There is frequent confusion among sole traders taxed under the objective estimation system (known in Spain as *módulos*): if income tax is determined by objective parameters rather than actual turnover, does the anti-fraud regulation really apply to their business? The clear answer is yes: freelancers in modules are subject to AEAT's billing software rules whenever digital systems are used.
To understand the actual scope of this requirement, it is essential to examine the criteria established by the VeriFactu Regulation (Royal Decree 1007/2023) and how it affects hospitality, retail, and local service providers.
When does VeriFactu apply to a freelancer in modules?
The VeriFactu framework does not differentiate between income tax regimes; it regulates the technological systems used to issue invoices. The core rules are:
* Use of billing software or digital POS: If you use any computerized software, digital point-of-sale (POS) terminal, or electronic invoicing application to generate standard or simplified invoices (receipts), that system must guarantee integrity, traceability, and chained transaction logs.
* Manual paper invoicing: Freelancers in modules who exclusively handwrite paper invoice books are not legally compelled to purchase a digital billing system. However, the moment any digital tool is adopted to issue invoices, full compliance is mandatory.
* Client invoice requests: While many businesses under modules deal with retail consumers, issuing an invoice when requested by a customer or when carrying out B2B services requires compliant electronic records if produced digitally.

Official compliance deadlines
The Spanish Tax Agency (AEAT) has laid out a phased rollout schedule:
1. January 1, 2027: Mandatory implementation deadline for corporate entities (legal persons).
2. July 1, 2027: Definitive deadline for self-employed individuals (sole traders), including those under objective estimation or the equivalence surcharge.
Even though the deadline for freelancers is mid-2027, preparing software systems early prevents last-minute technical hurdles.
Modernizing legacy workflows and data migration
Many small operators previously recorded daily sales in basic spreadsheets or outdated local tools. Under the new rules requiring tamper-proof hash chains and QR codes, generic spreadsheets do not meet billing software standards. In this scenario, learning how to importar Excel a VeriFactu is essential to transfer customer and product catalogs seamlessly.
Similarly, businesses upgrading legacy setups may choose to importar Factusol a VeriFactu, or transition records when deciding to importar Sage 50 or importar Holded into modern cloud-first platforms. From an architecture standpoint, software developers can leverage a pasarela VeriFactu para software or interface their POS directly via an API VeriFactu to secure a frictionless integración ERP VeriFactu.
