Prerequisites
Before you start synchronising, make sure you meet the following requirements:
You need an active account on the mobilna-faktura.pl portal
Login: your email address or user name
Password: your account password
Synchronisation works over a secure HTTPS connection to the mobilna-faktura.pl server.
Nothing else needs to be installed — the MySQL ODBC driver is no longer required.
Opening the synchronisation module
To open the synchronisation window, follow these steps:
In the main program window, click through the menu:
Alternatively, click the “Synchronizuj” (Synchronise) icon in the “Mobilna Faktura” section of the toolbar.
The “Mobilna Faktura” window opens with the following sections:
- Data type
- Connection settings
- Synchronisation direction
- Action buttons
Connection settings
In the “Connection settings” section, enter your sign-in details:
| Field | Description |
|---|---|
| User name | Enter the login or email address you use to sign in to mobilna-faktura.pl |
| Password | Enter your mobilna-faktura.pl account password (shown as asterisks ***) |
| ☑ Remember password | Tick this if you want the program to remember your password for future use |
Choosing the data to synchronise
In the “Data type” section, tick the data you want to synchronise:
Contractors, customers, suppliers
Invoices, bills, credit notes
Products and services
Synchronisation direction
The “Synchronisation direction” section offers the following options:
This is the default and recommended mode. Synchronisation runs in both directions:
- Import from Web: new data created on mobilna-faktura.pl is downloaded to Desktop
- Export to Web: data from Desktop is sent to mobilna-faktura.pl
Desktop is the “master” — its data takes priority in the event of a conflict.
An optional checkbox that turns on automatic synchronisation.
Once ticked, every invoice saved in Desktop is sent to Web automatically.
Important: run a full synchronisation before you turn this option on!
Running the synchronisation
Once everything is configured, run the synchronisation:
Make sure that:
- ✅ You have entered the correct login and password
- ✅ You have ticked the data to synchronise (Company list / Documents / Price list)
- ✅ The direction “Desktop (master) ↔ Web” is selected
Press the Synchronizuj (Synchronise) button in the program window.
A progress bar appears at the bottom of the window showing:
- 📊 The current operation (e.g. “Importing companies:”, “Exporting documents:”)
- 📈 The percentage progress of the synchronisation
Do not close the window while synchronisation is running!
When synchronisation has finished, the progress bar disappears and the buttons become active again.
Click Close to close the window.
Automatic synchronisation
The “Auto-save Desktop → Web” feature sends invoices to Web automatically as soon as they are saved.
- Open the synchronisation window (INNE → Synchronizuj)
- Tick the “Auto-save Desktop→Web” checkbox
- A message appears asking whether to run a full export
- Click “Yes” to synchronise all your data first
- Run a full synchronisation first so that Web holds up-to-date data
- Automatic synchronisation only works in the Desktop → Web direction
- New invoices created on Web will NOT be downloaded to Desktop automatically
Untick the “Auto-save Desktop→Web” checkbox in the synchronisation window.
How does synchronisation work?
The diagram below shows how data flows during synchronisation:
Your computer
mobilna-faktura.pl
Only new data created on mobilna-faktura.pl is downloaded:
- New companies added on Web
- New invoices issued on Web
- New products added on Web
Data that already exists in Desktop is not overwritten.
All data from Desktop is sent:
- Every company in the Desktop database
- Every invoice in the Desktop database
- Every product in the Desktop price list
Desktop is the “master” — its data replaces the data on Web.
| Data type | Order of operations | Description |
|---|---|---|
| Company list | 1. Import → 2. Export | New companies are downloaded from Web first, then the Desktop companies are sent |
| Documents | 1. Import → 2. Export | New invoices are downloaded from Web first, then the Desktop invoices are sent |
| Price list | 1. Import → 2. Export | New products are downloaded from Web first, then the Desktop price list is sent |
Troubleshooting
Cause: incorrect sign-in details.
Solution:
- Check that you are entering the correct login (email address or user name)
- Make sure the password is correct (it is case-sensitive)
- Try signing in at mobilna-faktura.pl to verify your details
- Do you sign in with Google or Facebook? See the next item
Cause: if you created your account with the “Sign in with Google” button (or Facebook), you have never set a password — signing in happens on Google's side. The synchronisation module does not use your Google account, only its own login and password, so you have to set one once.
Solution — choose one of the options:
- Set a password in the panel (recommended): sign in with Google at mobilna-faktura.pl/panel, go to Settings → Your account and fill in “New password” and “Confirm new password”. Leave the “Old password” field empty — an account created with Google does not have one.
- Or reset your password: on the sign-in page click “Forgot your password?”, enter your Gmail address and a new password will be sent to you by email.
Cause: there are no companies on your mobilna-faktura.pl account yet.
Solution:
- This is normal on the first synchronisation
- The program will download companies once they are added on Web
- Export from Desktop to Web will work as usual
Cause: a large volume of data or a slow internet connection.
Solution:
- Do not interrupt the synchronisation — wait for it to finish
- With a large database, the first synchronisation may take several minutes
- Later synchronisations will be faster (new data only)
- Check your internet connection
Cause: the same invoice was created both on Desktop and on Web.
Solution:
- Delete the duplicates manually on one of the platforms
- Use automatic synchronisation to avoid duplicates in future
- Remember: Desktop is the “master” — its data takes priority
- The exact error message
- The version of the Desktop program
- Your mobilna-faktura.pl login (never your password!)
