Tarnwick analyses your stock, orders, containers and sales, then recommends the best action for each decision, built around your business and in minutes rather than hours.
Over 20 years in supply chain and commercial roles, I’ve built a career solving the problems that cost businesses money: optimising stock across global suppliers with different lead times, managing factory closures and vendor challenges, and making the call on when to expedite or cancel orders to keep stock lean. I’ve restructured warehouse space for capacity, reported on critical paths from order to shelf, and balanced availability against cost, always turning complex, data-heavy decisions into clear actions. Tarnwick is built from that experience: the tools I wished I’d had, doing in minutes what used to take hours of spreadsheet work.

A finding without an action is a chore. Every warning ends with a step, a quantity and a date.
"12 units a week, runs out on 14 October", not "running low".
Red means act today and appears only where it does. Nothing flashes, nothing shouts.
A figure on the overview matches the same figure everywhere else.
We are early stage and building the process with you. You get direct attention and a say in what we build.
A written service agreement sets out what is included, fees, data handling, support and how to end it, so everyone knows where they stand.
Support is by email, with a reply within two working days. Calls are booked in advance at agreed times.
We cannot offer same-day fixes for now. If a refresh fails, your dashboard keeps working on the last good data.
