Point of sale for independent cafes.
Muster POS runs the counter, the kitchen printer, the card terminal and the online orders for a working cafe in Canberra. It was built for that shop first, which is why it covers the parts most systems leave to somebody else.
At the counter
Orders, split bills and adjustments
Split by amount or by item, per item discounts, order level adjustments and card surcharge.
Cash drawer and end of day
Till sessions, cash movements and a Z report that accounts for every refund and payout.
Printing over the shop network
Receipts and kitchen dockets to thermal printers, with a reprint queue when a printer drops off the network so no docket is silently lost.
Keeps serving when the internet does not
The till is a local application on a machine in the shop. An outage upstream does not stop a sale.
Card payments
Bank EFTPOS terminals, integrated
Linkly on premises over TCP/IP, so the amount goes to the terminal instead of being keyed in twice. Signature and operator prompts are answered on the till.
Square Terminal
Supported on the same code path, switched from the admin screen.
It asks rather than assumes
If the power goes out mid sale, the till asks the terminal what actually happened when it comes back, instead of guessing. A payment whose outcome is genuinely unknown is recorded as unknown, never quietly as a failure, because that is what leads to a card being charged twice.
Beyond the till
Online ordering
A customer ordering page with pickup times, paid online and sent straight to the kitchen.
Loyalty and reservations
Stamp cards that work at the counter and online, and table bookings including recurring ones.
Reporting and staff
Sales, product mix, payment reconciliation, rosters and timesheets.
Status
Linkly accreditation submitted in September 2026 and currently under review. Muster POS is in daily use at one venue. It is built and maintained by one developer, so it moves at the pace of the shop it runs.
