For a software publisher, the electronic invoicing reform is not limited to a regulatory obligation: it is a strategic opportunity to strengthen its offering, to promise compliance to its customers and to offer services with high added value. However, choosing which approved platform (AP) to use or how to become Solution Compatible is not trivial.

This article explains the options available to a publisher, the key questions to ask before choosing a partner, and the criteria for a long-lasting, secure and scalable integration that allows you to stay focused on your business.

Why a software publisher must integrate electronic invoicing

As part of the French reform of electronic invoicingany company subject to VAT must, from September 2026be able to receive and then issue electronic invoices conforming to structured formats (e.g. Factur‑X, UBL, CII) and transmit tax and transaction data to the administration.

For a software publisher, this means:

  • guarantee its customers the regulatory compliance of their invoices;
  • offer an electronic invoicing service integrated into the tool (accounting, ERP, business management, GED…);
  • meet rapidly evolving technical, business and regulatory expectations (more than 20 mandatory mentions today, around 400 in the sights of future developments).

The issue is simple: if your customers do not have the guarantee of a compliant and sustainable service, they will be forced to go to another publisher or service provider.

6 key questions before choosing your PA partner or Compatible Solution

For a software publisher, not all partners are equal. Before committing, ask yourself these questions:

1. Is it a pure player in electronic invoicing?

You do not want a partner who also offers services that compete with your core business (for example accounting or management modules that could encroach on your market). A PA pure player focuses exclusively on regulatory infrastructure.

2. Is the partner sustainable and transparent?

The reform does not stop at 2026: the standards will evolve (mandatory information, formats, e-reporting). Ensure that the supplier commits to stable pricing conditions and continuous regulatory monitoring.

3. Does it cover all specific use cases?

Certain sectors (agencies, construction with retentions and subcontracting, ESN with project invoicing, etc.) have very specific requirements. Your partner must demonstrate its ability to manage these cases and carry correct aggregation and attribution in the correct tax period.

4. Is the platform scalable and international?

The volume of documents can be very large. A partner must manage massive flows (at IOPOLE, more than 150 million documents are processed per year) while supporting international interoperability. IOPOLE, for example, is Peppol Provider certified, facilitating cross-border exchanges.

5. Is the solution secure and integrable?

In addition to regulatory standards, security is crucial. IOPOLE has chosen hosting in Sovereign Cloudguaranteeing security and GDPR compliance. And finally:

⭢ Have your technical teams test the partner's integration APIs — a POC can be completed in a few hours to verify integration and functional suitability.

6. Possibility of White Label

If you want complete transparency, opt for a white label PA solution: 100% your brand: Iopole is invisible, you remain the sole contact for your customers.

In summary

For a software publisher wishing to integrate electronic invoicing:

  • Becoming a PA offers registration and full regulatory control, but requires significant resources and continuous monitoring.
  • Becoming a Compatible Solution is often faster, less expensive and strategic, because it allows you to offer a compliant service while remaining focused on your business.
  • Choosing a pure player, sustainable, secure and technical PA partner (API, sandbox, scalability, international) is a key success factor.

By choosing a platform like IOPOLE, you gain regulatory compliance, developer experience and operating security, while preserving your strategic positioning in your market.
