Reunion businesses miss electronic invoicing deadline; compliance lags far behind legal re

Electronic invoicing became mandatory for Reunion Island businesses on Tuesday, September 1st, 2026, but the gap between regulatory deadline and operational reality is already wide. Across the island’s commercial sector, awareness of the requirement has not translated into compliance, and the reasons are structural, not merely attitudinal.

At the Port, Cathie Buscemi, president of the Port merchants association, acknowledged she has not yet made the switch despite knowing about the requirement for a year. “We haven’t really dealt with it. We don’t really understand the purpose of the system which, contrary to what people want us to believe, is actually extra work,” she said. Her situation is not unusual.

Patrick Serveaux, president of the Union of Hotel and Restaurant Trades in Reunion (UMIH), organized webinars to help professionals adapt. Attendance was sparse. Posts and emails followed. Uptake remained sluggish.

The operational picture becomes clearer when the economic baseline is considered. Pierrick Robert, president of the Reunion Chamber of Commerce and Industry (CCIR), put it plainly: “A portion of Reunion’s businesses, particularly the smallest structures, already face numerous daily constraints: inflation, recruitment difficulties, cash flow problems, rising material costs. They are not yet ready for complete digitalization; the digital divide is substantial.”

Chakil Omarjee, vice-president of the Union of Merchants of Saint-Denis (UCD), pointed to the friction of switching systems mid-operation. “It’s not something easy to put in place when you have years of an existing system already running,” he said.

For very small enterprises (TPE), the burden is acute. Younous Adame, president of the Reunion Organization of Very Small Enterprises (ORTPE), described the structural reality directly: “Behind a TPE, there is no separate administrative department, no IT service, no legal team, no HR department, no accounting division. Very often there is one person doing everything.” That single operator must open the business, serve customers, manage suppliers and employees, handle banking and taxes, and still find time for administrative compliance. “Businesses were informed about electronic invoicing’s arrival. But being informed does not necessarily mean having the time and resources to prepare,” Adame said.

Cost is the second concrete barrier. The state system was initially meant to be free. Businesses must now choose from 150 private platforms, with fees ranging from dozens of euros monthly to integration within professional banking packages. Beyond platform costs sit expenses for software, training, and accounting support. The most overlooked cost, according to Adame, is the business owner’s time. “For a TPE counting every euro to maintain operations and jobs, a few euros here and a few euros there eventually add up. We must ensure this new obligation does not become an additional burden,” he cautioned.

The regulation applies only to business-to-business transactions involving VAT recovery; consumer invoices are unaffected. Even so, more than 100,000 enterprises across Reunion fall within scope, including artisans, merchants, independent professionals, small and medium businesses, and micro-entrepreneurs. Very small and small-to-medium enterprises face their compliance deadline in 2027.

Meanwhile, the rationale behind the mandate is not trivial. The stated objective is reducing unpaid invoices, the leading cause of business failure. The Bank of France recorded 18,000 business failures last year attributed to unpaid invoices. The reform is designed to address that. The implementation obstacles, however, remain real.

Katy Hoarau, president of Medef, argued the focus must shift from blame to support. “Today, the challenge is not to make businesses feel guilty, but to accompany them so they succeed in this transition under good conditions,” she said. The CCIR has run workshops for months. The administration has prepared practical guides and promised lenient enforcement through year-end for what it calls “good-faith laggards.” Technical requirements are detailed at https://imazpress.com/selection-de-la-redaction/facturation-numerique.

Business organizations are now speaking in pragmatic terms. The regulation exists, the timeline is fixed, and adaptation is inevitable. “We cannot tell our TPEs to wait hoping for a postponement or suspension. The question is no longer whether this will arrive, but how we organize to make it as simple as possible,” Adame said.

Whether the combination of workshops, guides, and lenient enforcement through year-end is enough to close the compliance gap before the 2027 deadline for smaller enterprises remains the open question.
