Sales & Profit Reports

Manual sales across all channels. Profit = sale price + buyer shipping paid − item purchase cost − marketplace fees − postage − packaging − other expenses − refunds. Sales tax collected for a marketplace is excluded; enter amounts consistently.

Sync settings

Sign in with the same Google account on Android and Windows. Changes saved offline are queued for synchronization when internet returns.

Test your connection before Google Sign-In. Never share the full key.

Local mode

Google sign-in requires internet. Offline use works after the app has been opened and cached on your device.

Backup

Export a backup regularly to G:\sell\Backups on Windows. Browser storage is not a permanent backup; don't clear site data with unsynchronized changes.

Before using Android, deploy this folder to HTTPS and add that URL to Supabase Authentication → Redirect URLs. The Windows localhost address does not work on your phone.
