How It Works Stone meets project in three steps.
Marbull pulls live inventory straight out of distributor systems, matches it to what people are actually building, and routes the right trade to the door. No phone tag, no spreadsheets, no "let me call the warehouse".
Distributors publish
A distributor running DepotBooks flips a product on with one toggle and sets a markup. Stock, price, and lead time sync automatically as inventory moves — there is no second catalogue to maintain, which is exactly why the numbers stay true.
You search or post
Contractors search the whole network by SKU, colour, or county and compare what is on the floor. Homeowners browse the library by colour and use, then post a project with square footage, budget, and the stone they want.
The work connects
Quote requests route to the distributor holding the material. Posted projects go to contractors working that county, who bid with a number and a note. Nobody hands over a phone number until they have chosen to.
