Invoicing for the self-employed in Spain

The invoice creation process is optimized so that it can be completed in just a few minutes, thanks to our intelligent automation mechanisms. In addition, the program’s professional and intuitive visual interface provides a simple and efficient user experience.

Product and service catalogs

You can configure your catalog of services or products once and, when creating a new invoice, simply select the required item from the list. This eliminates routine actions and helps avoid manual errors. You can also manage delivery notes and commercial proposals as part of your document workflow, integrating these key documents into your daily operations.

Intelligent client database

The system automatically saves the data of each new client. The next time, you won’t need to manually enter the tax ID or address. Just start typing the client’s name, and the data will be filled in automatically. This significantly speeds up work and allows you to focus on serving your clients rather than entering data.

Complete document cycle

You can issue not only standard invoices but also simplified and corrective ones, with automatic control of series and numbering. Automation of invoicing and payment collection processes helps manage cash flow more efficiently and simplifies the administrative side of your work.

Modern invoicing software such as Conta.es allows you to automate not only invoice creation but also a significant part of accounting. This helps self-employed professionals focus on growing their business rather than routine administrative tasks.

Financial transparency and bank integration

We connect your invoices with the real movement of money.

Bank synchronization

You can connect your bank account to Conta.es and automatically link bank transactions with issued invoices. This allows you to easily track payments, see which invoices have already been paid and which are still pending.

The system also helps perform bank reconciliation and monitor the movement of money in your activity.

Payment links in invoices

You can connect a payment provider and add a payment link directly to the PDF of your invoice. The client will be able to pay for the service literally in one click, which significantly speeds up receiving the money.

The perfect combination: the self-employed and the accountant

Conta.es solves one of the most common problems in interaction with the accountant.

You can invite your accountant to the system. They will receive access to all your invoices and expenses in one place.

This means that there is no longer a need to send documents via WhatsApp or email. All information is available in the system 24/7, which eliminates file loss and significantly simplifies communication.

In addition, the system stores the history of documents and changes, ensuring transparency in accounting.

60-day trial period and a free plan to get started

We offer one of the most honest ways to start working.

60-day trial period

You can start using all the system’s features without entering your bank card details. We are confident in the product and give you two months so that you can test the system comfortably.

Free invoicing

After the trial period ends, you can stay on the free plan. It allows you to issue up to 10 invoices per month, which is perfect for self-employed professionals who are just starting their activity.

Switching to a paid plan

The process of switching to a paid plan is very simple.

If you need not only to issue invoices but also to manage accounting, or if you issue more than 10 invoices per month, you can switch to a paid plan.

The price of the plans starts from 9 euros per month, depending on the required functionality.

Compliance with Spanish legislation and electronic invoicing (AEAT and Verifactu)

Invoicing in Spain is regulated by a number of laws and regulations, including VeriFactu.

These rules define mandatory requirements for the creation, storage, and registration of invoices.

Electronic invoices will gradually become mandatory for self-employed professionals between 2025 and 2027. At the same time, documents must be stored for at least 4 years.

In addition, electronic invoices must guarantee the authenticity and integrity of the document through an electronic signature or other verifiable systems.

Conta.es is already fully prepared for these requirements. The system supports the transition to Verifactu for immutable invoice registration.

At the same time, flexibility is maintained. If for your activity or at the current moment the use of Verifactu is not mandatory, you can continue issuing invoices in the standard mode.

You choose the appropriate working format yourself.

Opportunities for working with international clients

Many self-employed professionals in Spain work with clients from different countries.

Conta.es supports several interface and document languages. You can issue invoices in English or Spanish and also use different currencies.

At the same time, all accounting information remains correctly structured for work within the framework of Spanish legislation.

Work from anywhere and on any device

Conta.es is an online service. All data is stored in the cloud and is available from any device.

This gives the self-employed greater mobility and faster customer service.

Imagine a situation. You are in the office and, for example, you are engaged in the manufacturing and installation of glazed terraces. A client calls you. While you are talking on the phone, you can already create and send an invoice.

Thanks to the catalog of services and products, where your work and prices are already added in advance, creating an invoice literally takes minutes. You select the service, for example “free technician visit for measurement,” and immediately send the invoice to the client.

You can do this in whichever way is most convenient for the client:

• via WhatsApp
• by email
• by sending a link

For the client this looks like an order confirmation: the work is accepted and the technician will arrive to take measurements.

For you this means another important advantage: you appear as a reliable and responsive professional who reacts quickly and works professionally. This seriously distinguishes you from competitors.

Automatic scanning of invoices and receipts

Automatic document scanning helps self-employed professionals record expenses more quickly.

Using the phone camera or by uploading a file, the system recognizes data from receipts and invoices thanks to OCR technology and artificial intelligence.

The system automatically extracts:

• date
• amount
• supplier
• expense description

This allows expenses to be digitized in a matter of seconds and avoids manual data entry.

This approach helps maintain order in accounting and significantly simplifies the preparation of tax reporting.

Examples of invoice templates

Invoice templates help self-employed professionals quickly create professional documents for clients.

The system offers ready-made invoice templates that already contain all the necessary elements:

• invoice number
• date
• client details
• description of services
• price
• total amount

This allows invoices to be issued quickly and without errors, and also guarantees that the documents comply with the requirements of Spanish legislation.

The use of templates significantly speeds up the work process and helps the self-employed appear professional in the eyes of the client.

All in one place — tax calculation

One of the most useful functions of the system is automatic tax calculation.

The system automatically calculates:

• VAT
• personal income tax (IRPF)
• other necessary tax indicators

This helps avoid errors and facilitates the preparation of tax reporting.

The system is also regularly updated in accordance with changes in legislation.

Development of invoicing systems

Modern invoicing programs continue to develop actively, and Conta.es is no exception.

A wider use is expected of:

• artificial intelligence
• automatic expense classification
• error detection

Data security also remains one of the key priorities, including the use of modern encryption and data protection methods.

In addition, multiplatform solutions allow accounting to be managed from any device.

Conta.es - a modern invoicing and accounting system — is a useful tool for self-employed professionals in Spain.

Such solutions help to:

• automate invoice creation
• record expenses
• calculate taxes
• maintain order in documents
