Building & construction
Dozens of sites, hundreds of suppliers, complex approval flows: in construction, correct invoicing is essential to keep your projects profitable. One mistake can mean delays in payments, discussions with subcontractors or loss of control over your cash flow. Yet many construction companies continue to work with manual steps and loose systems.
With e-invoicing through Nymus, you streamline the entire process without upending your ERP.

E-invoicing challenges
Do you recognize yourself in these situations?
As a construction group or contractor, you work with many suppliers, different legal entities and complex project structures. Quotations, POs, delivery notes and invoices must seamlessly fit together - but this is still often done manually.
Every yard has its own flow
Different VAT numbers, entities or PO structures cause confusion. Especially if invoices are not correctly linked to the correct yard or project.
Internal approval flows slow everything down
Invoices often have to go past several people for approval, depending on the project or budget. Manual follow-up makes this slow and error-prone.
Suppliers work with different formats
Some send UBLs, others scan in a paper invoice. Your administration figures out what belongs to which delivery.
International partners or governments require specific formats
Projects abroad? Government contracts? Then you have to deal with e-invoicing via Peppol, EDI or portals that your team has to complete manually.
