Getting started
To use the 16it apps (Autofaktury, Autosignly) you need a 16it account and at least one company. This page walks you through registering an account and adding your first company.
1. Create an account
Open the 16it sign-in page. If you don't have an account yet, click Don't have an account? Register (Nie masz konta? Zarejestruj się). You can also sign up with Google.

Enter your e-mail and a password (or continue with Google) to create the account.
2. Activate your account
After registering you receive an activation e-mail. Open it and click Go to the site (Przejdź na stronę) to activate your account.

3. Sign in
Go back to the sign-in page and log in with your e-mail and password (or with Google). Use Reset password (Zresetuj hasło) if you ever forget it.
4. Add your company
On your first sign-in you are asked to add a company. Fill in the required fields
(marked with *):
- Country, Tax ID (NIP) — you can pull company data automatically by NIP using the cloud icon next to the field,
- Name and address (city, postal code, street, building number),
- Phone number.
Then click Add company (Dodaj firmę).

Once the company is saved you can select it in the company picker at the top of the app and start working.
