Nota Salvador is a mobile application developed by Prodam SP that allows users to issue invoices from their smartphones. The app is compatible with any smartphone model and presents several features for both service providers and customers.

For service providers, the app enables the issuance, cancellation, and real-time sending of invoices via email. It also allows them to consult and view issued, received, and canceled invoices, as well as to configure and change their company's data.

Customers, on the other hand, can consult received invoices, search for nearby service providers, check generated tickets for monthly draws, and view available credits. They can also configure and change their profile data.

Additionally, the app features a locator for service providers in the capital. It locates registered establishments by name, neighborhood, location, and distance, as well as by branch of activity. It also calculates routes to the nearest providers on foot or by car and presents their location on a map.

Nota Salvador is a program that encourages citizens to request the fiscal document when contracting any service in Salvador city, and it returns part of the collected tax (ISS - Service Tax) to the population. The credits can be used for up to 100% discount on IPTU, deposited in a checking or savings account, or as participation in monthly cash prize draws.
