About this app

Issuing service invoices doesn't have to be difficult.

Nota Fácil was created to help freelancers, day laborers, cleaners, bricklayers, painters, electricians, gardeners, and small service providers who need to issue electronic service invoices (NFS-e) in a simple, guided, and uncomplicated way.

Many people provide services every day, get paid for their work, but get stuck when it comes to issuing invoices because they don't understand the terms, don't know what data to fill in, or get lost in the official systems.

The problem is that failing to issue invoices can cause headaches.

The client may demand an invoice later, the professional may lose larger jobs, and financial organization becomes more difficult. Furthermore, many service providers want to work correctly but need a tool that explains things simply.

Nota Fácil solves this with an experience designed for those who don't understand invoicing.

You enter the service you performed, the amount charged, and the client's data. Artificial intelligence helps organize the information and create the invoice in a clearer way.

No complicated screens.

No complicated terms.

No more getting lost without knowing the next step.

With Nota Fácil, you can:

Register your clients
Save CPF, CNPJ, phone number, WhatsApp, email, and address
Register the services you provide
Create invoices with the help of artificial intelligence
Check the data before issuing
Track your invoices in a simple list
Send the invoice to the client via WhatsApp or email
Save the information on your own cell phone
Better organize your services and receivables

The app was designed to be used by anyone.

The first time you open Nota Fácil, it explains everything step by step, in simple words. You understand what a service invoice is, why it may be necessary, and what a digital certificate is.

To issue NFS-e (electronic service invoices), in many cases, a digital certificate may be required. The certificate acts as an online identity. It helps prove that you are you when issuing tax documents.

If you don't already have a digital certificate, the app can guide you on how to get one. This service can be paid for separately.

Creating the invoice is also guided.

You can write something simple like:

“I cleaned Maria's house and charged 180 reais.”

From there, the app helps identify the client, the service, the amount, and any missing information.

Before issuing, you see a review screen to calmly revise everything.

This way you avoid errors in the client's name, wrong amount, or incomplete information.

After issuing, you can send the invoice directly to the client via WhatsApp or email.

Nota Fácil is ideal for those who want to work in a more organized, professional, and simple way.

It was made for small service providers who want to stop depending on paper, lost messages on their cell phones, or loose notes.

Main benefits:

Easier invoice creation
More organized clients
Greater clarity about services provided
Faster invoice delivery to clients
Greater security in information verification
More professional customer service

Nota Fácil is not an official government application. It is an independent tool created to facilitate the organization, completion, and tracking of service invoices.

Issuance availability may depend on municipal regulations, type of activity, provider registration, and the use of a digital certificate when necessary.

The goal of Nota Fácil is to make this process more human, simple, and guided.

If you provide services and want an easier way to handle invoices, this app was made for you.

Nota Fácil.

Your service invoice in a few steps.
