● Business offer — E-invoicing compliance

E-invoicing: receiving is in force, issuing is what you prepare now

Since 1 September 2026, every company, whatever its size, must receive its invoices in electronic form as soon as its supplier is required to issue them that way; the obligation to issue follows company size — 1 September 2026 for large and mid-sized companies, 1 September 2027 for small, medium and micro-enterprises. Your AI agent prepares that work: recipient directory, format and mandatory-mention checks before every issue, statuses reconciled, e-reporting prepared. The regulated transmission itself is carried out by the approved platform you select: Blue Lemon Agent is not an approved platform and replaces neither that platform nor Chorus Pro. Hosted in France, through local inference or an isolated resource. The configuration itself is signed off with your chartered accountant.

Where do we stand on the e-invoicing project?
Receiving: ready. The connection to your approved platform is tested, 12 structured invoices received and integrated with no re-keying.
Issuing: 412 customers on file, 361 resolved in the directory (registration number and billing address verified). 51 still to settle — the same trading name across several establishments, or a closed registration number.
The 51 are sorted by revenue: the first 9 account for half of what you issue.

And will our invoices go through without being rejected?
I ran your last 190 invoices through the pre-issue check: 174 would be accepted as they stand, 16 would be rejected — 11 for a missing delivery address where it differs from the customer's address, 5 for a missing customer registration number.
I have prepared the 16 corrections, line by line, plus the rule that prevents them at source.
Bringing that rule into force is signed: your chartered accountant approves it in a single review.

✦ In brief

A Blue Lemon Agent e-invoicing compliance agent prepares the connection of your sales software to an approved platform, maintains the recipient directory, checks the structured format and the mandatory mentions before every issue, reconciles the lifecycle statuses and prepares the e-reporting. The official timetable: since 1 September 2026, every company, whatever its size, must receive its invoices in electronic form as soon as its supplier is required to issue them that way; on that same date, large and mid-sized companies must issue their invoices electronically and transmit their transaction and payment data; on 1 September 2027, that obligation extends to small and medium-sized companies and micro-enterprisessource: impots.gouv.fr, page updated on 16 January 2026, consulted on 7 September 2026; entry-into-force dates set by article 91 of French law no. 2023-1322 of 29 December 2023 (finance act for 2024). Blue Lemon Agent is not an approved platform: only an operator registered by the French tax administration is authorised to transmit your invoices and your data. Hosted in France, through local inference or an isolated resource, architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity. The configuration is signed off with your chartered accountant.

The context

Why e-invoicing is the most firmly dated project right now

Most company projects slip. This one carries dates set by law — article 91 of French law no. 2023-1322 of 29 December 2023 (finance act for 2024): since 1 September 2026, a company must receive its invoices in electronic form as soon as its supplier is required to issue them that way. Within the scope of the reform, a scanned paper invoice or an ordinary PDF sent by e-mail does not count as an electronic invoice; outside that scope, the earlier invoicing rules continue to apply.

! The stakes

This is not an IT project, it is a data project. It takes a clean customer file — registration number and billing address verified for every recipient —, sales software able to produce a structured format, a connection to an approved platform, and the ability to read what that platform sends back. Each of those four points is usually discovered at the first rejection, which is to say too late. And handing that data — prices, margins, customers, bank details — to a consumer tool hosted outside Europe would mean solving one regulatory constraint by creating another.

Our answer

The agent takes the four points in the order they fall due. It resolves the directory and names the lines it could not settle rather than guessing; it checks the format and the mentions before issuing, on every invoice, not after the rejection; it reconciles every status returned by the platform with the original invoice; it assembles the e-reporting and checks it before transmission. It runs through local inference or an isolated resource hosted in France. The configuration — formats, mention rules, e-reporting scope — is laid out documented, dated, tested against your history, and signed off with your chartered accountant: that sign-off is what makes it defensible. What it does not do is stated as plainly as what it does: it transmits nothing in place of the approved platform, it decides no VAT rate, regime or exemption, and it reissues no corrected invoice without sign-off.

The decisive point

Your prices, your margins and your customers run through this flow: sovereignty & compliance

An invoice is not a neutral administrative document: it carries your pricing policy, your discounts, the list of your customers and your bank details. Here is how our agents' architecture protects it, invoice after invoice.

Local inference

The agent can run on a machine inside the company: no invoice, no price list leaves the network for a foreign cloud.

Hosting in France

Otherwise, a dedicated, isolated resource hosted in France under French law — your invoicing data: processing and access within the European Union targeted by the architecture.

Reduced extraterritorial exposure

Architecture designed to reduce exposure to extraterritorial legislation, location alone not being enough to guarantee immunity for your prices and your customers: our architecture depends on a subcontracting chain and remote access documented for the configuration chosen.

An isolated resource per client

No pooling: an environment strictly dedicated to your company and its invoice flow.

Encryption & controlled access

Encryption in transit and at rest, role-based access (RBAC), strong authentication and logging of transmissions and statuses.

AI Act: governed deployment

Strictly a support agent; the configuration is signed off with your chartered accountant; traceability and human oversight end to end.

What depends on the architecture chosen These points are not general guarantees: they are settled deployment by deployment, in the quotation.

  • The applicable location is that of the architecture set out in the quotation and verified before commissioning.
  • Local execution is announced only for the configuration explicitly described and accepted in the quotation.
  • The applicable isolation depends on the deployment mode set out in the quotation; no dedicated isolation is presumed.
  • The encryption mechanisms in transit and at rest, their components and key management are those documented for the architecture chosen.
  • Roles and permissions are configured and accepted for the identities and systems actually connected.
  • The events logged, their content, their retention period and who may access them are defined for the deployment chosen.
For companies subject to heightened requirements, SecNumCloud and dedicated hosting options are available. A single architecture is designed to answer both the GDPR and extraterritorial exposure.

The company in this demonstration

Fictional company

Kerloas Systèmes — a French software consulting and development company (NAF 62.0)

Sector
Computer programming, consultancy and related activities: time-and-materials work on client sites, fixed-price development, application maintenance on subscription
Headcount
45 employees, including 34 consultants and developers, 1 person in sales administration and 1 finance and administration director
Market served
112 active recipients: 38 project clients (large accounts on time and materials, smaller companies on fixed price) and 74 subscription-only clients; 6 clients established outside France
Invoicing volume
140 customer invoices issued per month — 34 time-and-materials lines from timesheets, 10 fixed-price milestones, 96 maintenance subscriptions — and 60 supplier invoices received
Tools in place
A timesheet tool that feeds invoicing, sales management software for milestones and subscriptions, accounts kept by the practice
Who decides
The finance and administration director arbitrates; the practice's chartered accountant signs off the configuration
The improvement points
96 of the 140 monthly invoices carry a licence and a maintenance service on one and the same line, without distinguishing the nature of the operations; and the option for paying the tax on invoicing rather than on collection, exercised in 2019, appears on none of the invoices

Kerloas Systèmes is a French small company, and the obligations described here are French ones — no equivalent duty is implied for companies established elsewhere. Since 1 September 2026 it must receive its invoices in electronic form as soon as its supplier is required to issue them that way, and its own obligation to issue falls on 1 September 2027. Four of its time-and-materials clients are large accounts which have themselves been issuing since September 2026 — so receiving is not theoretical. The agent is connected to the timesheet tool, to the sales management software and to the approved platform the company selected; it prepares, it does not transmit in place of the platform, and the configuration goes through the practice's chartered accountant.

This company, its figures and the exchanges that follow were invented for the demonstration. They illustrate a common situation; they describe no real client.

E-invoicing compliance assistant · hosted in France
First week under the new regime: here is where you stand, and your problem is not the one you are preparing for.
· Receiving works: 9 structured invoices arrived this month from your four large time-and-materials accounts and were integrated without a single re-keying.
· Issuing is your project, and it falls in 2027: you are a small company, your obligation to issue lands on 1 September 2027. Twelve months — you need three, and not for the technology.
· The real subject is in your subscriptions: I put your 140 invoices for the month through the check the platform will apply. 27 would be rejected, and 19 of them for the same reason — a subscription line that invoices a licence and a maintenance service together, without saying which is a good and which is a service. The nature of the operations is one of the four new mandatory mentions, and as things stand it cannot be determined.
· Second reason, quieter: in 2019 you opted to pay VAT on invoicing rather than on collection. That is also one of the four new mandatory mentions, and it appears on none of your 140 invoices.
· What I propose this week: the rule that splits subscription lines. It settles 19 rejections out of 27, and it costs not one line of code in your timesheet tool. state-of-play_first-week.pdf140 invoices · 27 simulated rejections · 2 mentions at fault
⛓ Sourced · 140 invoices from 01/08 to 31/08, the platform's check set, the month's inbound flow
Hold on — when exactly does this concern us? Everyone keeps saying 2026.
Two dates, and only one of them gets quoted — that is where the confusion comes from.
Since 1 September 2026: every company, whatever its size, must receive its invoices in electronic form as soon as its supplier is required to issue them that way. You, like everyone else. That is done.
On that same date: large companies and mid-sized companies must issue their invoices electronically and transmit their transaction and payment data to the tax administration. That is not you — it is your four large time-and-materials accounts, and that is why 9 structured invoices have already arrived.
On 1 September 2027: that obligation to issue and transmit applies to small and medium-sized companies and to micro-enterprises. That is your date.
The category is read within the meaning of article 51 of the French law of 4 August 2008; the dates themselves come from article 91 of the finance act for 2024. These are French obligations, and they are described here as such. official-timetable_impots-gouv-fr.pdf3 deadlines · source cited and dated

Use cases

The six compliance workstreams, taken one by one

Each use case matches an agent we deploy. All of them work in support: the configuration is signed off with your chartered accountant.

Included in your agent The 6 capabilities essential to this promise are included, at no extra cost.
From 966 € excl. VAT / month

Connection to the approved platform

Building the selection case, preparing the flows from your sales software and running test batches before the switch. The connection itself and the regulated transmission are carried out by the approved platform you select.

Recipient directory

Checks each customer's French company identifier (SIREN) and billing address; identifies and classifies unresolved entries.

Structured format checks

Checks on the structured format produced by your sales software. The format used — Factur-X, UBL or CII — is the one your software and your platform actually accept: no format is announced as supported before it has been tested on your own chain.

Mandatory mentions verified

Supplier and customer registration numbers, issue date, delivery address when it differs from the customer's.

Lifecycle statuses

Submitted, received, rejected, paid: every status returned by the platform is reconciled with the original invoice.

E-reporting prepared

Transaction and payment data, scope, frequency and consistency checks before transmission.

Controls and safeguards These 4 controls are built into the agent: they frame what it does, whatever plan you pick. They are not chosen and are not added to your order.
Human validation, exceptions and escalation Status, safe closure and audit trail Reconcile supporting documents, rules and accounting entries with an audit trail Handle discrepancies and validations before any accounting entry or payment
What the agent must be connected to This connection is required for the agent to work. It concerns your information system and is scoped during the audit.
Integrate with accounting and banking software and with approved platforms (French e-invoicing)
The gain

How much time does compliance take?

Most of the effort sits in the customer reference data and in the pre-issue checks — two repetitive jobs. By taking them on, the agent shifts human time towards arbitrating the unresolved cases. The size of the gain depends on the state of your customer file and your management software.

If adapting the AI agent to your constraints, your needs or your requests requires other paid components — a third-party publisher's software licence, paid API access to one of your applications, hosting of health data, for which French law requires an HDS-certified host (art. L. 1111-8 of the French Public Health Code), SecNumCloud-qualified hosting, a speech synthesis service, particular hardware —, they are offered to you as an option or on quotation and re-invoiced at the cost incurred; nothing is committed without your written agreement. Where the artificial intelligence model you choose entails an additional cost, that cost is shown to you before you order and re-invoiced to you at the cost incurred, with no margin.

Frequently asked questions

Your questions, our answers

When is my company concerned?
Two dates, and they are not the same. Since 1 September 2026, every company, whatever its size, must receive its invoices in electronic form as soon as its supplier is required to issue them that way; on that same date, large and mid-sized companies must issue their invoices electronically and transmit their transaction and payment data to the tax administration. On 1 September 2027, that obligation to issue and transmit applies to small and medium-sized companies and to micro-enterprises. Your company's category is read within the meaning of article 51 of the French law of 4 August 2008 on modernising the economy. Source: impots.gouv.fr, page updated on 16 January 2026 and consulted on 7 September 2026.
Is a PDF sent by e-mail enough?
No, not within the scope of the reform. A scanned paper invoice or an ordinary PDF sent by e-mail does not count as an electronic invoice there: invoices travel through a platform approved by the administration, in a structured format. Outside that scope — transactions with consumers, suppliers not yet subject to the obligation to issue — the earlier rules continue to apply. The agent produces the structured format from your sales software, without changing the way you invoice or your layout.
Does the agent choose the approved platform for me?
It builds the case and lays it out with figures: formats accepted, status feedback, connection to your management software, hosting, historical data migration. Signing the contract is yours, and the configuration that follows is signed off with your chartered accountant.
What does the agent do if the platform rejects an invoice?
It reconciles the returned status with the original invoice, names the reason for rejection, prepares the corrected invoice and proposes the rule that prevents that reason at source. You keep the decision to reissue. A rejection is never left without follow-up or without a readable reason.
Do we have to change sales management software?
In the vast majority of cases, no. The agent connects to the main ERPs and sales management tools as well as to the approved platform you selected; the integration scope is settled during framing, without forcing a migration.
How long does deployment take?
The lead time depends on the integrations to be built — sales software, accounting, approved platform — and on the state of your customer file. It is settled during framing, after a free audit that measures that state, then a design, integration and testing phase, and a configuration review by your chartered accountant before go-live. We do not announce a duration before that measurement.
Is Blue Lemon Agent an approved platform?
No. An approved platform is a dematerialisation operator registered by the French tax administration for a renewable three-year term; only a registered operator is authorised to issue, transmit and receive electronic invoices and to transmit data to the administration. Blue Lemon Agent is not registered and is not applying to be: the agent prepares your flows, checks them and hands them to the approved platform you have selected. The administration publishes two separate lists — operators that are registered, having passed the interoperability tests, and those whose application is complete but whose registration is still pending. Source: impots.gouv.fr, page updated on 3 September 2026 and consulted on 7 September 2026.
Which formats are actually supported?
Those your sales software produces and your platform accepts, observed on your own chain during the testing phase — Factur-X, UBL or CII as the case may be. We publish no list of guaranteed formats: a format is declared supported only after a dated test batch on your own invoices, and the result of that test batch is handed to you.
How do e-invoicing and e-reporting differ?
E-invoicing is the invoice itself, exchanged between two taxable companies through approved platforms. E-reporting is the transaction and payment data transmitted to the administration for operations that do not travel as an electronic invoice — sales to consumers, operations with clients established outside French territory. Payment data is added to that, and its exact scope depends on when VAT becomes due on your operations: the agent lays the question out, it does not settle it. The agent prepares both and keeps them explicitly apart in every case file; where the qualification of an operation is uncertain, it is flagged as such and is not settled on its own.
Does the agent transmit an invoice without sign-off?
No. The agent assembles the case file, runs its checks and prepares a submission draft carrying an idempotency key; releasing it for transmission requires sign-off by an authorised person, and the regulated transmission itself is carried out by the approved platform. A status returned by the platform is recorded as a dated observation: it is never inferred from an absence of reply.
