Most reseller tooling assumes a product database: scan the code, pull the title, done. That assumption fails completely on a Victorian side table, a piece of studio pottery with an unclear mark, or a run of estate silver. Each item is singular, its identification is partly a research task, and what you write about it is a substantial part of what you are selling.
Instica is built to hold that. Records are created from your own description, photographs and measurements rather than from a lookup, and the research you do — the maker mark you identified, the estate the piece came from, the repair you found on the underside — stays attached to the item permanently rather than living in the listing you will eventually take down.
