Use this page when you need to prepare an invoice for a customer in Spain and want the right commercial details in place before sending it. A Spanish full invoice is regulated mainly by Royal Decree 1619/2012, so the document needs more than a logo, total, and bank details. Sequential numbering, supplier identification, customer identification, issue date, and line-level tax details all matter.
The practical goal is a finished invoice that a client can approve, pay, and keep for records. For business customers, the invoice generally must be issued before the 16th day of the month after the IVA accrual month. Payment terms also need attention: business transactions default to 30 calendar days if no date is set, and agreed terms cannot exceed 60 calendar days.
A full Spanish invoice needs an invoice number and, where applicable, a series. Numbering inside each series must be sequential, and rectifying invoices require separate series in specified cases. Add the issue date, plus the supply date or advance payment date when it differs from the issue date. Identify the supplier with full name or business name, address, and NIF.
Customer details depend on the transaction. Domestic taxable operations require the customer's NIF, and specified cross-border or reverse-charge cases require it as well. Each line should describe the goods or services, show the taxable base, unit price before tax, discounts not already included in that unit price, IVA rate, and IVA amount. Relevant exemption, reverse-charge, cash-accounting, self-billing, or special-regime wording belongs on the invoice when it applies.
Spain uses IVA, with a 21% general rate, a 10% reduced rate, and a 4% super-reduced rate. The invoice should place IVA either clearly at line level or in a summary that lets the taxable base, rate, and VAT amount be checked. The Canary Islands, Ceuta, and Melilla sit outside Spain's harmonized VAT territory, so those locations need separate review before you apply mainland IVA treatment.
Invoice amounts can be shown 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 a Spanish or other official-language translation for audit. Spain is also phasing in mandatory B2B e-invoicing under Royal Decree 238/2026 for recipients that are businesses or professionals established or resident in Spain, except most simplified invoices.
A one-off invoice app works for a simple client invoice when you already know the customer details, IVA treatment, payment term, and final amount. It is enough for occasional billing, corrected drafts, or a small batch of invoices that do not need approval history or time-based backup. Keep a copy of the source records behind the invoice, especially when billing services by day, person, project, or task.
A managed workflow becomes the better fit when billable time, expenses, rates, and invoice status need to stay connected. Everhour Reporting can organize logged work with customizable columns, filters, grouping, exports, and scheduled email delivery, so project billing data is easier to review before an invoice is issued. That reporting layer supports the decision trail behind client charges without turning the invoice itself into a timesheet.

Sequential numbering, the customer's NIF in required cases, the supply date when it differs from the issue date, and separate IVA amounts are common misses. Line items also need enough detail to determine the taxable base, including unit price before tax and discounts not already included in that price.
No. Spain's IVA system has a 21% general rate, a 10% reduced rate, and a 4% super-reduced rate. The correct rate depends on the goods or services and any applicable exemption, reverse charge, cash-accounting regime, or special regime. The invoice must show the VAT rate and VAT amount separately.
Yes. Invoice amounts may be expressed in any currency, but any VAT charged must be expressed in euros. That means a client-facing invoice can use another commercial currency, while the IVA amount still needs a euro figure for Spanish tax records.
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, so longer terms should not appear as the contractual due date.
Spain is phasing in mandatory B2B e-invoicing under Royal Decree 238/2026 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 Reporting lets teams review billable work with customizable columns, grouping, filters, date ranges, and exports before invoice amounts are finalized. Reports can include project, client, member, billable time, costs, profit, invoice status, and budget metrics, giving approvers a clearer billing record.
Everhour Billing & Invoicing can generate invoices from uninvoiced time and expenses, then mark included time as invoiced so it does not appear again in later invoices. That status helps prevent duplicate billing when multiple invoices cover the same client or project.
Use Everhour Reporting to review billable work, export the backup, and keep project billing data organized before invoices go out, giving each invoice a clearer operational record.
