Operating across multiple markets means dealing with different rules, standards, and IT systems, often completely unlike those of your home country. For international companies, this can translate into greater document management complexity, incompatibility between data formats, and ERP integration challenges.
A-Cube’s API solutions are designed to overcome these barriers. Below are the key A-Cube APIs that global businesses can integrate to simplify workflows, automate complex procedures, and minimize errors.
1. Exchange Documents with the Peppol API
Peppol (Pan-European Public Procurement On-Line) enables companies and public administrations in different countries to exchange documents, data, and electronic invoices through a certified and secure network.
By allowing the sending and receiving of invoices between systems with different e-invoicing standards, Peppol is emerging as the global standard for both B2G (Business to Government) and B2B (Business to Business) transactions.
In Italy, Peppol can be accessed through certified access points such as A-Cube, which is also part of the Peppol eDelivery Network.
A-Cube’s Peppol platform allows users to manage various types of documents—invoices, credit notes, purchase orders, order responses, and shipping notices—in real time, ensuring instant sending and receiving without delays or queues.
It automatically handles document compliance processes and validations, integrates seamlessly with company systems, and is scalable for organizations of any size.
With the A-Cube API monitoring dashboard, international companies can also track usage and consult total or VAT-based statistics. From there, webhooks can be easily configured to define how the platform interacts with other enterprise systems.
This means companies operating in multiple countries no longer need to worry about technical or regulatory discrepancies—Peppol becomes a common language that bridges geographical distances and legal differences.
2. E-Invoicing API for Belgium and Poland
Cross-border invoicing can introduce multiple challenges. As tax rules differ from country to country, companies often face complex compliance requirements, and the risk of errors or penalties due to unfamiliarity with local regulations is high. These inefficiencies can slow down operations and expose businesses to delays, fines, or disputes with local authorities. A-Cube’s E-Invoicing API allows companies to send compliant electronic invoices not only in Italy, but also in Belgium and Poland. Organizations with commercial relationships in these countries can use it to automate the exchange of e-invoices in XML or JSON format. Thanks to webhooks, it integrates easily with existing ERP and business systems, synchronizing document flows. In addition to ensuring automatic compliance, it is suitable for startups and large enterprises alike and enables digital preservation with legally compliant e-signatures under Italian law.
3. A-Cube E-invoicing App for Stripe
For companies using Stripe, the A-Cube App for Stripe automatically creates compliant invoices for every marketplace transaction. Data generated on the payment platform are converted into standard XML and automatically sent to the Italian Tax Exchange System (SdI). By simplifying the invoicing process for online sellers, this integration reduces manual errors and saves administrative time.
The dashboard also allows in-depth invoice monitoring, including the ability to identify and correct rejected documents. The API supports both Italian and foreign VAT numbers, with automatic VAT number validation. No technical expertise is required for installation or use—it’s a plug-and-play solution, ideal for freelancers, e-commerce businesses, startups, and companies operating with Stripe.
In short, it’s a professional, tax-compliant solution for anyone selling online in Italy—without extra complexity.
4. From foreign PDF invoice to compliant XML
For accounting departments in Italian companies operating abroad, managing foreign PDF invoices can easily become a bottleneck.
Since July 2022, under the esterometro regulation, transactions involving non-VAT-registered entities must be reported in XML format via the SdI.
Traditionally, this required manually opening the PDF, verifying data, uploading it to the ERP, and generating a compliant self-invoice (autofattura)—a time-consuming and error-prone process due to format inconsistencies and lack of standardization.
A-Cube’s conversion service solves this problem by automatically converting foreign PDF invoices into compliant XML self-invoices under Italian law.
Here’s how it works: whether scanned or digital, the file is processed by an AI recognition system.
An advanced machine-learning algorithm, developed in partnership with Konica Minolta, identifies key invoice fields—amounts, dates, headers, and more—and automatically generates an XML file ready for SdI submission.
Validation and transmission are simple and intuitive: the user receives a notification, reviews the file, approves it, and sends it to the SdI or archives it.
The advantages are clear: the service works with any digital or paper-based document, is fast and secure, and performs legal, real-time conversion in just seconds—followed by a final user verification step.
5. A-Cube Transfer
Managing international document exchange—sending and receiving data between companies and institutions—often presents daily challenges.
Different ERPs and software systems use different formats and rules, making interoperability difficult.
A-Cube Transfer was created to resolve this complexity while maintaining full compliance with regulatory standards.
Through A-Cube Transfer, companies can send and receive files by connecting to internal or external systems.
The service can extract the necessary information from any file type to generate compliant digital documents—such as e-invoices, receipts, purchase orders, or delivery notes.
Once processed, the files can be sent to the SdI, the local Tax Authority, or the company’s ERP system.
A-Cube Transfer accepts multiple input file types, including Excel, EDI, CSV (single or multiple documents), ZIP archives containing XML, JSON, or CSV files, and digitally signed P7M files using any of these formats.
Another key advantage is ease of integration: the API can be installed within minutes into existing management flows—even without advanced technical skills.
A-Cube APIs: The Winning Ecosystem for International Companies
APIs are far more than just technical tools.
For international organizations, they are strategic accelerators that automate complex workflows, ensure compliance across markets, and minimize the risk of document discrepancies.
By integrating A-Cube’s API solutions and building an API-centric ecosystem, companies can lower operating costs, optimize internal processes, and accelerate their expansion into new markets—or strengthen their competitive position in existing ones.
