The week the owner cannot take off

Ask an owner-run shop what would break if the owner were away for a week and the answer is rarely dramatic. Nothing collapses. It just degrades: prices get guessed, credit gets refused to good customers or extended to bad ones, stock is not reordered because nobody was sure.

The three judgements that never got written down

What this customer is good for. What the floor price is on a negotiable line. When something is urgent enough to call a supplier rather than wait for the round.

Each of these is a real judgement built over years. None of them is written anywhere, so none of them can be delegated, so the owner cannot leave.

What a system contributes

Less than people expect on the judgement, more than they expect on the scaffolding. A credit limit per customer converts an unwritten instinct into a boundary staff can work inside. A discount ceiling on an item does the same for pricing. A reorder point removes the need to notice.

None of that replaces the owner's judgement. It records enough of the outcome that ordinary days do not require it.

The hard part is not the software

It is the sitting down and deciding what the limits actually are, which most owners have never had to articulate. That work is uncomfortable and it is the whole point; the configuration afterwards takes an afternoon.
