Objective comparison of the main invoicing software for freelancers in Spain in 2026, covering Verifactu compliance, price, features and vertical modules.
Choosing invoicing software in 2026 is not the same as two years ago. The Verifactu Regulation (RD 1007/2023) has changed the rules. From July 2026, all software must meet the AEAT's technical requirements — signed records, digital fingerprint chains, electronic submission and a mandatory QR code. In this article we compare the main options on the Spanish market using objective criteria to help you choose.
The most important criterion in 2026 is Verifactu compliance. The software must generate records compliant with RD 1007/2023, sign each record with a digital certificate, maintain an unalterable chain of digital fingerprints, send records to the AEAT and generate the mandatory QR code on every invoice. It is not enough for the vendor to say it will be ready: it must be certified and operational.
Beyond regulatory compliance, we evaluate ease of use (a freelancer should not need an accounting course to invoice), price (from free plans to 50 euros per month), included features (expenses, quotes, collections, bank reconciliation, VAT reports, multi-series, credit notes) and quality of technical support.
A criterion many overlook is the availability of vertical modules. Some businesses need sector-specific features — bookings for coworking spaces, clinical records for dental clinics, inventory management for retail. Most invoicing software is generic; only a few offer modules that avoid combining multiple tools.
CokuApp is a modular platform with Verifactu invoicing built into its design. It generates records, signs fingerprints, submits to the AEAT and generates the QR natively. Its modular model lets you subscribe only to the components you need — invoicing, CRM, memberships, bookings, clinical records — and it offers real vertical modules for coworking and dental clinics. Room for improvement: as a younger platform, it has fewer third-party integrations.
Holded is one of the most popular programs in Spain, with a complete ecosystem including invoicing, accounting, CRM, projects, inventory and HR. Its interface is modern and it has good bank integrations. Point to consider: full plans are pricey and the complexity may be excessive for freelancers who only need to invoice.
Billin is focused on freelancers and small businesses, with a simple invoicing flow and a free plan with basic features. It is a good option for those seeking simplicity. Point to consider: features are limited compared to more complete options and customisation choices are few.
Contasol is a program with a long track record in the Spanish market, aimed at freelancers and tax advisors. It offers a fairly complete free version with a solid accounting focus. Point to consider: the interface is less modern than recent alternatives and the learning curve can be steep for non-accountants.
Quipu combines invoicing with expense management and bank reconciliation. It excels at ticket scanning with OCR and bank connections for automatic categorisation. Point to consider: full plan pricing is comparable to broader options and some advanced features are only in higher tiers.
Anfix, developed by Wolters Kluwer, offers cloud invoicing and accounting backed by a group with extensive experience in tax software. A good option for those already using other tools from the group. Point to consider: the interface may feel less intuitive than more modern alternatives and the generalist approach does not cover vertical needs.
From July 2026, using non-compliant software is not an option. Penalties can reach 50,000 euros per fiscal year. Beyond fines, Verifactu provides full traceability (every invoice is recorded with a chained digital fingerprint), client trust (the QR lets anyone verify the invoice at the AEAT), and automated compliance (submission is automatic within the normal invoicing flow).
Verifactu is also the first step on a roadmap that will culminate in mandatory B2B electronic invoicing. Those already compliant with Verifactu will have the easiest transition. Choosing software that already has it built in natively is not just about compliance today — it is about being ready for what comes next.
CokuApp is not just an invoicing program with Verifactu bolted on. It is a modular platform where each business builds its own configuration by subscribing only to the components it needs. The invoicing system was designed from scratch with Verifactu built in — records are generated, signed, chained and sent to the AEAT as part of the normal invoice creation flow. No extra steps and no external middleware.
The modular model means you only pay for what you use — invoicing, CRM, memberships, bookings, clinical records. CokuApp also offers real vertical modules for specific business types such as coworking and dental clinics, something no other generalist solution provides. If your business needs more than basic invoicing, or you want the peace of mind of having Verifactu covered from day one, it is worth evaluating.
