective dates start 12 months after the implementing ministerial order for businesses above €8 million annual turnover and 24 months for other businesses and professionals.
Everhour separates internal cost rates from client-facing billable rates, with default per-person rates and per-project overrides. Rate changes can apply from a chosen date, so older reports keep their original calculations while new Spanish client invoices use the current project, member, or custom task rate.
Everhour can generate invoices from uninvoiced billable time and expenses, with amounts calculated from rates, tracked time, and billable expenses while non-billable work stays excluded. Invoice line items can be grouped by project, task, person, date, or other available breakdowns before export to QuickBooks Online, Xero, or FreshBooks.
Track approved work with dated billable rates, then turn clean project records into client invoices. Everhour keeps rates, billable time, and invoice preparation connected.
