Accountants can turn e-invoicing compliance into new service lines before September 2026
French accountants have until September 2026 to help clients receive e-invoices. A spring 2026 survey shows 38% of firms have no structured plan yet. Accountants can formalize diagnostic, platform selection, data prep, and training into billable service packages.
All VAT-registered firms in France must be able to receive e-invoices by September 1, 2026. A majority of accountants are seen as the primary source of guidance, but 38% of companies have no structured action plan yet. Accountants can convert this compliance deadline into recurring, billable service lines: diagnostics, platform selection, data quality, workflow mapping, training, and post-launch monitoring.
The September 2026 deadline creates immediate client needs
All VAT-registered companies in France must be able to receive e-invoices by September 1, 2026. Many business leaders mistakenly believe they have until 2027 to act, when mandatory emission for small firms is due. The reception deadline is sooner.
A spring 2026 survey by ECMA, CNOEC, and OpinionWay found that 62% of firms are operational or have an action plan in place. The other 38% have no structured approach with only months to go. The blockers are concrete and operational:
- Understanding emission and reception rules
- Choosing an approved platform compatible with existing software
- Registering and populating the national directory
- Cleaning up customer and supplier databases
- Reorganizing purchase, sales, and validation workflows
According to the same survey, 61% of companies name their accountant as their main source of information on e-invoicing, and 78% expect the accountant to play a decisive role in the transition. Accountants have natural credibility on cash flow management, but must act proactively or risk losing ground to other advisors.
Formalize e-invoicing support into a service catalog
As invoice collection and production become automated, accountants can shift effort from data entry to analysis, alerts, and risk management. This frees capacity for higher-value services. The e-invoicing reform is an ideal entry point to package and price services that were historically informal and absorbed into the base engagement.
Accountants can now offer:
- Readiness diagnostic: Review the client’s current tools, invoice volumes, archiving practices, approval workflows, and team digital maturity.
- Platform selection and security: Help choose an approved provider that fits the client’s accounting environment and ensures smooth invoice flow.
- Data and directory prep: Clean up SIRET, VAT, duplicates, and contact details to prevent invoice rejections.
- Workflow mapping and setup: Define who emits, approves, and pays; configure tools; test scenarios.
- Training and change management: Run workshops for leadership and admin teams to embed new practices.
- Post-launch monitoring and advice: Track rejections, diagnose errors, flag payment delays, and refine cash forecasting.
These services should be formalized as packs, fixed fees, or subscriptions with clear scope, task allocation, and a dedicated engagement letter.
Tools help accountants deliver and scale these services
Deploying a catalog of e-invoicing services requires method, client collaboration, and strong technology. Sage For Accountants centralizes the firm’s work around client files and links to production tools. GoProposal helps accountants build commercial proposals: select services, allocate tasks, price the work, and generate the engagement letter.
On the client side, accountants should guide firms toward integrated solutions. Sage Active consolidates quotes, invoices, payments, bank reconciliation, reporting, and accountant communication in one place. This avoids tool sprawl, improves data quality, and gives the accountant cleaner information to work with.
The Sage Approved Platform lets firms emit, transmit, and receive e-invoices within an ecosystem connected to Sage software and accessible via API. Tools like Sage Copilot can flag pending quotes, unpaid invoices, and follow-up actions, helping accountants intervene more often and earlier in the year.
