As part of the government’s initiative to streamline invoicing processes nationwide, the IMDA has introduced e-invoicing among businesses, currently known as InvoiceNow. This initiative helps businesses speed up their operational process, improve payment cycles, and help reduce business costs in the long run.

Deskera is a proud member of the Certified Access Points and Solutions Providers. You can write to us for your request to join the PEPPOL network once you have successfully signed up your Deskera Books account.

We will assist you to register for a PEPPOL ID so that you can start using the InvoiceNow feature immediately. To find out more about the listed solution providers by IMDA, check this link here.
