Choosing the data to synchronise

In the “Data type” section, tick the data you want to synchronise:

☑ Company list

Contractors, customers, suppliers

☑ Documents

Invoices, bills, credit notes

☑ Price list

Products and services

💡 Tip: You can tick any combination of options. For your first synchronisation we recommend ticking all three so that the full database is synchronised.
5

Synchronisation direction

The “Synchronisation direction” section offers the following options:

🔄 Desktop (master) ↔ Web

This is the default and recommended mode. Synchronisation runs in both directions:

  1. Import from Web: new data created on mobilna-faktura.pl is downloaded to Desktop
  2. 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.

⚡ Auto-save Desktop → Web

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!

6

Running the synchronisation

Once everything is configured, run the synchronisation:

Step 6.1: Check your settings

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
Step 6.2: Click “Synchronizuj” (Synchronise)

Press the Synchronizuj (Synchronise) button in the program window.

Step 6.3: Wait for it to finish

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!

Step 6.4: Completion

When synchronisation has finished, the progress bar disappears and the buttons become active again.

Click Close to close the window.

✅ All done! Your data has been synchronised between Desktop and mobilna-faktura.pl

Automatic synchronisation

The “Auto-save Desktop → Web” feature sends invoices to Web automatically as soon as they are saved.

How do I turn automatic synchronisation on?
  1. Open the synchronisation window (INNE → Synchronizuj)
  2. Tick the “Auto-save Desktop→Web” checkbox
  3. A message appears asking whether to run a full export
  4. Click “Yes” to synchronise all your data first
⚠️ Important before you turn it on:
  • 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
How do I turn automatic synchronisation off?

Untick the “Auto-save Desktop→Web” checkbox in the synchronisation window.

How does synchronisation work?

The diagram below shows how data flows during synchronisation:

💻 Desktop
Your computer
🌐 Web
mobilna-faktura.pl
📥 Import from Web → Desktop

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.

📤 Export Desktop → Web

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

❌ “The login or password is incorrect”

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
❌ “MySQL ODBC 8.0 ANSI Driver (32-bit) is missing”

Cause: the required ODBC driver is not installed.

Solution:

  • Click “Yes” when the program offers to download the driver
  • Or download it manually from: dev.mysql.com/downloads/connector/odbc/
  • Choose the 32-bit version (even on a 64-bit system)
  • Install it and restart the program
❌ “The 'firmy' table is empty, there is no data to import”

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
❌ Synchronisation is taking a very long time

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
⚠️ Duplicate invoices after synchronisation

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
