The S-invoice service – a service offered by S-Public Services (Sparkassen-Finanzgruppe – Savings Banks Finance Group) in cooperation with the technical service provider crossinx and SaarLB – completely digitalises invoice processing. All invoices are transferred to a digital, automated and paper-free invoice handling process. The invoices are processed transparently and securely via digital approval processes. And what if your customer still insists on paper invoices, for example? The S-invoice service also offers a cost-optimised solution for this.
