In the construction sector, thousands of invoices circulate daily between main contractors, subcontractors and clients. G-accounts, reverse-charged VAT and chain liability play a central role. eConnect is DICO-certified and processes all these sector-specific requirements automatically.
Why eConnect for construction?
eConnect has been DICO-certified since 2019 and supports the DICO SALES005 standard that has been the e-invoice format in the construction sector since 1 January 2022. Invoices with G-accounts, reverse-charged VAT and chain liability are processed automatically. With partners such as 4PS and VanMeijel, eConnect is deeply embedded in the construction supply chain.
eConnect is DICO-certified and supports the DICO SALES005 standard format. Transformation between Peppol and DICO is automatic, so every party in the chain receives the correct format.
Automatic recognition and processing of G-account invoices. The IDR recognises G-account IBAN numbers (the distinctive "099" sequence) on PDF invoices and includes them as a separate field in the e-invoice.
For subcontracting, reverse-charged VAT is the standard. eConnect recognises reverse-charged VAT automatically and applies the correct VAT code (AE) in accordance with EN16931/NLCIUS.
Automatic enrichment with GLN codes (13-digit GS1 address codes). Invoices are linked to the correct delivery address in the supply chain.
The Dutch Chain Liability Act (Wka) is built into the invoice processes. G-account deposits reduce the risk of being held liable for payroll taxes and VAT of subcontractors.
The IDR (Intelligent Document Recogniser) converts PDF invoices to e-invoices, including recognition of purchase order numbers as reference. Line recognition automatically splits invoice lines.
eConnect works closely with the leading software vendors in the construction sector.
4PS is the sector partner for construction, civil engineering and building services. 4PS Construct runs on Microsoft Dynamics 365 Business Central and integrates via native API connection keys with eConnect. The integration supports Peppol, DICO and other procurement networks.
VanMeijel Automatisering has been a partner since 2023, with a strong position in the civil engineering and infrastructure sector. Via VanMeijel, 67 organisations have been onboarded, with a processing volume of approximately 80.000 invoices per month via PDF (OCR/IDR) and approximately 5.000 per month via XML/Peppol.
DICO stands for the Digital Information Platform for the Construction Sector (Digitaal Informatieplatform voor de Constructiesector). The DICO SALES005 format has been the standard for e-invoices in the construction sector since 1 January 2022. By being DICO-certified, eConnect guarantees that invoices are automatically transformed to the correct format, regardless of whether the sender or receiver uses Peppol BIS or DICO. Parties in the construction supply chain don't need to worry about format differences.
A G-account is a blocked bank account where the contractor or hirer deposits the estimated amount for payroll taxes and VAT. eConnect automatically recognises G-account IBAN numbers on PDF invoices (identifiable by the "099" sequence) and includes them as a separate field in the e-invoice via the NLCIUS G-account extension. The receiving software package can then process two partial payments: one to the G-account and one to the supplier's regular bank account. This requires the receiving software to support G-account processing.
For subcontracting in construction, reverse-charged VAT applies: the main contractor pays the VAT instead of the subcontractor. eConnect automatically recognises reverse-charged VAT on incoming invoices. The IDR detects the VAT percentage (0%) in combination with the reverse charge indication and automatically applies VAT code AE in accordance with the EN16931/NLCIUS standard. This ensures the invoice is correctly processed in the financial system without manual intervention.
Under the Dutch Chain Liability Act (Wka) a main contractor can be held liable for the payroll taxes and VAT that a subcontractor owes. By depositing the relevant portion of the invoice amount into the subcontractor's G-account, the main contractor reduces this risk. eConnect processes these G-account invoices automatically and ensures that the split between G-account and regular payment is correctly included in the e-invoice. In addition, a Statement of Payment Conduct can be requested as supplementary risk mitigation.
Yes, both are official partners of eConnect. 4PS Construct integrates via native API connection keys and supports Peppol, DICO and other procurement networks. VanMeijel connects via the PSB REST API and IDR for both PDF conversion and Peppol delivery. If you already work with one of these packages, the connection to eConnect can be set up quickly via a Remote Starter session.
