They didn't ask us for software.

Cashel Farmhouse Cheesemakers make farmhouse blue cheese at Beechmount Farm in Fethard, Co. Tipperary. Dozens of product lines, retailer specific requirements, and customers in nine export markets.

The weekly order plan lived in a large Excel workbook held together with macros. Dispatch, labelling and traceability information sat around it in other places and in people's heads.

Cheese is a variable weight product. A pallet is never a simple multiple of a number. Retailers want their own codes, their own paperwork and their own delivery arrangements. Orders get split across batches.

All of that detail had to be carried by people. It worked, but it depended on specific individuals being available, and every extra order or new retailer made the workbook heavier.

Before writing anything we followed the operation. Where an order arrives, what happens to it, who touches it, what gets printed, what gets checked twice, and what somebody has to remember.

The important discovery was not technical. It was that the process was sound. What was missing was a system that could hold it, so the knowledge did not have to live in a spreadsheet and a person.

We designed and built Keystone around the real workflow. Sales orders, weekly planning, batch traceability, dispatch notes, certificates of analysis and pallet labels in one place.

It handles variable weight batches, maps retailer specific product codes, supports split batch dispatch with reconciliation, tracks use by dates, and keeps a two way link with the accounting system so finance is not entered twice.

This is how we approach custom software. Understand the operation first. Build second. The result is a system that matches how the business runs rather than a product the business has to bend around.

Keystone runs live in production today across dozens of product lines and nine export markets.
