Offline Mode
Also called: offline billing, offline-first
What is Offline Mode?
Offline mode lets software keep working without an internet connection, storing data locally and syncing when connectivity returns. For billing, it is the difference between a slow evening and a stopped one.
Why Offline Mode matters
Internet outages are routine in Indian markets and basements, and they arrive during peak hours. Billing that depends on a live connection stops the business exactly when it is busiest.
How Offline Mode works in practice
Test it properly: turn off the connection during a quiet hour and complete a full billing cycle. Also confirm what happens on reconnection, since sync conflicts are where offline systems actually fail.
Frequently asked questions
Yes. What matters is the invoice content and record-keeping, not whether the device was online — though e-invoicing, where applicable, needs connectivity to register.
