Must Paper or PDF Invoices Issued During the E-Invoicing Start-Up Period Be Recreated as XML?

Summary

A paper or ordinary PDF invoice issued because the electronic invoicing channel is temporarily unavailable remains effective for processing, payment, accounting and VAT deduction, provided it concerns a genuine transaction and contains the legally required information. The start-up tolerance protects business continuity, but it does not postpone or suspend the French e-invoicing obligation. [vatupdate.com], [vatupdate.com]
The French guidance does not appear to impose a systematic requirement to recreate every such invoice retrospectively as XML. Nevertheless, transmitting or regularising the same invoice through the approved electronic channel once the system becomes available is the preferred approach, particularly to ensure that the required invoice data reach the French tax administration. [impots.gouv.fr], [vatupdate.com]
Any subsequent electronic transmission must be treated as the same invoice, not as a new commercial invoice. Businesses should preserve the original invoice identity, prevent duplicate accounting, payment, VAT deduction and reporting, and maintain evidence of the technical incident, temporary process and compliance remediation.

France’s e-invoicing obligation and start-up tolerance

France’s domestic B2B electronic invoicing reform starts applying from 1 September 2026. From that date, all businesses within the scope of the reform must be able to receive electronic invoices. Large enterprises and intermediate-sized enterprises, known as ETIs, must also issue their in-scope domestic B2B invoices through an approved platform. Smaller businesses become subject to the issuance obligation from 1 September 2027. [economie.gouv.fr], [vatupdate.com]

The French authorities have nevertheless recognised that systems, platforms and business processes may not all operate perfectly from the first day. The practical start-up guidance therefore gives priority to maintaining economic activity, processing invoices, protecting payment flows and preserving VAT rights while businesses resolve genuine implementation difficulties. [impots.gouv.fr], [vatupdate.com]

This approach is a pragmatic enforcement tolerance, not a legal postponement. Businesses must continue implementing the required electronic circuit and must be able to demonstrate that any use of paper, email or ordinary PDF is temporary, limited and supported by genuine operational difficulties. Durable parallel invoicing processes or simple failure to implement the reform remain outside the intended tolerance. [vatupdate.com], [vatupdate.com]

Is a paper or PDF invoice still valid?

Where a technical or operational problem prevents the required electronic transmission, a supplier may use an alternative channel to ensure that the customer receives the invoice and that commercial activity is not interrupted. This may include paper, email, an ordinary PDF, an existing EDI channel or a customer portal. [impots.gouv.fr], [vatupdate.com]

An invoice transmitted through such a channel should not be rejected solely because it did not pass through the required electronic invoicing circuit. It may still be processed, recorded and paid, and it may support VAT deduction, provided that it corresponds to a real transaction and contains the information required under the ordinary French invoicing rules. [impots.gouv.fr], [vatupdate.com]

However, the use of an alternative channel does not satisfy the electronic transmission obligation for a supplier already subject to mandatory e-invoicing. It is therefore important to distinguish between the commercial and VAT validity of the underlying invoice and compliance with the separate obligation to transmit that invoice through an approved platform. [impots.gouv.fr], [vatupdate.com]

Must the supplier subsequently create an XML invoice?

The practical conclusion from the guidance is nuanced. It would be inaccurate to say that every paper or PDF invoice issued under a temporary continuity procedure must automatically be converted into XML at a later date.

The DGFiP guidance indicates that, when the expected electronic circuit could not initially be used, the supplier may subsequently transmit the same invoice electronically or otherwise organise its regularisation as soon as possible. This is intended to place the invoice in the expected electronic circuit and allow the relevant data to be transmitted to the tax administration. [impots.gouv.fr], [vatupdate.com]

For a business already subject to the issuance obligation, electronic transmission of the same invoice is described as preferable, but not systematically required. When an invoice is not subsequently regularised electronically, the business must nevertheless be able to show that it has pursued a genuine and active compliance trajectory. [impots.gouv.fr]

The appropriate answer is therefore:

Retrospective electronic regularisation should be performed where it is technically feasible and can be controlled properly, but the guidance does not establish an absolute requirement to recreate every continuity invoice as an XML file. Where no electronic catch-up is performed, the exception should be documented and supported by evidence of the implementation difficulty and the company’s remediation activity.

Regularising the same invoice rather than issuing a new one

Where the supplier decides to regularise, the later structured transmission should represent the same legal and commercial invoice. It should not be treated as a second supply, a second receivable or a new invoice issued for the same transaction. [impots.gouv.fr], [vatupdate.com]

As a practical control position, the electronic version should preserve:

the original invoice number;
the original invoice date;
the identity of the supplier and customer;
the original taxable amount;
the VAT rate and VAT amount;
the total amount payable; and
the original commercial references.

The structured invoice may be created in a supported format, such as UBL, CII or Factur-X, and transmitted through the supplier’s approved platform. The process should make clear that this is the electronic regularisation of a previously transmitted continuity invoice, not a new invoice requiring a second accounting or payment process.

Businesses should avoid cancelling the original paper or PDF invoice and issuing a newly numbered invoice solely because the electronic system has subsequently become available. Cancellation and reissuance should be used only where there is a genuine underlying invoice error or where the applicable platform rejection and correction rules require a new invoice. The start-up guidance focuses instead on electronically transmitting or regularising the same invoice. [impots.gouv.fr]

Duplicate prevention is the central control requirement

The article published by VATupdate, based on Revo’s interpretation of the French guidance, highlights a key operational principle: one commercial operation should produce one invoice record, one payment and one VAT outcome. [vatupdate.com], [vatupdate.com]

A later XML or structured transmission could otherwise result in:

two customer payments;
two accounts-receivable entries;
two sales or revenue entries;
duplicate output VAT reporting;
duplicate invoice data being transmitted to the administration; or
the customer recording the same invoice twice and potentially deducting VAT twice.

The supplier and customer should therefore use the original invoice number and other matching information to identify the electronic transmission as a duplicate representation or regularisation of the same invoice. The customer should retain only one invoice as the operational accounting reference and mark any additional representation as a copy, duplicate or continuity version. [impots.gouv.fr], [vatupdate.com]

Evidence needed to support the tolerance

A company relying on the start-up tolerance should maintain a dated and transaction-level audit trail. The evidence should demonstrate that the use of paper or PDF resulted from a genuine implementation or technical difficulty, rather than a decision to remain outside the electronic invoicing system. [vatupdate.com], [vatupdate.com]

The exception file should include, where relevant:

the original invoice and its unique number;
the date and channel through which it was sent;
the reason electronic issuance was not possible;
error messages and platform rejection statuses;
IT or provider support tickets;
communications with the approved platform or customer;
the affected legal entity, customer and invoicing flow;
the temporary continuity procedure applied;
the date and method of electronic regularisation, if completed;
evidence that the invoice was recorded and paid only once; and
the remediation owner and expected return-to-normal date.

The French authorities have indicated that penalties should not be applied automatically to businesses encountering genuine, documented start-up difficulties while pursuing a serious compliance trajectory. The tax administration will, however, distinguish such cases from inactivity, avoidance, failure to enter the system or the continued use of a permanent parallel paper or PDF process.

Recommended company policy

A defensible internal policy could state:

Paper or ordinary PDF invoices may be issued only as a temporary business-continuity measure where the required electronic invoicing channel is genuinely unavailable. Each affected invoice must be recorded in an exception register. Once the electronic channel becomes available, the same invoice should be transmitted electronically where technically feasible and operationally controlled. The electronic transmission must not create a second invoice, accounting entry, payment, VAT deduction or reporting outcome. Where electronic regularisation is not performed, the reason must be documented and supported by evidence of active remediation.

This balances business continuity with the French authorities’ expectation that companies actively transition into the approved-platform framework. It also avoids interpreting the start-up tolerance either too narrowly, by requiring the automatic recreation of every invoice, or too broadly, by treating paper and PDF as compliant alternatives throughout the tolerance period.

Conclusion

A paper or PDF invoice issued because the French electronic invoicing system was temporarily unavailable does not automatically have to be recreated later as XML in every case. The invoice remains effective for commercial, accounting and VAT purposes if it reflects a genuine transaction and contains the required information.

Nevertheless, the strongest compliance position is to transmit or regularise the same invoice electronically once the system becomes available, especially where this is necessary to ensure the transmission of the required data to the French tax administration. If retrospective electronic regularisation is not feasible, the business should document the exception carefully and demonstrate that it is actively moving toward full compliance.

The grace period should therefore be treated as a controlled start-up tolerance, not as a temporary authorisation to continue ordinary paper or PDF invoicing without remediation.
