This guide shows you how to apply for Viva Fiscal from your Viva.com account in 6 simple steps. The service is free of charge. Once it's complete, you also activate it in Teller so your documents are transmitted to myDATA automatically.
Before you start, have ready:
your business's TaxisNet credentials (for the entity issuing the documents),
your business's internet connection details: provider name, contract number and contract date.
Step 1: Open Viva Fiscal
In your Viva.com account, select Integrations → Viva Fiscal from the left-hand menu.
Step 2: Select "Activate"
The E-invoicing with Viva Fiscal page summarises the service: it's free to activate, guides you through the AADE steps and lets you issue compliant e-invoices through a certified provider. Select Activate to start your request.
Step 3: Complete the application
In the window that opens, enter:
Internet service provider (ISP): your business's internet provider.
Contract details / number: your internet contract number.
Contract date: the date of the contract.
E-invoicing start date: the date you want to start issuing documents through Viva Fiscal.
💡 Good to know: Your internet connection details are required because, under the Viva Fiscal terms of use (clause 3.11), you declare a connection used as an alternative way of connecting to the internet.
Read the declaration, tick the box to accept the Viva Fiscal terms of use and confirm your details are correct, then select Request activation.
Step 4: Authorise Viva.com in TaxisNet
You'll receive an email with step-by-step instructions. Log in to TaxisNet with your business credentials and authorise Viva.com as your e-invoicing provider (TIN 999846755). You'll also find the detailed steps in Transmission of Documents to myDATA via Viva Fiscalisation (Step 3).
Once you're done, return to the Viva Fiscal page and select I have authorised viva.com.
Step 5: Accept the statement in myDATA
When you're notified, log in to AADE myDATA and accept the provider statement. The provider should be Vivabank Single-Member Banking S.A., TIN 999846755. Then return to Viva.com and select I accept.
⚠️ Important: The statement must be accepted within a set period. The Viva Fiscal page shows how many days remain ("Days remaining").
Step 6: Activation complete
When you see Viva Fiscal is active, your application is complete.
Next step: activate the service in Teller
To have documents from your More.com sales transmitted to myDATA automatically, you also need to activate the service in Teller. Follow Step 6 of Transmission of Documents to myDATA via Viva Fiscalisation.
