A measured offline promise

Keep selling. Know the edge.

Cash and named manual-tender sales complete through a connection loss, after device setup, in your browser.

See the product
  • Browser-only
  • After device setup
  • 500 queued operations
  • 24 hours without sync

Bounded offline is included on every plan.

The line is literal

What survives the connection loss.

Tillo requests persistent browser storage after setup. Durability grade: high when granted. If the browser declines, Tillo says so before you depend on offline checkout.

Works offline

  • Cash and transfer
  • Manual external-card reference — no bundled provider
  • Mixed tender, cart and change
  • Receipt printing with a provisional reference

Needs connection

  • Device registration
  • Initial catalogue and policy sync
  • Most integrated card terminals
  • Privileged corrections

Operate the boundary

Three warnings. One precise stop.

Drag or use arrow keys. The parallel 24-hour ceiling has the same consequence: only a new offline sale pauses.

A retry is not a second sale

One operation. One receipt.

At Almacén Rivera, María García records Café Sur 500 g ×2 for $17.00. Cash is $20.00; change is $3.00. The retry changes the mapping, not the sale.

Recovery stays available

Nothing is trapped in the browser.
