Your job lives in seven apps. None of them talk.
The estate, the books, the pipeline, the email thread and the WhatsApp group. Brassturn is the hub in the middle, so a finish agreed in a chat becomes a priced line with an orderable part number and a record of who agreed it.
Every line traceable to a real item number and a landed cost. Duty and freight in, never list price.
Who agreed what, on what date, through which channel, with the evidence attached.
Every job group is a contact list nobody wrote down. Names, roles and who signs, filed against the property.
Licences expiring, credentials burning down, a catalogue line still unverified. All before it costs you.
The configured item number goes straight to the vendor eStore. No re-keying, no transcription errors between what was agreed and what was ordered.
