The same account on the web and on mobile
Factura Fácil runs in the browser, on iPhone, and on Android. You sign in with the same account and see the same invoices.
Where it opens
On a computer you use the web. On a phone, the iPhone app or the Android app. That is not three signups: it is one account. A document created on the phone opens on the web once sync has caught up.
- Web, iPhone, and Android.
- A single user.
What travels with the account
Invoices, expenses, and contacts belong to the user, not to the device. The series does not change between phone and browser either. Signup is start.
Common questions
Do I need another account for the phone?
No. The same user signs in on the web, on iPhone, and on Android.
Does the phone use a different number series?
No. The series belongs to the account. The device does not open a parallel series.
