Graneet announces a fundraising of 7 million euros to accelerate its ERP intended for construction SMEs. Since September 1, 2026, all companies must be able to receive electronic invoices; SMEs will, in turn, have to issue them from September 2027. The startup wants to make this regulatory constraint the entry point for broader management software: purchasing, invoicing, profitability, planning and site operations.
An invoice is never just an invoice on a job site. It may refer to a quote modified en route, to a delivery to be compared to an order, to a work situation, to a retention of guarantee or to the payment of a subcontractor. It often arrives too late to avoid the drift it reveals.
It is in this area, where administration, works and treasury meet, that Graneet announces a fundraising of 7 million euros. Founded in 2020 and based in Paris, the company offers ERP to construction SMEs and has nearly 1,500 customers. The operation must finance new modules, as well as the deployment of AI agents connected to management data.
The founding team brings together Jean-Gabriel Niel, who manages the company, Enzo Dozias and Raphaël Moulin. Graneet raised 2.4 million euros in 2021, then 8 million euros in series A in 2023, with the support of Point Nine and Foundamental, joined on this occasion by Axeleo Capital and Raise Sherpas. Among the individual investors are Nicolas Dessaigne and Jean-Christophe Taunay-Bucalo. The announcement of the new financing of 7 million euros does not, however, specify the identity of the participants in this operation.
The generalization of electronic invoicing does not create a need for software in the building sector; it has already existed for a long time in the form of historical ERPs, Excel files, costing tools, accounting software and site monitoring solutions which speak more or less well. However, it requires each company to choose through which system its invoices will now circulate. For Graneet, this obligation is the opportunity to become the point where this data ceases to be administrative and becomes operational again.
The electronic invoice, an obligation that goes up the entire construction site chain
Since September 1, 2026, all French companies must be able to receive electronic invoices. SMEs, VSEs and microenterprises will have to issue them from September 1, 2027. The timetable is known, but its consequences remain very concrete for construction companies: a supplier invoice can no longer be treated as an isolated document, then transmitted to accounting at the end of the month. Our analysis of companies lagging behind on this shift reminds us in particular that dematerializing an invoice is not enough to satisfy the new regulatory framework.
Construction adds its own complications, status invoices follow the actual progress of the work; additional work modifies the initial scope; withholding security and self-liquidation of VAT are part of the daily life of many companies; subcontractors introduce other flows and other controls. In this context, regulatory compliance is not just about choosing a dematerialization portal.
Graneet specifically wants to link the invoice received to the purchase order, to delivery, to the project budget and, ultimately, to the margin actually generated. It is this promise that distinguishes a compliance tool from business software. The first responds to an obligation, while the second must help the manager to understand, before the closure of the project, why his result differs from the initial estimate.
Pennylane for compliance, Graneet for business flow
The company does not present itself as a fully-fledged approved platform, it relies on Pennylane for this regulatory layer and positions itself as a compatible solution: invoices are received and transmitted within the framework provided by the reform, then integrated into the ERP processes. The accounting publisher itself intends to take advantage of the reform to broaden its control over management flows, a strategy analyzed when Pennylane raised 75 million euros.
This sharing of roles is strategic, the approved platform carries the infrastructure, the transmission requirements and the interconnection with the public system. Graneet seeks to maintain the daily relationship with the company: estimate, purchase, invoice, follow up, control expenses and monitor margins.
In practice, electronic invoicing can work both ways. It can strengthen accounting publishers and platforms that already have the compliance relationship. It can also give an advantage to vertical software capable of integrating this compliance into a more readable business experience.
From margin monitoring to construction site ERP
Graneet already covers costing, quotes, purchasing, invoicing, labor, inventory, CRM and profitability monitoring per site. The announced modules (scheduling, after-sales service, dashboard and API) outline a broader ambition: to become the operating system for construction SMEs, from the first costing to after-sales.
After-sales service extends the software beyond delivery to the site, and the programming interfaces must make it possible to connect it to accounting software, banks and payroll tools that are already installed at clients’ premises.
The French market remains very fragmented, Sage Batigest, EBP Bâtiment and Codial have long occupied the sectoral management software field, with installed bases, integrators and proven accounting connections; at the other end, tools like Obat or ProGBat are aimed more directly at craftsmen and small structures with simpler offers for quotes, invoicing and site monitoring. Between the two, Graneet targets SMEs already faced with the multiplication of purchases, subcontractors and work situations. Its competition is therefore not limited to building ERPs: it also comes from accounting software, electronic invoicing platforms and the very common assembly of several specialized tools. This recomposition is already visible in self-employed accounting, where the approved platform is gradually becoming a point around which the management software is redesigned, as shown by our comparison of Indy, Tiime and Abby.
AI is only as good as the data it can verify
Graneet also indicates that it has launched an MCP, an interface intended to make ERP data accessible to AI assistants, as well as agents specialized by profession: financial director, works manager, administrative assistant or accountant.
The use cases are easy to identify; a manager can ask which projects show margin drift; a works manager can identify unreconciled expenses or discrepancies between orders and invoices; an administrative team can prepare reminders or search for information without navigating through several screens.
But the value of an agent will not be measured by the quality of its formulation, but will depend on the quality of the data available, the rights granted to each user and the possibility of tracing back to a document, an order or an accounting entry. An agent who makes information more accessible can save time. An agent who acts on poorly informed data only accelerates the error. On a larger scale, this shift from ERP to an infrastructure of data and agents is also found in SAP’s strategy, which seeks to preserve its central role in the age of autonomous assistants.
