Tarnwick

Planning software without the enterprise price tag.

No large licence, no per-user fees and no months-long system project. The framework is already built, and each module is customised around your business: your files, your rules and the things you most need to see and act on. Prices start from the figures below for small businesses with a simple supply chain, and are agreed after a free consultation. A written service agreement sets out what is included, fees, data handling, support and how to end it.

What you are not paying for

Large planning systems come with licences per user, an implementation project and a long contract before you see a single answer. Tarnwick is built for the team that needs the answer, not the system.

No per-user licences

Add as many colleagues as you like. The price is for the modules, not the headcount.

No system project

It works from your own files. There is nothing for IT to install or integrate before you start.

No long lock-in

A six-month minimum on the licence, and a written way to end it.

Fixed, written prices

What is included, what it costs and how to stop are in the service agreement before you commit.

How pricing works

A free consultation first

A 30-minute call. We look at your files and tell you honestly whether we can help.

Starting prices for simple supply chains

These starting prices are for small businesses with a simple supply chain. A larger or more complex business is quoted after the consultation. The final price depends on how complex your business is: the number of data sources, DCs, SKUs, suppliers and special rules. It is confirmed in writing after the consultation. The licence is confirmed the same way.

Time that is clearly defined

Meetings are booked in advance and support is by email, with a reply within two working days. Unused time does not roll over.

Prices are in pounds. VAT is added only if and when it applies. There are no per-user licences.

Something that is not on the list?

The modules cover the common decisions, and we are happy to develop others. Tell us what you need to see and act on, and we will scope it and agree a fixed price.
