Issuing a corrective invoice and cancelling an invoice are not the same thing. They are two distinct operations with different requirements, different VAT consequences and different technical treatments in the new electronic invoicing systems. Confusing them can lead to loss of VAT deduction rights, errors in quarterly returns and problems in a tax inspection. This guide explains when each applies, what the regulations require and what happens in the system when either is used.

B2B e-invoicing and VeriFactu are not the same thing. They are two separate regulations with two different objectives, two different timelines and two different types of obligations. Yet confusion between them is extremely common — even among tax advisors and accounting firms. This guide definitively clarifies what each one is, who it affects and how they relate to each other.

Mandatory e-invoicing introduces invoice status fields — acceptance, rejection, payment — as a mechanism for traceability and late payment control. They are a valuable tool. But there is a technical and accounting risk that Position Paper No. 3/2026 by Economistas Contables EC-CGE identifies with precision: if those status fields are not managed correctly in the software, they can indirectly push businesses towards recording income and expenses at the moment of actual cash receipt or payment, rather than at the point of accrual. For advisors, accountants and economists, understanding this distinction is essential.

Mandatory e-invoicing is not just a Spanish matter. The entire European Union is in the process of digitalising B2B invoicing, driven by the ViDA (VAT in the Digital Age) initiative adopted in March 2025. But each country has arrived at this point via a different path — with different timelines, different formats and different platform models. For businesses operating across multiple European countries, understanding these differences is not optional: it is essential to avoid invoicing in the wrong format at the wrong time.

Mandatory e-invoicing is coming to Spain under Royal Decree 238/2026 — but there is a critical detail that many SMEs and freelancers miss: the 12, 24 and 36-month deadlines have not started yet. Everything depends on a Ministerial Order that is still going through a public consultation process. This guide explains who is affected, when, and what you need to do.

Spain is undergoing three simultaneous regulatory changes in invoicing that affect every business and freelancer. The problem is that many confuse them, mix them up or treat them as one. They are not. The SIF (Invoicing Computer System), VeriFactu and B2B e-invoicing are three distinct concepts, born from three different regulations, with three different objectives and three different timelines. This guide explains each one clearly, with their real deadlines and key differences.

There are two ways to issue an invoice without VAT in Spain: because the transaction is outside the scope of VAT, or because it is within scope but exempt. These are different situations with different fiscal consequences, and confusing them can result in invalid invoices, loss of input VAT deduction rights and problems in a tax inspection. Furthermore, when an exemption applies, the law requires the invoice to state the specific legal basis for that exemption. This guide explains the difference, what exemptions exist and exactly what must appear on the invoice.

If you are a freelancer or run a small or medium-sized business in Spain and have heard about RD 1007/2023, the VeriFactu Regulation or the "Anti-Fraud Law" without quite understanding what it means for you, this article is for you. We are going to explain — without unnecessary technicalities — what Royal Decree 1007/2023 requires, who it applies to, from when, and above all, what concrete steps you can take today to reach 2027 without surprises.

With the RRSIF (Regulation on Requirements for Invoicing Information Systems) coming into force in 2027, every invoicing program used in Spain must meet a list of technical requirements that go far beyond what most freelancers and SMEs are used to. It is no longer enough for an invoice to have the issuer's details, the concept and the amount: the system that generates it must now guarantee the integrity, traceability and immutability of every record, and the invoice itself must include new elements such as the tax QR code. This article collects all requirements in a checklist format so you can verify whether your current software complies — or know exactly what to ask your provider.

Real-time e-invoicing does not only serve VAT control. In countries where the tax authority receives the data of every invoice at the moment of issuance, that information also becomes a tool for enforcement: it allows instant identification of who owes money to whom and enables action on those trade receivables before they are collected. This article explains what is happening across Europe, which countries already use invoicing data to accelerate credit seizures, which do not, and what real consequences this has for business owners.
