How Jamanvar approaches staff access, audit trails, offline continuity and Indian restaurant invoicing.
Data and accessGST invoicing

Data and access

Your numbers, recipes and guests belong to you.

Jamanvar is designed with security-conscious practices, including encrypted data in transit and role-based permissions, to protect your restaurant's business information.

  • Encrypted website & data in transit

    Our website and hosted services are served over HTTPS with SSL/TLS encryption. As device-to-cloud sync features roll out, they will use the same industry-standard encryption in transit.

  • Role-based staff access

    Permissions for captains, cashiers, chefs and managers. Restrict bill cancellations, discounts and raw inventory adjustments to authorised staff only.

  • Void and discount audit logs

    Every voided KOT item, split bill, applied discount and cash drawer opening is recorded with a timestamp and employee ID, so adjustments can be reviewed.

  • Offline-first design

    Jamanvar is designed to keep billing and KOT printing working locally without active internet, syncing to the cloud once connectivity is available. Local data protection and backup safeguards are being built out as part of this architecture.

GST invoicing

GST billing built around Indian invoicing conventions.

Jamanvar calculates GST on restaurant bills, including CGST, SGST and IGST handling, based on the tax rules you configure.

Publisher details
