Since the announcement of the implementation of Verifactu, dozens of programs claiming to be compliant have emerged, making it harder than it should be to distinguish which ones truly are. The word compatible appears on all websites and means different things depending on who writes it.
This comparison includes the most solid options in the Spanish market, along with the profile that fits each one. Before looking at any list of best invoicing software with Verifactu it is important to keep in mind a fact that changes the urgency of the matter: deadlines have been postponed to January 1, 2027, for Corporate Tax payers and July 1, 2027, for others, including freelancers.
What it means for a program to be adapted
There is no official registry of programs approved by the Tax Agency. What the regulation requires is that the manufacturer certifies through a responsible declaration that their product meets the requirements of Royal Decree 1007/2023 and Order HAC/1177/2024.
In practice, an adapted program must cryptographically chain invoicing records, prevent invoices from being deleted or modified without leaving a trace, maintain an event log, include a QR code on all invoices, and allow the export of records in standard format. Ideally, it should support both the mode with automatic submission to the Tax Agency and the mode without submission.
The programs, one by one
Holded
It is the most comprehensive option on the list and best addresses the scenario of those who do not want to separate invoicing from the rest of management. It includes invoicing, accounting, expenses, bank reconciliation, CRM, projects, inventory, human resources, and POS on the same platform, with the invoicing module adapted to Verifactu in all plans, regardless of the level contracted.
This last condition deserves attention, as it is not the norm. Several competitors reserve regulatory adaptation for certain plans, which forces users to upgrade their tariff to comply.
For freelancers, the entry-level plan is around 15 euros per month at regular price, with frequent promotions during the first few months. Business plans start at around 29 euros and include multiple users, recurring invoices, automated accounting, and SEPA remittances.
Its downside is that it offers more functionality than a very small business will use in the first year.
Best suited for: freelancers and SMEs looking to solve Verifactu without adding another tool.
Billin
A lightweight and very straightforward product, designed to ensure that issuing an invoice takes the minimum time possible and to always have a clear idea of what has been collected and what has not. The learning curve is practically non-existent.
Its limitation is that it is not a management system and does not intend to be, so if you later need complete accounting or inventory, you will have to move away from it.
Best suited for: professionals invoicing services with low to medium volume.
Anfix
It covers adapted invoicing and allows tax submissions directly from the platform, which differentiates it from pure invoicing programs. A good option when the relationship with the advisory service is close.
It falls short in inventory and project management.
Best suited for: service companies with a simple structure.
Declarando
It combines invoicing software with tax advisory specifically aimed at freelancers, focusing on maximizing deductible expenses. It takes a different approach than the rest of the list: it sells not just a tool, but a tool plus support.
This makes it more expensive than a straightforward invoicing program, but for those without an advisory service, it can be worthwhile compared to hiring both separately.
Best suited for: freelancers without advisory services who want to handle invoicing and taxation together.
Contasimple
One of the most economical options on the market, with a limited free version. It covers the basics competently.
The interface feels less polished than that of recent products, and some tasks require more steps than necessary. It is advisable to confirm what exactly the free plan includes in terms of regulatory adaptation, as this is the point where it varies the most between providers.
Best suited for: low-volume activity and tight budgets.
STEL Order
Especially strong in businesses with fieldwork, with a mobile application designed for use outside the office and management of budgets, work reports, and delivery notes in addition to invoices.
Outside of that profile, it loses advantage compared to generalist solutions.
Best suited for: technical service companies with displaced personnel.
FacturaDirecta and Cuéntica
Two reliable veterans. FacturaDirecta stands out for stability and sobriety, while Cuéntica offers an educational approach that explains the reasoning behind each operation, useful for those who have just registered.
Neither is the most powerful on the market, but both do well what they promise.
Best suited for: freelancers who prioritize clarity over advanced functionality.
How to decide
Three criteria guide the choice better than any feature table.
If you are going to grow, choose with two years in mind. Migrating invoicing with chained records is more cumbersome than migrating any program, so it is advisable not to have to do it twice.
Check that the adaptation is included in your plan. It is not enough for the manufacturer to have an adapted product. Ask if your specific plan includes it.
Test the corrective features before signing up. This is the function that will most change your way of working and the one that some products resolve the worst. Fifteen days of testing is enough to know.
