E-invoicing and ERP: how to connect them without friction

Updated March 2026 - As the French deadlines of September 1, 2026 and September 1, 2027 approach, many companies are asking how to connect their ERP, invoicing tools, accounting environment and business workflows without launching an oversized IT project.

A compliant electronic invoice is not enough if the data does not move correctly between:

• ▸the ERP;
• ▸the sales tool;
• ▸the e-invoicing platform;
• ▸accounting;
• ▸cash management;
• ▸client follow-up.

No-code tools often make it possible to connect existing systems faster than a full bespoke development. In the right use cases, they help push data from one tool to another, trigger an alert or workflow, enrich invoice data with business fields and consolidate statuses.

Hayot Expertise insight: no-code is not a substitute for governance. Before connecting anything, document the fields, the source of truth, the VAT rules, the invoice statuses and the error cases.

Step 1. Map the target flow

Identify who creates the invoice, who validates it, who transmits it, who retrieves the status, who manages rejections and where the VAT data goes.

Step 2. List the critical fields

Typical examples include:

• ▸SIREN/SIRET;
• ▸client references;
• ▸payment terms;
• ▸net amount, VAT and gross amount;
• ▸transaction type;
• ▸sending and receiving statuses.

Step 3. Define the human control point

A finance automation should never remove human oversight entirely.

Step 4. Test before the deadline

Waiting until summer 2026 to validate the flows is a poor idea. Real-life testing needs to happen well in advance.

The administrative timeline remains clear:

• ▸September 1, 2026: reception obligation for all companies and issuance obligation for large companies and mid-sized businesses;
• ▸September 1, 2027: issuance obligation for SMEs, very small businesses and micro-businesses.

The goal is not to add one more connector for the sake of it. It is to create a flow that is reliable from VAT logic through status management to accounting and monitoring.

Prepare your ERP and e-invoicing flows before the 2026-2027 deadlines

Connecting e-invoicing and ERP through no-code can be highly effective when the project is driven by processes, VAT logic, status management and data controls rather than by tools alone.
