FAQ

Frequently Asked Questions

Clear, transparent answers regarding licensing, offline reliability, WhatsApp integration, and data security.

1. Are there any hidden charges or surprise monthly fees?
Answer: Absolutely none! All software features, initial setup, staff training, and the first full year of technical support and updates are completely included in your one-time license. From the 2nd year onwards, annual maintenance (AMC) is totally optional. For the Plus plan, official WhatsApp messages are billed directly by Meta (Facebook) to your own business account at Meta's standard rates — we do not add any markup.
2. Will billing continue if my internet connection goes down?
Answer: Yes, 100%! Bill Bhai is engineered with an offline-first architecture. Instant barcode scanning, thermal receipt printing, cash registers, credit khata tracking, and Excel database sync run uninterrupted entirely on your local machine without needing an active internet connection.
3. How is my business data backed up and protected?
Answer: All transaction records and customer ledgers reside securely on your own computer inside a local SQLite database and live Excel spreadsheet (ERP_Master_Database.xlsx). Bill Bhai includes an automated 1-click backup feature, allowing you to create instant backup copies on a USB pen-drive or external hard disk.
4. What support is included after purchase?
Answer: Your license includes 1 full year (12 months) of dedicated technical support and version updates via remote assistance (AnyDesk/TeamViewer) and WhatsApp. After the first year, an optional AMC is available if you wish to retain priority support, though your software continues running normally even without AMC.
5. What is the difference between WhatsApp delivery in Basic vs. Plus?
Answer: The Basic plan utilizes standard WhatsApp Web linked device gateway, which is free but subject to Meta's end-user policies regarding bulk marketing. The Plus plan integrates directly with the Official WhatsApp Cloud API, ensuring verified business delivery, official green-tick support, automated bill dispatches, and zero risk of message restrictions.
6. What happens if my computer crashes or Windows is reinstalled?
Answer: Simply keep a backup copy of your database folder or Excel workbook on an external drive. In the event of a PC failure, our support engineers will remotely install Bill Bhai on your new computer and restore your complete inventory, customer ledgers, and transaction history in under 15 minutes.
7. What can I expect during the Free Demo?
