About this app

Your accountant for service companies under the Simples Nacional tax regime.

ContaSelf takes care of your ME or EPP service company's accounting: invoices, DAS (Simplified Tax Collection Document), obligations, and documents. You handle everything from your cell phone and speak to a real accountant when you need to.

🧾 ISSUE YOUR INVOICE IN MINUTES
Choose the client, the service, and the amount. Download the PDF or XML, cancel when needed, and reissue a previous invoice instead of typing everything again.

📊 WARNING BEFORE ISSUING
If the invoice you are about to issue could lower your company's R Factor below 28%, the app will warn you before you confirm. This is the limit that separates the lower from the higher taxation under the Simples Nacional service regime — and almost no one warns you beforehand.

📆 DAS AND DEADLINES WITHOUT SURPRISES
See what's due, with the amount and date, open the receipt for each payment, and look at the entire month on the calendar.

📄 COMPANY DOCUMENTS
Send and view your CNPJ documents directly from your cell phone.

🔐 DIGITAL CERTIFICATE
Securely send your e-CNPJ through the app.

💬 TALK TO OUR TEAM
Your question will go to our accounting team. The people who answer understand Simples Nacional (Brazilian simplified tax regime).

WHY CONTASELF?
A tax app is a tool for you to manage things yourself. ContaSelf is an accounting firm with a responsible accountant who is accountable to the tax authorities — and supports those who have grown beyond MEI (Individual Microentrepreneur).

Download and leave the accounting to those who understand the service.
Accounting services for service providers under the Simples Nacional tax regime: invoicing, DAS (Simplified Tax Collection Document), and Factor R.
