I will have a web application pos system with an offline mode.

Let's say I have a store where there are 3 web pos applications to buy products.

If my internet connection is down, I'll have to sell products offline, but how do I sync with the 3 POS on my local network?

When the internet connect is available, all data will be synced with the main cloud server.

Would you please give any suggestions on how to design the architecture or how to sync multiple web pos on a local network when the internet is down?

  • In which technology your POS system is developed? How do you do sync when the internet connection is back? – A.K.S Jan 21 '23 at 03:51
