Batch traceability
01 — About
3S is an Irish software studio building the tools businesses actually need. We started in 2014 as a hosting and infrastructure outfit and have grown into a full-stack software practice covering iOS, Android, systems & control integrations, and bespoke web applications.
We're proudly small, deliberately senior, and built for clients who don't want to manage three vendors to ship one product. Our consumer-facing creative work — original games and front-of-house web — runs through our sister studio, Shadow Games & Development.
Built to run unattended at 3am. Tested. Logged. Recoverable.
Discovery, build, deploy, support. One number to call.
From a one-shop SME to multi-site operations — we scope to fit.
We meet your existing stack — ERPs, sensors, scanners, APIs.
02 — Solutions
Combine practices into a single programme — that's how most of our work ships.
Native iPhone and iPad apps for the field, the floor, and the front office. Built in Swift, deployed via the App Store or MDM.
Kotlin-first Android applications for rugged devices, tablets and phones. Released through Google Play or sideloaded for device fleets.
Process control integrations, data pipelines and back-office systems that pull existing kit into one coherent platform.
Cross-platform desktop and web tools tailored to a single workflow. Where the SaaS market doesn't quite fit, we build the missing piece.
AWS-backed hosting with cPanel where it makes sense, monitored and patched. Our original practice, still core to what we do.
03 — Industries
Every sector has its own vocabulary, regulations, and ways of working. We listen first, scope second, build third.
Internal platforms, integrations, dashboards and developer tools.
Batch traceability, audit tools, validated inventory and QC workflows.
Line monitoring, OEE, planned maintenance and control integration.
Stock, sizing, supplier and order workflows from sample to ship.
Herd, paddock, weight and movement tracking — see our cattle product.
Pick, pack, dispatch and driver-side mobile tooling.
POS-adjacent tooling, loyalty, stock takes and small-shop platforms.
Clinic-grade booking, patient comms and back-office workflows.
Don't see your sector? Tell us what you're building — we work across new sectors regularly.
04 — Projects
A sample of in-house and client deployments running on the 3S stack.
QR-tagged batch tracking from intake through release across a multi-room facility.
Live OEE dashboards pulling from PLC data with shift- and run-level breakdowns.
Android app for delivery routing, sign-on-glass and offline-tolerant proof-of-delivery.
05 — Approach
No black-box agency. No surprise change orders. Five clear stages, and you see progress at every one.
An open-ended call to understand the operation — what's painful, what's working, what success looks like at six and twelve months.
A written, costed scope document. Fixed-price where possible, transparent T&M where it isn't. You sign nothing without seeing it.
Sprints with weekly demos. Real software, in your hands, every week — not slide decks.
Staged rollout with training, documentation, and a hand-holding period. Hosting on AWS unless you need otherwise.
Ongoing care plan. Monitoring, security patches, feature releases and a person who picks up the phone.
