Our service providers, both Petrobras’s and its subsidiaries’, can consult the ISS withholding receipts in the
Wiss system. Receipts are available every month, due to the tax calculation of the ISS that was withheld. A receipt is issued for each invoice filed by the service provider.
To access the
Wiss system, suppliers must have an e-mail registered on our database, and a password will be issued for them. Those who have not yet registered their e-mails should contact the contract inspector.
Before accessing
Wiss, having their passwords, it is necessary to update the registry to enable access to the system, which can be done by clicking
here. Login is made using the supplier’s Taxpayer’s ID (CNPJ/CPF) (“key” field), a Taxpayer’s ID (CPF) to register who made the change (“identification document” field), and the password we sent by e-mail.
It will be only possible to access
Wiss and generate ISS receipts after the registry has been updated.
