French E-Invoicing Is Already Here: What Should SAP Business One Users Do Now?
September 2027 may sound like the big deadline for French SAP Business One users. Although, for large businesses, e-invoicing compliance has already started, SMEs should start preparing now for what comes next.
As of September 1, 2026, all SMEs must be able to receive compliant electronic invoices. The following major milestone comes in September 2027, when businesses will have to meet the full e-invoicing requirements (receiving and sending).
For SAP Business One users, this creates an important window of opportunity:
Get familiar with the future requirements. Use the transition period wisely to prepare properly for tomorrow, which will arrive sooner than you can imagine.
Don’t wait for the final deadline
One of the biggest mistakes businesses can make is treating September 2027 as the date when they start setting the groundwork. The basics should be prepared in advance to avoid the last minute rush and redundant stress.
By then, your platform, company registration, invoice flows and SAP Business One processes should already be working together. You can start with a few concrete steps now.
1. Connect to an approved platform or pick a connected add on provider
Your first step is to make sure you have an appropriate approved platform selected or have the right add on provider.
This is about choosing an add on provider wisely not to miss on any key aspects in staying compliant. Think about how the SAP Business One add on will fit into your existing business processes.
For SAP Business One users, the important question is:
Can your e-invoicing solution exchange compliant invoices without creating another disconnected process outside SAP Business One?
If the answer is yes, you’re on the right path. Integrated add ons serve as the pathway for your electronic invoices without disrupting the system that’s already running or creating interface fatigue.
2. Complete your KYC/KYB requirements and document the process
Your approved platform will need the relevant company and legal representative information as part of the onboarding process.
Providing this information early and correctly removes one more potential bottleneck when invoice exchanges become mandatory.
3. Check your DGFiP directory registration
Your business needs to be correctly referenced in the DGFiP directory so that electronic invoices can be routed to the correct recipient.
In many cases, your accredited platform can manage or support this step — but it is still worth checking that your company information is correct and up to date.
4. Start testing your invoice flows
This is where compliance becomes an actual business process. Don’t wait until 2027 to find out whether your invoice workflows work as expected. Start with your first incoming and outgoing flows. Check:
- Can compliant invoices be received?
- Can the relevant invoice data be processed correctly?
- Can invoices be matched to the right business partners?
- Can information flow correctly into SAP Business One?
- Can invoice statuses and documents be tracked and archived?
- What happens when an invoice fails validation?
The earlier you test, the more time you have to fix the gaps.
Compliance today. Preparation for tomorrow.
The current requirements give businesses a transition period. Use it. Instead of implementing a solution that simply ticks today's compliance box, consider what your SAP Business One environment will need when full compliance becomes the rule in September 2027. That means looking at e-invoicing as part of your end-to-end document process, rather than as another external compliance tool. With cks.eINVOICE, SAP Business One users can prepare their e-invoicing processes around the requirements of the French mandate while building a setup designed for the next stage of compliance.
The goal is simple:
Don’t scramble when the next deadline arrives. Take the first compliance steps now. Test your invoice flows. Connect the process to SAP Business One. And use the transition period to build a solution that can take you through 2027 and beyond.
