Offline-First Sales Terminal

The Sales Terminal keeps taking orders offline and syncs automatically the moment connectivity returns — proven against South African load shedding, one of the toughest connectivity tests there is.

Key Features

  • IndexedDB order queue with automatic replay on reconnect
  • Receipt numbers are never assigned locally — the same atomic database sequence assigns them at sync time, so no gaps or duplicates are possible
  • Deterministic server rejections (e.g. a blocked stock override) are distinguished from connectivity failures, so nothing retries forever incorrectly

Benefits

  • A power cut never means a lost sale or a broken tax invoice sequence
