MarbleMap holds no stock — nothing here sits on a shelf to add to a cart and buy on the spot. Stock belongs to the supplier: only the quarry or processing plant knows which blocks, slabs or sizes are ready right now. MarbleMap isn't a catalogue, it's a demand marketplace; buying starts from what you need, not a product list.
So the real answer to "can I buy right away?": open a New Demand and describe what you're after — stone type, Quantity, finish or processing, Delivery point and the Incoterm. On Pro you can also state a Target delivery date. Verified suppliers see the demand and bid sealed, based on their actual situation. A supplier with material on hand quotes a short Lead time; one that has to produce quotes a longer one. Availability reaches you as a commitment inside an offer, not as a stock list.
Comparing offers on one screen, you can sort by lead time and pick the fastest supplier if the job is urgent. Contract, shipment and invoice sit between buyer and supplier. Buyers start free, and nothing is binding until you accept an offer.
