Because POS Ventas stores everything in localStorage, your data lives only in one browser on one device. If you clear your browser data, reinstall the browser, or switch devices, you will lose your records unless you have a backup. Exporting regularly is the simplest way to protect your business data.
Export a backup at least once a month, and always before clearing your browser history or storage.

version field is included so future versions of the app can migrate older backup formats automatically.
Export your data
Open the browser console
In Chrome or Edge, press F12 (or Cmd+Option+J on Mac) to open DevTools, then click the Console tab.
Run the export script
Paste the following code into the console and press Enter:const backup = Storage.exportData();
const blob = new Blob([JSON.stringify(backup, null, 2)], { type: 'application/json' });
const url = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = 'pos-backup.json';
a.click();
pos-backup.json. Save the file somewhere safe
Move the downloaded file to a cloud storage folder (Google Drive, Dropbox, etc.) or an external drive so it is not lost if your device fails.
Restore from a backup
Restoring data replaces whatever is currently in the app for each data type included in the backup. If you only want to recover specific records, edit the JSON file before importing to remove the sections you do not want to overwrite.
Open the browser console
Press F12 (or Cmd+Option+J on Mac) and go to the Console tab.
Paste your backup and run the import
Copy your backup JSON, then run the following in the console, replacing the placeholder with your actual backup content:// Paste your backup JSON object into the variable below
const data = { /* your backup JSON */ };
Storage.importData(data);
location.reload();
Reset to factory defaults
To wipe all data and start fresh with the sample products, call Storage.clearAll() in the browser console:
Storage.clearAll();
location.reload();
Storage.clearAll() permanently deletes all products, clients, and sales. This action cannot be undone. Always export a backup before running it.
