BillBasket runs on a Windows computer at the counter and on Android phones for staff on the move — the same store, the same data, working together over your shop’s own Wi-Fi. The Windows machine acts as the host; phones pair to it as companions and bill against the same live data, with no internet connection required.
This works over your shop’s local Wi-Fi network — it isn’t internet-based. Both devices must be on the same network, so a phone taken off-site won’t reach the counter machine until it’s back on the shop Wi-Fi.

​
Understanding the fields

​
On the Windows host — Settings → Web Access

  • Enable Web Access (toggle) — starts the local server on the desktop so phones can connect. Nothing can pair until this is on.
  • Port — the network port the server listens on; the default is fine for almost everyone.
  • This device’s addresses — the list of the PC’s Wi-Fi addresses, shown so you (or the phone) know where to connect.
  • Pairing QR + 6-digit code — a phone scans the QR (or types the rotating code) to request pairing. The code rotates for security.
  • Approve / deny prompt — when a phone tries to pair, the desktop pops a request to approve — protected by your Admin PIN if one is set, so a stranger can’t pair a device without you.
  • Paired devices — the list of phones currently paired, where you can revoke a device (cut it off) or turn on Require PIN for it. Revoke is how you remove a lost or replaced phone.

​
On the phone — companion mode

  • Pair to a host — the phone scans the host’s QR (or enters the code) to join. Pairing is a one-time step; once approved, the phone remembers the connection for future shifts.
  • What a companion can do — a paired phone bills against the host’s live data. A phone signed in with a view-only role can browse but not check out at POS, so you can hand a floor phone to junior staff safely.

​
See it on your device

Settings → Web Access before pairing anything — the server is off (“No data is exposed to the network”), with the Port and Token validity fields at their defaults, and a Network adapter picker below listing every network interface this PC has (Wi-Fi, Tailscale, virtual adapters) so you can choose which one the pairing QR/link should use.

1

Turn on Web Access on the counter PC

Rajesh Sharma runs BillBasket on the Windows PC at the counter — the host that holds the store’s data. He opens Settings → Web Access and turns it on, and a pairing QR appears.
2

Pair a phone over Wi-Fi

Suresh opens BillBasket on his Android phone (on the shop Wi-Fi) and scans the QR. Rajesh approves the request on the counter PC, and the phone is paired.
3

Bill a customer from the phone

During a busy hour, Suresh bills Meena Devi’s purchase directly from his phone while walking the aisles, instead of making her wait at the counter.
4

See it on the counter instantly, and revoke when needed

The invoice appears on Rajesh’s counter PC right away over the local network. When Suresh’s phone is later replaced, Rajesh revokes it from the paired-devices list in one tap.
