Duplication of efforts in manual billing has previously been unavoidable, costly and error-prone. Bills are usually created in electronic forms, printed and posted. At the recipient's end, paper bills are then re-entered into electronic systems and archived as online documents.
Yet it is possible to eliminate the duplication efforts and costs related to paper-based billing. With a qualified electronic signature, organizations can issue bills exclusively in electronic form, and submit them in digital form for tax deduction.
In order to further smooth the path for the integration of electronic billing into automated business processes, it has also been possible since January 1, 2004 to provide electronic bills en masse – and hence automatically – with a qualified electronic signature.
Exploit the tremendous savings potential that electronic bill handling has to offer. With the TC Signature Service we offer a cost-effective and extremely efficient solution for the production of qualified electronic signatures for documents in large volumes. We also enable you to check and archive documents in accordance with the principles for data access and for the verifiability of digital signatures (GDPdU).
