POS & fiscal hardware integration
A till that talks to its hardware — and keeps talking when the network doesn't.
Connecting point-of-sale and kiosk software to fiscal printers, payment terminals and government fiscal APIs, behind an interface your team can actually test against.
What's included
- One fiscal printer or payment terminal integrated end to end
- Device access wrapped behind a clean Dart or Java interface
- A simulator harness so the rest of the team can work without the hardware on their desk
- Handling for the awkward paths: interrupted sales, reprints, reconciliation after a jam
- Written handover covering the protocol and the failure modes
Process
How working together goes
No surprises, and no long proposal documents that say nothing.
- 01
A call
Twenty minutes. You describe the problem; I tell you whether it is something I have done before. If it isn't, I say so.
- 02
A written scope
What I will build, what I will not, what it depends on, and how long it takes. You get this before committing to anything.
- 03
Milestones you can run
Work lands in increments you can open and try yourself, not in a single delivery at the end. Source lives in your repository from day one.
- 04
Handover that holds
Documentation covering the protocol, the failure modes and the operational quirks — the things that are expensive to rediscover.
