Web application for a turf farm

We run a family sod farm and need a web application built around how the turf business actually works. The public catalog should display grass varieties by type (Kentucky bluegrass, fescue, Bermuda, zoysia) with sun and shade tolerance, mowing height, drought resistance, and price per square meter or pallet. The heart of the application is a coverage calculator: the client enters lawn dimensions or roughly outlines an area, and the app converts the area to rolls or slabs, adds a buffer for trimming, and outputs the number of pallets and total cost. Orders are placed strictly by actual area, not fixed packages. Because sod is perishable, delivery planning must account for a fresh-cut guarantee: cutting happens on delivery day or the day before, so the calendar blocks cutting windows when the daily quota is exhausted, and warns if the selected date falls outside the guarantee. We need a laying crew option with a separate per-meter rate and its own schedule slots. We also serve landscapers, so we need wholesale accounts with tiered pricing, payment terms, regular weekly orders, and order repeat from history. Admin side: daily cutting quota, seasonal variety availability, delivery zones and routes with fees, order status from cutting through loading and delivery. Priority is mobile design—crews and buyers order straight from the field.
