An example of the kind of build we do, not a client story. The persona is illustrative; the pain points are real in how this work actually runs.

Private catalogue for a serious collector

Who

A collector in his 60s with roughly 1,400 coins accumulated over 40 years (a collection well into six figures), split between a home safe and a safety-deposit box.

The pain points

The only inventory is his memory plus a 20-year-old database file that no longer opens properly. His insurer wants an itemized schedule before it will write a valuables rider, and his wife has no idea what anything is worth or who to call; undocumented collections notoriously get sold for a fraction of value by heirs.

He will not upload a list of his gold to any website, which rules out the collector platforms, and the category apps are built for the US market anyway.

What we would build

A Windows catalogue on his own computer: every item with photos, purchase date and price, grade, storage location, and current value. One click prints an insurance-schedule PDF, an estate summary for the family (what it is, what it's worth, who can sell it honestly), and a duplicates and want list for shows.

Values are updated by him or via a simple file import. Nothing ever leaves his machine.

A build like this would typically land around $850 one-time. Every real quote is fixed in writing after discovery, before anything gets built, and you see the tool working before you pay. How engagements work →
