Estimator — four options to choose from

Each option is a working estimator. Steps on the left, the order on the right. Order of steps: 1 · Fabric & cloth → 2 · Stitching → 3 · Hardware → 4 · Anything else. Type a window size, pick products, and the right side shows each product with its real quantity, unit, price and amount.

Prices and stock are live from the shop and read-only. Every product tile shows how much is in stock in all shops (hover, or press and hold on a phone, to see each shop). A line that needs more than the stock shows “short by …” — a warning only. Nothing here changes the shop: no order, stock or price is created or changed. Make order in each option shows the exact lines the shop app’s order form would receive, without sending them.
