Invoicing Software for Spain
Points to check before picking an invoicing tool for work in Spain. Each one cites the Tax Agency or the official gazette with its date, and Billed's features follow in Billed's words.
In Spain, the rules reach the invoicing software itself. The Tax Agency's (AEAT) notice on the software deadline extension (Spain, page updated 13 October 2026) says "las entidades que presenten el Impuesto sobre Sociedades deberán tener adaptados sus SIF antes del 1 de enero de 2027." (our translation: corporate taxpayers need their invoicing systems, SIF, updated before 1 January 2027) "El resto de obligados tributarios, antes del 1 de julio de 2027." (our translation: all other taxpayers, before 1 July 2027). Before you commit to any tool, ask its provider how it meets the Reglamento de sistemas informáticos de facturación (RRSIF) by the date that applies to you.
E-invoicing between businesses follows a separate timetable. The AEAT's e-invoicing timetable (Spain, page updated 13 October 2026) says "La obligación de emitir y recibir factura electrónica obligatoria será exigible:" (our translation: e-invoices become mandatory to send and receive) "A los 12 meses (6 de octubre de 2027), para grandes empresarios y profesionales, aquellos cuyo volumen de operaciones a efectos del IVA haya excedido de 8 millones de euros durante el año natural inmediato anterior." (our translation: after 12 months, on 6 October 2027, for large businesses, meaning those with more than €8 million of VAT turnover in the year before) "A los 24 meses (6 de octubre de 2028), para el resto de empresarios y profesionales." (our translation: after 24 months, on 6 October 2028, for every other business and professional). The same page sets dates for a second duty: "La obligación de comunicar el estado de las facturas y de los pagos será exigible:" (our translation: the obligation to report the status of invoices and payments will apply). For the rate, Article 90 of the VAT Act, Ley 37/1992 (Spain, BOE consolidated text last updated 7 October 2026) says "El Impuesto se exigirá al tipo del 21 por ciento, salvo lo dispuesto en el artículo siguiente." (our translation: the tax applies at a rate of 21 percent unless the following article says otherwise). The Spain invoicing guide linked below covers the reduced rates and the invoice contents in full. For your own position, ask an asesor fiscal.
Worked example, with sample figures in euros: a designer's €1,000.00 fee is taxed at the general rate. With the 21 percent rate from article 90, the IVA comes to €1,000.00 × 21% = €210.00, so the client pays €1,210.00. Try each tool and look for the base, the rate and the tax shown separately on its invoice.

The general IVA rate

What each invoice contains
Article 6 of Royal Decree 1619/2012 (Spain, BOE consolidated text last updated 31 March 2026): "Toda factura y sus copias contendrán los datos o requisitos que se citan a continuación" (our translation: every invoice and its copies will contain the details or requirements listed below). The Spain invoicing guide lists those details.
