September 2026 is just a few months away. And yet, many managers of micro-enterprises and SMEs are still approaching the deadline with a vague intention to ‘sort it out’ — without having really got started. It’s not a lack of willingness: it’s simply that the information available is often technical, contradictory, or aimed at large corporations.
The result: the same mistakes keep cropping up, with the same types of people. Misunderstandings about what is actually mandatory, false starts based on the wrong solutions, and delays that make compliance more costly than it needn’t have been.
Here are the 5 most common mistakes — and what to do instead.
Mistake No. 1: confusing a PDF sent by email with an electronic invoice
This is by far the most common misconception. Many managers believe they are ‘already using electronic invoicing’ simply because they send their invoices as PDFs by email, or receive their suppliers’ invoices in the same way. This is not what the reform requires.
Under the reform, an electronic invoice is a structured data file — in Factur-X, UBL or CII format — which must be routed via an Approved Platform (PA) registered with the DGFiP. A PDF, even if signed or sent by email, will no longer be compliant once your suppliers switch to the new system.
⚠️ From 1 September 2026, your suppliers – whether large enterprises or mid-sized companies – will issue their invoices in a structured format. If you are unable to receive them via a PA, you will not be able to process them for accounting purposes or reclaim VAT.
What you need to do: check that your solution is indeed an officially registered Approved Platform — and not simply a PDF invoicing programme. The list of registered Approved Platforms is available on impots.gouv.fr.
Mistake No. 2: believing that the handover can wait until 2027
The reform timetable distinguishes between two obligations: receipt and issuance. Many micro-enterprises have taken it to mean that their obligation to issue receipts does not come into effect until 1 September 2027. The immediate conclusion: “I’ve still got a year to go.”
Error. The obligation to receive invoices applies to all businesses subject to VAT – whether you are a micro-enterprise or an SME – from 1 September 2026, with no exceptions based on size. This means that from that date onwards, your suppliers who have made the switch will send you invoices in a structured format. If you have not designated an Approved Platform to receive them, these invoices cannot be processed. Your accounts will grind to a halt, and so will your VAT reclaim.
The Finance Act for 2026 (Act No. 2026-103 of 19 February 2026) also introduced a new specific penalty: any company without a designated PA that is found to be non-compliant after a three-month compliance period is liable to a fine of €500, rising to €1,000 for each subsequent quarter of non-compliance.
What you need to do: activate receipt via an electronic invoicing platform before September 2026, regardless of your plans for issuing invoices. This is step 1, and it’s non-negotiable.

Mistake No. 3: choosing a solution without checking the platform’s actual status
The market has gone into overdrive. Many software providers are marketing themselves as ‘reform-compliant’ or ‘ready for 2026’. This is not the same as being an Approved Platform.
There are two types of solutions available on the market. Approved Platforms (APs) are registered with the DGFiP and can directly issue, receive and transmit tax data. Compatible Solutions (SC) rely on a third-party AP to ensure regulatory compliance — they therefore introduce an intermediary into the process.
This distinction has practical implications: an SC provides less visibility into the status of your invoices, depends on the quality of the connector with the third-party AP system, and can cause disruptions to the workflow if that connector malfunctions.
What you need to do: before signing up, check that the solution is on the official list of registered PA providers, and understand the difference between a native PA and an SC. To find out more: EDRM and e-invoicing: why managing them separately costs you time and money
Mistake No. 4: neglecting e-reporting because you only invoice business customers
Electronic invoicing (e-invoicing) applies to B2B transactions between French businesses subject to VAT. However, the reform has a second aspect that is often overlooked: e-reporting.
E-reporting involves electronically submitting transaction data to the tax authorities for transactions not covered by B2B electronic invoicing: sales to private individuals (B2C) and international transactions. It is not optional.
In practical terms, this applies to:
- any micro-enterprise that sells directly to private individuals (retail, catering, services, etc.)
- companies that carry out export business or deal with foreign customers
⚠️ The 2026 Finance Act has increased the fine for failure to submit e-reports to €500 per submission, up from €250 in the original text, with a cap of €15,000 per year (Article 1788 D of the General Tax Code).
What you need to do: identify your sales channels (B2B, B2C, exports) and check that your solution supports automated e-reporting, not just structured invoicing.
Mistake No. 5: waiting until September to start getting kitted out
This is the most common mistake, and often the most costly. Implementing an e-invoicing solution is not simply a matter of ticking a box in a software programme. It requires a certain amount of time: choosing the right solution, understanding how it works, updating supplier and customer databases (particularly SIREN numbers), and familiarising yourself with the new processes before the requirement comes into force.
Managers of micro-businesses and SMEs who are rushing to set up their systems at the end of August face two problems at once: staff are on holiday, and service providers are overwhelmed. Set-up is carried out in a rush, configuration errors are more common, and the first fortnight of September is spent rectifying issues rather than getting things up and running.
What needs to be done: start preparing now, even if the deadline still seems a long way off. Get the reception side up and running first — that’s the simplest step, and the most urgent. Then prepare for the broadcast in 2027 without any pressure.
Summary of the penalties provided for in the 2026 Finance Act
The Finance Act for 2026 (Act No. 2026-103 of 19 February 2026, Article 1737 of the General Tax Code) has tightened the penalty regime compared with the original text. The applicable amounts are as follows:
| Breach | Fine | Annual ceiling |
|---|---|---|
| Invoice not issued in electronic format | €50 per invoice | €15,000 per year |
| Missing e-reporting submission | €500 per transmission | €15,000 per year |
| No designated PA on reception duty | €500, then €1,000 per quarter | Progressive |
Good news: the law provides for a ‘right to make a mistake’ for a first offence. If you rectify the situation voluntarily or within 30 days of a request from the authorities, no penalties will apply. This ‘right to make a mistake’ does not exempt you from taking action — it simply gives you a window of opportunity to rectify the situation.

In summary
Electronic invoicing in 2026 is not a complex transformation for a micro-enterprise or SME — provided you avoid the mistakes that make it seem so. Confusing PDFs with structured invoices, waiting until 2027 to get set up, choosing a solution without checking its status, neglecting e-reporting, or putting it all off until the start of the new financial year: each of these mistakes comes at a cost — in terms of time, potential fines, or operational disruption.
The September 2026 deadline is set in stone. The first step — activating the service — is quick and easy. Now is the right time to sort it out.
