Welcome to TrueLink
Send electronic invoice
With TrueLink you can send electronic invoices to public institutions and companies with EAN number. Your company is not required to have an EAN number or be connected to the NemHandel network.
OIOUBL is a Danish standard which the Danish public sector has decided to use as their standard. Many Danish companies use this standard and require that their suppliers use it as well. With TrueLink your company can either send data in OIOXML, OIOUBL or in a fixed file format, and TrueLink will transform your format to the OIOUBL format.
TrueLink has no start-up costs and no subscription costs. Your company only pays for the invoices which are sent to the suppliers. The price per invoice starts at DKK 4,50 and decreases depending on the amount of invoice tickets you buy.
When you send an electronic invoice to public institutions or private companies with an EAN number, you can send it directly from your invoicing system by using our TrueLink Client Software.
You need to go through 4 steps to send your first electronic invoice to a public institution or private company with an EAN number.
