An email invoice for Spain should give the buyer a complete, reviewable document without extra back-and-forth. The attached invoice needs the supplier and customer details, a clear invoice number, the correct dates, line items, IVA treatment, total due, and payment instructions. The email itself can stay short because the attachment carries the legal and accounting detail.
Royal Decree 1619/2012 regulates Spanish full invoices. A full invoice must include an invoice number and, where applicable, a series, with sequential numbering within each series. Separate series are required for rectifying invoices and certain other cases. For B2B work, the invoice generally must be issued before the 16th day of the month after the VAT accrual month.
A Spanish full invoice must show the issue date and the date of the documented supply or advance payment when that date differs from the issue date. It must identify the supplier and customer 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.
Each line should describe the goods or services with enough detail to determine the VAT taxable base. Include the unit price before tax, discounts not already included in that price, the IVA rate, and the VAT amount charged. Spain's indirect tax is IVA, with a 21% general rate, 10% reduced rate, and 4% super-reduced rate. The Canary Islands, Ceuta, and Melilla sit outside the harmonized VAT area.
The invoice can be issued in any language and amounts can be expressed in any currency, but any VAT charged must be expressed in euros. A buyer may still request a Spanish version for internal review, and the tax administration can require translation into Spanish or another official language in Spain for audit purposes. A clean PDF attachment with a short payment email usually prevents confusion.
Spain's mandatory B2B e-invoicing system is being phased in under Royal Decree 238/2026. It applies when the recipient is a business or professional established or resident in Spain, except most simplified invoices. Effective dates are deferred until 12 months after the implementing ministerial order for businesses above €8 million annual turnover and 24 months for other businesses and professionals.
A free invoice tool is enough for a one-off Spain invoice when you already know the buyer details, IVA treatment, payment term, and line items. It is also enough when the invoice does not need to connect to tracked project work, time approvals, or later reporting. Keep the sent PDF and email record with the project file.
A managed workflow matters when billable hours, expenses, and project records feed the invoice. Everhour can keep the work behind the invoice visible through customizable reports with columns, grouping, filters, exports, and invoice-related data. That reporting trail helps teams review what was billed, what remains uninvoiced, and which projects need follow-up before the next invoice email goes out.

A PDF invoice can work for ordinary email delivery when the invoice contains the required Spanish full-invoice fields. For B2B recipients established or resident in Spain, the phased B2B e-invoicing mandate under Royal Decree 238/2026 adds a separate compliance layer once the effective date applies to the supplier category.
A Spain invoice should use the IVA rate that applies to the goods or services sold. Spain's VAT law sets a 21% general rate, a 10% reduced rate, and a 4% super-reduced rate. The invoice should separately show the VAT rate and VAT amount charged, and special VAT wording applies for exemptions, reverse charge, cash accounting, or other special regimes.
A Spain invoice may be issued in any language. The tax administration can require translation into Spanish or another official language in Spain for audit purposes. For smoother buyer processing, use clear commercial terms, label IVA consistently, and make supplier NIF, customer details, line descriptions, dates, taxable base, and totals easy to find.
Any VAT charged on a Spain invoice must be expressed in euros, even when the invoice amounts are shown in another currency. The invoice should make the taxable base, IVA rate, VAT amount, and total payable clear enough for the buyer to post the invoice without asking for a revised document.
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. Agreed payment terms cannot exceed 60 calendar days. The invoice email should repeat the due date stated on the invoice.
Everhour Reporting lets teams build reports with 45+ columns, metadata filters, grouping, date ranges, and exports. A billing manager can review billable time, non-billable time, invoice status, project, client, member, and cost data before sending Spain invoice emails or following up on unpaid work.
Everhour Billing & Invoicing converts tracked billable time and expenses into client invoices. Users can select uninvoiced time and expenses, preview the breakdown, group invoice lines by project, task, person, or date, and keep invoiced time from appearing again in future invoices.
Use a one-off invoice for simple sends. For recurring client work, Everhour connects reporting, invoice status, and billable project data so Spain billing stays traceable.
