Electronic invoicing is already a key requirement in business management in Spain. Having effective electronic invoicing software not only ensures legal compliance, but also improves efficiency, automates processes, and reduces errors.
But how do you know which solution is the right one? The choice should be based on criteria such as regulatory compliance, integration with other systems, ease of use, technical support, and scalability.
At iGEO, we know that every company is different. That’s why, in this guide, we explain how to choose the electronic invoicing software that best fits your real business needs.
Verify regulatory compliance
Before implementing an ERP for electronic invoicing, it is essential to verify that the software complies with the legal and tax regulations of the country or region in which the organization operates. Each territory has its own requirements for issuing, validating, and storing electronic invoices, so the system must be able to adapt easily to different regulatory frameworks. Make sure you start on the right foot.
Spanish legislation requires the use of electronic invoicing in all B2G (Business to Government) relationships since the entry into force of Law 25/2013, and its extension to the B2B environment will soon become mandatory under Law 18/2022, currently pending regulatory development. However, according to the Sage Spain report (2025), only 14% of Spanish SMEs are currently prepared to operate under mandatory B2B electronic invoicing, highlighting a significant gap in the digitalization of the business landscape.
In this context, the selected ERP must be certified and up to date with the regulations of the Spanish Tax Agency (AEAT) and other European tax authorities. Some essential aspects to consider include:
- Official certification or validation of the software by the local tax authority
- Compatibility with internationally recognized electronic formats (.xml, signed .pdf, .json, etc.)
- Inclusion of digital signatures and full transaction traceability
- Automatic updates in response to any legal or tax changes
An ERP adaptable to multiple regulations allows you to operate securely in different markets. Moreover, electronic invoicing software that does not comply with the law can result in financial penalties or errors in your tax reporting.
Integration with other tools and systems
An isolated ERP has limited effectiveness—it needs bridges that connect it to everything else. A good electronic invoicing solution should integrate easily with your existing tools: CRM, accounting systems, inventory control, project management, or payment platforms. Integration ensures that information flows smoothly, without errors or duplicated work.
Some advantages of an integrable ERP include:
- Automatic information flow between departments
- Reduced errors caused by data duplication
- Automation of repetitive tasks such as collections or reporting
- Real-time synchronization with tools like Microsoft 365, Salesforce, or HubSpot
At iGEO, we focus on native integration and an open API to connect your ERP with the tools you already use.
Technical support and updates
Technology alone is not enough—behind every ERP there must be people who support it. Technical support is essential to keep your electronic invoicing system running smoothly without interruptions. Choose a provider that offers:
- Fast, specialized support in Spanish
- Frequent system and regulatory updates
- Remote assistance or 24/7 chat support
An ERP without proper maintenance can quickly become obsolete and cause compatibility issues with the AEAT.
Ease of use: prioritize simplicity
The software must be intuitive and accessible to the entire team, without requiring advanced technical knowledge. A powerful tool is of little value if it is difficult to use. Look for a clean interface, simple navigation, and automations that streamline daily tasks.
Key criteria to consider include:
- Fast creation of invoices and quotes
- Visual dashboards with key indicators
- User-friendly interface adapted to non-technical users
- Interactive guides or in-platform tutorials
Easy-to-use electronic invoicing software saves training time and minimizes human error. iGEO’s ERP allows you to issue invoices, review financial statements, and manage collections from anywhere.
Immediate availability: desktop or mobile
In the digital era, mobility is essential. Make sure the ERP is available both as a web version and a mobile app. This allows you to issue invoices, review payments, or check financial reports from anywhere. Key benefits include:
- Full real-time control of your business
- Automatic synchronization across devices
- Secure access with multi-factor authentication
A cloud-based ERP guarantees immediate availability with daily updates and no user intervention required.
Custom configuration: adapt your ERP
Every company has different needs—so why should your software be the same as everyone else’s? Not all businesses require the same features. That’s why the software should offer customization options without the need for complex or additional development. A flexible ERP should allow you to customize fields, reports, users, and permissions, adapting seamlessly to your business model.
Recommended customization options include:
- Custom fields on invoices or quotes
- Differentiated user roles (administrator, accountant, sales representative)
- Automatically generated reports configured according to your KPIs
Customization improves efficiency and provides more relevant information for decision-making. A tool adapted to your daily operations multiplies team productivity.
Scalability: grow without changing your ERP
Today you may be an SME, but tomorrow you could lead your sector. Your company will grow, and your ERP must grow with you and be ready to stand out. Scalability is key to avoiding costly migrations in the future. Important aspects to consider include:
- Ability to add modules (accounting, inventory, HR, etc.)
- Capacity to handle more users and transactions
- Compatibility with new integrations or future versions
A scalable ERP is a long-term investment that ensures business continuity without disruptions. iGEO is designed to grow with you, with no limits on users or processes.
