Digitizing invoicing is no longer optional for Spanish companies: it is a legal, operational, and financial requirement. Here, electronic invoicing systems integrated with ERPs are the most effective way to automate tasks, comply with regulations, and gain visibility into accounting processes. In this scenario, easyap is positioned as one of the strongest platforms on the market, integrating seamlessly with ERPs such as SAP, Sage, Microsoft Dynamics, Oracle and others. But what are the advantages of this integration between systems and electronic invoices? What type of connection is there with each ERP? We analyze this in detail below.
What does integrated electronic invoicing with ERP involve?
Electronic invoicing allows you to issue, receive, and store invoices in digital format with full legal validity. However, its true potential is realized when you integrate it with corporate ERP . This creates direct communication between the invoicing system and the purchasing, accounting, and treasury modules.
Broadly speaking, integrating electronic invoicing software with ERP involves:
- Automate invoice registration and approval.
- Reconcile orders, accounts, contracts, and delivery notes.
- Eliminate tedious repetitive manual tasks.
- Validate tax and accounting data in real time.
- Synchronize flows between different departments.
Integration comparison: easyap vs. other systems
The truth is that, with digital transformation, numerous invoicing systems have emerged. In addition, most of these electronic invoicing solutions on the market offer connections to ERPs.
However, there are differences between them, since not all of them guarantee real, deep integration. Easyap does (and with the big brands on the market), as shown in this table.
Comparison table: level of integration with corporate ERPs
| ERP | easyap | Generic solutions | Integration with easyap |
| SAP ECC / S/4HANA | Native integration | Partial, via files | Direct connection to MM, FI/CO, validation by order |
| Sage X3 / Sage 200 | High integration | Limited | Certified connector, accounting and tax integration |
| Microsoft Dynamics | Compatible with NAV, D365 | Basic or manual interface | API integration, real-time validation |
| Oracle EBS / NetSuite | Advanced connectivity | Costly adaptations | Automation of entries, flows between accounting modules |
| Customized ERPs | Flexible API adaptations | In many cases not feasible | RESTful API and custom connectors |
It is clear that easyap stands out for offering much richer technical, functional, and documentary integration, with validations, traceability, and reporting synchronized with the ERP.
In any case, we will now see how easyap, as an electronic invoicing system integrated with ERP, works hand in hand with the best solutions.
