Q3. How do I activate InvoiceNow and/or GST InvoiceNow?
For InvoiceNow only
Please email [email protected] to start the activation process.
For GST InvoiceNow only
Go to Mailbox > E-invoices
Click Activate, then Start
Select IRAS GST Submissions, and click Next
Fill in the required details, and click Next
The authorized Corppass email account owner will receive an email on InvoiceNow activation
Authorize the InvoiceNow activation using Corppass
Return to Jaz, click I've Verified
If IRAS GST Submissions had been selected, the authorized Corppass email account owner will receive another email on GST InvoiceNow activation. Repeat steps 6 and 7.
Upon successful activation, you can find your Peppol ID under Settings > Organization Details > Identity.
Note: If you’ve selected IRAS GST Submissions only, you’ll first need to activate InvoiceNow via Corppass as a prerequisite. This step alone does not enable the InvoiceNow feature on Jaz, and you won’t be able to send or receive e-invoices with counterparties.
For both InvoiceNow and GST InvoiceNow
Activate GST InvoiceNow directly on Jaz, following the steps in the For GST InvoiceNow only section above
Once completed, email [email protected] to enable the counterparty e-invoicing feature on the platform
Q4. Can I change my selection(s) (InvoiceNow and/or GST InvoiceNow) after I've activated them?
Yes, email us at [email protected] to make the changes.
Q5. If my entity had registered for InvoiceNow and/or GST InvoiceNow with another platform previously, can I still use Jaz for e-invoicing moving forward?
