Local-data billing
Operational records stay on the billing PC, which keeps the day-to-day workflow close to one desk but makes device care and backups important.
Comparison guide

FAQ
Questions and answers
Does it work without internet?
Yes. After the one-time Google sign-in the app opens and bills fully offline. Internet is needed only for wallet top-ups, sending messages, Google Drive backup, Send to CA and app updates.
Can my staff or a second counter use it?
Today one PC holds one database with one owner login. There is no multi-user mode and no network sharing yet. A second PC can start from a backup, but the two copies will not stay in sync.
Where is my data, and does it ever leave my PC?
Your billing data lives in a file called crm_database.db in your Documents folder. It leaves the PC only when you choose: sending a paid message (the invoice number, amount, due date and the customer’s number or email go to our server for delivery), using Send to CA, or your own password-encrypted Google Drive backup.
